Finally I finished my second e-bike project. I am pretty new to this, but I am fascinated with e-biking, so that lead me to build another e-bike for myself. Spec
Bike: Mongoose Rockadile ALX 2010 with hydraulic disc brakes
Tires: 26" City Jet slicks
Hub motor: Crystalyte HS3540 (sensorless) laced in Exal rim with 12g Sapim spokes
Controller: Crystalyte 48V 40A (sensorless)
Bike computer: Cycle Analyst DP with speedo cable
Battery pack: 6x 6s 5Ah Zippy Lipos connected in parallel and in series which makes 15Ah at 44.4V (50V fully charged)
Battery bag: home made out of a waterproof rip resistant strong nylon and some thin foam inside the bag walls for extra softness and protection (If anyone is interested, I can send some sketches of the different layers etc)
I will be using it mostly for commute to work and for fun. I am planning on increasing voltage to 66V or more later on, but first I need to learn how to safely ride an ebike!
