Wearing parts, maintenance and vehicle inspection after a fall

Some parts and components on your GRACE ONE E-Motorbike are susceptible to wear

due to their function and must be monitored with particular care for that reason and

regularly maintained or replaced, where applicable. Wearing parts include the following:

Tyres

Wear to the tyres depends on how the GRACE ONE E-Motorbike is used and can be very

strongly influenced by the rider. The lifespan of a tyre is considerably shortened by sharp

braking which leads to the blocking of a tyre and reduces its life span considerably. In

addition, tyre pressure should be checked regularly and tyres should be pumped to the

level specified by the tyre manufacturer, where applicable.

Handles

Handlebars and grip coverings are susceptible to wear due to their function and must be

replaced regularly where applicable. Handles must always be firmly connected to the

handlebars.

Brake pads

Due to their function, brake pads are susceptible to wear, which is very dependent on how

the GRACE ONE E-Motorbike is used. If the GRACE ONE E-Motorbike is used for sports or

for trips on routes with steep inclines, it may be necessary to change the brake pads at

frequent intervals. Therefore, it is absolutely essential to check the state of wear of the

brake pads regularly. Have them replaced by a dealer, if necessary.

The chain

Due to its function, the chain is susceptible to wear, which is very dependent on care and

maintenance and on how the GRACE ONE E-Motorbike 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.

Chain wheels, the cartridge, rear derailleur rollers and the bottom bracket

All sprockets, chain wheels and the bottom bracket are susceptible to wear due to their

function. Wear and tear on these components depends on care and maintenance and the

use of your GRACE ONE E-Motorbike (mileage, dirt, salt, trips in the rain, etc.).
