Electrified Downhill bike

[johnrobholmes]

I got in some hub motors a few weeks back and laced up a wheel for myself. I ended up mounting it into my old downhill bike for grins and giggles, and so I would have cheap transportation around town. Works out to about a penny per 9 miles of travel at 20mph.

specs:

Rear geared brushless PM motor
Castle HV110 controller
12s2p a123
Magura throttle
Santa Cruz Bullit
Marzocchi Super T fork
Built up by me

Right now it is about 20mph on 36v. I have 12 more a123 cells so I can bump it up to 48v. Yesss, feel the power!! It already pulls wheelies....
