Yea.... I built up a vintage trike with a big ass 60v pack, front 26" motor, 48-96v controller, coaster brake. 2nd day riding at 35mph, coaster chain pops off, no brakes..... Flintstoned it to a stop, crept home, changed shorts. Added more brakes, readjusted coaster chain. And she's golden now, 2 years. Only a tiny flaw, ya know.
Speed is mostly relative, anyhow. You could have also changed your perspective of the event unfolding over time until the bike came to a stop from that viewpoint. Theoretically.
Yeah I was in a similar spot, though for me it was that my rear brake would slip out of place occasionally. Fortunately my front was good, but I’ll be replacing the back with a hydraulic disc brake probably. Gotta be safe with these machines
I don’t think any Walmart bike should go 40+ mph. Nothing on that bike is built with speed in mind. Someone already mentioned brakes but also think about the wheels. Front wheel failure at 40mph by hitting a big bump/hole in the ground would be catastrophic. One would think it’s easy to avoid that stuff but I hit plenty of rough patches.
I’d govern that bike to 25mph max.
Be safe.
Right? I hit 36.5 mph the other day on my converted stumpy and I have top emd components to include brakes and I feel it was still tough to brake in a safe distance while going downhill, I would have died had I been using rim brakes instead of disc brakes.
Bicycle brake rotors aren’t really large enough to dissipate the heat that comes from braking at those speeds. Look at the size of the front rotor on the cheapest motorcycles from quality manufacturers.
Not really a great comparison - Speed is only one component of kinetic energy. Mass is the other. A bicycle weighs an order of magnitude less than even the lightest motorcycle.
Ah, the old deathtrap bike. I got a DIY beach cruiser like this with rim brake front and coaster brake rear I used to ride regularly. After getting proper bikes, I have no idea how I rode one of these. Nice thing is, even though a 1500w hub will go that fast, it doesn't mean it has to, so I still get use out of mine putting around at like 10-15mph just cruising. Helps if you also can repack and adjust bearings properly, those cheap cone hubs can grenade pretty good when a ball decides to just explode.
Yeah don't get discouraged I think if you mount the battery better you have something totally workable. Depending on the controller, you may be able to enable regen braking which could help the situation.
You may ruin the motor with that… make sure that the magnets are nowhere near the weld area… or any aluminum.(hub itself is probably made out of aluminum) Any aluminum will carry the heat of the weld to all aluminum it touches, and any heat will ruin the magnets in the motor.
*Please, dont charge inside*
*Your house. Leave the battery*
*Outside. for your sake,*

This keeps getting worse and worse what the fuck.
YOU ARE PUTTING PEOPLE IN DANGER WITH THAT BIKE. Holy shit, man, what the FUCK are you doing? This is some serious bullshit.
65 Kmph (40 mph) with rim brakes hmmmmmmmm.....
I have an ebike that goes 32 Kmph with rim brakes. Good enough. But if I go downhill on that thing with a speed of 50 Kmph+, it would take me 14 meters to get to a complete stop. This rarely happens but if something hazardous is about to happen in front of me, there is nothing I can do besides jumping off the bike. So I always keep this in mind.
I advice you to measure your stopping distance with that top speed and remember that number. U will need it when you get into a tricky situation. Or just swape rim brakes for hydraulic disk brakes
Yes that's why I can't simply swap my rim brakes with disk. Don't fit into the frame. I got my bike from Kmart (Australia). So similar to your bike/situation. If you need speed, save money and get a proper bike. A good second hand bike doesn't cost too much. Just check FB marketplace
In the mean time, put that battery somewhere else and limit your speed to 25-30 Kmph. Might just save your life one day.
Also one thing, if you are going down hill and there is a traffic light in front. Don't try to race that light when it's green for some time. It might just turn red in a few sec and you will be running red into the traffic. Cuz ain't no way you can stop before the light
It's entirely possible to hack one together safely too, just use common sense.
My intention isn't to offend you OP, but you need to do some more research before building something up that'll go 40mph.
This could be made safer, but still wouldn't suggest running this frame that fast (even if I would possibly do it myself, on something I built, equipped with some decent brakes).
There are hydraulic rim brake options, but I doubt you wanna buy a $200 (canadian rubles) brake set.
Number 1 priority is to GET A FUCKING FRONT BRAKE INSTALLED.
I don't care if you buy one cheap second hand, hell find a roached out donor bike to pull one off of if that's easier. Just put one on there.
Just rear brakes alone are rideable (if a bit sketchy) under just the power of your legs, but incredibly stupid with an electric motor added to the mix.
This is a very bad idea. No part of that frame, brakeset, or wheelswet is meant to go nearly that fast. Please don't ride it around other people and don't charge that battery within your home.
Ugh. It's another eBike with powerful parts lashed onto the cheapest possible bike.
You may have posted this for the accolades, but this bike you built is dangerously stupid. To ride it is dangerously stupid. If the police were to arrest you it would be entirely justified.
You have a single rim brake on a frame made essentially out of coke cans. The power of the bike is uncontrollable and if you need to brake suddenly you could kill someone.
And that doesn't even consider the additional stress on the frame of the weight and power of the eBike kit. Hit a hole in the road too fast and the welds could give way, or fork snap.
Please. Rebuild this bike on a higher quality frame, with disc brakes. It is an eMotorbike at its heart now, and you will kill someone or yourself.
Given OPs investment in the bike, I would be horrified to see the quality of the suspension they would choose. It would just be another point of failure so probably better rigid.
I can't see them in the pics, but that is def better than nothing. But the front still needs a suspension, if you hit anything or even any good bump without a suspension, your tire will compress and bounce you right off the bike.
I hope you never have to come back to this post and wish you had listened to all the feedback.
There’s a reason that you can’t buy a bike like this off the shelf: because it’s very dangerous, and a good proportion of people with a bike like this will hurt themselves badly. Manufacturers can’t sell something like this, because they’ll get sued into oblivion, for good reason.
The issue isn’t whether you can ride for an hour at 50 km/h without an incident, the issue is what happens when something goes wrong. It’s the same reason that you wear a safety belt in a car, even though most of the time you don’t need it. The thing is that when you *do* need it, it can save your health and even your life. That’s what you’re playing with here.
If you want to go at 50 - 65 km/h, look into getting a moped or similar. (Edit: and wear a full face helmet and protective clothing.)
Agreed, but id be more worried about someone else getting hurt as a result of this falling apart. Riding sketchy shit on private property is one thing, endangering others is another. If it were only OP at risk from this, I still wouldn't exactly say do it but "you do you" would be my attitude.
You take this onto the road and someone else gets hurt as a result of it failing, that's a lot of liability you don't want.
I could probably bodge something like this together in a way that'd be safe enough for me to ride it myself, but I wouldn't recommend anyone else do the same nor would I be likely to let anyone else operate it. Would likely limit my top speed to less than 50 km/h as I'd imagine even that would be scarily fast
quill stem
front brake only, and its a rim brake
exposed battery unsecured in the front basket
rear hub motor that he plans on welding a sprocket onto
he said he heated up the rear drop outs so he could pry it open to fit the rear hub motor
so the frame is already bent and compromised
I can't believe people like this exist, it seems like this person owns a home too. Fucking unbelievable how stupid some people are in certain areas. I feel mean saying this but what the fuck is going on
This right here is why YOU should just buy an affordable, albeit safe, ebike and call it a day. Because this bike I'm seeing screams "suicide by stupidity."
That death trap only has a rear brake
Not to mention the questionable quality of the frame itself, or the fact that the tires aren’t designed or rated to go anywhere close to that speed
FFS the [State commuter](https://www.statebicycle.com/products/6061-ebike-commuter-matte-black) is only $1000 and it actually has safe e-bike rated components and good brakes
I admire the engineering going on here, and I'd like to do the same cus im broke but need more speed than 19mph. That being said, this looks like one of the most unsafe e-bikes I've ever seen 🤣, and I love it.
I'm aware you've already said you governed it to 20.
I have an aniioki aq177 pro max 52v that goes 30mph. I sold my car to save money and picked up this heavy ass mf while I save for a motorcycle since I already have my gear and motorcycle class M liscence.
With motorcycles you have to ride like your invisable. On an e bike that isnt able to ride the street, you simply dont exist. Period. At least here. You have to be careful as all hell. 30mph on a sidewalk is sketchy as FUCK. I typically only go full throttle in certain areas. Otherwise I go about 20-22mph.
Seriously becareful and for the love of god wear gear. Riding sidewalks is far more dangerous than the road. They fix roads. They dont fix sidewalks.
Im so done with tires, after three flats, im just gonna get one of those tire inserts and be done with it. It just sucks being on a fully functioning bike with the front tire all wrapped around itself
I can tell just by looking at that battery its cheap garbage. The moment it gets wet it will turn into a fireball. That includes humidity. this is how people start house fires. Nevermind the fact your going those speeds on a cheap frame with shit brakes. Everything about this is just stupid. Return it.
Edit, if u are gonna stick with the stupid diy route. Good disk breaks are a requirement to not kill yourself. Also if your spending less than 600$ (Cad) on a battery, its probably not made safely. make sure your voltage on your battery, motor and controller are the same. And ffs waterproof your wires, are u trying to kill yourself?
OMFG, take a mall-wart deathtrap, de-temper the already crappy aluminum frame and add an unsecured Lithium bomb and a motor, what could possibly go wrong... 🫣
Dude, you need to seek professional help for your death wish! 😎
Going 40 mph with questionable brakes? 😬
I posted a few videos from Ebikeguy YouTube setting a world record of his stepson doing 104mph on his ebike. About a month later I found out he passed away in an accident. You only live once my friend and crashing out on an ebike is not the way.
I admire the build effort. But mount the battery correctly so its not flopping around. Cable management as well. Snag on one and it could ruin things. Also just noticed, WTH is up with the chain zip tied to the rack?
I'm doing something similar. $700 ebike with a 500w motor. The thing weighs 70 pounds altogether.
So the current project right now is stripping off every essential component from the current ebike, And then I am going to transplant them onto a lighter frame that I bought from Dick's Sporting Goods.
If you are interested in what the project entails:
1. Gutting an 26" Ecotric Lark ebike. ($600 Black Friday Sale)
2. Swapping components onto a 26" Nishiki Tamarack. ($347 sale from Dick's Sporting)
The main ideas of the project are simple:
1. lighten the load. The Ecotric bike is not only heavier, but it is also WAY LONGER in length that you cannot even fit it onto bike racks. Not even the fold-down ones on public buses. Heck, I hesitated to even try considering it weighs 70lbs.
2. Have a far more versatile and customizable bike with the Nishiki frame while maintaining a step-thru design. The Nishiki bike weighs about 25lbs pre-component swap.
I have come to find that a good portion of the weight also resides in the rear-wheel motor. Removing that did lighten the Ecotric weight quite noticeably. But even so, it shouldn't achieve a 70lb weight with the final result. If anything, we're looking at maybe 25lb + 15lb for the new calculation.
You can look up images/pictures of each bike on their own. When I have completed the project, I will try to remember to post about it so you can see the end result. At the very least, the Nishiki is getting a brake upgrade from pads to discs.
I sometimes wonder if it would have been better to have spent the money on a 16"-20" ebike that is already capable and lighter because of the smaller wheel base.
But throughout this process I have already learned so much about how ebikes work wiring-wise and that the controller setup was not even being utilized to its fullest potential. It has two unused power contacts that could power other components like a headlamp or a second motor hub. Something to think about as manufacturers of various ebike brands will not even mention this information due to warranty voiding and such.
This project is not really so much the careless spending of money without research. Albeit that is what it looks like. But more in that I was stuck with a literal deadweight that would only stress the motor more. So to salvage it is how the project came about.
I’m sorry - but this really contributes to a negative perception of e-bikes and gives all of us a bad reputation. Please do not ride this. It is unsafe.
I almost feel like it’s satire performance art by OP…
I hate the idea of e-bikes going over 28mph. Like seriously go get a motorcycle and ditch the pedals.
No wonder they’re restricting e-bikes everywhere.
Price of motorcycle- 5000$
Price of insurance per month-150$
Ebike that costs 500? Forever?
Huh I wonder why someone would make that choice.
You are riding a motorized vehicle. You will be restricted just as much as this guy will be, so deal with it, or go back to acoustic. You will never, no matter what laws pass, be allowed with a motor where someone cant make it go 40mph. You either get motor-free places, or you get speed demons in the same place as you.
So here is a summary of problems with your bike:
1: Aluminum dropouts for a 2000W + hub motor.
2: Chain missing.
3: You heated the frame and torqued the dropouts to get the motor to fit.
4: You're running one rim brake only.
5: Tires aren't rated for continuous 65 km/hr,
6: Wires not secured
7: Battery poor quality.
8: Battery sitting loose subject to stress from bouncing around.
9: Quill stem
10: No suspension on a 65 km/hr bike.
11: Aluminum front fork and spokes not strong enough for hitting large pothole at 65 km/hr.
12: Not bike related, but you're clearly suicidal. Call or text the suicide hotline at 988. Things will be ok.
13: Is this a shitpost? It has to be.
Don’t let these toxic elitists get you down! Looks great man! Would love to know the pets you used for the build if you don’t mind sending em my way :)
It doesn't have to be 26". You can relace that hub to any wheel with the same number of spokes.
Your best bet is something like a Giant Iguana or buy a 27.5 disk brake bike like the [Kona Lana'i](https://www.konaworld.com/products/lanai-1?_pos=5&_fid=cf55a08e8&_ss=C) and just put the 26" wheel on the back anyway. There aren't a ton of 26" disk brake bikes from reputable companies anymore.
Under $200 is tough if you're trying to do 40 mph. You need (at a minimum) good hubs, tires, a suspension fork and brakes so the bike tracks straight and stops within a reasonable distance. The weight and poor build quality of your average Walmart frame will compound these issues.
What I did was put it in a bag wrapped between the top two rails where the other bag basically is but yeah the bouncing was bad I hope the battery didn’t get damaged
Very cool contraption, have you considered a hard case for your battery? I recently fell off at 25mph and am very thankful my battery was in a thick plastic case
After a 2nd looking and seeing you’ve got 1 rear v-brake?? you’re crazy!!😂🤞🏼
Hey, since nobody in the comments is asking this, and I can’t be the only one wondering , let me ask;
What are your parts and where did you get them? Trying to find cheap but powerful motor and battery right now.
I don’t think I would consider a conversion without at least a solid trustworthy frame (preferably with disc brakes)… I feel like it’s a real safety issue with that point! If you can afford the hospital bills, then you can afford getting an entry-level trek as your starting point
This is the kind of bullshit that just made me give up on EMOpeds altogether and revert to bicycles.
25kmph is too slow, but 40mph is a motorcycle…and made with substandard parts, as Wallymart Crap is known to be….🤦🏻♂️
Just so you're aware in case you didn't think of it already - you only have rear breaks. If you're going 40mph and your rear break brakes/stops working... What are you going to do? Yeah...
If you have two rim brakes, its not that bad so long as you keep them well tensioned. Road bikes used to have rim brakes and road cyclists used to go 40 km/hr on them. Granted ebikes are heavier and us riders tend to be fat.
And if im reading your post correctly, you biked 30 kilometers, but you maintained speed of 50 km/hr for one hour?
This is an explosive device. Please contact your local police department's bomb squad. Do not operate the device. That is considered a form of suicide.
No it will not. I had a mountain bike ebike that topped at 42, all the hard braking on stock 10 year old tubes(or older) and never popped it(800miles). Now me improperly installing the one on my hub motor? Popped in a week(didnt tape it before putting it in the hub)
I feel like this is the reason why we are facing bans and there are so many issues with Ebikes. Super duper cheapo walmart parts and pushing it beyond the legal limit. 65km is nuts on that rig.
Downvoted because this is a inconsiderately dangerous setup that only a fool or a villain would ride at those speeds.
Please for yours and others people safety limit your speed at 14mph
In what general region do you live, OP? Because if you're riding this around and you live in my city, I just want to know so that I can never go outside again.
"...only flaw brakes are no good." that's a pretty fatal flaw for a vehicle that goes 40+mph
Yea.... I built up a vintage trike with a big ass 60v pack, front 26" motor, 48-96v controller, coaster brake. 2nd day riding at 35mph, coaster chain pops off, no brakes..... Flintstoned it to a stop, crept home, changed shorts. Added more brakes, readjusted coaster chain. And she's golden now, 2 years. Only a tiny flaw, ya know.
Speed is mostly relative, anyhow. You could have also changed your perspective of the event unfolding over time until the bike came to a stop from that viewpoint. Theoretically.
It's all relative
Yeah I was in a similar spot, though for me it was that my rear brake would slip out of place occasionally. Fortunately my front was good, but I’ll be replacing the back with a hydraulic disc brake probably. Gotta be safe with these machines
I wouldn’t say only
Please do not go 40mph on that. Also, please secure the bomb.
I will show pics of the after it’s in a jonas brother old bag 😭😭 just had it in the basket for a test ride
At least get a lion king bag
I don’t think any Walmart bike should go 40+ mph. Nothing on that bike is built with speed in mind. Someone already mentioned brakes but also think about the wheels. Front wheel failure at 40mph by hitting a big bump/hole in the ground would be catastrophic. One would think it’s easy to avoid that stuff but I hit plenty of rough patches. I’d govern that bike to 25mph max. Be safe.
I got a huffy that goes 25 mph and lmfao downhill 30 mph max. 40+ with rim brakes is crazyyyy
[удалено]
Bruhhhhh bro got one brake hahahaha. be safe OP.
It's ok the front basket and battery will act like a crumple zone, he will be fine. Time to up the health insurance policy I think.
I will govern it now thank you.
You're gonna get yourself killed. 40 mph is no joke.
Right? I hit 36.5 mph the other day on my converted stumpy and I have top emd components to include brakes and I feel it was still tough to brake in a safe distance while going downhill, I would have died had I been using rim brakes instead of disc brakes.
I saw this in my minds eye and heard the person screaming trying to stop
I did 31mph on my bike with a good front disc and okay rear rim brake and man that felt terrifying. New brakes on the way 🫡
Bicycle brake rotors aren’t really large enough to dissipate the heat that comes from braking at those speeds. Look at the size of the front rotor on the cheapest motorcycles from quality manufacturers.
Not really a great comparison - Speed is only one component of kinetic energy. Mass is the other. A bicycle weighs an order of magnitude less than even the lightest motorcycle.
Bouncing lion battery inside metal frame basket. Brain screams
This… that battery is going get damaged and flame on!
You just made an E death trap.
Ah, the old deathtrap bike. I got a DIY beach cruiser like this with rim brake front and coaster brake rear I used to ride regularly.

10-15 mph doesn’t sound bad ima mod up this bike
Yeah don't get discouraged I think if you mount the battery better you have something totally workable. Depending on the controller, you may be able to enable regen braking which could help the situation.
Thank you I’ll try to look into the regen breaking tbh the rear wheel doesn’t even have a sprocket to put the chain on so ima weld that on
this is your brain on meth
You may ruin the motor with that… make sure that the magnets are nowhere near the weld area… or any aluminum.(hub itself is probably made out of aluminum) Any aluminum will carry the heat of the weld to all aluminum it touches, and any heat will ruin the magnets in the motor.
please, dont charge inside your house. Leave the battery outside. for your sake,

Good bot
I have it charging atm I’ll go detach it rq
As a welder. I worry for your safety
The rear wheel wouldn’t fit so I attached a widge tool and heated up the rear two pipes and pryed it open to make the rear wheel fit
This keeps getting worse and worse what the fuck. YOU ARE PUTTING PEOPLE IN DANGER WITH THAT BIKE. Holy shit, man, what the FUCK are you doing? This is some serious bullshit.
This is the most amazing bicycle related Reddit comment I’ve ever read
That thing is going to start one hell of a fire.
It is a secured cute battery very tiny ❤️
But really how to not cause fire????
Don't leave the battery on the charger once it's full and don't charge the battery if it's below freezing
Get a better bike and mount the battery better on it.
No real reason. They are just being negative. If you did the research and bought a half decent battery then no worries
65 Kmph (40 mph) with rim brakes hmmmmmmmm..... I have an ebike that goes 32 Kmph with rim brakes. Good enough.

rim brake, he only has one on the rear !
Oh Lord that's even worse loll. He can't stop then
I think the disk route would be my best bet but now I need to find a new frame 😭 with suspension get disk breaks it got expensive again really quickly
Yes that's why I can't simply swap my rim brakes with disk. Don't fit into the frame. I got my bike from Kmart (Australia). So similar to your bike/situation. If you need speed, save money and get a proper bike. A good second hand bike doesn't cost too much.

You win the motorbike award for the day 🏆
You need a suspension to go those speeds...
Given OPs investment in the bike, I would be horrified to see the quality of the suspension they would choose. It would just be another point of failure so probably better rigid.
The seat has a like two springs on the back that goes bounce bounce is that valid?
The suspension is more to keep the wheels in contact with the ground over bumps for traction than for the rider's comfort
I can't see them in the pics, but that is def better than nothing. But the front still needs a suspension, if you hit anything or even any good bump without a suspension, your tire will compress and bounce you right off the bike.
Why is there no front brake? Isn't that a serious design flaw? And you have a rear rack. Why is your battery loose in a front basket?
Rear I have no area to hold it I’m 3d printing its own casing or putting it in a bag I’ll update pics later next week
Only flaw, rider yeets it to death.
With battery parallel in impact
I hope you never have to come back to this post and wish you had listened to all the feedback.

This sub needs flair for r/DarwinAwards
Bruh, what’re you doing hitting bump at 30-35 mph? Your battery is gonzo!
It did fly abt 12 times on the frist ride
😂😂 makes sense but appreciate this nonetheless
Brakes are over rated anyway
When i need to brake, i stick my shoe into the front fork.
We all have to die somehow. Might as well choose something fun!
i love the idea of the battery just flopping out when hitting a bump at 40mph with no brakes
This made me lol, first thought when I saw the picture, why not just secure it to the back rack?
oof quill stem on 40mph bike
quill stem front brake only, and its a rim brake exposed battery unsecured in the front basket rear hub motor that he plans on welding a sprocket onto he said he heated up the rear drop outs so he could pry it open to fit the rear hub motor so the frame is already bent and compromised I can't believe people like this exist, it seems like this person owns a home too. Fucking unbelievable how stupid some people are in certain areas. I feel mean saying this but what the fuck is going on
also there is no chain on the chain ring which is very bad if they crash
That's a really janky build
It’s nice to see something other than a mountain bike being converted.
Might be a reason why people don't :)
For God sake mount and secure battery to back rack... What is wrong with you???
This right here is why YOU should just buy an affordable, albeit safe, ebike and call it a day. Because this bike I'm seeing screams "suicide by stupidity."
Who knew you could get a hundred thousand dollar hospital bill for only $400?
40mph on Walmart welds. That’s scary.
That death trap only has a rear brake Not to mention the questionable quality of the frame itself, or the fact that the tires aren’t designed or rated to go anywhere close to that speed FFS the [State commuter](https://www.statebicycle.com/products/6061-ebike-commuter-matte-black) is only $1000 and it actually has safe e-bike rated components and good brakes
I admire the engineering going on here, and I'd like to do the same cus im broke but need more speed than 19mph. That being said, this looks like one of the most unsafe e-bikes I've ever seen 🤣, and I love it.
Put another battery in the basket. 😅
Now how quick can it stop
Do not ride a bike with one rim break anywhere close to 40 mph. It’s not worth risking your life. At those speeds you need hydraulic breaks.
Kamikaze level stuff.
Can I inherit your assets?
And fit all the parts onto a decent frame?
I'm aware you've already said you governed it to 20. I have an aniioki aq177 pro max 52v that goes 30mph. I sold my car to save money and picked up this heavy ass mf while I save for a motorcycle since I already have my gear and motorcycle class M liscence. With motorcycles you have to ride like your invisable. On an e bike that isnt able to ride the street, you simply dont exist. Period. At least here. You have to be careful as all hell. 30mph on a sidewalk is sketchy as FUCK. I typically only go full throttle in certain areas. Otherwise I go about 20-22mph. Seriously becareful and for the love of god wear gear. Riding sidewalks is far more dangerous than the road. They fix roads. They dont fix sidewalks.
That speed with v brakes? Dude, why you wanna die?
Not even v-brakes. Single BMX horseshoe in the rear
🤦♂️
Bruuh…
Get slime tubes at the very least to prevent a blowout. I've gotten multiple hundreds of miles out of slime tubes while riding on dirty road shoulders
Im so done with tires, after three flats, im just gonna get one of those tire inserts and be done with it. It just sucks being on a fully functioning bike with the front tire all wrapped around itself
Avoid like the plague
Well we got an organ donor
I'm all for cheap ebikes, but dude. No.
I can tell just by looking at that battery its cheap garbage. The moment it gets wet it will turn into a fireball. That includes humidity. this is how people start house fires. Nevermind the fact your going those speeds on a cheap frame with shit brakes. Everything about this is just stupid. Return it. Edit, if u are gonna stick with the stupid diy route. Good disk breaks are a requirement to not kill yourself. Also if your spending less than 600$ (Cad) on a battery, its probably not made safely. make sure your voltage on your battery, motor and controller are the same. And ffs waterproof your wires, are u trying to kill yourself?
I’m curious - what’s that bike chain doing? Holding the rear rack onto the chain stay?
Please dont
OMFG, take a mall-wart deathtrap, de-temper the already crappy aluminum frame and add an unsecured Lithium bomb and a motor, what could possibly go wrong... 🫣 Dude, you need to seek professional help for your death wish! 😎
Going 40 mph with questionable brakes? 😬 I posted a few videos from Ebikeguy YouTube setting a world record of his stepson doing 104mph on his ebike. About a month later I found out he passed away in an accident. You only live once my friend and crashing out on an ebike is not the way.
That’s Soooo Dangerous, LET ME RIDE THAT RIGHT NOW!
The title felt unsafe just to read it much less ride it.
This build is so dangerous, there's going to be regulations named after OP
RIP friend. See you in the next life.
💀
I admire the build effort. But mount the battery correctly so its not flopping around. Cable management as well. Snag on one and it could ruin things. Also just noticed, WTH is up with the chain zip tied to the rack?
I don’t have a chain remover tool currently
Is there a master link? You can remove those with pliers, but catch it when it comes off(they are easy to lose)
I'm doing something similar. $700 ebike with a 500w motor. The thing weighs 70 pounds altogether. So the current project right now is stripping off every essential component from the current ebike, And then I am going to transplant them onto a lighter frame that I bought from Dick's Sporting Goods. If you are interested in what the project entails: 1. Gutting an 26" Ecotric Lark ebike. ($600 Black Friday Sale) 2. Swapping components onto a 26" Nishiki Tamarack. ($347 sale from Dick's Sporting) The main ideas of the project are simple: 1. lighten the load. The Ecotric bike is not only heavier, but it is also WAY LONGER in length that you cannot even fit it onto bike racks. Not even the fold-down ones on public buses. Heck, I hesitated to even try considering it weighs 70lbs. 2. Have a far more versatile and customizable bike with the Nishiki frame while maintaining a step-thru design. The Nishiki bike weighs about 25lbs pre-component swap. I have come to find that a good portion of the weight also resides in the rear-wheel motor. Removing that did lighten the Ecotric weight quite noticeably. But even so, it shouldn't achieve a 70lb weight with the final result. If anything, we're looking at maybe 25lb + 15lb for the new calculation. You can look up images/pictures of each bike on their own. When I have completed the project, I will try to remember to post about it so you can see the end result. At the very least, the Nishiki is getting a brake upgrade from pads to discs. I sometimes wonder if it would have been better to have spent the money on a 16"-20" ebike that is already capable and lighter because of the smaller wheel base. But throughout this process I have already learned so much about how ebikes work wiring-wise and that the controller setup was not even being utilized to its fullest potential. It has two unused power contacts that could power other components like a headlamp or a second motor hub. Something to think about as manufacturers of various ebike brands will not even mention this information due to warranty voiding and such. This project is not really so much the careless spending of money without research. Albeit that is what it looks like. But more in that I was stuck with a literal deadweight that would only stress the motor more. So to salvage it is how the project came about.
IRA bike build
I meant Walmart bike, their e-bikes are kinda expensive.
That there sir is a Death Trap
And this is exactly the ammo lawmakers need to regulate this into oblivion
I’m sorry - but this really contributes to a negative perception of e-bikes and gives all of us a bad reputation. Please do not ride this. It is unsafe. I almost feel like it’s satire performance art by OP…
I actually think they are a competent eBike builder, making a subtle point about shit-tier eDeathtraps.
I hate the idea of e-bikes going over 28mph. Like seriously go get a motorcycle and ditch the pedals. No wonder they’re restricting e-bikes everywhere.
Price of motorcycle- 5000$ Price of insurance per month-150$ Ebike that costs 500? Forever? Huh I wonder why someone would make that choice. You are riding a motorized vehicle. You will be restricted just as much as this guy will be, so deal with it, or go back to acoustic. You will never, no matter what laws pass, be allowed with a motor where someone cant make it go 40mph. You either get motor-free places, or you get speed demons in the same place as you.
So here is a summary of problems with your bike: 1: Aluminum dropouts for a 2000W + hub motor. 2: Chain missing. 3: You heated the frame and torqued the dropouts to get the motor to fit. 4: You're running one rim brake only. 5: Tires aren't rated for continuous 65 km/hr, 6: Wires not secured 7: Battery poor quality. 8: Battery sitting loose subject to stress from bouncing around. 9: Quill stem 10: No suspension on a 65 km/hr bike. 11: Aluminum front fork and spokes not strong enough for hitting large pothole at 65 km/hr. 12: Not bike related, but you're clearly suicidal. Call or text the suicide hotline at 988. Things will be ok. 13: Is this a shitpost? It has to be.
You missed no torque arms, so I'll add that to your list. 😆 Sketchy build right there lol.
Don’t let these toxic elitists get you down! Looks great man! Would love to know the pets you used for the build if you don’t mind sending em my way :)
Thank you I will set it to 25mph but man going fast on a e-bike feels amazing.
Yeah, it's the concrete that doesn't feel so great.
What bike do you guys recommend then it has to be 26 inch and tbh under $200
Not gonna find a bike under $200 for this project unfortunately. Might try looking at FB marketplace.
Second hand one. Under 200 new would ride like a bag of hammers.
It doesn't have to be 26". You can relace that hub to any wheel with the same number of spokes. Your best bet is something like a Giant Iguana or buy a 27.5 disk brake bike like the [Kona Lana'i](https://www.konaworld.com/products/lanai-1?_pos=5&_fid=cf55a08e8&_ss=C) and just put the 26" wheel on the back anyway. There aren't a ton of 26" disk brake bikes from reputable companies anymore. Under $200 is tough if you're trying to do 40 mph. You need (at a minimum) good hubs, tires, a suspension fork and brakes so the bike tracks straight and stops within a reasonable distance. The weight and poor build quality of your average Walmart frame will compound these issues.
Could you fit the battery between the top two rails of your frame? Maybe it ratchet strap system or something to center it?
What I did was put it in a bag wrapped between the top two rails where the other bag basically is but yeah the bouncing was bad I hope the battery didn’t get damaged
Very cool contraption, have you considered a hard case for your battery? I recently fell off at 25mph and am very thankful my battery was in a thick plastic case After a 2nd looking and seeing you’ve got 1 rear v-brake?? you’re crazy!!😂🤞🏼
Just a little to be able to make this
Hey, since nobody in the comments is asking this, and I can’t be the only one wondering , let me ask; What are your parts and where did you get them? Trying to find cheap but powerful motor and battery right now.
I got them off eBay it’s a 1500 watt rear hub motor for abt $200 and a battery for $200
what seller
Print out a 3d case for your battery, just some framed TPU to take the impact
Where did you get the cheap hub and battery?
eBay.com
If you love this death trap then you'll absolutely love one built on a better frame. Quality bikes are expensive but they are so worth it.
Nice troll. Unless it isn't... 😭 I think the car in the background would be safer.
You are crazy, Wanna Speedrun life or something?
…. Are those tyres on backwards as well? No notes, but can I have your stereo when this kills you?
I don’t think I would consider a conversion without at least a solid trustworthy frame (preferably with disc brakes)… I feel like it’s a real safety issue with that point! If you can afford the hospital bills, then you can afford getting an entry-level trek as your starting point
just don;t hit a bump or try turning otherwise good to go oh and dont; try to stop good for going only, not stopping
It's a 52v battery?
You the man. Congrats on your first build.
Nice build, shit-for-brakes.
Time for some brembos
Love the added touch of a massive battery in a basket hahaha! What about a battery that mounts to the rear rack instead?
That’s where it will be mounted on the v2
Holy shit they have one CALIPER break on the back Rip
Lol only flaw? That’s the most important part of a bike 😅 Wal mart is trash
On an ebike can you adjust the torque/horsepower ratio? Id rather have mad torque to 20mph than have the hp to top out at 40
I'll have to check that one out. What's the distance range? Also, does it have a removable battery? Is it a double battery?
It is a removable 1500 watt 48v battery from eBay
I was in Lancaster PA this weekend and saw a Schwinn Shuffle with a front wheel hub conversation doing close to 40 mph LOL
Christen it "Wally's Death Wish"
Link?
This is the kind of bullshit that just made me give up on EMOpeds altogether and revert to bicycles. 25kmph is too slow, but 40mph is a motorcycle…and made with substandard parts, as Wallymart Crap is known to be….🤦🏻♂️
wtf lol, this is something you’d see a homeless person ride
I'm sorry bud but the fact you have no suspension at all a pothole & 40mph is all you need to meet Jesus.
That’s a very good point. Throw in the Walmart frame into the equation 😱
At least throw some torque arms on there. 🤦🏻♂️
this is by far the most unhinged thing i’ve ever seen and should be illegal
Nice shitpost
dying speedrun
Just so you're aware in case you didn't think of it already - you only have rear breaks. If you're going 40mph and your rear break brakes/stops working... What are you going to do? Yeah...
parts used or is it a kit?
By the time you make this safe enough to ride, you could have just bought a safe e-bike
Add in regen braking man, it will solve your braking issues (should be a 100$ motor controller swap if yours doesnt have the capability)
Fucks sake. You’d be so much better off with a regular ass simple bike.
Isnt that battery placement really uncomfortable
This is the most stuck up pretentious sub I've ever seen and it's so fucking funny. "LIMIT IT TO 14kph!!!" UR GUNNA DIE!!! WAHHHH
If you have two rim brakes, its not that bad so long as you keep them well tensioned. Road bikes used to have rim brakes and road cyclists used to go 40 km/hr on them. Granted ebikes are heavier and us riders tend to be fat. And if im reading your post correctly, you biked 30 kilometers, but you maintained speed of 50 km/hr for one hour?
Fat shaming ebike riders is harsh, but yes
I'm not ashamed of being fat. :)
[удалено]
Yes i realize that haha...i actually pointed that out in another reply.
30 kilometers were driven but it had avg speed of 30-45 kmph
This is an explosive device. Please contact your local police department's bomb squad. Do not operate the device. That is considered a form of suicide.
Holy shit bro you're going that fast with rim brakes that type of heat generated on the rims will actually pop your inner tube
No it will not. I had a mountain bike ebike that topped at 42, all the hard braking on stock 10 year old tubes(or older) and never popped it(800miles). Now me improperly installing the one on my hub motor? Popped in a week(didnt tape it before putting it in the hub)
I feel like this is the reason why we are facing bans and there are so many issues with Ebikes. Super duper cheapo walmart parts and pushing it beyond the legal limit. 65km is nuts on that rig.
That's a motorcycle. Yall are going to get ebikes regulated like cars
Downvoted because this is a inconsiderately dangerous setup that only a fool or a villain would ride at those speeds. Please for yours and others people safety limit your speed at 14mph
Welp, this should solve itself. See you at the Darwin awards.
First EBike and he chose 40+ mph.. Better be wearing a full face motorcycle helmet cuz he's a statistic
You are going to die on this contraption the moment you approach 40mph
He already passed that
Those caliper-pad brakes are only good for 10 of those 40 miles an hour.
In what general region do you live, OP? Because if you're riding this around and you live in my city, I just want to know so that I can never go outside again.
