GRACE EASY Manual
4.12.
Gear change
A gearbox with 3 gears is fitted into the drive on the GRACE EASY. You switch gears using the
shifter on the handlebars. You can see the gear you are currently in (in red) from the gear
indicator on the shifter.
The gear can be changed while the bike is stationary or in motion. It is easiest to
change gears while riding when applying low pedal force.

The derailleur system
Activate the derailleur by means of the grip shift on
the right handlebar grip. There are nine different
gear ratios available.
Do not activate the derailleur system, when
the bike is at a still stand, but rather only
during a ride when the crank is turning at
the same time

Braking
The GRACE EASY is fitted with hydraulic disc brakes which bring the bike to a halt quickly and
safely. Disc brakes respond more quickly than rim brakes, especially in the wet.
A hydraulic disc brake generates a high braking force even with a small handforce. To
distribute the braking force to both wheels, use both brakes at the same time. The pedal
power assistance provided by the electric motor is interrupted by braking with the front
wheel brake (or if you stop pedalling).
A sensor is built into the brake lever for the front wheel brake which switches the electric
motor to energy recuperation mode during braking. As a result, the electric motor always
applies the brakes to the rear wheel at the same time, even when the generator mode is
switched off. The braking force applied to the rear wheel depends on the speed and cannot
be adjusted. Exception: The rear wheel does not brake when the battery is fully charged.
The friction between tyres and the road surface is reduced on wet roads. In
addition, water between the brake pads and -discs reduces the effectiveness of the
brakes. The braking distance increases. Risk of accident!
