68. Bicycle
A bicycle is a vehicle with two or more wheels that is primarily propelled by the rider using pedals or hand cranks. Bicycles are used for transport, recreation, sport and the carriage of small loads or passengers when appropriately equipped.
Some bicycles have an electric motor that assists the rider while pedalling. Whether an electrically assisted bicycle remains legally classified as a bicycle depends on its motor power, assistance speed and local regulations. Cyclists must follow the traffic rules, signs, signals and road-use requirements that apply to bicycles.

What is a bicycle?
A bicycle is a wheeled vehicle primarily propelled by the rider using pedals or hand cranks.
Is an electric bicycle still a bicycle?
It can be. Electrically assisted bicycles that remain within specified power and assistance-speed limits are commonly treated as bicycles. Faster or more powerful vehicles may be classified differently.
Where should cyclists ride?
Cyclists should use cycle paths, cycle lanes or the roadway according to the local traffic rules and signs. The required position varies between countries and road types.
Must cyclists use a cycle path?
This depends on the country and type of cycle facility. Some cycle paths are compulsory, while others are optional.
Do bicycles need lights?
Yes, when required by local law. Bicycles commonly need a white or yellow light at the front and a red light at the rear during darkness or poor visibility.
Do bicycles need brakes?
Yes. A bicycle used on public roads must have an effective braking system appropriate to its design and local technical requirements.
Is a bicycle helmet compulsory?
This varies between countries. Some require helmets for all cyclists or particular age groups, while others recommend helmets without making them compulsory.
Can a bicycle carry a passenger?
Yes, where the bicycle is appropriately equipped and local law permits it. A passenger should use a proper seat and any other required safety equipment.
Can cyclists ride side by side?
This depends on local law and the road conditions. Many countries allow two cyclists to ride beside each other in certain circumstances but require single-file riding when necessary for safety or traffic flow.
Is someone walking a bicycle still a cyclist?
In many traffic systems, a person who dismounts and walks the bicycle by hand is treated as a pedestrian. The exact legal definition depends on local law.
