Also what is it like to ride an ebike with a Gmac powering it because of the regeneration?
I didn't notice the regen on the HillEaster until I was coasting down a steep hill. I wasn't going anywhere near as fast as I thought I should be going and thought the brakes were sticking. After talking to the shop owner, who was along for the test ride, I realized it was the regen in action.
With the GMAC motor there is always a bit of power consumed to cancel out the drag from the regen.
