How to measure bike size
To find the best size of bike for your child, you need to consider their height and the length of their inside leg. Watch the videos below to see step-by-step guidance on how to get the measurements you need.
How to tell if a bike is the wrong size
- Their feet don't touch the ground when the bike is upright.
- Their legs are significantly and uncomfortably bent when using the pedals.
- They have to stretch to reach the ground or handlebars.
Types of bikes - toddlers
Children can learn to ride a bike from as young as 2 years old. You have two choices when it comes to beginner bikes; balance bikes, which don't have pedals or a brake and beginner bikes, which have brakes, pedals and use stabilisers to keep them steady.
Types of bikes - big kids
When your child has mastered the art of cycling, they may be ready for a big kid bike. Here are some of the options to choose from.
Kids bike safety
It's essential for kids to stay safe when they cycle and take measures to prevent injury.
The highway code recommends that all cyclists wear a helmet and a bike must have lights, especially if you plan to ride when it's dark.
Knee and elbow pads provide added protection against falls, while you should also regularly check your tyres to ensure they are properly inflated.
