Cycles — Safety requirements for bicycles — Part 1: Vocabulary
This document specifies terms and definitions related to safety and performance requirements for the design, assembly, and testing of bicycles and sub-assemblies having maximum saddle height 635 mm or more. This document does not apply to specialized types of bicycle such as delivery bicycles, recumbent bicycles, tandems, BMX bicycles, and bicycles designed and equipped for use in severe applications such as sanctioned competition events, stunting, or aerobatic manoeuvres. NOTE For bicycles with a maximum saddle height of 435 mm or less, see national regulations for ride-on toys, and with a maximum saddle height of more than 435 mm and less than 635 mm, see ISO 8098.
Cycles — Exigences de sécurité pour les bicyclettes — Partie 1: Vocabulaire
Le présent document spécifie les termes et définitions relatifs aux exigences de sécurité et de performance à observer lors de la conception, de l'assemblage et des essais de bicyclettes et des sous-ensembles, ayant une hauteur de selle maximale de 635 mm ou plus. Le présent document ne s'applique pas aux types spécialisés de bicyclettes comme les bicyclettes de livraison, bicyclettes couchées, tandems, bicyclettes BMX et bicyclettes conçues et équipées pour une utilisation dans des usages sévères telles que des compétitions réglementées, cascades, ou des figures acrobatiques. NOTE Pour les bicyclettes dont la hauteur maximale de selle est inférieure ou égale à 435 mm, se reporter aux réglementations nationales sur les jouets à enfourcher, et pour une hauteur maximale de selle supérieure à 435 mm et inférieure à 635 mm, se reporter à l’ISO 8098[1].

Foreword
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
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 149, Cycles, Subcommittee SC 1, Cycles
and major sub-assemblies.
This second edition cancels and replaces the first edition (ISO 4210-1:2014), which has been technically
revised, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 333, Cycles, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
The main changes are as follows:
— the configuration of Clause 3 was systematically changed;
— some corrections according to ISO/IEC Directives Part 2 were done;
— the definitions of "racing bicycle” and "crank assembly" were modified;
— the following terms and definitions: “handlebar grips portion”, “rigid, non-welded fork”, “sag”,
“wheel and tyre assembly”, “crank assembly”, “dropper seat-post”, “seat mast cap” and “suspension
dropper seat-post” were added.
A list of all parts in the ISO 4210 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO 4210-1:2023(E)
Introduction
This document has been developed in response to demand throughout the world, and the aim has been
to ensure that bicycles manufactured in conformity with this document 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, demanding 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 standardization of
components.
If the bicycle should be used on public roads, national regulations apply.
