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.

Annex A gives an overview of vehicle configurations.
Annex B provides a reading guide for the parts of this standard series.
Annex J contains a rationale explaining the choices made when developing the standard series

This document is based on 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 covered are indicated in the scope of this document.

1 Scope

This document is applicable to single track carrier cycles with or without electric assistance and a maximum gross vehicle weight of:

300 kg in case the manufacturer defines the carrier cycle to be intended for both private and commercial use; or
250 kg in case the manufacturer defines the carrier cycle to be intended for solely private use.

NOTE Requirements for electrical power assisted carrier cycles are be covered in part 5 of this standard series.
