Overview - ISO 20957-5:2016 (stationary exercise bicycles & upper body crank equipment)

ISO 20957-5:2016 is the ISO safety standard that specifies additional specific safety requirements and test methods for stationary exercise bicycles and upper body crank training equipment. It supplements the general requirements in ISO 20957‑1, applies to equipment classed as type 5 (stationary exercise bicycles and upper-body crank devices) and covers classes S, H, I and A, B, C per ISO 20957‑1. The standard clarifies equipment classification, required protective measures, test procedures and documentation. It does not apply to roller stands.

Key topics and technical requirements

ISO 20957-5:2016 focuses on practical safety and verification items, including:

Classification and definitions (see Clause 3) - terms like crank training equipment, freewheel, seat pillar, inertia factor.
Specific safety requirements (Clause 5) covering:
- Transmission elements and rotating parts (guards and finger-probe protection)
- Temperature rise for components that may heat up
- Intrinsic loading and structural strength for seat pillars, handlebars and pedals
- Seat insertion depth, adjustment, tilting and seat systems (including recumbent designs)
- Handlebar stem adjustment and overall stability
- Additional requirements for combined or upper-body crank equipment
- Requirements for endurance, instructions for use and warning labeling
Test methods (Clause 6) for verifying safety and performance:
- Dimensional, visual and tactile checks
- Temperature-rise testing
- Finger-probe tests on cranks and moving parts
- Structural loading tests for seat, handlebar and pedal attachments
- Stability and endurance tests
- Power mode tests (constant power, heart-rate control) and power accuracy/repeatability tests for relevant classes
Reporting - required test-report content and informative annexes (e.g., inertia determination).

Applications - who uses ISO 20957-5:2016

This standard is essential for:

Fitness equipment manufacturers designing stationary bikes and upper-body crank devices
Product safety engineers and R&D teams validating mechanical safety and control systems
Test laboratories and certification bodies conducting compliance testing
Procurement teams and gym operators specifying safe equipment for commercial or institutional use
Regulatory and conformity assessment professionals harmonizing with ISO 20957‑1 requirements

Using ISO 20957-5 helps reduce user risk, streamline product approvals and demonstrate compliance with internationally recognized safety and test methods for crank-based fitness equipment.
