7. Slide the wheel forward in the dropouts until the wheel can be removed.

• Refitting the rear wheel
1 . Make sure that the system is switched ‘Off’.
2. Rollerbrake bikes: make sure that the distance piece that
centers the roller brake onto the hub is correctly in place.
3. Make sure that the flat portion on the left hand side of the
axle aligns with the left hand side dropout.
4. Make sure the groove in the rear axle is facing up (12 o’clock
position). Put the chain on the smallest rear sprocket and slide
the rear wheel into the dropouts. Make sure that the axle moves all the way back into the dropouts.
5 Tighten the rear wheel nuts equally and evenly to a torque of 40 Nm. Otherwise the system might
not work properly. If you do not have access to a torque wrench, you can use a normal wrench, but
have your dealer checked the tightening torque of the nuts at the earliest opportunity.
Warning: On bikes without a derailleur, the chain may not be adjusted too tight (measured at the
most tight point in the chain), else the system does not work properly and can the rider lose control
of the bike while riding. Adjust the chain so that there is 10-20 mm of slackness in the chain at its
tightest spot when a force of about 100g is applied.
6 Reconnect the rear brake.
Rollerbrake bikes: make sure that the bolt for the brake arm is securely tightened.
7 Reconnect the motor connectors.
8 Activate the system.
9 Test ride to make sure that the system works.
10 Check if the rear brake works.
Notice: Switch the system off before you disconnect or connect the connectors of the motor.
You may experience strong sparking and possibly electric shock if you fail to do so.
• Removal / refit of the front wheel
