6.5. Tyres
The tyres are subject to inevitable wear due to fricti on. You can reduce the tyre
wear by ensuring the air pressure is high enough (secti on 3.1) and refraining from
locking the tyres when braking. You will need to replace your tyres if the rubber
tread is so worn down that the braid underneath becomes visible, or if the tyres
have become porous due to ageing and frequent exposure to the sun. The following
secti ons explain how to change the tyres.
6.6. Changing a tyre/tube
6.6.1. Removing the front wheel
The wheels are easier to remove if you put the vehicle into a service stand
or place it upside down on the saddle and handlebar.
In the second procedure, please protect the display and bell from damage.
• Fold the quick-release lever on the
front wheel axle down by 180°.
• Loosen the nut on quick-release axle
some turns. The front wheel may now
slide out of the dropouts of the fork.
Hydraulic disc brakes must not be actuated when the wheel is removed.
Otherwise, the brake pistons will run together completely.
-> Immediately aft er removing the wheel, push a yellow transport lock
between the brake pads. (see picture next page)
6.6.2. Removing the rear wheel
The rear triangle is designed so that when removing the rear wheel,
no prior slackening of the belt is necessary.
• Turn the twist grip to a positi on that pro-
vides easy access to the control cable ends
on the hub interface.
• Fold down the silver pull-stop snap lock
from the hub interface and remove it
