Adding An Engine to A Bicycle

Unless something has been missed, it appears that all the torque of the engine will be transmitted to the hub through the spokes, which is not a satisfactory method. That wheel is not going to last very long, although probably longer than the tyres and brakes.



In England this adaptation creates a moped, for all intents and purposes, and is therefore subject to the myriad rules and regulations governing its construction and use. I doubt that such a device could be legal as things stand.

As an aside, why is it that almost all YouTube videos dealing with anything touching on self-reliance, from building a home to home brewing, are made by Americans? Is the English genius for innovation and invention moribund or is it that we just don't proclaim our achievements as readily as our trans Atlantic cousins (not to mention our northern neighbours)?
