I want to put forth the notion of "one bike": A bike for commuting, as well as mountain biking. Riese Moeller makes a commuter bike with mountain bike suspension and dual batteries. The problem is that it costs ten thousand dollars, making it cost prohibitive for many folks, including me. I don't understand why one of the American companies does not offer such a bike, since RM has proved that a market exists for such a bike. I bought a Vado 1.0. I was able to sell my car, and since I live on social security, this was helpful. I have put over two thousand miles on the Vado in eight months and I am happy with the bike, except that I can't use it to go mountain biking. If an electric bike was available similar to the RM "Delite," I believe is the model, for even six or seven thousand, I would sell my Vado and upgrade. Also, RM has an option for a carbon belt drive instead of a chain and derailleurs.
