A 24 inch bike is usually found on the kids bike market, but some brands also have this type of bikes for adults, for example, the 24 inch folding bicycles. Thus, the theory that I have told you above, may not work in some situations.

Now you may think that answering the question of a 24 inch bike for what size person is not quite easy.

But no worries. In the following words, we will work together to figure it out and make it clear for everyone. Keep reading.

What is a 24 Inch Bike

Owing to bicycle brands having many ways to tag their products in size, many buyers may not make it clear what a 24 inch bike means. A 24 inch bike refers to a bicycle that has wheels with a diameter of 24 inches.

Like we have mentioned, most 24 inch bikes are designed for kids. But you can still find this type of bicycles specifically designed for adults, such as folding bicycles and city bikes.

Who Size and Age Person Can Ride a 24 Inch Bike

While height is a crucial factor in bike sizing, it’s important to note that individual proportions and preferences can also play a role. As a general guideline, a 24 inch bike is ideal for riders who are 8- 12 years old, usually in their preteen years, and between 4’6″ and 5’5″ tall, minimum 4’2’’, depending on the frame size and type of bike.

Some adults must wonder “can adults, especially women, ride these bikes?”

Of course, as long as these bicycles can perfectly fit you, you can definitely ride them. However, since they are kids bikes, they must have very crucial weight limits. And considering adults are normally much heavier than the children, so before you sit on it, please make sure that your weight is under its range.

Besides, if you really want to try a 24 inch bike, you can also find one that is specially designed for adults, like an adult 24 inch folding bicycle or an adult 24 inch city bike.

But please note that these bicycles can have many size options and cover all riders with different heights. When you choose such a 24 inch bike, the height recommendation above is not enough and 100% correct. We need to take some other methods to help you choose the right frame size for a 24 inch bike.

Types of 24 Inch Bikes

Kids Bike

Kids bikes are bicycles that are designed for children of different ages and sizes. Since they are for children, they usually have smaller frames, wheels, and components than adult bikes, and some of them also have training wheels, balance bikes, or other features to help kids learn how to ride.

For the kids bike wheel size, there are several options: 12 inches, 14 inches, 16 inches, 18 inches, 20 inches, 24 inches, 26 inches, and each of them correspond to kids height and age.

Wheel SizeAgeMinimum Height
12 inches2+2 feet 8 inches (or 88cm)
14 inches3+3 feet 3 inches (or 98cm)
16 inches4+3 feet 5 inches (or 104cm)
18 inches5+3 feet 8 inches (or 112cm)
20 inches6+3 feet 11 inches (or 120cm)
24 inches8+4 feet 2 inches (or 127cm)
26 inches10+4 feet 7 inches (or 140cm)

Folding Bicycle

Folding bikes are bicycles that can be folded into a smaller size, making them easier to transport and store. They are ideal for people who live in small spaces, commute by public transit, or travel frequently. Folding bikes come in different styles, sizes, and prices, depending on your needs and preferences.

Obviously the biggest feature of this type of bicycle is that they can occupy much smaller space. So the 24 inch wheels can achieve this goal, even though they are not as good as the 16, 18, and 20 inch wheels.

City Bike

City bikes are bicycles that are designed for riding in urban environments. They are usually lightweight, simple, and comfortable, and often have features that make them more convenient and practical for commuting, shopping, or leisure. And many riders do not have the pursuit of speed and performance. Thus a pair of 24 inch wheels can help a lot.

How to Choose the Right Frame Size for a 24 Inch Bike

Here what you will learn to help choose the right bicycle frame size is by your inseam length. Compared to other methods, it is much easier to operate. You can do it at your home.

For your reference, your inseam length is the distance from the ground to your crotch, and it plays a significant role in determining the correct frame size for your bike. And before we dive into finding the ideal frame size by the inseam length, obviously, we need to measure the inseam length, if you don’t have your own.

Measuring Your Inseam Length

To measure your inseam length, follow these simple steps:

1. Stand barefoot against a wall with your feet shoulder-width apart.

2. Place a book or a flat object between your legs, right up against your crotch.

3. Make sure the book is parallel to the floor, and mark the spot where the top of the book touches the wall.

4. Measure the distance from the floor to the mark using a tape measure or a ruler.

Now that you have your inseam length, let’s move on to finding the right frame size for your 24 inch bike.

Finding the Ideal Frame Size

To determine the ideal frame size for your inseam length and the type of bike you want, you can use formulas that take into account your measurements and the specific bike type. Here are a few formulas you can use:

1. City & Folding Bike: Frame Size (cm) = Inseam Length (cm) x 0.65

2. Mountain Bike: Frame Size (inches) = (Inseam Length (inches) x 0.66) – 15

3. Road Bike: Frame Size (cm) = Inseam Length (cm) x 0.70

Since mountain bikes and road bikes have few options for the 24 inch bikes, you can just ignore their formulas.

Besides, out there on the bike market, many city and folding bicycle brands may not use the centimeter to describe the size of their bikes, but are more likely to use the T-shirt size way. And if you are in such a situation, here is a size chart with both height and inseam length numbers, which can help you.
