Important to read before the rst ride
Supplemental Product Information
The most important points for you to do
1. Even if you have ridden a bicycle for years, it is important for every person to read
the general ‘Bicycle Owner’s Manual’ and the specic ‘E-Bike Owner’s Manual’
carefully before you ride on the new e-bike.
• Both manuals contain detailed information and useful suggestions about your new
bicycle.
• Make sure that you understand the proper use, maintenance and disposal of the
components of the electrical system of your new e-bike.
2. Think about safety. Your safety and that of other road users is very important.
• Check your bicycle for normal operation, loose parts and defects before riding.
If you nd any problem, visit your authorised bike shop for repairs before riding.
• Be aware that other road users (cars, vans, motorcycles) do not expect that an e-bike
can ride faster than a normal bicycle. Riding faster also increases the risk of accidents.
Distances will close much faster and braking distances will become longer.
• Do not ride abusively. Only ride in the use conditions specied for your bicycle.
Please refer to the Use conditions table in the general Bicycle Owner’s Manual.
3. The electric system of your new bicycle needs special attention.
• Do not clean your e-bike with a high-pressure washer. Any electrical system is sensitive
to moisture. High-pressure water might enter connectors or other parts of the electric
system.
• Do not allow a Li-Ion battery (separately or integrated in the downtube) to suer any
mechanical or physical impacts or make any internal modications. In an extremely
rare case, a battery that has been severely impacted or otherwise mishandled could
potentially catch re. If you suspect damage to your battery, visit your local authorised
bike shop immediately for inspection.
4. Maintain the battery as instructed in this E-Bike Owner’s Manual.
Failure to follow these instructions may result in damage to your battery and may require
battery replacement:
• Only charge the battery with the included charger.
• Charge the battery indoors or in a garage at room temperature to avoid exposure to
rain or wind.
• When you do not use the e-bike for an extended period of time, charge the battery to
80% to meet the optimum storage condition. Check the charge level again after six
months. If the remaining charge of the battery is less than 30%, charge it again to 80%.
Once charging the battery is complete, unplug the battery from the charger and unplug
the charger from the wall socket.
• Your e-bike has a built-in Li-Ion battery. Any Li-Ion battery will self-discharge over time.
If the battery is left uncharged, then stored without charging, it may discharge to such
a low state that the battery can no longer be charged and must be replaced.
• Store the e-bike in a dry, well-ventilated location. Protect the battery against moisture
and water.
• The battery can be stored at temperatures between (minimum) -20°C (-4°F) and
(maximum) +50°C (122°F). For a long battery life, however, it is best to store the battery
at room temperature of approximately 20°C (68°F).
5. Be careful when transporting an e-bike.
• An e-bike is heavier than a normal bicycle. If transporting on a vehicle, be aware of
the maximum load capacity of the vehicle’s roof, towing hitch and/or the bicycle carrier.
Refer to the manuals of the vehicle and bicycle carrier for details.
• Always respect local laws about transportation of an e-bike.
Because Li-Ion batteries of this size and power are considered ‘Dangerous goods,
class 9’ when transporting, regulations may restrict the transport of separate Li-Ion
batteries in some places. Before booking your trip, make sure to check ahead with
your airline or carrier if it is allowed to travel with your complete e-bike.
6. Obey local regulations.
In most countries, the regulations for the use of an e-bike are the same as those for a
standard bicycle. However, there may be local dierences such as where you can ride,
minimum rider age or required equipment and registration.
It is the rider’s responsibility to know the local regulations that apply to an e-bike and
to obey them.
7. Visit your bike shop on a regular basis for maintenance of your new bicycle.
Your bike shop has the right knowledge and equipment to maintain your e-bike.
If you have questions about your new e-bike, ask your local authorised bike shop.
Limited warranty
Your bicycle is covered by a Limited Warranty.
