DETAILED MANUAL

Mounting of the rim differs bike to bike. For all bike types we recommend to use the torque arm. See Figures
2, 4, 5. The torque arm will eliminate the reaction torque on axe (Fig. 6). Torque arm is partof the optional

accessories and is not included in basic package.

In addition, you must dismount the freewheel shimano gears. To dismount the freewheel use a special pinion
puller (Fig. 1b). The rear hub motor is ready for mounting freewheel with screw pinion. For most bikes
equipped with 7 gears shimano wheel is a screw pinion. For bikes with 8 gears or more gears is not
recommended to use the rear hub motor because here is a potential of many complications during
the installation. For bikes with 8 and more gears we recommend to use the front wheel hub motor.

The cable come out on left side of rear fork when the bike is in normal position.

After installation the hub motor you will need to adjust the sorting of gears. Its needed to avoid a collision
with the hub motor.

In any case, it is necessary to ensure tight connection nuts, washers and fork surface. Insufficient
nut tightening may cause wheel dropping out of the fork. The connection between wheel and fork
must be firm and stable (Fig. 7).

CAUTION

When you install the hub motor to the rear wheel (Fig. 8), proceed the same way. There are only
following differences between front and rear wheel installation.
