The purpose of the list is the discussion of power assistance for primarily human powered vehicles. Vehicles is a broad term which includes anything from bikes, upright and recumbent, to light cars and non-land transport. The only limitation is that the prime power source must be human.

In reality, most of the discussions centre around electric bikes and trikes. There's an extraordinary range of expertise and opinions here on the list and we cover both home and factory built machines.
