Maintenance

Maintenance

In this section you will find a break down of adjustments and replaceable parts. To keep your eBike
performing at its best you will need to regularly check these parts. Always use genuine replacement
parts.

General maintenance

•

Check the pressure and profile of the tyres.

•

Check the brakes for wear and adjust or replace them if necessary.

•

Check the wheels for buckles or damaged spokes and have them repaired immediately by a
qualified bike repair specialist.

Cleaning

Clean your bike by removing dirt with a soft bristled brush and then washing with warm water.
Regular cleaning of your bike will lengthen its lifespan. Be careful not to use too much water near the
battery. After cleaning, dry your bike using a soft cloth. Only wash the belt drive with water.

Never use a pressure washer, it could damage the electrics on your eBike.

Make sure that the battery is removed from the bike before fitting any parts.
