A fully self contained bicycle hub motor known as the GreenWheel has been developed by students at MIT that contains the motor, batteries and motor controller all within the hub enclosure. Very similar in concept to the E+ we reported on earlier this week (which we have been informed by a reader is a reincarnation of a Wavecrest Electric bike), but taken one step further by combining the batteries together with the motor in a single hub instead of putting the batteries in the front hub and motor/controller in the rear hub as on the E+.
The only external part of the GreenWheel system is the handlebar-mounted throttle that is connected wirelessly to the electric motor in the wheel, so absolutely now external wiring is required along the bike frame. The hub motor is spoked into a standard bicycle wheel and is powered by Lithium ion Nanophosphate batteries supplied by another MIT firm A123 Systems. … More info
