This is my first conversion to date. Its a mongoose xr1100 with a 1200w front hub and 1500w rear hub (both ebikeling). 2 48v 20ah batteries. It has a dual throttle set up which is really growing on me. I commute 20 miles on a trail round trip 5 days a week in all weather conditions. I caught the ebike bug and I don't drive at all now.
