Buying Guide

Thinking of buying a bike for your kid? That can be a bit difficult since the matter involves your kid, and anything like that has to be difficult, right. Buying a bike for your kid can be complicated because he/she might still be learning and not so skilled, of course, so it gets unclear as to what to look for in a bike for your kid.

To buy a bike for your kid, you need to consider certain criteria, which are provided below. You can rely on the buying guide provided below, and after going through these considerations, you will find the decision-making facilitated and much easier.

Bike Size

standard bike size

Since your kid is not yet a highly skilled rider neither too grown-up, he/she needs to get acquainted with and used to a bike; normally, the right size for a kid is around 20 inches. Although, you should consider your kid’s height before deciding the right height of the bike for him/her.

The size of the bike should be neither too small nor too large for your kid since, in both cases, it can be dangerous. For the bike to be controllable, it needs to be the right size. If buying online, there are many brands that provide a sizing chart to choose the perfect size for your kid; go through that properly and carefully and decide accordingly.

The weight of the bike is also important for the bike to be easily controllable by your kid. A bike too heavy cant be handled by your kid, and you definitely wouldn’t want that. Other than that, adjustable seat height and tire width are also crucial for the comfort and balance of your kid’s ride.

Brake Type

The most undeniable necessity in your kid’s bike has to be a nice and effective braking system. There are multiple types of brakes; to pick the right brake type, consider your child’s ability, practice, and age. For instance, the coaster brakes require reverse pedaling for the stoping, which can be frustrating for kids with no practice since reverse pedaling is normally used to go backward.

The handbrakes are the brake levers on both the handlebars; the problem with handbrakes is that they can be too large hence a bit difficult for the little hands of your kid to control. If you opt for handbrakes, make sure that they are child-specific, easy to access, and easy to control for your kid. If the bike has only handbrakes, then make sure that they are high-quality with lasting and effective functioning.

There is also an intermediary option, that is a choosing a bike with both handbrakes and coaster brakes. The advantage of such a bike is that your kid can choose what he/she is most comfortable with and develop that skill. Plus, there’s also an enhanced safety quota; with two types of brakes, there are rarely any chances of their failure.

Tires

Some key considerations about the tires of your kid’s bike are essential to be made. Wider tires, like those of a mountain bike, are particularly good for children. Firstly because they offer a nice balance and stability, secondly, because they can run on low pressure hence can cushion the ride. They also provide better traction on various surfaces. You can choose the thin wheels later when your kid is all prepared and equipped with the skill to ride on those.

FAQs

Does Mongoose still make good bikes?

What age is a 20-inch BMX bike for?

20-inch wheel BMX bikes are normally ridden by all, including children and adults. The minimum age, however, would be between 7 to 8 years.

Is a 20 bike too big for a 6-year-old?

If your 6-year-old has a longer inseam, between 18 to 22 inches, he/she needs a 16-inch bicycle. For a larger 6-year-old measuring 42 to 28 inches in height with an inseam of 20 to 24 inches, choose an 18-inch wheel.
