Sprockets Vinka T66 for E20

These sprockets are part of the internal gear train of the Vinka E20 mid-drive motor. The gear train converts the motor's high rotational speed into the lower speed and higher torque delivered at the bottom bracket. Worn or damaged teeth can cause a rattling or grinding noise from the motor, vibration through the pedal stroke, or assistance that audibly skips.

Suitable for the Vinka E20 mid-drive motor: 36V, 250W nominal power, maximum torque 80 Nm. This motor is used in city, trekking and light e-MTB bicycles, including models from Amslod.

Replacement requires the motor to be disassembled and is best carried out by a qualified bicycle mechanic or e-bike specialist. Check the motor type on the housing before ordering.
