4.4.
Switch the drive system on/off
Briefly press on one of the two top buttons. Activation is acknowledged by the system with
an acoustic signal. A self-test is conducted which ends with a count down on the
tachometer.
The drive system is activated as soon as you press down on the pedals. The level of
assistance provided is based on the settings in the on-board computer. Once you
stop pressing down on the pedals while riding, or once you have reached the
maximum assisted speed, the drive system will de-activate assistance mode.
Assistance mode is automatically re-activated once the speed falls below the
maximum assisted speed and you apply force to the pedals.
The drive system can be switched off by pressing the -
button briefly - this is also
acknowledged with an acoustic signal.
4.5.
Choose an assistance level
The GRACE EASY only provides assistance when you apply force to the pedals. Once you stop
applying force, the electric motor switches off. The pedal power assistance will also switch
off if you exceed the maximum assisted speed.
If pedal power assistance is switched on when riding over a smooth or slippery road
surface, the rear wheel may spin or slip when accelerating. Risk of accident!
Always switch off pedal power assistance on smooth or slippery road surfaces.
The assistance level allows you to select the output the electric drive should provide to assist
your pedal power. The higher the assistance level, the less force you need to exert to
maintain a specific speed. You can choose between four assistance levels.
The electronic components are integrated via interfaces. Interfering with electronic
components or software improperly may under certain circumstances cause faults
in systems which were not modified. These kinds of functional faults can put the
operational reliability of your GRACE EASY at risk and thus put your own safety at
considerable risk. For this reason, always have a qualified workshop carry out all
work and modifications on electronic components.
