Summary

    Complete conversion kit based around the Shengyi SX2 mid-sized silent geared hub motors, but modified with a welded clutch for regen capability.

    • Baserunner motor controller tucked neatly in a downtube battery, the CA3 with accessories and pedal assist systems.
    • The motor has built-in speed and temperature sensing for automatic thermal rollback with the CA3 so that there is no risk of burning up the motor on long climbs.
    • This setup includes everything configured out of the box for a lightweight commuter ebike with pedalec control.

    For a full explanation of the various drop-down choices and a comparison of this package versus other motor options, see our Grin Kits Info Page

    For details on this hub in particular, see the Shengyi X1 / X2 Geared Motor Info Page

    For details on the PAS/Torque sensor selection, see the PAS Info Page

    *For installation of the SX motors with welded clutch mod, we highly recommend that you install the v7 regen torque arm on the non-cable exit side of the axle. If there are fitment problems that prevent you from doing this and you need to install the torque arm on the cable exit side of the axle, we recommend reducing your max torque to 30nm in the controller to prevent axle breakage.*
