Pros / Cons

Pros

  • According to retailers it fits BSA bottom brackets 68 to 73 mm wide.
  • Display, speed sensor and brake cut-off switches are included in the set.

Cons

  • No torque sensor; assistance only starts after a full crank revolution (heise test).
  • Not usable with a coaster brake because the freewheel sits on the crank.
  • Bafang publishes no official torque figure for this model; the 80 Nm come from retailers.
