Kids' bikes are typically sized by the size of the wheels. The smallest pedal bicycles usually begin with only 12-inch tires, while larger bikes go up all the way to 24-inch tires. Some even make smaller kids bikes when your kiddo isn't ready for a full grown bike. Still, no matter the size, all kids bike sizes should have pedals that are made for children of that age.

The size of your kid's bike depends on your child's height and weight. You want to be sure that the seat and handlebars can handle your kids' weight before you buy them. Some bikes are made bigger so that they can accommodate growing riders. Before you decide on a bike, take these factors into consideration.

One of the best qualities of kids bikes is that most have training wheels and front brake discs. If your kids will be using their bikes for lots of riding in wet weather, front disc brakes are recommended. The front brake calipers and pads provide better stopping power than rear disc brakes. If your kids aren't going very fast, then a training set up with lower front shocks and suspension will provide good handling. However, if your child is going fast, consider getting a bike with high performance suspension and a higher shock absorber.

When it comes to kids bike safety, parents often get stuck on which size is right for their child. There are actually several factors that determine which size bike is best for your child. They include your child's body size and head size, the type of terrain they bike on (whether it's a dirt road sidewalk, or mountain) and their age. All kids bike sizes are not created equal, so make sure you get the correct size for your child.
