Home page for Drill Bike
Converted this barn find 550 in 2009 - 2000+ miles on it so far. Added 4 more batteries in 2011 for extended range and a little more kick. Bike is a blast - slow off the line but kicks but between 25 and 45 mph (direct drive - no clutch, no gears). Only 230 lbs. Tricky paralleling the DeWalts but once balanced they stay balanced. The A123 batteries are a best kept secret - you can discharge them 100% and they charge up and ask for more. Over 200 charge cycles to 80-100% and they are still full capacity - no sag in range or voltage. Not much warning when they run out, though - you are blasting merrily along and then... nothing. Check out the discharge curves on the home page.
