About a year ago, my dad and I had the idea to convert a beach cruiser bike into an electric motorcycle. We purchased the bike and all the parts necessary and got to work. We modified the frame and rebuilt the bike from the ground up. When we finished, we were extremely satisfied with the results - a 48 volt, 15 horsepower board track racer.
We started with a Felt beach cruiser because it had the right look. We wanted a beefy bike that could fit all the components. The goal was to keep the center of gravity as low as possible. Here are the rest of the main components we purchased: - Briggs and Stratton Etek motor (now discontinued) - Alltrax AXE 300-amp programmable controller - Magura 0-5K ohm twist-grip throttle - 4 x 12V, 21Ah sealed lead acid batteries - Avid BB7 mechanical disc brakes (160mm rotors) - #35 moped chain - 13-tooth drive sprocket - 66-tooth rear sprocket - big power switch - 300-amp fuse - 8 1/4 in. stainless steel motor mount (this replaces the original bottom bracket)
