The gear shifting is fast and good.

Mounted on an external 10-speed Saba Pike. In the app options, you can select Shimano, SRAM, L-Tube, etc. For mounting on a Mini Bell or Tri-Fold bike, Just select L-TWOO, MTB and adjust slightly to fit, and it will be done quickly. If you try to set Shimano or Sram randomly, it only gives an error. And just unscrew all the H and L limit screws and start. If you tighten that, it gets stuck and won't shift to first gear.

You can enjoy the fun of electric vehicles at a low price. It would be nice if the battery was sold separately.
