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.

Overview

EN 15194:2017+A1:2023 - published by CEN - is the European standard for EPAC bicycles (Electrically Power Assisted Cycles). It applies to EPACs for private and commercial use (except EPACs intended for hire from unattended stations) and sets safety, performance and testing requirements for e-bikes intended for public roads. The standard covers EPACs with a maximum continuous rated motor power of 0.25 kW where assistance is progressively reduced and cut off by 25 km/h (or earlier if pedalling stops). It applies to systems up to 48 V DC or with integrated battery chargers having a 230 V AC input and to bicycles with a saddle height of 635 mm or more.

Key Topics and Requirements

• Scope & safety philosophy: Addresses significant hazards, foreseeable misuse, and safety-related protective measures for EPACs.
• Electrical systems: Requirements and test methods for engine power management, electrical circuits, batteries, chargers, wiring, moisture resistance, and anti‑tampering measures.
• Power limits & control: Defines maximum continuous power (0.25 kW), speed cut-off behaviour at 25 km/h, start‑up assistance mode and power management testing (including measurement at the motor shaft).
• Electromagnetic compatibility (EMC): Annex B sets emission and immunity tests for EPACs and separate electrical/electronic sub-assemblies (ESA), with measurement methods and test conditions.
• Mechanical safety: Detailed requirements for brakes, steering, frames, forks, wheels/tyres, saddles/seat posts, luggage carriers, lighting/reflectors, and thermal hazards.
• Performance and testing: Road-test procedures for fully assembled EPACs, mechanical strength tests, and specific test methods for components and assemblies.
• Marking, labelling & instructions: Mandatory durability tests for marking and required user instructions for safe use and maintenance.
• Exclusions & applicability: Not applicable to EPACs manufactured before the standard’s publication; excludes certain hire‑station EPACs.

Applications and Who Uses It

• EPAC and e-bike manufacturers and component suppliers (motors, batteries, chargers, controllers)
• Design engineers and product safety teams implementing compliant electrical and mechanical designs
• Test laboratories and certification bodies performing conformity and EMC testing
• Retailers, fleet operators and commercial e-bike providers seeking regulatory compliance and safe operation
• Regulators and standards committees using the standard to align national rules and market access in the EU

Related Standards

• National adoptions of EN 15194 by CEN members; consult your national standards body for implementing documents.
• For EMC details, see the normative Annex B within EN 15194 and applicable EMC standards referenced therein.

EN 15194:2017+A1:2023 is essential for ensuring safe, road‑legal EPAC design, consistent testing and market access across Europe.

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.
