I'm inclined to agree. Just thinking this through I would tend to think that in order for a regen system to be of any practical use it would have to be quite heavy. Even then how much more energy is it going to produce and is it really something that would make a big difference in range? If it only gives you an extra 5 miles I don't think it would be worth paying for. Personally I'm wondering if anyone has yet commercially made a decent sized / weighted fuel cell that could power an ebike motor for extended range.
