3.1.

Checking the tyres

The correct air pressure in the tyre is crucial for traction!
We recommend as a starting value:
rider weight /kg
75 kg
110 kg
Get a pump with pressure gauge and vary the air pressure unti l you are satisfied
with the traction and rolling resistance.
The advantages of the 27.5+ tyres, namely extremely high grip and good shock
absorption, can only be fully exploited with low pressure. As a general rule:
• High air pressure leads to low rolling resistance on the road.
• Lower air pressure greatly increases the traction and slightly increases the
rolling resistance.
Too low air pressure can lead to the following:
• Spongy/unstable handling in curves
• Snakebites. Consequence: "flats", damage to rim.
→ If you notice any of these symptoms, increase the tyre pressure!
A tyre damaged by cracks or foreign objects may lose its pressure.
There is a risk of accident!
→ Check for cracks or foreign objects in the tyre.
We recommend that you check the pressure regularly, as bike inner tubes
continuously and inevitably lose air.
3.2.

Checking the brake system

• Pull on the brake lever at standstill. It should not touch the handlebar grip.
• Move the pedelec back and forth with the brake applied. There must be no
significant play. If there is, get to the root of the cause. The brake calliper orbrake
disc may not be tightened. Tighten them to the torque values in the table in
section 9.3.
• For hydraulic disc brakes, the pressure point on the brake lever must be stable.
If the position of the pressure point moves, you should have the brakes vented.
• The brake discs must be free of oil. If there is oil on the brake discs, you can
remove it with an alcohol-soaked cloth.
