In Pennsylvania an "assisted pedalcycle" is any pedalable 2 or 3 wheeled bike with a 49cc or smaller engine, with 1 1/2 horsepower or less, capable of a top speed on the flat of 25MPH or less, have an "automatic" transmission(one speed or a CVT, not manually shifted), and must follow all bicycle regulations and laws. The rider must have a valid driver's license. That's it. As long as you meet the regs you don't need a registration or insurance. In Pennsylvania it's a bicycle.......period. If you wish to register it as a moped, be my guest, but it is difficult and completely unnecessary. The one catch is, they are banned from all state parks by the agency that runs the parks. I suppose with a registration tag it would be okay to ride it in a state park, but you may have to argue with a ranger.
