Wheel
1 Hold pedelec.
2 Hold onto the front or rear wheel and try to
move the wheel sideways. In doing so, check
to see if the wheel nuts or quick releases move.
If the wheel, the wheel nut or quick release
moves sideways, take pedelec out of service.
Contact specialist dealer.
3 Lift pedelec slightly. Turn front or rear wheel. In
doing so, check whether the wheel deflects
sideways or outwards.
If the wheel deflects sideways or outwards,
take pedelec out of service. Contact specialist
dealer.

7.5.1.1 Checking the tyre pressure
Notice
If the tyre pressure is too low in the tyre, the tyre
does not achieve its load bearing capacity. The
tyre is not stable and may come off the rim.
If the tyre pressure is too high, the tyre may
burst.
Tyres are wear parts and wear away due to
fatigue, storage, environmental influences or
mechanical impacts. Only optimum tyre pressure
will guarantee effective protection against
punctures, lower rolling resistance, a longer
service life and greater safety.
Air loss
Even the most airtight tube will lose pressure on a
continuous basis since the air pressures in a
pedelec tyre are significantly higher and the wall
thicknesses significantly finer than in a car tyre.
Pressure loss of 1 bar per month can be regarded
as normal. During this process, the pressure loss
is significantly faster at high pressures and
significantly slower at low pressures.
Checking tyre pressure
The permitted pressure range is indicated on the
side of the tyre.
Figure 135: Tyre pressure in bar (1) and psi (2)
Verify tyre pressure against the value noted in
the pedelec pass every 10 days as a minimum.
