I am not the biggest fan of the electric bicycle... or any sort of electronic assist for that matter

but... I am sure that these things have their place
anything would be better than our current car culture

something like this could revolutionize pubic transport
the DC Metro Stations involve walking... buses... bus transfers etc
something like this could allow people to go from their house to the Metro... to the office
and then back again!
