Been new, I might of missed threads on this, however here is my question. The Electric Mountain Bikes seem to be mostly the motor in the crank, which when mated via a gears/freewheel does not allow regen braking by the existing motor. Now regen braking on flat rides might be worth say 10% increase in range, however on a mountain bike, could be a lot more under the right conditions (one ride we do is up like 20 miles and 4,000' up, but has a few ups and downs on the way, so do need energy to ride back as can be 40 miles with some climbing flat sections near the end. So has anyone looked at hub mounted motors/dynamo (like used for lights), either front or rear to give some energy recovery? I could see some energy been recovered in a coast mode on the long down hills, either brake lever activated, or maybe operator switched and then turned off by the front brake or peddling. Thus allowing it not to be engaged while actually cornering or climbing.
