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.
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.
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?
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
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.
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.
i love all the manufacturing of the brackets just to mount it on a 30 dollar 50 year old worn out aluminum frame, and then have hella loose clothing by the drive train haha. *not to in any way lesson your build. You got er done and made a video about it! Thank you for posting this you mad lad!!
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.
@@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.
@@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 :)
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! Next, make it liftable from the wheel, so you're not turning the motor when you're pedaling. And make it a generator when you're going down a hill, so it charges your battery :)
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.
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
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.
The only problem I see in this build is that it's rather non-adjustable. If ridden enough, eventually, you'll have to replace that back tire. You're just gonna have to cross your fingers and hope that the new tire's dimensions exactly match the old one. Great build just the same mate.
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

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.
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.
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!
Best thing I did recently was sell my big heavy ebike for an expensive normal bike. I struggled a bit the first week as felt like riding in syrup. Now I'm in love with cycling again. Fun holiday but ultimately don't need an ebike and am healthier and happier on a human powered bike.
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...

I'm thinking about doing something like that but with a spring loaded mechanism to lower the hoverboard wheel and make contact only when I need to, to avoid the extra drag in normal bicycle mode. Nice work!
The spring loaded setup wouldnt add that much cost to the project, you can probably add a small brake cable to adjust the tension on the wheel. I built something like that way back for my gas scooter with a trimmer motor. Fire it up out of contact, then lower the engine onto the rear wheel while in motion. This wheel-wheel contact will suffer in wet applications where you will slip between the wheels, thats where some pedal assist will come in handy before you are coasting.
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.
I love these videos where they advertise hpw cheap it is to diy something and then the whole video is them in a workshop with thousands of dollars of tools and equipment 😂
U can do the same thing with just 2 bits of roughly guesing 40x40 timber screwrd to each other on the back and front frame with a wheel hole pushing the motorised wheels down.
I love the ingenuity of this conversation kit build however considering the various power tools needed, if you account for the cost of those and the cheap parts for this particular conversion kit, it’s not exactly cheap
That is true, but you can make a bracket relatively cheap using angle aluminum and bolts. You can get this build off the ground with a power drill and a metal blade saw. That being said, there are some very cheap ebikes out there, I recently bought a jetson bolt pro for $220, cant beat that for a fully built e bike, batteries, etc. If you add the controller in here, time, the bike, you can probably get a used ebike for a lot less work.
That’s actually one of the projects I have planned. I’ve got a relatively big electric plane motor from work, and I’m gonna put it in a kayak or canoe or something. Whatever I can pick up from Craigslist on the cheap.
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
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?
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.
Maybe you could put a second one as the center of the back wheel, when the top one finally accelerates you so the center motor doesn't stall, you can get a higher top speed
I remember seeing a different channel do this, it is actually a better idea but you have to redesign the hoverboard motor to have two sides coming out of it and also you need to get rid of the bearing that's usually there, shorten the length of the metal wires thingys going to the middle and if you can do all that, you will have a better more efficient motor!
would have been a killer vid if you used nuts and bolts instead of welder, most average people have the skill level for this build and ability to source parts, but the welder is out of reach of 95% of people
Flux core welder goes for $100 from harbor freight. I've had it for about 3 years. I've probably only put no more than 50 hours of use on it though. I just finished copying this project and putting it on my gas motorized bike to make it a hybrid. I made the adapter for my bike using this welder. Overall there isn't a lot of traction between the hoverboard wheel and the bike wheel so there is A LOT of slipping. I'm currently trying to figure out a way to push the motor into the wheel probably using a spring. The welder worked great for my go kart build, workbench and other projects. Obviously if you're going pro in this area don't get any tools from harbor freight apart from their zip ties which are a real steal.
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..
Slide too far back on that seat, and Wipe Out! in every sense of the term. But seriously make it spring adjustable and you can sell the kit, or at least the basic part some of us don't have the equipment to build. Great idea, I had no Idea it would move that fast. Will it take off from a standstill with no peddling?
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?
@@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.
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 ?

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 ! 👍🏻😂
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.

I'm thinking about doing something like that but with a spring loaded mechanism to lower the hoverboard wheel and make contact only when I need to, to avoid the extra drag in normal bicycle mode. Nice work!
Sim , e a mola vai dar mais tração para o motor não patinar.
The spring loaded setup wouldnt add that much cost to the project, you can probably add a small brake cable to adjust the tension on the wheel. I built something like that way back for my gas scooter with a trimmer motor. Fire it up out of contact, then lower the engine onto the rear wheel while in motion. This wheel-wheel contact will suffer in wet applications where you will slip between the wheels, thats where some pedal assist will come in handy before you are coasting.

Nice conversion!
Allsome work guys from cruzermans inventions 😄👍🥳😸
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.
@@oneeyedrone4293 Isn't this controller already doing that? 40v x 18a = 720 watt. That is, if the controller info is true.
Yeah, looks pretty easy alright, IF you have the top machinery/tools, that is. Which most of us do not..
Now put one on the front too :)
One Smart Man :) Thumbs Up to you
Your video inspired me broo,
Thank's for the content 👍
Tweaker craftsmanship at its finest.
Awesome BUT we don't have a shop like yours. You should built the bases and sell them. Then we can buy the hoverboard board and built it!!
This is brilliant, but not everyone have your tools, not a easy conversion for most people 😊
Need kit for majority
I love these videos where they advertise hpw cheap it is to diy something and then the whole video is them in a workshop with thousands of dollars of tools and equipment 😂
U can do the same thing with just 2 bits of roughly guesing 40x40 timber screwrd to each other on the back and front frame with a wheel hole pushing the motorised wheels down.
I love the ingenuity of this conversation kit build however considering the various power tools needed, if you account for the cost of those and the cheap parts for this particular conversion kit, it’s not exactly cheap
If you dont have tools you can not build anything
That is true, but you can make a bracket relatively cheap using angle aluminum and bolts. You can get this build off the ground with a power drill and a metal blade saw.
That being said, there are some very cheap ebikes out there, I recently bought a jetson bolt pro for $220, cant beat that for a fully built e bike, batteries, etc.
If you add the controller in here, time, the bike, you can probably get a used ebike for a lot less work.
Solex mopeds used to be popular...they had a drivewheel on the tire driven by a gas engine.
It's easier and more effective if you put spokes to the wheel doing some drills. 😊
I guess it's that easy when u have a whole machine shop at your house lmao😅
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
You need gearing or at least a planetary gear setup or initial take off load could burn up the motor. Could work if in motion when activated.
Could you make a kayak "outboard" electric motor or use a big RC motor with a long shaft and a propeller at the end? That would be kinda cool
That’s actually one of the projects I have planned. I’ve got a relatively big electric plane motor from work, and I’m gonna put it in a kayak or canoe or something. Whatever I can pick up from Craigslist on the cheap.
Not with a hoverboard motor, not enough power
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
Cool idea I wonder if you could reduce the terrible noise it makes with a smooth street tire on the back
Hi, I envy with your skill and equipment which I do not have but Ị have same passion. LoL
EASY CONVERSION FOR WHO JESUS UNDERSTATMENT OF THE CENTURY.
Fantastic idea, but please put a cover over that drive wheel!
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?
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.
EV Innovation Love it ❤
Best idea best video for ever!
If you get a flat there goes the electrical aspect of it all. But nice work! - Scooter Doctor
Nice job. How many miles do you get on a full battery charge?
Very easy. You just need a fully equipped metal workshop with welding equipment. 😅
Maybe you could put a second one as the center of the back wheel, when the top one finally accelerates you so the center motor doesn't stall, you can get a higher top speed
I remember seeing a different channel do this, it is actually a better idea but you have to redesign the hoverboard motor to have two sides coming out of it and also you need to get rid of the bearing that's usually there, shorten the length of the metal wires thingys going to the middle and if you can do all that, you will have a better more efficient motor!
Класс! Надо бы сделать чтобы колесо отстёгивать с верху если аккумулятор разрядиться и на педалях ехать будет легко.
Good job 👏 👍 👌
would have been a killer vid if you used nuts and bolts instead of welder, most average people have the skill level for this build and ability to source parts, but the welder is out of reach of 95% of people
Flux core welder goes for $100 from harbor freight. I've had it for about 3 years. I've probably only put no more than 50 hours of use on it though. I just finished copying this project and putting it on my gas motorized bike to make it a hybrid. I made the adapter for my bike using this welder. Overall there isn't a lot of traction between the hoverboard wheel and the bike wheel so there is A LOT of slipping. I'm currently trying to figure out a way to push the motor into the wheel probably using a spring. The welder worked great for my go kart build, workbench and other projects. Obviously if you're going pro in this area don't get any tools from harbor freight apart from their zip ties which are a real steal.
Great engineering
Een electrische Solex, maar eenvoudiger aan de voorkant. En natuurlijk een loskoppeling nodig.
U MAKE A MEAN ARTICLE JUST THE ONE I WANTED TO MAKE
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..
Slide too far back on that seat, and Wipe Out! in every sense of the term.
But seriously make it spring adjustable and you can sell the kit, or at least the basic part some of us don't have the equipment to build. Great idea, I had no Idea it would move that fast. Will it take off from a standstill with no peddling?
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 ?
BRAVO ! FROM RUSSIA!
good idea i will try this!
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 ?
Nicely done
❤ 👍 clean install ❤
Very good, you're expert.
How to recharge the battery?
I just plug it in directly in the hoverboard charger
its amazing ..... but i want you to drive it on a muddy terrain or rainy season
Fantastic idea
