Brake system

Every pedelec has a hydraulic brake system. The
brake fluid is in a closed hose system. If the rider
pulls the brake lever, the brake fluid activates the
brake on the wheel.
The pedelec has either:
• a rim brake on the front and rear wheels
• a disc brake on the front and rear wheels or
• a rim brake on the front and rear wheels and an
additional back-pedal brake.
The mechanical brakes are used as an emergency
stop system and bring the pedelec to a halt quickly
and safely in the event of an emergency.

The rim brake stops the wheel moving when the
rider pulls the brake lever, causing two brake
linings, positioned opposite one another, to be
pressed onto the rims. The hydraulic rim brake
features a locking lever. The rim brake locking lever
is not marked with any lettering. Only a specialist
dealer may set the rim brake locking lever.
