My Homemade Electric Bike (Score 1)

I built my own electric bike as a mobility aid to get to the local shops. I wear two separate leg braces and pedaling was not an option, I also have a very large steep hill between me and the shops. I bought the Slipstream Electric Bicycle plans and modified them a bit. I've had the bike now for over 4 years and I figure around 3,000 miles, very nice ride.

Max speed 29 mph in about 4 seconds (beat a few motorcycles from the stop, but only if they did not know we were racing)
Range 30 miles with new batteries.
Parts cost $2,000.
Since the photos, I've upgraded to downhill wheels and hubs w/disk brakes.
