Overview
EN ISO 20957-10:2017 (ISO 20957-10:2017) covers additional safety requirements and test methods for stationary training equipment specifically for exercise bicycles with a fixed wheel or without a freewheel that have an inertia greater than 0.6 kg·m². This part is intended to be read in conjunction with ISO 20957‑1, which contains the general safety requirements for stationary training equipment. EN ISO 20957-10:2017 was endorsed by CEN as a European standard and replaces earlier editions (superseding EN 957‑10:2005).
Key Topics
The standard focuses on practical, safety-related design and verification aspects for fixed-wheel exercise bikes. Major topics include:
- Classification of equipment types within the ISO 20957 series.
- External construction and guarding of transmission elements, rotating parts, squeeze and shear points to prevent user injury.
- Temperature limits for accessible surfaces to avoid burns.
- Intrinsic loading requirements for structural elements such as seat pillars, handlebars and pedals to ensure mechanical integrity under use.
- Adjustment and insertion depth criteria for seat pillars and handlebar stems to prevent loosening or collapse.
- Pedal and crank endurance requirements to address fatigue and longevity of pedal crank assemblies.
- Stability and locking system tests to verify safe static and dynamic behaviour.
- Emergency braking system requirements and test methods, including effectiveness, actuator integrity and visibility of controls.
- Foot clearance, power display accuracy and user information: marking and instructions.
- Test methods: dimensional checks, visual examination, performance tests and specific component tests (transmission, temperature, intrinsic loading, stability, braking, pedal crank, power display, locking). A formal test report is required.
Applications
EN ISO 20957-10:2017 is primarily used by:
- Exercise bicycle manufacturers designing fixed-wheel or no-freewheel bikes to meet recognized safety criteria.
- Product designers and R&D teams to integrate safety, adjustment and braking solutions early in development.
- Test laboratories and certification bodies performing conformity and type testing against the standard’s test methods.
- Quality assurance and compliance managers ensuring products meet European/CEN-adopted safety expectations.
- Procurement specialists and facility managers specifying safe stationary training equipment for gyms, studios and rehabilitation centers.
Related Standards
- ISO 20957‑1 - General safety requirements for stationary training equipment (must be read together with Part 10).
- EN 957‑10:2005 - earlier edition superseded by EN ISO 20957‑10:2017.
- Other parts of the ISO 20957 series cover different types of stationary training equipment and collective testing guidance.
Using EN ISO 20957-10:2017 helps stakeholders ensure fixed-wheel exercise bicycles are safe, durable and testable to consistent international and European benchmarks.
