With the PM DC motor used on many Ebikes, regen is essentially free.
I've built many EVehicles with dumb old friction drives that drop a
small wheel on the motor onto the front or rear bike tire. The motor is
simply switched directly to the battery (no controller). Going uphill,
it draws current from the battery, trying to maintain speed. Going
downhill, it *regens* (charges the battery), keeping you from gaining speed.
Myself, I don't see why you need electric on a bicycle at all.
I felt that way when I was young. Now I'm old. Without an ebike, I
couldn't ride at all. My knees are just not up to the job of climbing
steep hills, fighting strong headwinds, or riding long distances.
