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.
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.
Switching the bike on and off 1. Press the green ON button and hold the key card above the stem while you are doing so. 2.

To switch the bike off, keep pressing the red OFF button. 4. The Grace One E-Motorbike is switched off if the display light has gone out.
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.
Setting the seat height 1. To set the seat height, loosen the two Allen screws of the seat post clamp. 2. Adjust the seat height so that the upper edge of the seat is approximately at the level of your hip bone, when you are standing next to your GRACE ONE. Within the adjustment range of the seat post, there are technical components such as cables and batteries.

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.
The cockpit The stem of your GRACE ONE E-Motorbike forms the connection between the handlebars and the steerer tube. The cockpit, the front lights and the on-board computer are all integrated into the stem. The operating elements for the on-board computer are located on the left hand side at the stem. The headlamp on the top is the low beam light and the lower headlamp is the high beam. Low beam light High beam light Activate the button with the light symbol on the right side of the stem.
The derailleur system Activate 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 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.

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.
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.
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.
