Introduction
This document gives requirements for EPAC Mountain bikes.
This document has been developed in response to demand throughout Europe. Its aim is to provide a
standard for the assessment of electrically powered cycles of a type which are excluded from type
approval by Regulation (EU) No 168/2013.
Due to the limitation of the voltage to 48 V d.c., there are no special requirements applicable to the EPAC
in regard to protection against electrical hazards.
Following the completion of a risk analysis, the focus in this document is on EPAC Mountain bikes. City
and trekking EPACs are considered in EN 15194. This document is to be used in conjunction with
EN 15194:2017.
This document supplements or modifies the corresponding clauses in EN 15194:2017, so as to convert it
into for EPAC Mountain bikes. Where a particular subclause of EN 15194:2017 is not mentioned in this
document, that subclause applies. When this document states “addition”, “modification” or
“replacement”, the relevant text of EN 15194:2017 is to be adapted accordingly.
This document does not cover battery and vibration issues due to a work under development in TC 333,
not ready and not consolidated yet as “state of the art”.
This document is a type C standard as stated in EN ISO 12100:2010. The machinery concerned and the
extent to which hazards, hazardous situations and hazardous events covered are indicated in the scope
of this document.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
