Standards Development

Scope

This document specifies safety requirements and test methods for single and multi-axle trailers and their connecting devices. The maximum permitted weight of such a cycle trailer, including cargo, does not exceed XX kg. (Note: Maximum permitted weight is under discussion)

This standard is not applicable to trailers for transportation of passengers, (usually children) and for types of trailers that use the fifth wheel for connecting to the front cycles.

Type of trailer Multi-track single axle Covered in this standard

Multi-track multi-axle Covered in this standard

Single track single or multi-axle Not covered in this standard

Fifth wheel trailer with the single axle or multi-axle Not covered in this standard

Usage: Cargo Covered in this standard

Usage: People/Children/Pet Not covered in this standard

Purpose

At its 12th meeting, CEN/TC 333/WG 9 Carrier Cycles recommended CEN/TC 333 to activate work items 4-7 of the standard series for Carrier Cycles. The series will consist of the following parts:

• Part 1: Carrier Cycles – Terms & definitions (prEN 17860-1)

• Part 2: Carrier Cycles – Lightweight single track carrier cycles – mechanical and functional aspects (prEN 17860-2)

• Part 3: Carrier Cycles – Lightweight multi track carrier cycles – mechanical and functional aspects (prEN 17860-3)

• Part 4: Carrier Cycles – Heavy weight carrier cycles – mechanical and functional aspects (WI 0333064)

• Part 5: Carrier Cycles –- Electrical aspects (WI 0333065)

• Part 6: Carrier Cycles – Passenger transport (WI 0333066)

• Part 7:Carrier Cycles – Trailers (WI 0333067) Carrier cycles (cargo bikes) are used in a very wide application; from private use for carrying kids and groceries, to professional use for city centre logistics.

Carrier cycle types are therefore very different, ranging from single to multi-track, with a wide range of dimensions and also a wide range in load capacity. The proposed series accommodates the different aspects to cover the wide range of product types and applications.

Part 7 of the standard series will likely give requirements and test methods covering (but not limited to): General vehicle requirements; Electrical requirements; Design of the surface; Securing and strength of safety-relevant fasteners; Mudguards/Wheel cover; Deflection device; Position of payload; Requirement for loading points/load securing; Ground clearance; Braking; Parking and stability; Tipping stability ; Steering functionality; Steering stability; Drawbar; Secondary safety device; Frame; Determination of and testing with test loads
