Introduction
This document gives requirements and test methods for mechanical and functional aspects for cargo
trailers.
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 cargo trailers of a type which are excluded from
type approval by Regulation (EU) No. 168/2013.
Because of the diversity of geometries and solutions of trailers not all requirements and test methods in
this document may apply to every trailer.

For the purposes of this document, the terms and definitions given in prEN 17860-1:2022 and the
following apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp/
— IEC Electropedia: available at https://www.electropedia.org/
3.1
cargo trailer
single or multi axle trailer with or without electrical assistance for the conveyance of loads connected to
a cycle with device for connection behind a cycle
Note 1 to entry: For electrically assistance, please see definition of electrically power assisted cargo trailer.
3.2
connecting device
part of the cargo trailer that is used for coupling to the towing cycle
3.3
overrun brake (system)
brake which is actuated by the decrease in relative distance between cycle and cargo trailer
3.4
drawbar
part of the cargo trailer that is used to connect the cargo trailer with the towing cycle and is used to steer
the cargo trailer while maintaining specific distance from the towing cycle
3.5
secondary safety device
safety device which prevents a complete disconnection of the cargo trailer connected to a cycle or an
electrical safety device which deaccelerates the cargo trailer in case it is getting disconnected from a cycle
3.6
electrically power assisted cargo trailer
EPACT
cargo trailer, equipped with auxiliary electric motor, whereas the electric motor only propels by the
movement of the towing cycle, except in the hand-cart assistance mode
4 Cargo trailer cycle combination
The recommended maximum gross vehicle weight of the cargo trailer is:
— 600 kg when the trailer is pulled by a multi track carrier cycle;
8

---------------------- Page: 10 ----------------------
oSIST prEN 17860-7:2023

— 350 kg when the trailer is pulled by a bicycle, EPAC or single track carrier cycle.
5 General vehicle requirements
5.1 Design of the surface requirements
Shall be according to prEN 17860-2:2022, 5.1.
5.2 Securing and strength of safety-relevant fasteners
Shall be according to prEN 17860-2:2022, 5.2.
5.3 Mudguards/wheel covers
5.3.1 Requirement
The requirements in accordance with EN ISO 4210-2:2023, 4.11 apply.
5.3.2 Test method
The test shall be conducted in accordance with EN ISO 4210-3:2023, 4.2.
5.4 Deflection device
Cargo trailers shall be designed in accordance with EN 15918:2011+A2:2017 such that a vertical obstacle
cannot be caught between a wheel and the body of the cargo trailer when the cargo trailer is drawn
forwards past any such obstacle. An example is shown in Figure 1.

1 deflection devices
2 vertical obstacle
3 moving direction
Figure 1 — Example of the deflection devices for single and multi axle cargo trailers

The width of cargo trailer in front of the wheels shall not be less than the distance between the tyre
centrelines and be shaped so that the cycle trailer is deflected sideways when drawn past a vertical
obstacle with a minimum height of 750 mm and diameter of 90 mm (see Figure 1).
The deflection device shall be strong enough not to collapse if a trailer with maximum payload is hitting
the obstacle.

5.5 Position of payload
The position of the transported load shall be selected such that the cargo trailer can be ridden and braked
safely in each loading and operating situation, the cyclist in the front is not hindered and vision is not
limited. A rear-view mirror on the towing cycle shall be recommended if vision to the rear is limited due
to normal positioning of the payload or the vehicle’s construction.
The manufacturer shall outline in the user manual the allowed load distribution on the cargo trailer such
that the load distribution does not result in the cargo trailer having too aft centre of gravity.
Uniform wheel load distribution and the lowest possible overall centre of gravity shall be strived for.
5.6 Recommendations for loading areas/load securing
Design recommendations can be found in prEN 17860-2:2022, Annex I Part 2.
5.7 Braking
5.7.1 General
A cargo trailer shall be equipped with at least two brake systems which are operated simultaneously. The
brake systems shall function without jamming.
The cargo trailer until total mass of 100 kg (including payload) are exempted from overrun brakes only
if the connection point to the cycle is not higher than 400 mm above the ground. Additionally, the
manufacturer shall confirm the braking performance according to the test in 5.7.2 with the lightest
possible cycle available. The manufacturer shall also recommend the cycle type (including brake type,
frame type, tire profile and empty weight of the cycle) according to the results of the braking distance
test to its customers for operations.
The requirements in accordance with Table 2 shall be met.
NOTE See EN ISO 4210-4:2023, 4.6.5.7, Point h), Test method — Simple check on the test track.
5.7.2 Hand-operated brakes
