To the guy who uploaded this video, thanks for uploading this video because I've been wanting to find the most simplest and cheapest way to convert a regular bicycle into an electric bicycle. I'm sure there's probably no simpler home made electric bicycle set up than in this video above. Since he put in the video about being able to drive for one hour per charge on the batteries, I would just only turn the electric motor on when I really needed it, like if I ride a bicycle long enough distance I'd turn it on when my legs got tired, or when riding a bit enough up hill. Then when I'd start coming to a bit steep enough down hill, I'd turn it on for a bit just to help get me up to a good speed and then when I'd get going down hill I'd turn it off. If a persons going to do anywhere over an hour of bike riding, to me that kind of home made electric bicycle set up is still good if you just conserve power by still pedaling as much as you can, and just letting down hills work for you instead of the motor when your going down hills.
I really like it. So simple and not so bulky. But I guess you have no control over the speed right? It's either on or off. Of course you have your brakes and you could manually turn the motor on and off. Good job :)
My friend, this is absolutely amazing. Everything on your channel is phenomenal! The information and capability we have at our fingertips today is...just...crazy. I find this kind of stuff fascinating and hope to learn the basics and start creating stuff like this! Take care.
Thank you for your reply. Do you note any loss of friction between the wooden wheel and the bike tire? or anything that you would improve on a 2.0 version ? thanks!
If you go over any large bumps could you damage the motor from the direct impact? Would it be safer for the motor if you attached it to a thick coil for shock absorption? Also wouldn't riding this in wet weather or on dirty surfaces damage or clog the system? I'd love some feedback as I plan on doing this! Being that I live in rainy and dirty Vancouver these are big concerns for me! Great video!
Neat BUT there are several problems. 1. The speed is too high. I would say 15mph is the maximum speed for comfortable safety on a pushbike, particularly given their appalling brakes. 2. It will wear out the back tyre too fast. 3. It causes rolling resistance meaning you can't freewheel much. To improve this, I'd recommend using a rear wheel on the front of the bike and putting a chain drive to the motor. That will mean freewheeling is easy. I'd also use a lower powered motor with the same battery in order to keep the speed down and give longer range. Full marks for the attempt. I'd like to see attempt 2.
Great job. A little polishing up as you feel like, but it works as it is. And it would get about 21 mph in my world. And about an hour on a charge? And those batteries are small and light enough that you could hang a couple more on the other side and either up your speed or double your range.
Firstly Thank-You! I have been wanting an E-bike for some time due to a leg partial disability, but they are very expensive. I am going to try to build one like your design. Thanks again!!
Thx for sharing, I imagine that by adding a second saddle bag & 2 more batteries you could double your run time between charges, a very simple concept. What about solar panels all over the exterior of the saddle bags charging the batteries while the bike is sitting inactive or traveling in the sunshine
I think it's better to mount motor on front wheel. This way you get propulsion on both wheels and you don't have to get off the bike to do some adjustments. Add spring loaded lever to easier connect or disconnect motor from the wheel, so motor wont slow you down when you just want to pedal by yourself (like generator on front wheel in 2:19). Still, great job. I'm planning to do this stuff myself.
Hey man that's a nice project! Is there anything else (diode?) in the circuit beside the batteries in series, switch and dc motor? Do the batteries still hold charge now after almost a year?
Yes. Simply add a second wheel between your motor and your bicycle wheel while driving down hill. That's the mechanical part. For the electric part: as you say, switch some diodes for not letting any electricity flowing into your generator/motor (back). It's known as generator circuit. Of course only pedaling will turn your trip into iron man like circumstances.
Wow! Awesome! Keep upgrading it, don't stop! I just want to ask: Perhaps it would be better to use it as a hyper-accelerator (fanaticism to Star Wars) when driving in high gears, isn't it? Sorry for my syntax, I speak English poorly :D
hola, hablás español? porqué no usaste una cadena y una corona o piñon como transmisión? de esta forma el rozamiento no implica mayor desgaste de la bateria y menor tracción? la probaste cuando llueve con la goma mojada? gracias!
I heard the new Rubbee (also from Europe) is about $1300 USD, and can only go for about 45 minutes on one charge. ...and it only gets 15 mph tops. Yours bets that hands down! Congratulations! Yours is definitely my type of thinking! Now, the Rubbee is really sharp looking and handy, but not nearly $1200.00 sharper and handier!
How did you wire it? Did you just connect the switch between the motor and the batteries? Also, did it not work well in the rain due to the circuit not being waterproof? Or was it due to the friction motor setup itself?
Did you have any issues with having everything in series? Do you think that would stress the motor since you can't limit the current going to the bike? What advantages do you have with the relay?
It's crude, but it seems to work very well. I would assume that alignment of the motor wheel with the cycle wheel is pretty critical. If only you can charge the batteries when the cycle is freewheeling, that would increase your range.
When I saw the motor turned by the wheel because of inertia or power from pedal, I remember about regenerative braking. Just switch the motor input (+) to (-) (just switch the poles), it will become generator (even it may cause damage).
FYI, 10Ah is a completely different measurement than 10A, in the same way that 10 light years is different than 10 years. A is current which is a flow rate, Ah is charge, which is a capacity.
Это одна из проблем, поскольку сама подвеска двигателя фиксирована, вторая вытекающая следом - изнашивание покрышки, колесо узкое, прижим не регулируется. Сырой стартап короче..
Looks like it has inspired someone (Rubbee). Very nice design, and I willing to make a clone of it on a PET Plastic Bottle Bike Frame. What material the wheel that touches the tire is made of? Thank you!
would adding a higher watt motor make you have a higher top speed or be able to move a heavier person? would a higher watt motor drain the battery faster? I'm about 180lbs looking for something to get me 3-5 miles to the local town near me. how well does it handle the stress of hills?
A motor is always a generator in the oposite direction. Try to drive while the rubber wheel touches the bicycle wheel so the battery pack should charge!
How do u ensure uniform traction b'n motor rubber disk and tire (bike wheels are not perfectly round)? What happens when disk-tire grip is compromised with mud? U don't mention controller, throttle, and freewheel (b'n motor &tire=>u have motor drag whenever motor shaft spins faster than e/m field alternates). So u can't control level of power assist, just On or Off at maximum?
interesting. my main concern with such a design is efficiency. have you done some calculations on how much power it uses at various speeds? also, I highly recommend lithium iron batteries. you can get some when the leads die out. maybe some A123 26650 cells or a string of headways.
how did you record yourself riding from 3rd person? or is it 2nd person, is that even a thing? anyway, well, how did you record yourself on the bike so we could see you riding
where did you get the on/off switch and wouldn't be better to control the speed with a controller instead of an on/off switch? Also how do you connect the motor to the batteries and how do you charge the batteries?
hi thanks for answering my questions I have some more; how did you mount the friction wheel to the shaft of the motor and where can I find a friction wheel like that one (from ebay?). Will a normal on/off switch work with this system? Furthermore, what cables/connectors you used to connect the two batteries in series and connect the pair of batteries to the motor and the power switch? Also how is it possible to use a 1.8 A charger to this type of batteries with two poles?
I get it, functionality over form, and its pretty cool but my god man did you use a hatchet to cut the metal? ... my other thought is you could setup a sort of deadman switch, so that when you apply the brakes it disengages the motor.
***** Hey bud the bike gen you have on the front tire put one more on the back and two DC rectifiers and voltage regulator that should be a self sustaining system
+Doityourself Gadgets Hi! I want to ask you one thing: I've figured out while the video was playing, that the electric motor is turned on/off by a switch. Then I've seen that while the motor is working a thought that maybe you need to brake hard in case of emergency. So, the motor maybe still running and so it may be damaged by counter forces of action-braking. Did you installed a kind of clutch or something to avoid this problem? Or the electric motor shall be turned on/off manually even in emergencies? Awaiting yours! By the way: really nice way to spend some time with your mind!
***** Thanks to you for the prompt reply! Actually, maybe a disconnector could be useful for this purpose and moreover can be added to improve the life of the motor and of the wheel. Do you already thought how to fix it?
Any way to make the regular pedaling power the battery? Maybe you could use the same principle of a wind up flashlight, but on a larger, more efficient, and more useful scale.
You can make a bike that charges batteries via petal power and inertia, you can charge a battery on an e-bike. This is not a bad idea, however based off friction ... that is a little different.
Hello! I have a few questions, please answer: how did you ''tie'' the motor on the bike, how did you connect the motor with the on/off switch, how can I find an on/off switch, where can I find a wooden part to put on the motor like you and would I use motor batteries 12v, 12 ah, or what batteries??? Thanks and please answer my questions.
Simple, Just simple!, no microprocessor, no computer, no problems!. Keep rolling and working on future projects!

Реализовано не очень аккуратно, но за идею, спасибо! Удачи.
Thank you for your reply. Do you note any loss of friction between the wooden wheel and the bike tire? or anything that you would improve on a 2.0 version ? thanks!
Very cool, nice design. How many miles can you do on a single charge just using the motor? Does this set-up wear out the tyre faster?
If you go over any large bumps could you damage the motor from the direct impact? Would it be safer for the motor if you attached it to a thick coil for shock absorption? Also wouldn't riding this in wet weather or on dirty surfaces damage or clog the system? I'd love some feedback as I plan on doing this!

You do realize that 35KPH is only about 21MPH
Starfire Technology yes, i do. I also realise that on uneven pavement and near pedestrians, 10mph is more practical and 15 is the upper safety limit
Then you either have no idea how slow 15MPH is or you only ever ridden a bike with shit worn out brakes. 15MPH is a fat man running.
how well does it work when the tire is wet? does the loss of traction affect the efficency
OMG its amazing.......well done mate.....I admire your creativity .....
welcome
nice! does the engine "eat" the rubber of the tyre?
Very simple and tidy, I have the bits from Ebay so will be putting it together at the weekend. Thanks for posting videos that inspire others.
is possible to create a switch to modulate the speed? Greta work =)
I would really like to build this but I am having trouble with one thing. How did you build and attach the throttle to the engine! Great video
Great job. A little polishing up as you feel like, but it works as it is. And it would get about 21 mph in my world. And about an hour on a charge? And those batteries are small and light enough that you could hang a couple more on the other side and either up your speed or double your range.

How does the braking work? or would you have to turn it off and then use the breaks on the handles?
Simple and effective, well done. How did you get the wooden wheel to stay on the motor shaft ?
One of your best projects! Thanks for the videos, your channel is really interesting!
adversely would peddling the bike generate current to recharge the batteries?

Enjoyed your vid. Liked the wood. Are they golf cart 'type'traction batteries? Cheers.
The question which bugs me, how about rain? wouldn't the friction between the motor and the tire be influenced if it is wet?
What exactly is the rubber drive wheel attached to the motor? Where did you source that or did you make it yourself?
What kind of motor to search for that has the same drive on the front of the motor? Or did you fabricate the drive yourself?

Yours is definitely my type of thinking! Now, the Rubbee is really sharp looking and handy, but not nearly $1200.00 sharper and handier!
ok is there a speed controler or just on off one speed?
Friction drive or coupling. Simple, yet effective when done right. Nice, good job.
very nice job! What rpm range is that motor? And are deep cycle accu's preferable or just regular car accu's?
Antonio Valencia doesn't need this bike..,he is one!!
How did you wire it? Did you just connect the switch between the motor and the batteries? Also, did it not work well in the rain due to the circuit not being waterproof? Or was it due to the friction motor setup itself?

+Doityourself Gadgets should I add all weather grip to the wheel so it wouldn't slip?
Hi which part is there on the motor that is rotating the tire
So what ESC are you using? And does the ESC have built in breaking?
u could use a 12 v car battery charger, 2x 12 v parallel loading. "in Reihe geschaltet" (german) then you have 24 v. Thanks for the vid.
It's crude, but it seems to work very well. I would assume that alignment of the motor wheel with the cycle wheel is pretty critical. If only you can charge the batteries when the cycle is freewheeling, that would increase your range.
Could you hook up a variable switch to the motor instead of using an off/on to get a level of control over the speed?
I want to use my everlast welder to convert my bike to electric. Thank you for the ideas.
Looks like you used a can opener to modify the fender, am I right?
Can you recharge the batteries by pedaling?
How loud is the motor?
Does motor still running if you have to break in case of emercency or you have some sort of system of protection?
I'm unclear about series circuits. Would adding a third and fourth batter in series just further extend how long it lasts?
*****
Then wouldn't it be better to do parallel because it would extend runtime?
What do you use for the motor to touch the wheel?
good idea, you can hide it and its good enough for most purposes
what kind of motor to used?
isn't it hard to balance when 1 side is heavier than another??
Can be possible generate energy for save him into the batteries during the pedaling?
to what point? It takes even more power to pedal wit the motor on. it would be better to disengage the motor when not in use.
no it doesnt make much diffrence get your facts right ffs
that's why i said a on off switch to generate use it to brake and down hill or if you have a stiff tail wind
also a home generator for the months riding outdoors is bad weather
If u pedal without the motor will it charge the battery if not u should implement a system like that
a bit of info please:
1. where did you get that wooden wheel?
2. when you bought the motor, what did you do to attach it to the wheel?
how long time the motor working and what about the motors hot
When I saw the motor turned by the wheel because of inertia or power from pedal, I remember about regenerative braking. Just switch the motor input (+) to (-) (just switch the poles), it will become generator (even it may cause damage).

Хорошая идея. Но при работе педалей, движок тормозит.
***** good idea, but the motor slows you down if you are pedalling when it's off
YuMiPo0N Как то так.
Сергей Александрович when motor is off, it`s charge the battery (recuperation)
+YuMiPo0N It lifts off the wheel like a clutch.

just add some magnets on the spokes and a two copper plates attached to the frames and there you go :) you can even make it on the two wheels :)
what did you use for the wheel on the motor? :)
Great video.
Why don't you mount the battery pack inside the frame between the front and rear wheels, it will give you a lower centre of gravity.

maybe some A123 26650 cells or a string of headways.
Very good project..I will try it.Can you tell me the description of these batteries? I mean what Amper and Ah they have
thank you
You can charge battery when driving downhill
I noticed that you do not have a controller is this normal?
If I built another electric bicycle I'd defenitely include a controller, braking system and use electric hub motors!
Nice one but it will heat up and even increase wear and tear of the tyre
That's true. Airflow from driving was cooling the motor, though. Nowadays I'd recommend using a hubmotor!
How is it going to climb?
It was not a very good climber but the power was enough for normal hills!
Complimenti, prendero' spunto dal tuo progetto!
