The Golden Motor is fun, so long as you don't go more than 6-8 miles. =P But once you heat that internal controller up, BLAM! It cuts out.
Here is a short video of the older E-Bike that I'm riding right now. (Until the speed demon is done) Don't ask me why the video is sideways. I filmed it with an iPod, and sometimes the software can't keep up with the potentiometer.
^^ Look how rusty my chain and freewheel are!!!! LOL
