Building an electric bike isn't easy, especially when using unconventional electronics, such as a drone motor. After 3 years of development, I have a bike that I'm finally happy with... but who knows what I'll change next...

i think the next best idea for the new version would be to have a functional gearbox type arrangement, therefor you can have lots of torque down low but still a fast max speed. Whether is is through a servo that can mesh a gear to the belt, I would love to see how you would do it.

@jmcbike Год назад

I built a display similar to yours, which keeps track of amps and volts (watts) vs time, so the battery charge can be tracked. It also allows converting the controller from a speed control throttle to a watts controlled throttle, as you mentioned you did. I like that, it is more motorcycle like and you can then set preset power assist wattage amounts- speed might change but watts can stay at the preset level. My motor is a Bafang BBSHD with the internal controller.

@iMidnight_ 4 года назад

@jhsevs 3 года назад

This video has given me a ton of inspiration and ideas. One of which being using the crank as the speed controller, either by using an encoder directly, or passing the crank through a back sprung differential with a potentiometer mounted to the differential bell. The latter would allow for you to use another pot on the handlebars to set the max amount of electric assist, and your additional pedal pressure while cycling normally would propel you forward electrically. This way you would still have to cycle for the sake of working out, but you would get additional range and some help up the steepest hills. This could motivate some to get on the bicycle seat more often.

@DanielinLaTuna 2 года назад

Fascinating discussion and demonstration. By the way, Harley Davidson uses the two belt system, with the motor driving the tranny, and the second belt driving the rear wheel. I wonder if it's to make up for an underpowered motor.

@juggernautz 2 года назад

Harley designed the 2 belt system to reduce sideways torque and its a lot quieter. A 1200cc Harley has 85 horsepower and up. The 125 cubic inch engine produces 130hp. Similar hp to a Toyota Prius. Custom engines can be 2.5 liter or 3 liter beasts. Also a large rear sprocket increases power too. For a 1000 pound bike they haul arse!

I think you are spot on with this video, as well as your assumptions on your audience. I’ve gasping at name brand electric bike prices and what you get for the money. Of course there is trial and error + hundreds of hours work involved in doing this DIY, but when it’s a hobby, all that matters is the enjoyment (and cost of parts). The idea that I can convert my existing bike to electric is tempting in so many ways, and your videos have shown that while it is a lot of work, it’s not black magic.

Hi Tom, Really nice video recab of your learning curve during the build of your own ideal electric bike. I can imagine your feeling of gratification when you had reached your desired result after 3 years of work. It's not about having an electric bike, then you just buy one, its about knowing how everything works and creating your own optimal design. Pushing your own knowledge to get the most out of every mechanical and electrical detail for optimal results. People who even take time to create a video about there years of work and contribute by sharing their knowledge deserve at least a thumb up. Again, impressive piece of engineering Tom, thanks for sharing. Not one second of my time was wasted watching this video.

Always great to see innovation and enthusiasm on your videos, but in this case it's a shame that legality of elexctric bikes isn't discussed at all so encouraging people to build bikes which are illegal to use in the UK - anything above a 250W motor with an assistance cut-off at 15mph would make the bike a motorcycle and need a licence and insurance as such.

@robmac3702 4 года назад

Agree with this comment completely. Please say that these are private roads otherwise what you are doing is illegal. Also, as this is a new kit, a throttle is also illegal. I do like how you are designing new ways for an electric bike but maybe look at being more efficient by powering the crank rather than just the rear wheel. There are kits out there for a crank with a freewheel in them so when powering the crank, the crank arms wont spin.

@@rodrigoc.goncalves2009 Whilst that is very true, as a working engineer, one of the main prorities of a task is to design something which is in the confines of your local laws. After that, design using best practices such as British Standards and ISO's. There are many people hot rodding ebikes on youtube but one of the main reasons many people watch Stanton is for the informative and logical approach. By not putting in a disclaimer in the video he is putting himself at risk of prosecution which isn't very logical and may stop the great video output that we can expect to watch from him.

One thought on the formula - Kv x (Motor pulley / Wheel Pulley) = 10 is good This seems to be true for 26 to 28 inch wheels but if your building something with say 14 inch wheels you can double that 10 to 20.

Sometimes "engineering" is admitting that that thing you did was stupid and fixing it. Over and over and over again. Failure is always an option.

You make some awesome engineering video's, keep up the good work!! :p I have a question about the motor kV - gear ratio. Were did you find that this ratio has to be a factor of 10? I am currently converting a minibike from petrol to electric, and i calculated this ratio for my build and it's around 16.9. I guess this will be really slugish then. Does this apply to all sizes of motors? Or is it just for the smaller ones?

Really great design and innovative idea. I had the same idea but watching your video cleared a lot of my doubts and buy the way bicycle design is really nice. I will build myself one oneday👍👍👍
