Element116,
FYI, kudos to you for even considering biking for a 24 mile one-way commute. My commute is 17 km (about 10 miles) and to me, that's far enough even with an ebike motor. On a separate note, I see that your location is Detroit. I've always had the impression that the majority of Americans (especially in the 'motor city') are addicted to their cars and would never consider biking as a commuting alternative. So I'm even more impressed (I'm from Canada by the way)
