Description
3.3.5 Braking system
A pedelec's brake system is primarily operated
using the brake lever on the handlebars.
• If the left brake handle is pulled, the brake on the
front wheel is applied.
• If the right brake handle is pulled, the brake on the
rear wheel is applied.
The brakes are used as an emergency stop
system and bring the bicycle to a halt quickly and
safely in the event of an emergency.
The brake is applied using the brake lever either
• with the brake lever and shift cable (mechanical
brake) or
• with the brake lever and hydraulic brake cable
(hydraulic brake).
3.3.5.1 Mechanical brake
The brake lever is connected with the brake via a
wire inside the shift cable (also known as a
Bowden cable).

3.3.5.2 Hydraulic brake
The brake fluid is in a closed hose system. If the
brake lever is pulled, the brake fluid transfers
pressure to the brake on the wheel.
