Safety Requirements for Bicycles for Young Children

GB 14746: Safety requirements for bicycles for young children

Scope of GB 14746 Standard

TheGB 14746 standard sets out all the safety requirements for children to use bicycles safely. This standard includes many factors, from the design of the bicycle to the materials used in its manufacture. In order not to put children's safety at risk, bicycles must be tested according to various criteria. Below are the key elements covered by this standard:

1. Bicycle Design and Construction

The design of children's bicycles should be done with the child's safety in mind. Elements such as the balance of the bicycle, handlebar height, saddle size, etc. should be designed so that the child can ride comfortably. In addition, sharp edges, hard surfaces and other potential hazards should be eliminated.

Balance: The bicycle should be stable and the child should be able to balance easily. This minimizes the risk of the child falling.
Control: The bicycle should be easy to control, and the handlebars and brake systems should be designed so that children can reach them easily.

2. Material Selection

GB 14746 requires that materials used in the manufacture of children's bicycles must be safe and durable. No part of the bicycle should be designed or manufactured in such a way as to cause harm to children's bodies. In addition, the materials used must not contain toxic chemicals.

Durable Materials: The frame, brakes, wheels and other parts of the bicycle must have high durability.
Non-toxic Paints: Paints and coatings on the bicycle must not contain substances harmful to children's health.

3. Safety Equipment

TheGB 14746 standard requires safety precautions to be taken on children's bicycles. This relates in particular to the moving parts of the bicycle. The design of the elements that make the bicycle work, such as pedals, chains, brakes, etc., must be such that they prevent injury to children.

Brake System: The braking system on the bicycle should enable the child to stop comfortably and quickly.
Pedals and Chain Guards: Chains, pedals and sprockets must be protected so that children cannot pinch their fingers.

4. Wheel Safety

The wheels of children's bicycles must be the right size and properly positioned to ensure safety. In addition, sufficient resistance must be provided so that the wheels are not at risk of excessive rolling.

Characteristics of the Tires: The tires should allow the child to move freely when using the bicycle and minimize the risk of slipping.

5. Other Safety Features

Recycling Labels: The bicycle should be labeled for recycling at the end of its useful life.
Reflective Materials: Reflective materials can be used to increase the visibility of the children's bicycle. This helps prevent accidents, especially when cycling at night.

The GB 14746 standard includes terms and definitions of bicycles for young children aged approximately four to eight years with a maximum seat height of more than 435 mm and less than 635 mm, as well as safety and performance requirements for these bicycles and test methods for design, assembly and testing.

The tests performed within the scope of the standard are as follows:

Brake block test
Brake system load test
Manually operated brake performance test
Rear pedal brake performance test
Steering assembly test
Impact tests on frame/fork assembly
Falling mass test
Drop frame/fork assembly test
Wheel static load test
Pedal/crank group kinetic test
Static load test - Saddle and column
Drive system static load test
Stabilizers - Vertical load test
Stabilizers - Longitudinal load test
Saddle strength test
