this is my 72v, 30a, 20" folding bike for commuting on the subway here in san francisco(folding bikes only during rush hour)

I wanted something with more torque than my 48v BMC build, and boy did I get it, a quick test drive shows the biggest problem is uncontrollable wheelies! :mrgreen: :mrgreen: :mrgreen:

it's a E-crazyman 72v controller, and a Ebikekit.com 20" wheel, with 2 bosch fatpacks in series for 80v hot of the charger.

Many thanks go out to Lyen for putting it together for me after I botched the wiring badly. he fixed it all up and put it together(I then cut his neat wiring apart to add the battery) The battery is my sloppy workmanship, but all his work was top notch. I highly recommend him.

Looks good. I'd get a wheelie bar mounted with adjustable tension.
 
Not sure. At least 8.5 miles on 6.6 ah. I need to get my CA off my mountain bike and move it over to find out, but I think about 10 miles. But that includes a pretty decent climb, and there's still no chain, so that's motor only.
