Simple Maintenance and Service Activities
Maintenance
The V-belt is easily replaced. This maintenance operation can be performed by users with
manual skills.
If you have difficulties obtaining a replacement V-ribbed belt for your ergo_bike,
you can order one directly from the manufacturer: daum electronic GmbH.
The driving surfaces of the drive and the V-belt pulley are covered with a rubber layer by
the manufacturer.
This favors the development of an optimal fitting of the V-belt into the grooves of the driving
pulley during the first 500 - 1000 kilometers.
During this fitting-in process, the belt will loose the excess rubber, which will be visible in the form of
black powder deposits. You can remove this deposit using a small brush or a vacuum cleaner
(particularly for the transparent ergo_bike models).
