Safety Safety Requirements for the rider If there are no legal requirements for riders of electrically power-assisted cycles, we recommend that the rider should be a minimum 14 years of age and have experience with muscle-powered bicycles. The rider's physical and mental abilities must be adequate to use a muscle-powered bicycle.
Safety Proper use The bicycle is designed to support a maximum speed of 25 km/h. The bicycle may only be used in a perfect, fully functional condition. National requirements may apply to the bicycle which differ from the standard equipment. For riding on public roads, some special regulations apply in relation to the riding light, reflectors and other components.
Safety • when the electrical drive has been manipulated • when the permitted gross load weight is exceeded • riding with a damaged or incomplete bicycle • riding over steps • riding through deep water • lending the bicycle to untrained riders •...
Safety Duty to take care The safety of the bicycle can only be assured if all the necessary measures are taken. 2.6.1 Rider The rider: • receives instruction before the first ride. They can clarify any questions relating to the operating instructions with the operator or specialist dealer.

Page 28
Description Dunlop valve The rider can easily exchange the valve and quickly release the air. The air pressure cannot be measured with this valve. Presta valve The Presta valve requires a smaller hole in the rim, which is why it is especially suitable for the narrow rims of racing bicycles.
Description 3.3.2 Suspension Both forks and suspension forks are fitted in this model series. A suspension fork is based either on a steel spring or air suspension. Unlike a rigid fork, a suspension fork has two functions which improve floor contact and comfort: suspension and damping.
Description Dampers which dampen compressive deflection movements, i.e. a compression load, are called compression dampers or compression dashpots. Dampers which dampen rebound deflection movements, i.e. a rebound load, are called rebound dampers or dashpots. 3.3.3 Suspension fork structure Figure 6: Example showing Suntour fork: The stem and handlebars are fastened to the fork steerer (1).
Description 3.3.3.1 Air suspension fork structure The vehicle's fork features both air suspension and a compression damper plus a rebound damper in some cases.

Description 3.5.2 Rechargeable battery Figure 12: Rechargeable battery, view of charging port side Charging port On-Off button Battery level indicator (battery) The lithium ion battery has an internal electronic protection circuit. This is matched to the charger and bicycle motor. The battery temperature is monitored at all times.
Page 37
Description The battery's service life can be extended if it is well maintained and, above all, stored at the correct temperatures. The charging capacity will decrease with age, even if the battery is maintained properly. If the operating time is severely shortened after charging, this is a sign that battery has reached the end of its useful life.

Before the first ride Adjusting the suspension Crash caused by incorrectly set suspension CAUTION If the suspension is adjusted incorrectly, the fork may become damaged, so that problems may occur when steering. This will cause a crash with injuries. Never ride the pedelec without air in the air suspension fork.
Before the first ride 6.4.1.1 Adjusting the steel suspension fork negative deflection Alternative You can adjust the fork by tensioning the spring to the rider's weight and their preferred riding style. It is not the coil spring hardness which is adjusted; it is its pre- tensioning.
Before the first ride 6.4.1.2 Adjusting the air suspension fork negative deflection Alternative Riding without filling pressure will destroy the wheel NOTICE suspension, the frame and the air suspension elements. Never ride without filling pressure in the air suspension elements. A normal air pump cannot build up the required NOTICE pressure with sufficient sensitivity.
Before the first ride The air valve is located under a screw cap on the head of the left shock absorber. Unscrew and remove the screw cap. Adjust the air pressure as an initial value using a high-pressure damper pump and based on the tyre pressure table on the fork and the rider's weight.
