GRACE MX II Operating instructions
3. Before each ride
3.1. Checking the wheels and tyres
Before each ride, check:
• The tyres and wheels for damage and any lodged foreign matter. Damaged wheels
can lead to a loss of tyre pressure and other damage.
• The treads on the tyres.
• The concentricity of the wheels by allowing both wheels to spin freely. Poor
concentricity may be caused by damaged tyres, broken axles or loose or broken
spokes. Explore the origin of any rattling noises and where necessary check the
bearings and screw connections.
The GRACE MX II comes with the following tyres as standard:
• Schwalbe Big Ben RaceGuard 60-559 (MX II Urban)
• CONTINENTAL MountainKing 2.2 (MX II Trail)
Observe the tyre pressure information provided by the manufacturer which is
printed on the tyre wall! Exceeding the maximum permissible air pressure when
pumping up the tyres can cause the tyre to puncture!
Note for S-Pedelec variant only: When replacing, make sure that only the tyres
shown below and that tyres must be assembled with a ECE-R75 release. The wheel
circumference can be adjusted via a setting function on the on-board computer.
