Installing the drive belt under tension by turning the crankset
To rule out the possibility of the belt skipping on the rear belt pulley, a guide
is installed on the dropout of your smart ebike. This ensures that the belt
always remains meshed with the belt pulley. The guide can be moved in the
slot in the right dropout after slackening the mounting bolt. In normal
operation, the distance between the belt and the guide is 1 – 1.5 mm. The bolt
is tightened with a size 5 Allen wrench and a torque of 6 Nm.
The disc brakes installed on the smart ebike use a low-viscosity mineral oil as brake fluid which, compared to DOT
brake fluid (as used in cars, motorcycles and other disc brakes for bicycles) is not irritant towards skin and eyes.
And in contrast to DOT brake fluid, this mineral oil is not hygroscopic. Therefore it does not tend to absorb moisture
from the environment which would reduce its boiling temperature. The brake fluid can thus be used for many years
as long as the brake system is leaktight and correctly filled.
When filling the disc brake system on your smart ebike, you should only use the mineral oil offered by the brake
manufacturer (“Magura Royal Blood”). Oils from other manufacturers and DOT brake fluid could cause damage to
the seals and lead to failure of the brakes.
Brakes which have been filled even once with the wrong medium, i.e. with DOT brake fluid, cannot be repaired. They
must be replaced completely.
A. Removing the belt guard (only on models with belt guard)
Undo the two rear bolts of the kickstand plate using a size 5 Allen wrench.
Undo the bolt on the mounting bracket of the belt guard on the rear stay using
a T25 angled Torx wrench.
Undo the bolt on the battery nest using a T25 Torx wrench.
