14Installing the rear wheel• Guide the rear wheel axle into the two dropouts and make sure that the brake disc (on models withdisc 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 itfits 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 forthe correct function of the propulsion system. If you do not have a torque wrench, use a normal ringwrench. Have your dealer check the torque of the axle nuts as quickly as possible. Use only the originalaxle 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)• Plug in the cable connections (POWER 1 before COMMUNICATION 2 ) and place the larger neoprenecover over the plug-in connections, and the smaller neoprene cover closer to the disc to prevent thecables from wear.• Now replace the cable pull. Re-install the cable guide of the rear wheel brake (V-brakes only), andcorrectly adjust the rear wheel brake.Maintenance and CareWe recommend to have the spoke tension of the rear wheel and the torque of all screws checked by yourqualified dealer after the first 200km.In order to ensure extended use of the propulsion system, all plug-in contacts of the system should bechecked every two to three months and cleaned with a soft and dry brush, if necessary. It must be ensuredthat no dirt or humidity penetrates the battery docking station when the battery is removed. The electricmotor is a brushless DC-motor that does not have to be serviced.POWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXP O W E R E D B Y B I O NXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYB I O N XPOWEREDBYBIONXP O W E R E D B Y B I ONX15mm40Nm15mmPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXP O W E R E D B Y B I O NXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYB I ON XPOWEREDBYBIONXP O W E R E D B Y B I ONX15mm40 Nm15mmPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXP O W E R E D B Y B I O NXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYBIONXPOWEREDBYB I O N XPOWEREDBYBIONXP O W E R E D B Y B I ONX15mm40 Nm15mm12
