Introduction
This document gives requirements and test methods for mechanical and functional aspects for single-
track carrier cycles.
This document has been developed in response to demand throughout Europe. Its aim is to provide a
standard for the assessment of mechanical aspects for single-track carrier cycles of a type which are
excluded from type approval by Regulation (EU) No. 168/2013.
Because of the diversity of geometries and solutions of carrier cycles not all requirements and test
methods in this document may apply to every carrier cycle.
Following the completion of a risk analysis, the focus is on mechanical aspects for single-track carrier
cycles. This document is a type C standard as specified in EN ISO 12100. The machinery concerned and
the extent to which hazards, hazardous situations and hazardous events are indicated in the scope of this
document.

1 Scope
This document applies to single track carrier cycles with a maximum gross vehicle weight of 300 kg, with
with or without electric assistance
NOTE Electric assistance will be covered in a separate part of this standard series.

3 Terms and definitions
For the purposes of this document the terms and definitions given in prEN 17860-1:2022 apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 Use cases: private and commercial/professional use
The requirements in this standard refer to carrier cycles for private use. In case the manufacturer defines
the carrier cycles to be intended for commercial/professional use higher test values for dynamic tests
apply. Annex A gives the higher test values for the relevant tests.
5 General vehicle requirements
5.1 Protrusions
This requirement is intended to address the hazards associated with the users of bicycles falling on
projections or rigid components (e.g. handlebars, levers) on a bicycle, possibly causing internal injury or
skin puncture. Tubes and rigid components in the form of projections which constitute a puncture hazard
to the rider should be protected. The size and shape of the end protection has not been stipulated, but an
adequate shape shall be given to avoid puncturing of the body. Screw threads which constitute a puncture
hazard shall be limited to a protrusion length of one major diameter of the screw beyond the internally
threaded mating part.
NOTE Handlebar ends are covered in prEN ISO 4210-2:2021.
