Maintenance
4. Disconnect the front brake:
- V-brakes,
Magura brakes: release the front brake.
- Rollerbrakes,
unhook the cable and housing stop from the brake.
5. Loosen and remove the axle nuts and washers.
6. Lift the bike so that the wheel can be removed. Take care not to lose the two torque blockers.
• Refitting of the front wheel
1. Make sure that the system is switched ‘Off’.
2. Make sure that the torque blockers are on both sides of
the axle, with their arms pointing outwards (see photo).
3.
Rollerbrake bikes:
make sure that the roller brake and the distance piece that centers the roller brake
onto the hub are correctly in place.
4. While sliding the wheel into the dropouts, make sure that the arms of the torque blockers are
below the axle in the open ends of the fork legs.
Rollerbrake bikes:
make sure the brake arm enters its retention bracket.
5. Turn the wheel slightly backwards so that the torque blocker arms seat themselves against the
corresponding lips on the fork legs.
6. Tighten the 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 ask
your dealer to check the tightening torque of the nuts at the earliest opportunity.
7 Reconnect the front brake.
Rollerbrake bikes:
make sure that the bolt for the brake
arm is securely tightened.
8. Check if the front brake works.
9. Reconnect the motor connectors.
10. Put the battery back onto the bike.
11. Activate the system.
12. Perform a short test ride to make sure that the system 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 / refitting of the rear wheel
No specific instructions are valid to remove the rear wheel.
When refitting the wheel:
1. Ensure to align the axle with the frame.
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.
2. Tighten the 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.
3. Afterwards, perform a short test ride to make sure that the system works.
