This can cause the drive belt to skip or slip
off and become damaged. This type of dam-
age to the drive belt can cause it to tear
unexpectedly, causing you to slip off the
pedals. There is a risk of accident and
injury.
Do not ride the ebike on surfaces that are
covered with snow, ice or mud.

WARNING
The water jet from a high-pressure cleaner
can cause damage to the tyres or drive belt
that is not visible on the surface. Compo-
nents damaged in this way can fail unex-
pectedly. There is a risk of an accident.
Do not use a high-pressure cleaner when
cleaning the ebike. Have damaged tyres or
drive belt replaced without delay.
The tyres establish the contact with the
road surface. They provide grip and trac-
tion and, depending on the tyre pressure,
absorb small bumps.
Although the wheels of your smart ebike are
manufactured with great care and deliv-
ered trued, this does not prevent the spokes
from losing tension on the first kilome-
tres. For this reason, you should regularly
inspect the tension of the spokes and have
them re-centred by a smart dealer.
Tyre pressure
G
WARNING
If the tyre pressure drops repeatedly,
inspect the tyres for foreign objects. Check
whether the tube or the valve is leaking.If
the tyre pressure is too low, the handling
characteristics of the ebike may be
impaired and could cause you to fall. There
is a risk of an accident.
R
Always replace a damaged tube.
R
Before mounting a new tube, remove all
foreign objects from inside the tyre.
Check the tyre pressure regularly, at least
every 14 days. Only correct tyre pressures
when the tyres are cold. The pressure of
warm tyres should only be corrected if it is
too low for the current operating condi-
tions. Warm tyres always have higher pres-
sures than cold ones.
The tyre pressure changes by around
10 kPa (0.1 bar, 1.45 psi) for every 10 † (50
‡) change in ambient temperature. If you
measure the tyre pressure in enclosed
spaces where the temperature differs from
the outside temperature, you will have to
correct the measured value accordingly.
When the ebike is ridden, the tyre temper-
ature, and with it the tyre pressure, will
increase depending on the speed and the
load on the tyres.
Always check the tyre pressure with suita-
ble measuring equipment, e. g. a stand
pump with a manometer. As your smart
ebike's tyres are fitted with robust punc-
ture protection made from plastic, you can-
not check the pressure simply by pressing
down on the tyre with your thumb.
Tyre pressure specifications can be found
in the "Technical data" section
(Y page 70).
