Simple, Just simple!, no microprocessor, no computer, no problems!. Keep rolling and working on future projects!
Greetings from Buenos Aires!
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 see that you get quite a bit of criticism but I think you've done a great job.
@@STOP_RIGHT_THERE_CRIMINAL_SCUM this comment is a bit old but you are so god damn stupid, it literally says in text in the video that it came from eBay and it's a scooter motor...
go fuck yourself asshole
Реализовано не очень аккуратно, но за идею, спасибо! Удачи.
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 :)
someone give this guy an award
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.
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!
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.
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!!
Du bist der wahre Bastler !
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.
One of your best projects! Thanks for the videos, your channel is really interesting!
OMG its amazing.......well done mate.....I admire your creativity .....
welcome
Love the simplicity!
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
nice job,simple and working fine
Complimenti, prendero' spunto dal tuo progetto!
how well does it work when the tire is wet? does the loss of traction affect the efficency
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.
Grande!! Complimenti!
I want to use my everlast welder to convert my bike to electric. Thank you for the ideas.
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.
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.
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!
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?
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.
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.
You are brilliant ! great job !
Really like your ebike Valentin. I am going to attempt a project like this myself. Nice and simple design.
adversely would peddling the bike generate current to recharge the batteries?
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!
Bellissimo progetto , barbaramente efficiente :)
The question which bugs me, how about rain? wouldn't the friction between the motor and the tire be influenced if it is wet?
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.
Well done...!!!
Best wishes from Bavaria / Germany. :-)
So what ESC are you using? And does the ESC have built in breaking?
The idea and the construction principle is ingenious and impressive. But couldn't you have done nice cuts and proper installation?
How does the braking work? or would you have to turn it off and then use the breaks on the handles?
simple yet effective has potential
its wonderfull but the tires runing out in less times? because the force of friction is actionate directly to the tire, i think to use rackwheel to reduce usage of tires, see you
is possible to create a switch to modulate the speed? Greta work =)
BRILLIANT
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?
If u pedal without the motor will it charge the battery if not u should implement a system like that
La idea es buena y sencilla. Además burla la estúpida legislación.
El único inconveniente son las baterías. Ya que las que has puesto son de plomo, y tendrán una vida muy corta debido a que no soportan bien los ciclos de carga/descarga.
Friction drive or coupling. Simple, yet effective when done right. Nice, good job.
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
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!
very nice job! What rpm range is that motor? And are deep cycle accu's preferable or just regular car accu's?
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.
Does motor still running if you have to break in case of emercency or you have some sort of system of protection?
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.
ok is there a speed controler or just on off one speed?
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).
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!
Hi which part is there on the motor that is rotating the tire
Wie gut kommt der 300W Motor Hügel bzw. Berge hoch und wie gut wenn man ihn unterstützt?
isn't it hard to balance when 1 side is heavier than another??
Pretty neat that, well done
wouldn't it charge when you pedal without using the battery
Antonio Valencia doesn't need this bike..,he is one!!
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
Looks like you used a can opener to modify the fender, am I right?
you should make a return circuit with a diode so when you pedal or coast, it charges the
batteries
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.
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!
You can charge battery when driving downhill
Hey nice video. Could you please make a assembling video? I’m sure that would help a lot.
it wolud be awesome if you could charge the battery by pedaling or by going downhill
can you recharge the batteries by using the peddles
great job buddy thanks for the idea
I'm sure he can just stop the bike and take a break whenever he wants to. I mean, it's his bike after all. It's not like someone put a gun to his head and said "no breaks for you, ride this or die
!".
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.
Simple and effective, well done. How did you get the wooden wheel to stay on the motor shaft ?
nice! does the engine "eat" the rubber of the tyre?
if you meant "brakes" as in the devices used to physically stop the bike, all he has to do is turn the motor off and apply them.
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!
can you charge the battery when driving downhill?
What do you use for the motor to touch the wheel?
What exactly is the rubber drive wheel attached to the motor? Where did you source that or did you make it yourself?
good idea, you can hide it and its good enough for most purposes
Simple and nice :)
Can you recharge the batteries by pedaling?
That is sick you are a genius haha Keep up the vids I love them!! Thank you!
You mean a tandem bicycle :] My guess is that either motor will fail or the battery will overheat and melt. But, it "might" work as a help drive, meaning you combine the pedal power with the electric motor power. Lets say that the rider has 80kg = 35km/h, then 200kg=14km/h, IF the speed vs load is reverse linear, but I seriously doubt that a 300W motor has enough power or torque to do it, unless you do some kind of transmission. But hey, I'm only guessing, don't take this too seriously. Cheers
It would be amazing if you could charge the battery by manually pedaling.
can u tell me the measurements of that wheel used for motor
Hello, I want to ask how many miles it takes with a battery charge
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?
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 :)
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?
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?
Ok for Evel Kanevil to jump the Grand Canion?
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?
thx.
Have you tried corrugated spindle pressed with a spring?
awesome .. could you explain how is the battery charging system?
how it works?
10Ah is the capacity of the battery, not maximum current! Lead acid batteries can easily supply 50-100A.
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?
what about the breaks ?
if you can change it so when you pedal it charges the battery, you more or less have unlimited power.
thats really amazing ! i want to do this
