Jeff Patterson runs Patterson Cycles where he builds custom bikes of the conventional variety but after seeing "Who Killed the Electric Car" he decided to try a full size electric motorcycle. The end result is ShocKing.
The handbuilt hardtail frame has an aftermarket springer fork and Road King wheels. 6 batteries in series yield 72 volts driving the DC motor out back. A mountain bike shock suspends the seat. The tank hides a couple of necessary parts, in the left side is a Zyvan battery charger, on the right is a DC to DC converter, to run the lights.
Jeff says it gets to 60 mph very quickly but doesn't give any range numbers, probably the major limitation of the bike, but it has that simple clean look. Could be a lot of fun.
