Pros / Cons

Pros

  • According to retailers it fits BSA shells 68 to 73 mm wide.
  • A French retailer includes display, cranks and cable in the set.

Cons

  • Rated at 750 W, so not pedelec-conform.
  • Retailer torque figures contradict each other (90 to 160 Nm), so none is recorded.
  • Speed sensor and brake cut-off are not in the retailer's list of included parts.
