drop out slots and tighten the axle nuts to the torque specified in the manual. Reconnect the
two halves of the quick release connectors, taking care to ensure the pins and alignment
arrows align correctly. Re-clip the cable to the frame, ensuring that the cable cannot rub
against the tyre and that the cable exits in a downwards direction from the axle to avoid
water ingress into the motor. Refit the rubber top hat cover.
