- In this video you see me converting a bike to electric ebike with hoverboard parts. I wanted to make one as cheap and easy as possible. I do some welding but if you don't own a welder you could probably bolt something similar together with basic tools.
The total cost of this ebike conversion was only 64,29 EUR / 72,78 USD.
Motor and battery are from a second hand broken hoverboard (can be sourced through local second hand sites). The controller and frame bag I bought on Aliexpress (links are below). The bicycle was already in my possession.
The range (without pedalling) on that small hoverboard battery is approximately 5km (3,11 miles). That is not a lot but can be easily increased by pedalling and/or adding more batteries.
The maximum speed without pedalling is 27km/h (16,8mph). It actually drives very well and I am happy with the result.
Specs:
Battery: 36v 4.4ah
Motor: 36v 350w brushless
BLDC controller link: nl.aliexpress.com/item/400014...

Thanks for watching! Let me know what you think in the comments below ;)
Originally, the motor is wired in Star configuration. If you rewire it from star to delta, the motor will spin from the original 700 rpm to even 1200 rpm ! That means you'll gain a lot more speed.

Lets assume you don't live in a very dry country and the drive wheel and tire get wet.
Lets say you're Skimming to work and you tyre goes through a splash of oil of another car and you're 7 hours late to work due to drive slippage?
A Design that needs some Design.
Man I have been waiting for someone to build a friction drive with one of those.
Can I order this for my son
Now time to add a front motor for all wheel drive e bike :) Those hover board motors make great donors since they can be purchased for so cheap.
I always thought electric vehicles are to quiet and dangerous but with your brilliant genius you have solved the problem ! 👍🏻😂
...ELECTRIC motorcycle 🏍 etc are bad news ..,,WIND FARMs are Weapons of Mass destruction WMD and causing WEATHER WARFARE putting ELECTRICITY into the Atmosphere and flatearth101 is real and Canada and USA are Corporations of Rome btw and government means MIND CONTROL so Stop VOTING and
I love your videos. Very creative. Keep up the good work.
Very cool project. Inspiring me to do something similar.
Great subject. I think you need to add a splashback above the wheel (to avoid water splashing against your coat and to avoid something above it can hit the wheel) and a spring/tension system that follows the surface of the wheel. The spring/tension system could also you enable to temprorarily disable the wheel (take off in pause position). This idea is actually something like a Berini (1949) or Solex (1946) with a clip-on motor/engine.
Loved this project and Just what I was thinking. Yes put the motor on a hinge andI a gear-lever like a handbrake in a car to disable it
Good thing about this idea is that it is completely reversible and the bike doesn't have to be altered. More manufacturers should be providing solutions like this.
you should be able to done this using arduino, motor driver, and reverse the enable pin, but i don't know in 3 phase motor, should be the same principal and should be able
But why you need reverse in bicycle?
@@yoyatech he means that he can reverse the process and remove the pieces. Not going reverse on a bicycle
@@alfredo-ff ah, sorry
i'll tell you guys if i made one
Better . Where can you buy precut kit ?
What watt size are the motors I have two smart st zing hover boards what range will the battery give and speed please I now you could have a bigger amp battery but this looks ideal for a trip around a town and light if added to a cheap fold up bike to carry in a camper van
Best part, non destructive solution. Worst part, needs an anti-"Isadora Duncan" shield. I like the attention to neat minimalist construction. A lot of videos have rusty half-assery and motors that won't run very long before they fail.
Thanks for the info along with the parts. Saves me time.
Thanks for sharing, i'll try to upgrade this project to be able withstand light rain
You have a great imagination my friend. Carry on doing what you do best!
@3:10 Butta' Finga's!! 😁 You are an AWESOME Craftsman!!🙂
I built this over the summer for my kids. I didn't know someone else was building the same thing. I like your design better because it's more adjustable. Btw, the motor can handle 500w.
'
make sure you add a guard. wouldn't want to see what happens to any lose clothing or whatever is attached that goes between those two wheels.

Pretty sure these will take about 1500 watts if you bring the volts up;)
@@0xsergy good thinking mate!
WHY NOT USE BOTH MOTORS?????
No long coat tails!
Nice job, I nearly have all the parts to do this to my old bike!
Wow! Now that’s one cool electric motor cycle.👍
Very professional work, Thanks my friend, Big liked
Your jacket hanging above the rotating engine shold make you nervous. I think that's too close without a cover.
I only came here to comment the same 😂
Where’s it gonna go? At least six inches in circumference to reach the pinch point.

Debieras probar instalarlo atrás de la llanta trasera ya que tienes buen equipo, hasta te protegería del agua que salpica ésta. Suerte

Your video inspired me broo,
Thank's for the content 👍
Nice conversion!
What a totally interesting and unique build! It kind of reminds me of the old tire driven bike lights we had back in the day. It sat on the fork or tail and was a spring loaded device you could move out of the way in the daytime. But then flip it onto the wheel at night. And it was just a textured small metal wheel, that used the spin of the tire to spin itself as it rubbed on it and generated power to the generator it was attached to on your fork or tail. No batteries, just pedal/tire powered.
I had my doubts about how fast it would go, or how well it would work, based on when you fired it up in the shop, upside down. It looked like there might be a loss of traction between the two wheels. But I see how your logic worked there. Once it's upright and your weight is on it, there's going to be flex in the frame and it will make the two meet perfectly. Good thinking, because had you mounted it closer, there might be too much contact and friction/resistance and reverse torque.
Once you were riding it, you could see there was absolutely no loss of friction between the two wheels and perfect contact and minimal over friction and reverse torque. Just enough to drive the wheel forward solidly and it looked like any other front or rear hub or mid drive ebike. Bravo! So easy to replace too now that the bracket is built.
Dynamos arent old they are still a thing. mostly in hub dynamos tho
@@hillppari Yeah, I just saw the old school light dynamo devices still being sold. I guess with the resurgence in vintage stuff, including vintage bikes, they saw a market for some nice chrome classic styled bike lights, driven the classic way. They are mighty sharp looking too, very much suitable for a 1950's/'60s themed bike and is styled after the old school car headlights.
What is “reverse friction”?
@@thechumpsbeendumped.7797 Reverse torque (or friction) happens in all electric motors. It's a side effect of spinning against something and seperate from regular friction, but related. Like even the parts of the motor and fighting against itself, not necessarily an external force (although it happens with or without load). Bearings, for all that they smooth friction and movement, cause a slight resistance of their own in the motor. The shaft and the brushes rubbing against the commutator etc. That's back torque, or reverse friction/torque. The magnets in the motor also contribute to it. Additional force, against the motor basically, that friction from elsewhere cannot fully account/isn't responsble for. Slight usually, but they all add up.
The idea for generators which eliminate this, is highly sought after for generators that can generate more power than you put in. The quest for perpetual motion machines, we've been chasing for centuries, that's what it's related to. Mind you, not really full perpetual motion, we've given up on that, but close to it, getting way energy out than you put in, no losses=super efficiency. And it looks like India, not long ago, created the first generator/motor, that is so smooth, it's frictionless and eliminates all back torque too (back torque was the final hurdle). The ultimate in efficiency. So reverse torque is a problem, as you can see, in that kind of situation. It's just not one you hear mentioned a lot, because unless you are creating the most efficient motor ever made, we just apply more power to the motor and power past it. It is frequently an ignored metric, except in situations of extreme efficiency.
It's most noticed and an issue when dealing with efficiency. The most efficient motor (like what India just invented), would be one with no losses, one which eliminates this hurdle and apparently, they have. It would literally have to be the smoothest motor on earth really.
@@hillppari In the UK Dynamos are banned i think because they dont work when the bike is stopped at traffic lights or junctions...but they were clever little devices when i was young :)
Fantastic idea
That is a decent speed!
Especially when hoverboard motors are normally very slow.
they are very powerful motors, usually dual 350W, they just reduce the speed so people dont get killed on them. You can over run them quite a bit without damage, most can handle 500W punch and then coast at 350W.
Yes i've seen something like this idea on youtube on ebike review the one I saw has a small motor compact handcarry detachable with Battery all in one piece and actually this idea was already a vintage technology I saw a video of a Gas motorcycle with an incorporate motor drive attached on the back frame close to the wheel similar to that hover board position, but the drawback would be scraping your exterior same as this one
Leuk ding zo Hendrik!
En je werkplaats is gigantisch opgeknapt zo👌🏻 logo op de muur, netjes👌🏻
De todos los videos que vi, éste es el más práctico, gracias por tu video, haré exactamente lo mismo. Saludos . ( Like y me suscribí )
I order the BLDC and Bag My friend has a hoverboard ,the only thing i will be missing is the Arm that you build for the Hoverboard wheel , that goes behind the rear tire ...but im building it! inspire on your tutorial...thanks a lot...
Nicely done
Super nice, thanks for sharing, I'm building one. Cheers.
did it go well?
@@rocco-s-107 yes, but it was stolen.
Intresting video!
nice , I say if the air was let out of the rear tyre while the motor was being fitted it would of helped , nice build , cheers.
Great engineering
I was wondering if you could help me determine a hoverboard's motor's sensor wires in correlation with the controller I have?
Does it charge the battery when you pedal or coast?
Would it be easy to replace that hover board wheel with a sprocket/gear?
this is acctualy really smart
I plan on doing that , but with a motor on the front wheel too . Build a pack to put on frame 😊
Good idea.!!! Thanks.!!! 😉👍
Very good, you're expert.
good idea i will try this!
Brilliant, nuff said.
I thought about doing something like this with hoverboard parts. I might do it now.
Nicely done...
Now put a small ICE on it and make it a hybrid that recharges the battery using the same friction wheel as a generator while under gas power effectively giving you an almost infinite range
Cool video...I would like to add this to my existing diy electric bicycle to get more speed ? I have a brushed motor with chain mounted on the rear tire...could I use my old Segway brushless wheel motor on the front wheel of my bicycle ?
Best idea best video for ever!
Very cool!
I built the same last year with a 350w hoverboard motor, but forget the hoverboard batteries that only has 4400 mAh at most, and low discharge capacity cells (few km and power!), and the friction is much better on a city tire. but the most important thing is the controller 36-48v, how many amps it provides because the formula is 36v X number Amps (let's say 20 amps) = 720w at peak (it can be easily handled by a 350w motor), so choose the right one!
Great concept,now next to try it on a fat bike .,stay safe
Solex mopeds used to be popular...they had a drivewheel on the tire driven by a gas engine.
would be interesting to know how many miles to the charge you get
Solid and simple! I wonder how many amps and volts these hoverboard motors can take I'm going to say around 20a at 52v around 1000w or drill some holes in it and add cooling fluid to the magnets and it might be able to handle 2-3KW.
Такую мощность с таким током длительно не может выдавать это колесо. Сгорит.
Goo job,at the moment,I am making an electric bike,I am using an overboard too
Greetings from Buenos Aires
Nice job. How many miles do you get on a full battery charge?
That was amazing. I road past a broken down scooter the other night getting off work, and was too tired to take it home and try that move. LOL I wish i would have seen this clip first but i,ll run across another one, and I would have tried it to make it with wood being the black Mygyever that i am I mite have pulled it off (probably only temporarily or need to be serviced regularly). GOOD JOB. I,m impressed.
amazing ,only how did you made the wiring from the hoverboard at 9:54 wheel longer
I build same idea 😃 I have on my channel I have build so many models of those different motors. Of friction drives its cool I like it
Good job 👏 👍 👌
Cool idea I wonder if you could reduce the terrible noise it makes with a smooth street tire on the back
is everything included in the hover board besides the handle bar?
Good idea 👍
❤ 👍 clean install ❤
You need a mudguard to prevent water splashing up when it rains. But good job. Well done. 👊👊👍🤟
You get more splashing down the back of your legs tbh
Does it damage the controller when you try to turn the motor manually?
One Smart Man :) Thumbs Up to you
Brilliant.
Is it better if you have the option to lift the small wheel so that when the battery is low you can use the bike normally
Wonderful
EV Innovation Love it ❤
Todo muy bello y la ventilación para el controlador, al final también se ve q le falta protección a la rueda de impulso, ya que su ropa queda muy cerca de ella y punto extra, por la tracción entre ruedas no desgasta prematuramente al neumático de la bicicleta? Gracias.
So how long does the rear Tyre last like this ?, and do you have to adjust it down as the Tyre wears or do you have it pressing down more into the Tyre?, also I would put a guard over it because it's a terrible nip point just waiting to happen 👀, but great idea nonetheless if the Tyre and motor lasts ok 👍
A mi esta idea...me parece la mejor por ser la más fácil de instalar...pero no solo por eso..sino que creo que este sistema es mejor para la ascensión en subidas...que es cuando más necesaria es la ayuda..
Just got done building something like this. I used a spring to pull it down. It... moves. I guess. The lack of friction is a huge bottleneck. I got some snow on my tire and now it slips so bad it's almost useless. And it's -13 C out right now so... that won't be going away any time soon.
I hate this city's weather.
that's a shame
What are the cable's that conect the accu and the howerbord
Hello my friend, I'm from Brazil, I liked this project of your electric bicycle very good, would you be able to provide me with the measurements that you used to manufacture the support that you made to hold the motor?
Thanks! Henny
could you give this braket sketch open?
Super ,good , work:))
Great job mate, just hope it doesn't rain as your rear is going to get pritty wet.
amazing!!
Hello, hope you don't mind me asking, but can you pedal without the motor being on too? I am trying to understand if it allows the motor to help only when needed, or if its needed all the time. Thanks!
Yes you could but it's a little bit heavier than normal because you have to drag the motor along.
My wheel I took of hover board has green green connectors on ..is both wheels motors or the one battery side
greatness
Nice job! A few thoughts/questions:
1 - Hoverboards usually have two motors... would that make sense here? The design would get more complex, but I wonder if we'd get more speed or if it would need synchronization as they might not necessarily run at the same speed? Probably not more range as that's more dependent on battery capacity than anything else.
2 - Have you looked at using the hoverboard controller board itself instead of a separate one? I've seen a few hacks to use arduinos... I might go that path... any tips?
3 - Would having a spring applying constant pressure be preferred than a fixed position? Not sure if that would be worse or better for the grip.
This is what I was imagining for the spring mechanism: czcams.com/video/guvFqb4zgBg/video.html
These guys used gas spring, which is even nicer.
1 - Two motors would double the torque but not the speed. The complexity and the (slightly) reduced range (assuming that 2 motors would be limited to half the wattage of the single one) would not be suitable for street use. Maybe only for very powerful motors or offroad use.
2 - Probably the original controller wouldn't survive 48V battery and so you would get less watt output (maybe too low to be used as ebike motor but i don't know).
3 - Not my competence area, sorry!
Awesome !
Thanks
How much is it going to cost for the battery to run it tho and also does it come with a charger ?
I wasn't going to sub to any more channels, because I have so many. I couldn't resist one more. You're Welcome. 😃
What will u need ?, How much will it cost to do as u did and or can u do the same but cheaper? And how long does the battery last or how long will it last per ride?
Great video! Love how simple this is with just a hoverboard. What would you say the major downsides of this design are? Ive seen people talking about tire slip, and the exposed wheel. Are there other issues that youve encountered?
Not really. Only when it is wet, the motor has almost no grip at all. Apart from that no complaints😏
@@hennybutabivery cool. I wonder what would happen if you had a mountain bike tire with really large treads, and then 3d printed out a tire for the hoverboard with flexible filament that had an interlocking tread that matched the bikes. Ive seen some pretty tough 3d tires, but still i wonder if they would just get shredded or what would happen when they arent perfectly aligned.
@@HavokBWR too much friction in such a system i think, plus getting 3d printd things that narrow would make their strength diminish. tread blocks have a fairly narrow spacing, the tire he has on there is a pretty "mountainy" tire.
Noisy
@@HavokBWR That's a big piece to print. Have you printed flexible filament ?
I wonder if you could somehow mount a cog on the motor and run it directly to the rear bike cassette. Might get more power output with no slipping
Found a hoverboard on side of road today and been thinking what to do with it. I might try your idea it's brilliant
Allsome work guys from cruzermans inventions 😄👍🥳😸
Класс!
Плюс такого устройства- этотуниверсальность без каких либо изменений в конструкции велосипеда. Минус- в дождь, естественно ездить не будешь, но после дождя, по лужам? Как будет зацеп с мокрыми колесами, ну и брызги будут просто фонтаном во все стороны.
Но в любом случае, автору огромный ЛАЙК!
Hi. I'm thinking to use the axle of the escooter wheel to be assembled in the left pedal axle and the other pedsl still has gears. Would that be possible to put together? Of course, locking the outer diameter of the escooter wheel would be necessary for it to work
That will not work because the wires are ran through the axle. So if you lock te outside, the axle will spin and will wind up the wires. Good luck with your build!
Hello I also made the same modification to the bike with the hoverboard wheel of 350w at 36v but the maximum speed is 20km/h. Did you also change the winding in the motor from star to delta?
I dont know, i did not change anything. I know some hoverboards are more powerful than others
Man u r amazing.
Cool. That's by far the best of the friction drive systems, excepting for maybe a quick release. It's the only system that provides adequate gearing for a hill and for the motor to run cool. You might run 72 volt for 40mph without issue. Also the simplicity of drive train is excellent and looks durable as hell.
Q's?
Did your electronics get hot in the bag?
What's spec motor / battery would you pick if you could pick anything?
I tried friction drive and its not that good. Burns your tire when uphill and works veeery bad after rain. Now i wanna try with chain. I put 44 teeth gear on rear wheel and need to find out some small sprocket on the motor. It might work with ratio 44 to ~10. Will see
@@bobikbobikowy5458 Yep - be sure to get the right shaft size as well as the chain size. They have them on eBay for around $10.
You could made it with a spring, that loosing profil or eggs in Tire will be compensated. So it's tight till something happens on back tire.
Tweaker craftsmanship at its finest.
thanks
Hi, I envy with your skill and equipment which I do not have but Ị have same passion. LoL
How much range can you get from that seemingly small battery ?
Have build on like yours. but think speed was to lov at 36V so i went with a 72V battery. how fast do you go with a 36V battery?
Topspeed is 27km/h on 36v. I still have to test it on 48v, however on 36v it's fast enough for me😏
great job 👏 so cheap and simple but so effective 👍😎 what type of a battery you’re using? how long can you drive with this battery? thx 👋
Hello, all that info is in the video description😏
