Nah
Its just the Gruber assist drive, big expensive waste of money if you ask me if the guy who sells it says on his website that you cant really tell its helping you then it says a lot, as usually the sales patter for electric bikes is really wide of reality.
Lot of money to pay to be underwhelmed!! nice idea but weedy, whats wrong with a small geared hubbie? this thing was noisy from what I could tell and what others have said, trouble I can see with burying a motor inside a bike frame esp a geared one is that the rest of the frame will amplify the whine of the motor.
Not to mention its lack of cooling and size/power restriction.
Id very much doubt if they sell any
