These reports of ebikes are interesting, because in the Washington DC area, the only ones I see are the rental ones from Capital Bikeshare. The few ebikers I see behave well. They go about as fast and generally behave about like the sporty people on road bikes. No complaints from me about them. I don't think I want one, though -- as long as I can make it up the hill to my house at the end of the trip, why bother? I wonder why they are less popular here than elsewhere. Perhaps because this is an area full of Type A personalities who think ebikes are for weaklings.
