5. INTENDED USE
ASTM CATEGORY 0 - Children’s Bicycles
Designed for use on paved surfaces such as asphalt roads not used by motor vehicles and cycle paths, gravel-covered roads,
sand, or similar materials (e.g., forest roads, dirt roads) not used by motor vehicles. The wheels are constantly in contact with
the ground (without jumps, without pedalling on a single wheel, whether front or rear, and without braking that causes the rear
wheel to lift). In addition, bicycles in this category can only be used by children over the age of three and with a maximum
weight of 36 kg (80 lb).
CAUTION!
Parents/guardians are responsible for the proper functioning of the bicycle and its correct use.
