20-inch bikes are typically appropriate for children aged 6–10 years. The usual size for a BMX wheel is 20 inches, and because they both have no gears, the 20 inch kid's bike and BMX have many similarities. Kids' bikes generally weigh less than adult bicycles, and have smaller wheels and tires for street riding rather than off-road use.
The typical BMX bike has three parts: footboard, base, and handlebars. The footboard is a platform that connects to the bottom of the frame below the seat tube. It provides a flat surface on which to mount the feet when jumping or performing other tricks. The base is where the drivetrain (chainring/cogset) is attached. This is usually done using a bolt that goes through the center of both components. The handlebars are the two pieces that hold the bicycle's front wheel. They can be flat or curved, but usually have flat ends for better control.
Kids' bikes usually don't have any gear ratios except for the largest size available, which is 1 for 10 or 1:10. This means that if you put one more sprocket on the hub in order to go faster, you have to change wheels. On a standard bike with multiple sizes available, this would not be an issue because you could just get another size pedal and rack.
Finally, the 20-inch BMX bikes are suitable for children aged 13 to 14. BMX Sizing Chart by Age and Bike Size

There is nothing quite like a 20-inch bike in the world of cycling. Smaller bikes are classified as children's bikes, whilst larger two-wheelers are intended for older children, teens, and adults. That is not the case with the 20-inchers. These bikes are perfect for people who are 5'4" or taller! They provide better posture and lower centers of gravity than larger bikes, which is important if you plan to ride far or up hills.
These days, you can find 20-inch bikes available in a variety of styles. There are full suspension models for riding down hills and cross-country travel, there are frames designed for easy maintenance and low cost of ownership, and then there are ones that look cool too! If you're looking for a new bike, consider one of these smaller options. You'll be able to go farther and faster while keeping your body in good shape.
Of course, not all 20-inch bikes are created equal. Some will be better suited for certain types of riding than others. For example, if you plan to ride rough roads or carry large loads, you should get a model with stronger wheels and tires. Otherwise, you might want to look at bikes with lighter components for easier handling and less fatigue on long rides.
The best part is that you don't have to spend a fortune to get into a quality 20-inch bike.
8-11 year olds or 120-148cm-24" kids bikes Youngsters's 24 inch geared bikes are appropriate for children aged 8–13. These 24 inch motorcycles are constructed in the form of a mountain bike, with equipment such as gears and suspension forks. A kid's bike will usually have smaller wheels than adult bikes (typically 22 to 28 inches), thinner tires (usually 700c instead of 26"), and less suspension travel (usually about 150mm instead of 200 or more). Some manufacturers make kids' bikes without rear brakes because children can be expected to learn how to ride with only a front brake.
13-16 year olds or 148-175cm-56" kids bikes Older teenagers and adults may choose to purchase larger sized bikes that are better suited to their age and riding experience. These bikes typically have larger wheels (29" or more), thicker tires (700c or more), more suspension travel (250mm or more), and more expensive options like disc brakes and full fenders.
The best kids' bikes for your child will depend on their age, riding experience, and transportation needs. There are two types of kids' bikes: geared and non-geared. Gearing refers to the use of gear ratios to increase or decrease the speed of the pedal rotation. This allows young riders to go slower on long stretches of road and faster up hills.
Unlike adult sizing, which is determined by the bike frame, the proportions of children's bikes are determined by the wheels. With one-size balance bikes for children, bike wheels start tiny. Similarly, the appropriate bike size for a 5-year-old falls within the same range. A 20-inch wheel bike will suit most 8 and 9-year-olds. For those who are taller or heavier, a 21-inch or even a 22-inch wheel bike may be needed.
There are two types of balancing bikes: ones with two wheels of equal size (called "bi" models) and ones with two wheels of different sizes (called "di" models). On di balancing bikes, the larger wheel is usually mounted on the front. This makes it easier to push off the ground when riding in a circle, which is required to learn how to balance properly.
The best age to start learning how to balance a bicycle is when you're young. By practicing every day, your body will become more familiar with the movements necessary to ride a bike. And you'll get used to the feel of the pedals under your feet.
Once you know how to balance a bicycle, it's important to practice safe cycling skills. It's best to learn this from an experienced person first, so that you don't hurt yourself while being careful not to hit any pedestrians or other cyclists.
The 20-inch frame accommodates older, taller youngsters than the 16-inch frame. In addition to the coaster brake, these bikes may incorporate hand brakes to enable the youngster learn to use their hands to slow or stop. They are more difficult to ride due to their larger size and heavier weight.
The larger frame is also more stable, which helps to minimize the risk of injury when riding over rough surfaces. The bigger wheelbase provides better traction in snow and mud, while the increased tire width offers greater coverage when spraying water for cooling during hot summer days out on the trail.
These bikes are best for young riders who have not fully developed their bodies or mastered their skills yet. They are often built with lighter-weight materials used by adult cyclists who are just getting started outdoors.
Bikes in this category are usually sold as pairs. One bike will be given to an underage rider for his or her own use while the other keeps up with the family trade shop. These bikes are commonly found in black or white with red accents. They typically come with simple flat tires that are easy to repair or replace.
You can find adult bicycles built for much longer distances. These usually have thicker frames, wider wheels, and stronger brakes.
