skewer or bolts are fully tightened. Axle bolts should be torqued to about 20 ft-lbs (28 Nm). Skewers
should be as tight as you can comfortably make them. It is possible for the motor to pull the axle right
out of the dropouts if they are loose.
3) Road test.
Run through all the gears making sure they are shifting smoothly. Use full throttle in each
gear to check for skipping of the drive chain. Keep speeds low at first until you’re sure that everything is
functioning properly and you become familiar with riding with the motor assist.
