    Left-Hand Crank Drive, 35 mph, highly versatile build

    Well I finally got around to taking the advise of some of you e-bike veterans... I took apart my battery and re-configured it into a shape that fits in the main triangle of my frame. The bike handles much better now. It takes speed bumps and fast turns much better, and it's not so unwieldy to...

    amberwolf, Thanks for the comments. The motor is a Chinese electric tricycle model. It's made by Unite Motor, P/N MY1122ZXF. Nothing fancy...you can buy it at electricscooterparts or tncscooters. I forgot to mention that it is brushed. The biggest downside is the open cooling fan...it makes...
