Introduction This European Standard has been developed in response to demand throughout Europe, and the aim has been to ensure that bicycles manufactured in compliance with it will be as safe as is practically possible. The tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, de-manding high quality throughout and consideration of safety aspects from the design stage onwards. The scope has been limited to safety considerations, and has specifically avoided standardisation of components. If the bicycle is used on public roads national regulations apply. No requirements on lighting equipment, reflectors and warning devices are specified in this European Standard, due to the existence of several different national regulations applicable in the European Countries.

4.6.2.3 Handbrake levers — Position of applied force For the purposes of all braking tests in this standard the test force shall be applied at a distance, b, which is equal to either dimension a (see Figure 4) as determined in 4.6.2.2.2 or 25 mm from the free end of the brake-lever, whichever is the greater (see Figure 7).
Key F Applied force b ≥ 25 mm Figure 7 — Position of applied force on the handbrake-lever
4.6.3 Attachment of brake assembly and cable requirements NOTE See 4.3 in relation to fasteners. Cable pinch-bolts shall not sever any of the cable strands when assembled to the manufacturer's instructions. In the event of a cable failing, no part of the brake mechanism shall inadvertently inhibit the rotation of the wheel. The cable end shall either be protected with a cap that shall withstand a removal force of 20 N or be otherwise treated to prevent unravelling.
The inner cable shall be protected from corrosion, e. g., by a suitable impervious liner to the outer casing. Also, ei-ther the inner cable shall have a low-friction coating or the outer casing shall have a low-friction lining. 4.6.4 Brake-block and brake-pad assemblies — Security test 4.6.4.1 Requirement The friction material shall be securely attached to the holder, backing-plate, or shoe and there shall be no failure of the assembly when tested by the method specified in 4.6.4.2. The brake system shall be capable of meeting the strength test specified in 4.6.6 and the braking performance requirements of 4.8.4, after completion of the test specified in 4.6.4.2. 4.6.4.2 Test method Conduct the test on a fully-assembled bicycle with the brakes adjusted to a correct position with a rider or equiva-lent mass on the saddle. The combined mass of the bicycle and rider (or equivalent mass) shall be 100 kg. Actuate each brake-lever with a force of 180 N applied at the point as specified in 4.6.2.3 or a force sufficient to bring the brake-lever into contact with the handlebar grip, whichever is the lesser. Maintain this force whilst subject-ing the bicycle to five forward and five rearward movements, each of which is not less than 75 mm distance. 4.6.5 Brake adjustment Each brake shall be capable of adjustment without the use of a tool to an efficient operating position until the fric-tion material has worn to the point of requiring replacement as recommended in the manufacturer's instructions. Also, when correctly adjusted, the friction material shall not contact anything other than the intended braking sur-face. The brake blocks of a bicycle with rod brakes shall not come into contact with the rim of the wheels when the steer-ing angle of the handlebars is set at 60°, nor shall the rods bend, or be twisted after the handlebars are reset to the central position. 4.6.6 Hand-operated braking-system — Strength test 4.6.6.1 Requirement When tested by the method described in 4.6.6.2, there shall be no failure of the braking-system or of any compo-nent thereof. 4.6.6.2 Test method Conduct the test on a fully-assembled bicycle. After it has been ensured that the braking system is adjusted ac-cording to the recommendations in the manufacturer's instructions, apply a force to the brake-lever at the point as specified in 4.6.2.3. This force shall be 450 N, or such lesser force as is required to bring: a) a brake-lever into contact with the handlebar grip or the handlebar where the manufacturer does not fit a grip; b) a brake extension-lever level with the surface of the handlebar or in contact with the handlebar. Repeat the test for a total of 10 times on each hand-brake lever or extension lever.
adjusted, and with the pedal cranks in a horizontal position, as shown in Figure 8, apply a vertically-downward force to the centre of the left-hand pedal spindle. Increase the force progressively to 1 500 N and maintain fully for 1 min.
Key 1 Chain 2 Hub sprocket 3 Left crank 4 Cycle chain-wheel and pedal crank 5 Point of force application 6 Pedal Figure 8 — Back-pedal brake test 4.6.8 Braking performance 4.6.8.1 General Braking performance is determined by the distance to stop (the braking distance). Two test methods are specified and experience has shown that either method is suitable and either can be used. One test method is the track test in which braking distance is measured directly with the progressive characteristics of the brakes being self-evident. The alternative test method is the machine test in which braking force is measured and, from which, braking dis-tance is calculated. The progressive characteristics of the brake are determined by linearity measurements. A final, simple track test checks for smooth, safe, stopping characteristics. Whichever method is used there shall be compliance with 4.6.8.2 and 4.6.8.3.
Conduct the braking-performance test on a fully-assembled bicycle after the brakes have been subjected to the strength test detailed in 4.6.6 and 4.6.7. Before testing the bicycle by either method, inflate the tyres and adjust the brakes all according to the manufacturer's instructions, but in the case of rim-brakes to the maximum clearance specified by the manufacturer. 4.6.8.3 Secondary brake-levers Where a bicycle is fitted with secondary brake-levers attached to handbrake-levers, bar-ends or aerodynamic ex-tensions, separate tests shall be conducted for the operation of the secondary brake-levers in addition to tests with the normal levers. 4.6.8.4 Requirements
4.6.8.4.1 Braking distance The bicycle shall fulfil the requirements shown in Table 1. Table 1 - Brake test velocities and braking distances
Condition Velocity km/h Brakes in use Braking distance m Both 7 Dry 25 Rear only 15 Both 5 Wet 16 Rear only 10
4.6.8.4.2 Smooth, safe-stop characteristics The bicycle shall show smooth, safe stop characteristics with regard to the intended use of the bicycle and the abil-ity of the expected user of the bicycle. (i) For the track test, safe-stop characteristics are defined as stopping within the required distances without occur-rence of any of the following : a) excessive juddering; b) front wheel locking; c) bicycle overturning (rear wheel lifting uncontrollably); d) rider's loss of control; e) excessive side-skid causing the rider to put his foot to the ground to retain control. With certain types of braking system, it may not be possible to avoid entirely some skidding of the rear wheel during braking; this is considered acceptable provided that d) or e) above do not occur as a result. Back pedal-brakes shall additionally comply with linearity test of subclause 4.6.8.5.2.
