Overview

EN ISO 4210-7:2023 - “Cycles - Safety requirements for bicycles - Part 7: Wheel and rim test methods (ISO 4210‑7:2023)” is the CEN-adopted European version of the ISO document that specifies wheel and rim test methods used to demonstrate compliance with the wheel-related safety requirements in ISO 4210-2. This second edition (2023) supersedes EN ISO 4210-7:2014 and introduces additional test methods to cover emerging wheel technologies.

Key topics and technical requirements

This part of the ISO 4210 series defines laboratory test procedures (test methods) for wheel and rim assemblies. Principal topics include:

• Rotational accuracy - measurement of axial (lateral) and radial (concentricity) run-out for assembled wheels (tyre fitted and inflated in most cases); separate measurement details for racing wheels.
• Static strength test - static loading of the rim with prescribed forces (see Table 1) and measurement of deflection after loading and settling.
• Wheel retention test - applying a 2 300 N force to simulate removal direction and check front/rear wheel retention devices.
• Greenhouse effect test (composite wheels) - exposure of a wheel and tyre assembly in a climate chamber (pre-heated to 80 °C) for 4 hours followed by 4 hours cooling and re-measurement of rim width/conformance.
• Heat-resistance test for composite rims used with rim brakes - procedure to verify rim behaviour under brake-induced heating (measurement conditions reference 4.4).
• Impact test and overpressure test - added in the 2023 edition to address failure modes from impacts and inflation faults.
• Fatigue testing - informative Annex A provides a fatigue test for city and trekking bicycle wheels.

The standard references related parts of the series: ISO 4210-1 (vocabulary), ISO 4210-2 (requirements), ISO 4210-3 (common test methods) and ISO 4210-4 (braking tests).

Applications and who uses it

EN ISO 4210-7:2023 is intended for practical use by:

• Bicycle and wheel manufacturers for product development, design validation and type testing.
• Independent testing laboratories for certification and compliance testing of wheels and rims.
• Quality assurance teams to set production inspection and batch-testing procedures.
• Component designers and material suppliers (especially composite rim makers) to validate heat and environmental resistance.
• Regulators, procurement bodies and safety auditors assessing conformity with ISO 4210 series safety requirements.

Typical use cases: verifying wheel strength/durability, validating retention systems, evaluating composite rim performance under thermal stress, and ensuring rotational accuracy for safety and ride quality.

• ISO 4210-2: Requirements for city/trekking, young adult, mountain, racing bicycles (targeted by these test methods)

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
