Full title and description

ISO 8098:2023 — Cycles — Safety requirements for bicycles for young children. This International Standard specifies safety and performance requirements, test methods and guidance for the design, assembly and testing of fully assembled bicycles and their sub‑assemblies intended for young children. It also gives guidance for instructions on use and care.

Abstract

ISO 8098:2023 sets out mandatory safety and performance criteria and associated test procedures for children's bicycles with a maximum saddle height greater than 435 mm and less than 635 mm. The standard covers braking, steering, frame and fork strength, wheels and tyres, pedals and crank assemblies, handlebar grips and end fittings, exposed protrusions, folding/fixing devices (where relevant), and requirements for labelling and user instructions. It excludes special stunt bicycles and points users to other standards for toys and larger bicycles where applicable.

Scope

This standard applies to fully assembled bicycles and relevant sub‑assemblies designed for young children where the maximum saddle height is more than 435 mm and less than 635 mm and the bicycle is propelled by a transmitted drive to the rear wheel. It specifies the safety and performance requirements and the test methods to verify compliance. ISO 8098:2023 is not applicable to special stunt bicycles (for example BMX). For bicycles with maximum saddle height of 435 mm or less, national ride‑on toy regulations apply; for bicycles with maximum saddle height of 635 mm or more, see the ISO 4210 series.

Key topics and requirements

• General safety and performance requirements for bicycles and sub‑assemblies (design, materials, assembly).
• Braking systems — minimum of two independently actuated brakes (one front, one rear), braking performance and strength tests, hand‑operated and back‑pedal brake requirements and adjustment criteria.
• Strength and fatigue tests — static, impact and fatigue testing for frames, forks, steering assemblies, wheels and other load‑bearing components; specified tolerances for forces, masses and dimensions in test procedures.
• Steering and handlebar requirements — steering travel limits, handlebar width and vertical clearances, handlebar grip design, end plugs and freezing/hot‑water tests for grip retention.
• Exposed protrusions and end‑protection — measures to reduce puncture and internal injury hazards from projections and fasteners.
• Wheels, tyres and rims — compatibility, inflation pressures and rim/tyre integrity requirements.
• Pedals and crank assemblies — pedal tread security and strength requirements, back‑pedal brake performance where fitted.
• Folding/locking devices — requirements to prevent unintended unlocking or interference with wheels during riding (where applicable).
• Crack detection and inspection guidance — reference to standardised methods for identifying visible cracks where required by test criteria.
• Labelling, instructions for use and maintenance — guidance on what manufacturers should supply with the bicycle to ensure safe use and care.

Typical use and users

Manufacturers and designers of children's bicycles, component suppliers, test laboratories, conformity assessment bodies, product safety engineers, retailers and importers, consumer product safety regulators, and standards committees use ISO 8098:2023 to design, test and verify that children's bicycles meet internationally accepted safety and performance criteria.

Related standards

Commonly referenced and related documents include the ISO 4210 series (bicycle safety requirements for larger/other types of bicycles), standards for non‑destructive crack detection methods (for example ISO 3452 series), national ride‑on toy regulations and relevant regional/adopted versions (EN/EN‑ISO adaptations), and applicable consumer safety or toy standards where overlap occurs.

FAQ

Q: What is this standard?

A: ISO 8098:2023 is an International Standard that specifies safety and performance requirements and test methods for bicycles intended for young children (maximum saddle height >435 mm and <635 mm).

Q: What does it cover?

A: It covers design, assembly and testing of fully assembled children's bicycles and sub‑assemblies — including braking systems, steering and handlebar requirements, frame/fork strength, wheels and tyres, pedals, exposed protrusions, folding devices (if fitted), and instructions for use and care.

Q: Who typically uses it?

A: Bicycle manufacturers, component suppliers, testing and certification laboratories, safety engineers, regulators, importers and retailers use the standard to ensure products meet accepted safety levels and to demonstrate conformity.

Q: Is it current or superseded?

A: ISO 8098:2023 is the current (fourth) edition published in January 2023 with a corrected version issued in August 2023. It supersedes ISO 8098:2014.

Q: Is it part of a series?

A: ISO 8098 is a standalone standard focused on young‑children bicycles but is related to the broader ISO bicycle safety work, including the ISO 4210 series for other bicycle categories; regional/adopted versions (EN/EN‑ISO) may also exist.
