    1. Your GRACE EASY The GRACE EASY is a member of the class of electric power-assisted motorcycles, also known as 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.

    When wanting to use a different model of tyre than the Continental EcoContact on your GRACE EASY, also make sure that it has reflective strips on the sides of the tyres as well. Alternatively, in Germany, you can attach two spoke reflectors per wheel as per the German Traffic Registration Regulations (StVZO).

    When this idle motion is overcome with a small amount of handforce the brake will apply, the pressure point is reached. If the brake is properly adjusted and vented, applying a greater handforce will result in a higher braking performance while moving the brake lever a shorter distance. Page | 88 GRACE EASY Manual...

  • Page 23: Checking The Suspension Forks (Optional Accessory)

    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 EASY 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 31: Belt Drive

    4.11. Belt drive The GRACE EASY is fitted with an innovative drive belt reinforced with carbon fibre. When installed properly, the Gates carbon drive is almost completely maintenance-free - it requires no lubrication or re-tightening. The carbon fibres in the belt can absorb high tensile forces but are sensitive to bending loads, notching, shear forces, and blows.

  • Page 32: Gear Change

    4.12. Gear change A gearbox with 3 gears is fitted into the drive on the GRACE EASY. You switch gears using the shifter on the handlebars. You can see the gear you are currently in (in red) from the gear indicator on the shifter.

  • Page 54: Wear Parts

    The wear parts include: 9.1. Tyres Tyres wear according to how the GRACE EASY is used and can vary considerably from one rider to the next. Heavy braking which causes the wheel to lock up reduces the service life of the tyre considerably.

  • Page 55: Handlebar Grips

    The brake pads are subject to function-related wear which is heavily dependent on how the GRACE EASY 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 56: Chain (Easy 1X10)

    Due to its function, the chain is susceptible to wear, which is very dependent on care and maintenance and on how the GRACE EASY is used (mileage, dirt, salt and riding in the rain, etc.). The life span of the chain can be prolonged by regular cleaning and lubrication although it is necessary to replace it when the limit is reached.
