I want to add regenerative braking to my bike, not for energy recovery, but as a braking supplement/assist on long downhills. Is anyone doing this and how effective is it?
A 3 phase hub motor IS a generator when freewheeling. All that's needed to create braking resistance is a load that can be switched in on demand. In fact, a short circuit might be effective if heat buildup in the windings can be managed. As an electrical engineer, I understand this much.
My question is, has anyone done it and how effective is it as an assist, not the primary brake?
