Installing the rear wheel
• Guide the rear wheel axle into the two dropouts and make sure that the brake disc (on models with
disc brakes) is inserted between the brake pads
• Also make sure that the flat area at the left of the rear axle (torque reaction collar) is aligned so that it
fits into the left dropout
• Install the rear wheel with both sides of the axle inserted all the way in the dropouts
• Tighten the axle nuts on the rear wheel with 40Nm/ 30lb-ft (= VERY TIGHT!). This torque is essential for
the correct function of the propulsion system. If you do not have a torque wrench, use a normal ring
wrench. Have your dealer check the torque of the axle nuts as quickly as possible. Use only the original
axle nuts; otherwise you run the risk of damaging the axle threads.
• Keep the motor cables clear of the brake disc (on models with disc brakes)
• Pluginthecableconnections(POWER

) and place the larger neoprene
cover over the plug-in connections, and the smaller neoprene cover closer to the disc to prevent the
cables from wear.
• Now replace the cable pull. Re-install the cable guide of the rear wheel brake (V-brakes only), and
correctly adjust the rear wheel brake.
Maintenance and Care
We recommend to have the spoke tension of the rear wheel and the torque of all screws checked by your
qualified dealer after the first 200km.
In order to ensure extended use of the propulsion system, all plug-in contacts of the system should be
checked every two to three months and cleaned with a soft and dry brush, if necessary. It must be ensured
that no dirt or humidity penetrates the battery docking station when the battery is removed. The electric
motor is a brushless DC-motor that does not have to be serviced.
