You provide a lot of honest knowledge to the public, and on top of it share the fruits of your journey. You upload the results, the final CAD files, the methods and the means. Hats off to you, sir. May your channel be as plentiful as your great work. ...129

@jeffreyturck2743 years agoVery well done, i like that you included the failures, well i believe failures are the only way you can learn the best ways that work. I am impressed and certainly think you have all the right stuff to succeed in any project you choose. A lot of what i see you working with can be "reverse engineered" into other fields, i wish we were neighbors i need your expertise to combine with my wind turbine projects to make power like nobody else can. ...2
@
@olivertrevellyan97893 years agoi 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 through a servo that can mesh a gear to the belt, I would love to see how you would do it. ...6

@
@jmcbike2 years agoI 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. ...2

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. ...8

@renzolieverloo12554 years agoHi 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. ...5

@
@jhsevs4 years agoThis 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. ...14
