An eBike is essentially just like a regular bicycle the difference being that it has an electric hub motor (built directly into the hub of the wheel) to provide the additional assistance discussed above. Most hub batteries can even re-charge with manual peddling, but only when the cyclist peddles at a speed faster than the motor can achieve. The main advantage of this design is that no additional transmission system is needed, which increases the efficiency of the drive system. » original news (VIA - hugg.com thanks ;-)
