It’s usually best here to choose the smaller size. Why is that? Well, a larger bike will typically be harder for a child to steer, stop and start, especially where they might need to stand on their tiptoes to reach the floor. This larger bike might feel more intimidating and less comfortable, especially for less confident riders. As the feelings of control, security and confidence are key to an enjoyable cycling experience for kids, it’s clear to see why a smaller bike is likely to offer a better experience here if you’re unsure between sizes.The exception to this guidance would be that if the child is really on the cusp of the larger size, it might be a better idea because they’ll be able to enjoy riding it for much longer, as well as have a more efficient pedal stroke on the larger bike.

Interestingly, it’s not only your child’s measurements that can dictate which size will be best for them. Their skill level also has a bearing on what size and weight of bike will be best.A less confident or less skilled child might really benefit from a slightly smaller, more lightweight bicycle. This is because they tend to be easier for the child to handle and manoeuvre, as well as to get onto and dismount.Having said this, the most key part will still be getting the basic fit right, again for your child’s physical size, rather than age.
