1). Simplify to make a electric-scooter. 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

Difference between V3/V3I/V3TI

1. Phase wire exit from thread side, which is easier to mount on bike and it looks better.

Left is V3TI, right is V3/V3I

2. Phase wire change to integrated one instead of standard loose one, which improved from IP54 to IP65.

Regular V3 uses # Standard wire #

V3I/V3TI use # Integrated wire #

3. Add brake spacer as default, which is thinner to avoid scratch phase wire by brake disc.
