24 Inch Bicycle – To What Size Kids?

Navigating through the world of kids’ bikes is both a joy and a challenge for most parents.

Children grow quickly, their riding abilities expand, and the need for a larger and more versatile bike emerges as a consequence.

Therefore, it’s important to know when your child is ready for a 24-inch bicycle, which is the logical size to transition to from smaller-sized bikes.

Below, we’ll explain how kids’ bikes are measured and our handy interactive calculator will tell you which age and size kids are best suited for a 24-inch bicycle.

How to Measure a 24″ Kids’ Bicycle?

Understanding how children’s bicycles are sized is the first and crucial step to finding the right fit.

Unlike bikes made for adults (primarily measured by their frame size and seat tube length) bicycles for kids are measured based on their wheel diameter.

That means that a 24-inch kids’ bicycle is a bike with a 24″ wheel diameter, not a 24″ frame size. By using this sizing method, you can quickly narrow down your search for the perfect bike size for your child.

Measuring Instructions

Measure the diameter of the existing tire, as illustrated above (D), or look on the tire for the size (it looks like this: nn" x n.n").
If you find the tire size, the first dimension is the tire diameter, the second dimension is the tire thickness.
Record the tire diameter, as this also represents the bike frame size.

Frequently Asked Questions

1. What age is a 24-inch bike for?

A 24-inch bike typically caters to kids 8 to 13 years old. Generally speaking, most older school kids and younger teenagers should be able to comfortably ride a 24-inch bike. But children at this age differ significantly in height and leg length, so it's best to consult the manufacturer's sizing chart before buying.

2. How tall should I be for a 24-inch bike?

In order to ride most 24-inch bikes, you should be around 3' 10½" to 5' 6½" tall (119 - 169 cm). However, keep in mind that manufacturers have different size recommendations for their models, so it's best to take this information as a starting point and check the manufacturer's sizing chart before making the final decision.

3. Is a size 24 bike for adults?

A 24" bike is intended for kids and younger teenagers, but some short adults can ride it as well. If you are around 5'0" tall or less, you should be able to ride a bike with 24" wheels. But it's best to test-ride the bike before purchasing to make sure the fit is right.

4. Can a 14-year-old ride a 24-inch bike?

Yes, most 14-year-olds should be able to comfortably ride a 24-inch bike. These bikes are intended for teenagers and older school kids, but the actual size and fit depend on the rider's height and leg length. Some taller 14-year-olds may be better with an adult bike, whereas shorter riders would be better off with a 20" bike.
