WHAT IS ISO 4210?

ISO 4210 is an international Standard that establishes safety requirements and specifications for the design, manufacturing, and testing of bicycles. The standard ensures that bicycles are built with high safety standards to protect users during their usage.

It covers various aspects of bicycles, including material strength, essential components like brakes, wheels, steering system, and frame, as well as testing methods to evaluate safety and performance. ISO 4210 is a reference document for the bicycle industry, used by manufacturers, importers, retailers, and certification organizations to ensure compliance with safety standards.

WHAT DOES ISO 4210 MEASURE?

ISO 4210 primarily measures the safety and performance aspects of bicycles. For example, ISO 4210-1:2023 specifies terms and definitions related to safety and performance requirements for bicycles, focusing on factors like saddle height and testing procedures. ISO 4210-2:2023 extends these measures to specific types of bicycles, including city, trekking, mountain, and racing bikes, ensuring that they meet standardized safety and performance requirements. These measurements play a crucial role in guaranteeing the quality, reliability, and safety of bicycles in various categories.

ISO 4210 – TEST METHODS

Performing an ISO 4210 test involves a rigorous evaluation of bicycles to ensure compliance with safety and performance standards. While the specific procedures may vary depending on the part being tested, such as the frame and fork, the general process adheres to ISO 4210 guidelines. Test methods often involve assessing factors like strength, durability, and overall performance. These tests are designed to guarantee the resistance and durability of individual parts and the bicycle as a whole.

HOW IS ISO 4210 DIVIDED?

ISO 4210 is divided into nine different parts. Each part covers a different aspects of bicycle safety and provide specific requirements for various components and systems. The nine parts of ISO 4210 are:

Standard	Description
ISO 4210-1	ISO 4210-1 is the first section of this International Standard and it defines the Terms and Definitions to the safety and performance requirements in the design, assembly, and testing of bicycles. NOTE: This section of ISO 4210 does not cover specialized types of bicycles like delivery bicycles, recumbent bicycles, tandems, BMX bicycles, and bicycles intended for use in extreme applications.
ISO 4210-2	ISO 4210-2 establishes the safety and performance requirements for the design, assembly, and testing of bicycles and their sub-assemblies. It also provides guidelines for the manufacturer’s instructions regarding the proper use and maintenance of these bicycles. These requirements are applicable to the following types of bicycles: Max Saddle Height for City and Trekking Bicycles: 635 or more Max Saddle Height for Young Adult Bicycles: 635 or more and less than 750 Max Saddle Height for Mountain Bicycles: 635 or more Max Saddle Height for Racing Bicycles: 635 or more
ISO 4210-3	ISO 4210-3 indicates the common test methods like: Brake tests and strength tests, Front mudguard test methods, Road test, Durability test of marking, Fatigue tests, Impact tests and Plastic material test ambient temperature.
ISO 4210-4	ISO 4210-4 indicates the braking test methods, such as: Brake lever grip dimensions, Position of applied force on brake levers, Security test on brake-block and brake-pad assemblies, Strength test on hand-operated braking system, Strength test on back-pedal braking system, Braking performance and Heat-resistance test on brakes.
ISO 4210-5	ISO 4210-5 indicates the steering test methods. For example: Freezing and Hot water tests on handlebar grips and plugs, Lateral and Forward bending test on handlebar stem, Torsional security test, Fatigue test on handlebar.
ISO 4210-6	ISO 4210-6 indicates the frame and fork test methods. Fatigue tests using various types of forces and Impact tests on the frame. Instead, for the fork, the standard includes: Tyre-clearance test, Tensile test, Static bending test, Rearward impact test, Static brake-torque test and Brake mount fatigue test.
ISO 4210-7	ISO 4210-7 indicates the wheels and rim test methods, including: Rotational accuracy, Static strength test on wheel/tyre, Front/rear wheel retention devices secured and Greenhouse effect test for composite wheels.
ISO 4210-8	ISO 4210-8 indicates the pedals and drive system test methods. In particular, the standard defines: Static strength test, Impact test and Dynamic durability test on pedal, Static strength test on drive system, Tensile strength test on drive belt and Fatigue test on crank assembly.
ISO 4210-9	ISO 4210-5 indicates the saddles and seat-post test methods, such as: Security, Static strength and fatigue tests saddle/seat post.
