WHEELS AND TIRES
The wheels on the bike keep you in contact
with the road. They experience heavy loads
during riding over irregular surfaces and
when carrying cargo. Although the wheels
are carefully manufactured and trued, they
settle in after the first few kilometers. After
a short break-in period from 200 to 400
kilometers, your dealer should true the
wheels again. Regularly check the wheels
but additional tensioning is rarely necessary.
CONSTRUCTION OF A WHEEL
The wheel consists of a hub, rim and spokes.
The tire is mounted to the rim in which the
tube is inserted. Rim tape is applied to
protect the sensitive tube from the often
sharp-edged rim.
TIRES AND AIR PRESSURE
The tire provides grip and traction on the
road which is required during braking,
accelerating, and cornering. Furthermore, it
ensures smooth running. Tires can only work
well if it filled to the correct air pressure.
The correct inflation pressure also prevents
failures such as the crushing of the tube
especially when traveling over an edge, the
so called “snake bite”. Snake bites are caused
when going over an edge such as a curb
with a tire pressure that is too low. The man
-
ufacturer’s suggested pressure is indicated
on the sidewall of the tire in bar and PSI.
TUBE AND VALVE
The tire and rim alone are not airtight.
To maintain the pressure on the interior,
TIP!
Always ride with the prescribed air
pressure and check it regularly. Be-
cause Riese & Müller E-bikes are full
suspension (excluding blueLABEL)
you can always inate the tires to the
maximum recommended pressure.
This provides you the best and safest
riding position and low rolling resis-
tance which saves energy. Comfort is
maintained because of the full suspen-
sion system.
TIP!
For the model blueLABEL Charger GT
we recommend an air pressure range
from 1.5 up to 2.5 bar.
Never pump the tires below the
minimum or over the maximum
recommended pressure rating!
The tire can spring from the rim
or burst leading to an accident!
DANGER!
