A child's bicycle

Your child’s safety is at stake … so it pays to inspect a bike closely before buying. (This will be easier to do if the bike’s pre-assembled or if there’s a display model).

Here’s what to look for – and where to go:

  • Specialist stores: Try a bike shop first. Going to a specialist store means it’s more likely your child can try a bike for size and you can make sure it’s suitable. Most bike shops allow test rides. Assembly may also be part of the deal. 
  • Construction: Bikes should have consistent welds on the frame joints. Avoid a bike with patchy or missing welding. Shake it a little to see whether anything rattles or is loose. Make sure there are no sharp objects sticking out – these could harm your child.
  • Wheels: Try placing the bike upside down and spinning both wheels. Make sure that they don’t wobble, and that nothing is rubbing against them.
  • Brakes: Look for back-pedal brakes – these allow the child to stop the bike by simply reversing their pedalling. Handlebar-operated wheel-rim brakes are common on adult bikes, but smaller children may not have the strength to pull them hard enough. Note the size of the brake pads (smaller ones will wear out sooner).
  • Value: Don’t be swayed by prices or brands. As our testing shows, a low price tag doesn’t mean a poor-quality product.
  • Size: A bike’s the right size when your child can sit on the saddle while resting the balls of both feet on the ground. They also should be able to reach the handlebars with a slight bend in their arms. A seat and a handlebar stem with plenty of adjustment will mean your child can still fit on the bike as they get bigger.
  • Pedals: Watch out for “basic” pedals. They’re often smaller and don’t have as much grip on them (you want your child to have as good a grip as possible).

Size and age

Not sure what size bike to buy? Here’s how wheel sizes correspond with a child’s age:

  • 12" / 30cm: 2-5 years
  • 16" / 40cm: 4-8 years
  • 20" / 50cm: 7-11 years

Note: This is an approximate guide only. Children of the same age can vary considerably in height, so it's best to try bikes for size if you can.
