I am an ebike freak. It's so nice to finally see some ebike enthusiasm on hn! If you have any questions about ebikes just ask me. If I can't answer I can at the very least put you on the right path. If you want to get into ebikes, check out the endless sphere forums. It's the defacto online headquarters for everything ebike. Doctor bass and live-for-physics-luke are two of the most formidable experts on there. Luke used to be in IT and now designs the battery systems for zero motorcycle. Great guy. If you don't understand why electric bikes or transportation is cool then Google "lightning electric motorcycle" and become converted. Cheers.
