THE FINE PRINT
CLEANING THE BIKE
Use a dry or damp towel to clean the bike. Do not use steam or high-pressure cleaners. Do not immerse the bike in water.
When wiping down the battery, do not touch or short circuit the contacts on the underside. Do not immerse the battery in
water. Treat parts liable to corrosion with anti-corrosion agents. Never use cleaning, lubricating or anti-corrosion agents on
the rims as it can drastically reduce the braking performance. Always test the brakes after cleaning and before riding the bike.
IMPORTANT INFORMATION
The bike is designed for public road use. Do not ride o-road or in water. The bike is intended to be used by
only one person. The permitted gross vehicle weight (bike + rider + luggage + towed trailers) is 120kg.
The manual makes no representation about the safe use of the bike under all conditions. Have an initial inspection
carried out by a specialist cycle shop after the first 250km or four to six weeks as the spokes of the wheels will settle,
the brake cables will increase slightly and the bearings will run in during the first weeks of riding. This is important for
the acceptance of claims made under the terms of warranty.
Make sure you know and practice the rules of safe and responsible riding. Read and follow the national legal
requirements of the country where you are riding and comply with all applicable trac laws. When riding in the dark,
wear reflective clothing and use front and rear lights.
In legal terms, the electric bicycle is called EPAC (Electrically Power Assisted Cycles). This means it conforms to the
European product safety standard EN15194 standard of a maximum nominal motor power output of 250W and the
motor switches o above speeds of 25km/h. The electric motor provides assistance as long you are pedalling.
Technical detail and illustrations of this manual are subject to change.
