The one I currently ride does. I now commute thirty miles per day, Ballard to Edmonds and back again. This guarantees I don't push the bike up Richmond Beach Hill. It also seems to increase battery life when you don't push the battery's limits. I finally installed Shimano pad clips which allow me to change the individual pads rather than the whole brake shoe assembly.
Bicycles are cool.
Einstein rode one. Samuel Beckett rode one. I'm sure Beckett made that connection as well.
