The regulations apply to bicycles that are first used in Norway on or after 1 January 1971.

Bicycle:  A vehicle propelled by pedals or a crank, excluding vehicles used as toys.

A bicycle is also considered to be a vehicle as mentioned in the first paragraph and which is equipped with an electric auxiliary motor with a maximum nominal power of no more than 0.25 kW, where the power of the auxiliary motor is gradually reduced and ceases when the vehicle reaches a speed of 25 km/h, or earlier if the cyclist stops pedaling/cranking.  The vehicle is permitted to be propelled only by engine power up to 6 km/h.  Vehicles as mentioned in this paragraph are not considered to be motor vehicles pursuant to Section 2 of the Road Traffic Act.

A bicycle with two seats may have an electric auxiliary motor with a nominal power of no more than 0.5 kW when it can be documented that the vehicle has been assigned or loaned as an aid from the Norwegian Labour and Welfare Administration (NAV).  It is sufficient for one of the cyclists to pedal/crank for the auxiliary motor to provide power. Otherwise, the requirements in the previous paragraph apply.  Vehicles as men­tioned in this paragraph are not considered motor vehicles under Section 2 of the Road Traffic Act.

Bicycles that meet the requirements of EN 15194 are considered to meet the defini­tion in the second paragraph.

• A bicycle must be built, designed, equipped and maintained so that it can with­stand the stresses to which it is usually exposed and can be used without causing unnecessary danger or inconvenience.
• The bicycle must be clearly and permanently marked with a production serial num­ber, which must be indicated on the frame.  It must be located and constructed so that it is clearly visible and so that it cannot be easily removed or altered.

• Bicycles must have at least two separate brakes, which are such that braking can be controlled and the bicycle can be stopped safely, effectively and quickly.
• One brake should act on the front wheel and the other on the rear wheel.
• The controls (handles, pedals) must operate independently of each other.  It must be possible to use it with both hands on the handlebars.

• The bicycle must have a red reflector at the rear.  There must be a white or yellow reflector on both sides of the pedals.  When using a bicycle equipped with click-in pedals on which reflectors cannot be mounted, the bicycle must have reflectors on the pedal arms.  The reflectors must be of an approved type.
• Bicycles used in the dark or in poor visibility on a road or area with regular traffic must have a front light that gives yellow or white light and/or a multi-function light that can give flashing or steady white light.  Bicycles must have a rear light that gives red light and/or a rear light that gives flashing red light.
• The lights must be attached to the bicycle.
• The lights must be clearly visible at a distance of 300 meters.  Lights that provide flashing light must have a flashing rate of at least 120 flashes per minute.

Bicycles must have a signal bell.  Other warning devices are prohibited.

These regulations enter into force on 1 April 1990.
