Page 6: Your Grace Mx Ii
Your GRACE MX II The GRACE MX II is a member of the class of electric power assisted cycles, or EPAC's. The motor only provides assistance when you apply force to the pedals. The force applied by the rider is measured in terms of speed, pedalling frequency, and torque through which the motorised assistance is adjusted. -

GRACE MX II. Using other batteries can lead to injuries and the risk of fire. If you want to stop using your GRACE MX II for a longer period of time (> 1 month), make sure that the battery is charged to approximately 60%, this is equivalent to 3 –... -
Page 14: Switching The System On And Off
When switching on the bike, there must not be any load on the pedals on your GRACE MX II - otherwise, performance of the drive may be impaired. If the GRACE MX II was switched off accidentally while there was a load on the pedals, switch off the bike again and switch it back on without a load on the pedals. -
Page 15: Adjusting The Saddle
If you pull out the saddle post too far, the seat tube may no longer be able to support the saddle post sufficiently. The saddle post may come undone while riding or it may damage or break off the seat tube. Danger of injury or accident! GRACE MX II Operating instructions Page | 97... -
Page 16: Adjusting The Saddle Angle
After adjustment, re-tighten the screw again (see torque table). The brake levers are configured correctly when your fingers can reach the brake levers when your arms are outstretched. The wrist should be stretched out as much as possible. GRACE MX II Operating instructions Page |... -

Page 20: Before Each Ride
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) -
Page 21: Checking The Battery Fitting
• All screws must pre present and have a firm fit. Check the brake callipers for oil leaks. Make sure the brake cables are kink-free. Check the seal on the brake cables. GRACE MX II Operating instructions Page | 103... -
Page 22: Checking The Spring Fork (Rockshox Domain, Rockshox Sektor)
Brake pads and discs wear due to friction. The more often you ride in a hilly environment or through rain or dirt, the higher the wear. The braking system on the GRACE MX II has a fully-automatic pad synchronisation system. This system balances the wear on the brake pads so that the pressure point of the brake is always constant. -

Page 40: Transport
Transporting the GRACE MX II battery in a passenger aeroplane is not permitted. Transporting the GRACE MX II with its battery installed on a car with a roof or tailgate carrier is not permitted. Remove the battery before transport. The weight of the bike places special requirements on a car roof or tailgate support. -
Page 41: Wear Parts, Maintenance, Vehicle Inspection After An Accident
The brake pads are subject to function-related wear which is heavily dependent on how the GRACE MX II is used. When riding along tracks with heavy drops or when using it for bike sports, it may be necessary to replace the brake pads at shorter intervals. It is therefore essential that you check the wear on your brake pads regularly. -
Page 42: Replacing The Belt Pulleys When They Are Damaged
The chain is susceptible to function-related wear which depends on maintenance, repair and the how the GRACE MX II is used (performance, dirt, salt, riding in rain, etc.). The service life can be extended by regularly cleaning and lubrication. However, the chain will need to be replaced when it reaches its wear limit. -

(distance, riding in rain, dirt, salt). 8.12. Frame paint and coating The coatings on the parts of your GRACE MX II protects them from corrosion. Regularly check all paint surfaces for damage and touch up these surfaces right away. This also preserves the look of your bike. -
Page 44: Maintenance
Your GRACE dealer knows your bike very well and has the right tools to maintain your GRACE bike. After a crash or an accident on your GRACE MX II, you must take your bike to a specialist dealer for a thorough inspection. -
