SAFETY PRECAUTIONS AND USER INSTRUCTIONS
Great advice for riding in complete safety
Always carry out a complete check of the bicycle before
riding. Please thoroughly read the safety section I 4/
Always wear a helmet when you are riding to protect your head
in a fall.
Ride in the same direction as traffic, never against the flow
Never attach yourself to a car or any other vehicle
Check your speed, avoid big differences
Please avoid riding two on a bike or carrying heavy or bulky luggage. This may
obstruct your visibility or limit your control, and can lead to a fall or losing
control of the bicycle.
If you are riding at night or in bad weather :
Wear reflective and clear clothing and equip your bicycle with front and rear
lighting: lighting and red reflectors at the rear and lights and yellow or white
reflectors at the front as well as side reflectors on the wheels. Ensure your bike is
fitted with reflectors. If you are surprised by rain, remember that breaking
distances increase during rain and visibility and adherence are reduced.
Lighting might be compulsory for riding at dusk, at night or at dawn,
please refer to your local traffic rules.
NB: A person must not ride a bicycle on a road, during the hours of darkness unless the
bicycle displays a white light that is clearly visible for a reasonable distance from the front of
the bicycle and displays (i) a red light that is clearly visible for a reasonable distance from the
rear of the bicycle; or (ii) a red reflector that is clearly visible for a reasonable distance from
the rear of the bicycle when light is projected onto the reflector. No bicycle shall show any
light other than a red light to the rear.
Access to pathways, responsible riding and code of good riding.
Do not consider access to pathways guaranteed. Your behavior on your next ride
will influence accessibility to pathways for others in the years to come. Limit
skidding, avoid muddy areas and remain courteous with walkers.
