 If the wheel, the wheel nut or quick release
moves sideways, take
ebike
out of service.
Contact specialist dealer.
3 Lift
ebike
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
ebike
out of service. Contact specialist
dealer.
7.5.1.1 Checking the
tire
pressure
Tires
are wear parts and wear away due to
fatigue, storage, environmental influences or
mechanical impacts. Only optimum
tire
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
ebike tire
are significantly higher and the wall
thicknesses significantly finer than in a car
tire
.
Pressure loss of 1
5psi
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
tire
pressure
The permitted pressure range is indicated on the
side of the
tire
.

pressure against the value noted in
the
