Your GRACE ONE E-Motorbike
The GRACE ONE is the first E-Motorbike that has been authorized for road use worldwide.
It is equipped with a 1.3 kW motor with a speed of up to 45 km/h and has a range* of up
to 60 km.
In that way, the low weight and modern, high-performance lithium ion batteries make the
GRACE ONE E-Motorbike into an ecologically groundbreaking and efficient means of
transportation.
You can operate your GRACE ONE E-Motorbike independently with a motor drive or by
pedalling or you can choose to use a combination of the two drives.
The battery packs, which were developed exclusively for GRACE, are optimally suited to
the frame and provide the highest energy density with the least use of space.
The GRACE ONE E-Motorbike can be connected at any time to the automatic chargers
completely independently of the state of charge of the batteries.

Before the first use
As a moped, your GRACE ONE E-Motorbike is subject to the country-specific traffic
regulations. Please inform yourself about the guidelines that govern the equipment of
mopeds for use on the roads.
Helmets are required for riders of mopeds. Apart from the requirement of wearing a
safety helmet, it is also necessary to have an insurance sticker on the GRACE ONE E-
Motorbike and to be the holder of a class M driver’s licence.
We recommend that you try out your GRACE ONE in a suitable low-traffic location before
you venture into road traffic with it.
Please note that when you are operating the bike with the motor drive exclusively or if
you are using the motor and the pedals, the highest prescribed speed for mopeds, which
is 45 km/h, must not be exceeded.
Your GRACE ONE E-Motorbike will be delivered without installation of the rear-view
mirror or reflectors. In order to go out in road traffic, the rear-view mirror and the side
reflectors must be installed. For this, please follow the assembly instructions on pages 79-
80 in this manual.
In order to go out in road traffic, the rear-view mirror and the side
reflectors
must be installed.
Modifications of your GRACE ONE E-Motorbike, which result in an increase in
motor power and
speed, compromise your driving safety and can lead to the
loss of your driver’s licence and insurance coverage.
Please lift your GRACE ONE slightly, when you set it on the double kickstand.
To do this, grip the bike with one hand in the middle of the
handlebar and
place the other hand under the seat.
In this way, you will avoid damage to the stand.

Safety information

GRACE ONE 2013 Manual
51
Always check that the lights and the horn are working before using your bike.
Wear safety helmet when you ride the GRACE ONE E-Motorbike. We also
recommend that you wear safety goggles.
Make sure that you avoid the use of loose leg wear. In that way, you can
prevent clothing from being caught in the chain or between the spokes.
Check all wearing parts regularly. These include, but are not limited to the
drive chain, lights, brake pads, brake disks, seals, the cartridge and tyres.
Check your GRACE ONE regularly for loose spokes as they can lead to
instability at high speeds.
Modifications of your GRACE ONE E-Motorbike, which result in an increase in
motor power and speed, compromise your driving safety and can lead to the
loss of your driver’s licence and insurance coverage.
Please note that the E-Bike for safety reasons only responds to the throttle
operation when the rear wheel will be moved contemporaneously.
To save energy the GRACE ONE turns off automatically when not in use after
10 minutes.
Even when switched off electrical currents can still be in the system. If you
need to separate electrical connections please make always sure to
disconnect and to connect the contacts cleanly.
To avoid short circuits in
the system please to not touch the frame or not
foreseen contacts.

Important tips and instructions for handling lithium ion batteries
If you don’t wish to use your GRACE ONE for an extended period of time (> 1
month), make sure that the battery voltage is not below 44 volts.
In this way,
you can extend the length of the life span of your battery pack.
You can read
the battery voltage off the display (page 63).
Lithium ion batteries have no memory effect, therefore you can charge your
GRACE ONE
at any time irrespective of the state of charge of the batteries.
However, we recommend that you use up the battery capacity fully at
regular
intervals to achieve the best possible life span.
If your GRACE ONE cannot be switched off as usual, there could be a defect in
the controls. I
n this event, contact your GRACE dealer immediately in order to
avoid long-term damage to the batteries.
