23.4 Rim brakes (V-brakes)
If improper additional parts are used in the
braking system (power modulators), this can
cause serious falls. When using power modu-
lators, the required spring force depends on
the total weight of the pedelec.
23.4.1 Adjusting brakes
Your FLYER will be handed over to you by your
retailer correctly set up. There should be a gap
of 1-1.5 mm on either side between the brake
shoes and the rim. As the brake shoes wear,
the gap grows over time, which increases the
amount you are required to pull the brake le-
ver. You should therefore check the brake at
regular intervals and make adjustments if the
lever distance is too large or the brakes are not
working correctly.
You can identify the wear level of the brake
shoes from the notches on the shoes. If these
are no longer visible, the brake shoes have to
be replaced by a specialist retailer.
Test the functionality of the brakes as follows:
• Check the performance of the brakes by
pushing the pedelec forwards and applying
the front and rear brake levers in succes-
sion, just as you would during strong peri-
ods of braking.
• The front brake should brake so effectively
that the rear wheel lifts off the ground.
• The braking force on the rear wheel should
be so strong that it locks.
23.4.2 Setting the distance of the brake pad
to the rim
The distance between the brake pad and the
rim can be set by turning the cable adjustment
screw on the brake lever. If you turn the adjust-
ment screw inwards and clockwise, you can
increase the distance between the brake pad
and rim. If you turn the adjustment screw out-
wards and anti-clockwise, you can reduce the
distance between the brake pad and rim. There
should be a distance of approx. 1 mm between
the brake shoes and the rim.

Setting the pull cable
The braking performance of
modern rim brakes is very
strong. You have to get used
to the braking performance of the V-
brakes. Only apply the brakes in doses.
You have to practice making emergency
stops so that you are able to safely ma-
noeuvre your pedelec during very strong
braking manoeuvres.
