The Brakes
Rear Brakes
The rear brakes on your e-bike are EABS Brakes (Electric Absorption Braking System).
These provide a good friction-grip when they are activated. They significantly less than
standard drum brakes. Using these brakes helps to reduce the weight of the e-bike and
improve its performance.
Front Brakes
The brakes on your e-bike are drum-brakes, like those found on gas scooters and
motorcycles. They generally provide for very fine stopping and control. This is a very tested
and well-designed technology, but even so, the brakes will require servicing from time to
time, and may have to be adjusted for tension.
Unlike normal friction-grip bicycle brakes, which clamp down from the outside, the drum
brakes clamp from the inside. When the brakes are activated, tension increases and the
clamps engage. This is a very effective and reliable way to stop a vehicle.
The brakes are contained within a sealed unit, and are very finely adjusted and fitted.
The Chain and Pedals
The pedals are connected to the rear wheel. Along with the chain, they provide a human-
powered “drive train”. This is an important part of your e-bike. The pedals are not
removable and should not be removed.
Shock Absorbers
Your Vienna e-bike is equipped with Reverse Shock System shock absorbers. These
effective but simple devices absorb the energy from bumps and dips, and allow you to
have a much more comfortable ride. The Reverse Shock System is superior to normal
Monoshock shock absorbers usually found on e-bikes, and provides for a much more
comfortable ride.
While they are very resilient, please note that very sharp or large shocks, such as drops
from a height of 15 cm or more, can cause serious damage to your shock absorbers.
Replacing them is a complex and time-consuming task, so do be careful when dropping
from larger heights.
