I am pumped!!! R&M initially had the New Charger & Supercharger listed on their website with a December 2017 release date. Then everything disappeared and I learned that R&M was waiting upon UL certification. I decided months ago that the New Charger HS, GT, Nuvinci (Sorry, if I did not get the name right.) with the dual battery option was the e-bike for me. I like the idea of the powertube battery on the downtube in conjunction with the standard Bosch 500 powerpack. With this configuration, I think the additional battery does not have to be attached all the time. It would only be necessary for longer rides! Therefore, I would have a more stealthy e-bike when only using the powertube. Please tell me if I am right? How soon before I can place my order?
