I am looking into using a hydraulic drive system in an electric motorcycle. My reason for doing this is that most braking force on a bike is in the front wheel, so that's the place to recover energy in a regenerative system. However, because of the way the front wheel must move, it's difficult to have a mechanical linkage to a generator (leaving aside the possibility of an electric hub motor, which I believe is heavier than a hydraulic motor of similar spec).
So, I'll need a hydraulic device that can be both driven as a motor (for going) and that can produce pressure as a pump (for stopping). (A similar device, run backwards, will be connected to the electric motor/generator.) My question is, what types of hydraulic pumps/motors have good characteristics when run "backwards?" I've found some motors on surpluscenter.com that say "can be run as pumps;" is there a particular type of motor or pump that works better one way, or about the same either way?
Thanks!
