This European Standard is intended to cover all common significant hazards, hazardous situations and events (see Clause 4) of electrically power assisted bicycles, when used as intended and under condition of misuse that are reasonably foreseeable by the manufacturer.
This European Standard is intended to cover electrically power assisted bicycles of a type which have a maximum continuous rated power of 0,25 kW, of which the output is progressively reduced and finally cut off as the EPAC reaches a speed of 25 km/h, or sooner, if the cyclist stops pedalling.
This European Standard specifies requirements and test methods for engine power management systems, electrical circuits including the charging system for the design and assembly of electrically power assisted bicycles and sub-assemblies for systems having a rated voltage up to and including 48 V d.c. or integrated battery charger with a nominal 230 V a.c. input.
This European Standard specifies safety and safety related performance requirements for the design, assembly, and testing of EPAC bicycles and subassemblies intended for use on public roads, and lays down guidelines for instructions on the use and care of such bicycles.
This European Standard applies to EPAC bicycles that have a maximum saddle height of 635 mm or more and that are intended for use on public roads.
This European Standard is not applicable to EPACs which are manufactured before the date of its publication as EN.

Introduction
This European Standard gives requirements for electrically power assisted cycles (EPAC).
This European Standard 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 standard is on EPAC as bicycles for city and
trekking. Folding bicycles are included.
This document is a type C standard as stated in EN ISO 12100. 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
standards, for machines that have been designed and built according to the provisions of this type C
standard.
In real life situation an EPAC can fall over to the side causing the battery holder to break without
damage to the battery case itself. While the standard contains a strength test for the battery an
additional test is required for the situation described. This will be considered at the next revision. The
battery holder needs to withstand this realistic and typical situation. Risk assessment carried out by the
manufacturer should identify suitable measures to deal with this situation until it can be dealt with in
the standard.
1 Scope
This European Standard applies to EPAC bicycles for private and commercial use with exception of
EPAC intended for hire from unattended station.
This European Standard is intended to cover all common significant hazards, hazardous situations and
events (see Clause 4) of electrically power assisted bicycles, when used as intended and under condition
of misuse that are reasonably foreseeable by the manufacturer.
This European Standard is intended to cover electrically power assisted bicycles of a type which have a
maximum continuous rated power of 0,25 kW, of which the output is progressively reduced and finally
cut off as the EPAC reaches a speed of 25 km/h, or sooner, if the cyclist stops pedalling.
This European Standard specifies requirements and test methods for engine power management
systems, electrical circuits including the charging system for the design and assembly of electrically
power assisted bicycles and sub-assemblies for systems having a rated voltage up to and including
48 V d.c. or integrated battery charger with a nominal 230 V a.c. input.
This European Standard specifies safety and safety related performance requirements for the design,
assembly, and testing of EPAC bicycles and subassemblies intended for use on public roads, and lays
down guidelines for instructions on the use and care of such bicycles.
This European Standard applies to EPAC bicycles that have a maximum saddle height of 635 mm or
more and that are intended for use on public roads.
This European Standard is not applicable to EPACs which are manufactured before the date of its
publication as EN.

separate technical ESA unit that does not differ from other units in its essential design and construction
aspects
Note 1 to entry: For example:
— the function performed by the ESA;
— the general layout of the electronic and/or electrical components;
— direct vehicle control performed by the rider acting on the steering, the brakes and the accelerator
control.
3.33
exposed protrusion
protrusion which through its location and rigidity could present a hazard to the rider either through
heavy contact with it in normal use or should the rider fall onto it in an accident
3.34
fork steerer
fork stem
part of a fork that rotates about the steering axis of a bicycle frame head tube
Note1 to entry: It is normally connected to the fork crown or directly to the fork legs, and is normally the point
of connection between the fork and the handlebar stem.
3.35
fracture
unintentional separation into two or more parts
3.36
full discharge of the battery
point at which the battery does not deliver any power/energy to the motor, according to the battery
manufacturer’s specifications
Note1 to entry: It is recommended that the battery cells be never fully discharged and residual current of
battery be used by other devices.
3.37
highest gear
gear ratio which gives the greatest distance travelled for one rotation of the cranks
3.38
hub-brake
brake which acts directly on the wheel-hub
3.39

3.41
electrical control system
electronic and/or electrical component, or an assembly of components provided for installation into a
vehicle, together with all electrical connections and associated wiring for the engine electrical power
assistance
3.42
lowest gear
gear ratio which gives the shortest distance travelled for one rotation of the cranks
3.43
maximum inflation pressure
maximum tyre pressure recommended by the tyre or rim manufacturer for a safe and efficient
performance
Note 1 to entry: If the rim and tyre both indicate a maximum inflation pressure, the maximum inflation
pressure is the lowest of the two pressures indicated.
3.44
maximum saddle height
vertical distance from the ground to the point where the top of the seat surface is intersected by the
seat-post axis, measured with the seat in a horizontal position and with the seat-post set to the
minimum insertion-depth mark
