In John Bidwell's "The secrets of El Ninja" which is available through www.21wheels.com, he gives a company contact that can make a 72 tooth 40 pitch sprocket for $100 for your bike on a cnc machine. Use a 12 tooth 40 pitch driver generally, depends on your desired top/battery voltage. I used the original driven 50 pitch sprocket with a jack shaft because I had a torque converter on my bikeTry not to modify the frame geometry, find batteries that fit, 6 batteries would be much better for a 50+ mph top with your desired range. Weight is the enemy, unless you like a lethargic performer, it is a bike and should handle like one, not a turd.
There is a 1000+ lbs Electric Harley out there, now that's a turd! I am going to post construction pics, like 100, on a photo site this week, I'll let you know where.
