I am fascinated by many of the people who are posting on this forum. Most are trying to "push the envelope" in one way or another. Most recently I have been reading about transmissions and gearing - how to get more speed or range out of a given motor/battery combo. Most of the posts that I have read are trying to push a lot of power through bike gearing systems - IG hubs, Nuvinci, etc. Many people have discovered that these things fail when put under the kind of stress that the rider wants out of them. I know that the bike parts are an easy choice because they are usually light weight and were designed to be bolted onto a bike or into a wheel. Motorcycle parts are probably heavier and maybe a little more specialized than bike parts. Still, has anyone done any calculations - especially re: transmissions - as to how much power a bicycle tranny can handle and when to call it quits and look for a lightweight motorcycle part?
