ISO 8090:2019

Overview

ISO 8090:2019 - "Cycles - Terminology" is an international standard that defines common terms and symbols used for bicycles and two‑wheeled Electric Power Assisted Cycles (EPACs). The second edition (2019) updates and harmonizes terminology and figures to promote consistent, clear and unambiguous technical communication across manufacturers, service providers and regulatory bodies. The standard groups terms under a structured nomenclature of cycle parts and provides equivalent terms in multiple languages.

Key topics

• Scope: Terminology for bicycles and two‑wheeled EPACs; classification of parts under a formal nomenclature.
• Assemblies covered: Frame‑fork assembly; head assembly; bottom bracket and chain assembly; wheel; front and rear hubs; derailleur; brakes; saddle and pedals; other accessories; EPAC-specific terms; and symbols.
• Multilingual indexes: Official ISO terms are in English and French; the standard also supplies equivalent terms in German, Italian, Dutch, Portuguese, Japanese and Chinese for information.
• Structure: Alphabetical indexes per language and a section listing terms and symbols.
• Maintenance and provenance: Prepared by ISO/TC 149 (Cycles), SC1; this edition cancels and technically revises ISO 8090:1990.
• Access to terminological resources: ISO Online Browsing Platform (https://www.iso.org/obp) and IEC Electropedia (http://www.electropedia.org/) are referenced for standardization terminology.

Practical applications

• Ensure consistent product documentation: user manuals, assembly instructions and service guides can reference ISO‑aligned terms to reduce ambiguity.
• Improve international procurement and spare‑parts management by using standardized part names across languages.
• Support technical standards development and regulatory documents where precise cycle‑part definitions are needed.
• Aid translators, technical writers and localization teams by providing authoritative multilingual equivalents.
• Enhance safety and compliance: clearer terminology reduces misunderstandings in maintenance, labeling and warranty communications.

• Bicycle and EPAC manufacturers and OEMs
• Technical writers, documentation teams and translators
• Product designers, engineers and maintenance technicians
• Standards developers, conformity assessors and regulators
• Distributors, spare‑parts managers and procurement specialists
