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

the Bionx system I was looking at a while back has regenerative braking
activated by a switch on one of the brake levers, it can also be setup
in a training mode where the regen is on all the time to provide a
resistance to pedalling, so that would be like cycling up a very long
hill
