I was surprised by this press release earlier today, partly because I’ve already been contemplating doing something like this e-bike just to help save gas money and partly because we live at the bottom of a big hill.  I would love to ride my bike more but don’t have enough energy (yet) to make it up that big hill all by myself.  Something like this could maybe help save money, be good for the environment AND help me learn to love exercise.  Is there a down side?
