3.8.3 Rim Care and Rim danger: It is strictly forbidden to lubricate the front and rear brakes and
the tires during maintenance of the rim; regularly check the tire wear and tear, and if it is
found that the tread wear is serious, the tire needs to be replaced in time.
3.9 Chain and drive wheel removal
3.9.1 To completely remove the rear wheel, it is necessary to disconnect the main motor cable
connecting the motor to the bicycle electrical system. This operation is best achieved by
turning the bicycle upside down.
3.9.2 Locate the motor cable where it emerges from the centre of the wheel axle on the left hand
side of the bicycle, slide back the top hat protector to locate wheel nut.
3.9.3 Trace the route of the motor cable along the rear stays and locate the quick release motor
cable connector shown in the image above. Disconnect the two halves of the connector,
taking care not to strain the cables, and unclip the motor cable from the frame. Note the
alignment marks on the two halves of the connector.
3.9.4 Loosen the two large motor axle nuts and remove the nut from the right hand side, taking
care to note the position of any tab washers fitted. Unscrew the left hand nut as far as is
possible towards the cable exit from the motor axle, being careful not to damage the cable.
3.9.5 Lift the wheel from the frame dropouts, being careful not to snag or strain the motor cable.
3.9.6 Installation is the reverse of the above. Take care to locate the tab washers correctly in the
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 tire 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.
3.10 Derailleur and gear change
3.10.1 Full details on how to adjust and maintain your derailleur can be found in the Shimano
manual.
If difficulty is experienced with changing gear after initial operation of the bicycle, it is likely
that some cable stretch will have occurred in the gear change cable. To compensate for this
turn the knurled adjuster shown in the centre left hand side of the image below by pulling it
away from the outer cable stop in the direction of the cable towards the rear of the
bicycle and turning it ½ turn anticlockwise when viewed from the rear. This will compensate
for the cable stretch. If necessary, repeat the operation again until smooth gear selection is
obtained or return your bicycle to your Accolmile dealer for further adjustment.
