Crash caused by brake failure
The braking effect may be unusually poor 
temporarily after cleaning, servicing or repairs. 
This may cause a crash with injuries.
 Never apply care products or oil to the brake 
discs or brake linings, or the braking surfaces 
on the rims.
 After cleaning, servicing or repair, carry out a 
few test brake applications.
Notice
Water may enter the inside of the bearings if you 
use a steam jet. This dilutes the lubricant inside, 
the friction increases and, as a result, the 
bearings are permanently damaged in the long 
term.
 Never clean the pedelec with a pressure 
washer.
Greased parts, such as the seat post, the 
handlebars or the stem, may no longer be safely 
and reliably clamped.
 Never apply grease or oil to clamping sections.

Crash caused by braking hard on rims
A rim can break and block the wheel if you brake 
hard. This may cause a crash with serious 
injuries.
Check rim wear on a regular basis.
