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 EMotorbike 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 7980 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.

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.
Page 11
GRACE ONE 2013 Manual

Initial operation
Charging the battery pack
The battery packs of your GRACE ONE E-Motorbike are integrated securely inside the
frame. In the top tube there is a large lithium ion cell battery installed and two small
batteries are housed in the down tube. All of the batteries are connected in parallel.
Lithium ion batteries are not subject to any memory effect. You can re-charge them at any
time, even after short rides. Proceed as follows in order to charge the batteries:
1.
Insert the main plug of the original
charger provided. (220 V
- 240 V 50 Hz)
Open the dust cap and connect the plug
of the charger with the charging port.
To charge the batteries, use the standard charger exclusively.
Otherwise there
is a risk of explosion.
2.
The charging process will start
automatically.
3.
4.
When the LED of the charger is lit up in
green, the batteries are fully charged. The
indicator on the display will show a slight

Checking the tyre pressure
Tyres make contact between the wheels and the road. They ensure that the wheels grip
the road and that there is traction and absorb small shocks depending on the tyre
pressure.
Please note the manufacturer’s information on air pressure printed on the
side of the tyre.
Exceeding the maximum permissible air pressure when you pump your tyres
can lead to their bursting.
The GRACE ONE E-Motorbike is equipped with the following standard tyres:
SCHWALBE Crazy Bob special street legal edition (26 x 2.35)
The manufacturer recommends the following readings for operating pressure for the tyres
used:
2.0 – 2.5 bar (30 – 35 psi) for the front wheel tyres
2.0 – 2.5 bar (30 – 35 psi) for the rear wheel tyres
Please note when you are replacing tyres that you must use tyres of the same
type, dimensions and tread exclusively.
The ECE mark must be printed on the tyres!
The tyres are filled with air and the air pressure is
regulated by means of
Schrader valves.
This
can be done with track pumps or with
the
compressed air dispenser at the petrol station.

The motor
Your GRACE ONE E-Motorbike is equipped with a 1.3-kilowatt electric motor, which also
forms the hub of the rear wheel. This type of motor is also called a hub motor for that
reason.
You can request power from the motor by means of a throttle handle.
A regulator that is located in the control unit of your GRACE ONE under the top tube
regulates the power output of the motor and limits the latter when the maximum
permissible speed for this class of bicycle, which is 45 km/h, is reached.
However, you can also reach higher speeds with your GRACE ONE E-Motorbike, for
example on an incline or when you have a tailwind. Then you are depending on the
conventional chain drive alone and have no more assistance from the motor.
If your speed falls below 45 km/h, then the motor power is available to you again.

The derailleur system
A
ctivate the derailleur by means of the grip
shift
on the left handlebar grip.
Do not activate the derailleur system, when the bike is at a standstill, but
rather only during a ride when the crank is turning at the same time.
There are nine different gear ratios available.
The throttle handle
You can start your motor drive on the back wheel
of your GRACE ONE
E-Motorbike
with a rotary
motion of the throttle handle.
The further the throttle handle is rotated, the
more energy gets directed to the motor and the
greater the acceleration or the speed is.
The brakes
Page 20
62
GRACE ONE 2013 Manual
The brakes are operated by means of the brake
lever on the handlebar, whereby the left brake
lever slows
down the front wheel…
… and the right brake lever slows the rear wheel
down.
Do not fail to carry out some braking tests to familiarize yourself with the
hydraulic brake system, before you venture into road traffic with your
GRACE
ONE E-Motorbike.
If you squeeze the front wheel brake too hard, this can lead to a rollover or fall
due to the front wheel breaking loose!
The brake disks and the brake callipers of your GRACE ONE E-Motorbike can
become very hot when you are braking and
can cause burns if they are
touched.

Wearing parts, maintenance and vehicle inspection after a fall
Some parts and components on your GRACE ONE E-Motorbike are susceptible to wear
due to their function and must be monitored with particular care for that reason and
regularly maintained or replaced, where applicable. Wearing parts include the following:
Tyres
Wear to the tyres depends on how the GRACE ONE E-Motorbike is used and can be very
strongly influenced by the rider. The lifespan of a tyre is considerably shortened by sharp
braking which leads to the blocking of a tyre and reduces its life span considerably. In
addition, tyre pressure should be checked regularly and tyres should be pumped to the
level specified by the tyre manufacturer, where applicable.
Handles
Handlebars and grip coverings are susceptible to wear due to their function and must be
replaced regularly where applicable. Handles must always be firmly connected to the
handlebars.
Brake pads
Due to their function, brake pads are susceptible to wear, which is very dependent on how
the GRACE ONE E-Motorbike is used. If the GRACE ONE E-Motorbike is used for sports or
for trips on routes with steep inclines, it may be necessary to change the brake pads at
frequent intervals. Therefore, it is absolutely essential to check the state of wear of the
brake pads regularly. Have them replaced by a dealer, if necessary.
The chain
Due to its function, the chain is susceptible to wear, which is very dependent on care and
maintenance and on how the GRACE ONE E-Motorbike is used (mileage, dirt, salt and
riding in the rain, etc.). The life span of the chain can be prolonged by regular cleaning and
lubrication although it is necessary to replace it when the limit is reached.
Chain wheels, the cartridge, rear derailleur rollers and the bottom bracket
All sprockets, chain wheels and the bottom bracket are susceptible to wear due to their
function. Wear and tear on these components depends on care and maintenance and the
use of your GRACE ONE E-Motorbike (mileage, dirt, salt, trips in the rain, etc.).
Page 32
74
GRACE ONE 2013 Manual
Gear switching cables
The Bowden cables of the gears must be regularly maintained and replaced, if applicable.
This can be the case, especially if the GRACE ONE E-Motorbike is often stored outdoors
and exposed to the elements.
Lights
Flawless functioning of the lighting systems is very important for traffic safety. As lights
are susceptible to wear due to their function, they should be checked before every trip to
see how they are functioning. You should always have spare lights with you in order to be
able to replace them, if necessary.
Hydraulic oils and lubricants
Hydraulic oils and lubricants lose their effectiveness over time. Therefore, all areas to
which lubricants are applied must be cleaned regularly and re-lubricated in order to avoid
increased wear to the parts and the bearings involved.
Handlebars and seat posts
Both the handlebars and the seat post are subject to severe dynamic stresses, when the
bike is being ridden. Therefore, check them regularly for visible external damage and
replace them, where applicable. Furthermore, we recommend that these parts be
replaced every two years, if your GRACE ONE E-Motorbike is subject to heavy use.
Frame paintwork and coating
The coating on the structural elements of your GRACE ONE E-Motorbike protects them
against corrosion. Check all painted areas regularly for damage and touch them up
immediately. This also maintains the appearance of your GRACE E-Motorbike.
When you purchased your GRACE ONE E-Motorbike, you received a service
booklet from your dealer. Please
adhere without fail to the inspection
intervals entered for your safety and your enjoyment of your bike.
Page 33
GRACE ONE 2013 Manual
75
Maintenance
We recommend that your dealer inspects your bike for the first time after you have ridden
100 kilometres. Spokes, brakes, gears and bearings can shift due to settling processes
during this running-in phase. Your GRACE dealer is the one, who is most familiar with your
bike and has the appropriate tools for the maintenance of your GRACE vehicle.
Inspection of your bike after an accident or fall
After a fall or an accident on your GRACE ONE E-Motorbike, you should bring your bike to
your authorized dealer for close examination in any event.
Damage that was caused by falls or improper handling can only be repaired
by your GRACE dealer.
Changing parts
Your GRACE ONE E-Motorbike is a moped and it is therefore necessary to obtain a permit
from the German Federal Bureau of Motor Vehicles and Drivers and the Vehicle
Registration Office. There is a type approval available for the GRACE ONE.
During the approval process, certain parts were specified, whose use is approved for this
vehicle. This means that the approval only remains valid, if these precise parts of the type
