7.5.1
Wheel
1 Hold ebike.
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 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
Notice
If the tire pressure is too low in the tire, the tire
does not achieve its load bearing capacity. The
tire is not stable and may come off the rim.
If the tire pressure is too high, the tire may
burst.
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 15psi 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.
Figure 135: Tire pressure in bar (1) and psi (2)
Verify tire pressure against the value noted in
the ebike pass every 10 days as a minimum.
