Do they or can they reverse the flow when going downhill to recharge the

Regenerative braking is a fairly common feature on electric bike motor
controllers, or it was last time I looked. However, I think it's more
of a feel-good thing than a practical feature; the cumulative
inefficiencies involved mean that of the energy that goes into getting
the bike moving, only a very small proportion ends up back in the
battery.
