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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 83, Sports and other recreational facilities and
equipment.
This third edition cancels and replaces the second edition (ISO 20957-10:2017), which has been technically
revised.
The main changes are as follows:
— introduction added;
— formulation aligned with ISO 20957-1:2024;
— Clause 2 updated;
— Clause 3 modified to remove unused terms and definitions;
— “intrinsic loading” renamed to “loading”;
— Annex ZA added.

DRAFT International Standard ISO/DIS 20957-10:2025(en)
Stationary training equipment —
Part 10:
Exercise bicycles with a fixed wheel or without freewheel —
Additional specific safety requirements and test methods
1 Scope
This document specifies safety requirements for exercise bicycles with a fixed wheel or without freewheel
that have an inertia of >0,6 kg·m . The requirements are in addition to the general safety requirements of
ISO 20957-1, with which ISO 20957-10 is intended to be read in conjunction.
Any attachment provided with the exercise bicycle with a fixed wheel or without a freewheel for the
performance of additional exercises is subject to the requirements of ISO 20957-1.
