Hi
I have a 48volt pie and a headway 48volt 10AH pack running with my DIY SWB recumbent. Holy crap is this a lot of fun! With my Garmin GPS she runs at 43kmh with my 195lbs on board.
The acceleration and throttle response is very satifying.
I got the pie from Gary at goldenmotor.ca in December 2009. From what I read here the usb programming is not possible. It would be really cool if the upgraded controllers were available as an upgrade kit.
All in all I am really happy with the MP.
Cheers from Wolfe Island Ontario.
