For QS motor 3000w 205 50H V3TI electric motor, it’s new design and especially upgrades for e-bike. It could be 72V 70KPH, available in a variety of sizes, such as 24inch, 26inch E-Bike Wheel, 17inch, 18inch, 19inch moped wheel.
1). Simplify to make a electric-bicycle. Gearbox, transmission shaft, clutch are no need. Which save space.
2). It could be installed in the rear to save more space for battery.
3). Support regenerative braking
4). High efficiency: 85~92%
Main difference between V3 and V3TI
1. Phase wire exit from thread side, which is easier to mount on bike and it looks better.
2. Phase wire change to integrated one instead of standard loose one, which improved from IP54 to IP65.
3. Add brake spacer as default, which is thinner to avoid scratch phase wire by brake disc.
