The BS EN ISO 4210 series cover the safety requirements for bicycles. It provides guidelines and specifications to ensure the safety of bicycles, their components, and accessories. The scope of the BS EN ISO 4210 series covers various types of bicycles, including road bicycles, mountain bicycles, city and trekking bicycles, and electric bicycles (e-bikes).
The standards within the BS EN ISO 4210 series address different aspects of bicycle safety, including design, materials, construction, performance, and testing. They outline requirements for frame strength, braking systems, handlebars, wheels, pedals, and other components to ensure they meet specific safety criteria.
The revised versions introduce some technical improvements and clarifications.
Part 1: Technical changes including configuration of clause 3, modifications of some definitions, as well as others added
Part 2: Technically revised, with additions of new clauses, including improvement of 4.3.2 Minimum failure torque and change in minimum braking performance value in Table 2 of 4.6.8.1.3
Part 3: Technical improvement to some clauses and addition of annex c
Part 4: Technically revised: addition of test temperature requirement in 4.6.3 and 4.6.5; change in the method of calculating the braking distance in 4.6.3; addition of rolling resistance requirement and cooling requirement in 4.6.5.7; change in the test method to no cooling air of 4.7 and addition of Annex B and Annex C.
Part 5: improvement to some clauses and increase in test torque for 4.6
Part 6: improvement of some clauses and change of test equipment for 5.6
Part 7: addition of clauses, 4.5, 4.6 and 4.7
Part 8: improvement of clauses 4.1, 4.2, 4.5 and 4.6.2.
Part 9: improvement of some clauses and addition of test condition for dropper/suspension dropper seat-post in 4.5 and 4.5.3 has been changed to be only applicable if the seat-post is known to be constructed from composite materials
By following the BS EN ISO 4210 standards, bicycle manufacturers and suppliers can ensure that bicycles and their components are designed, manufactured, and tested to meet minimum safety requirements. These standards aim to enhance the overall safety of bicycles, reduce the risk of accidents and injuries, and provide consumers with reliable and high-quality products.
BS EN ISO 4210 series are designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole. Bicycles manufactured in compliance with these standards will be as safe for riders as practically possible.
