I've got nine ebikes...2 trikes, 2 folders, a hybrid, and 4 recumbents (Revives, SunEZ Sport, Rebike) and to call ebikes "prehistoric" is pretty silly, whether geared or ungeared. They are all AWESOME - Lithium is AWESOME. I can go eighty miles fully loaded up with camping gear and a Bob and be totallly comfortable. Calling them prehistoric when we are on the cusp of a major ebike phenom is so wrong. I don't recall any nanophosphate batteries around in the Cretaceous.
