20" Kids Bike Guide

 

Kids Bike Guide

Learning to ride a bike has never been easier and there are a wide range of kids bikes to suit every child of every age. Choosing the right bike for your child can make all the difference to their cycling experience. In this guide we’ll look at all the features you need to consider when choosing the perfect kids’ bike.


Size and Weight

Is weight important?

Weight is probably even more important for a kid’s bike than an adult’s bike. This is because an adult’s bike can weight around 20% of their body weight while a kid’s bike can weigh up to 50% of their weight. A heavy bike is hard to ride while a lighter bike makes cycling easier and more enjoyable.

Some kids bike brands like Frog and Squish put a lot of focus on weight but the more you spend on a kid's bike, the lighter it will be.

Which size kids’ bike is best?

Kids bikes are sized by their wheel size. You will of course want the colour and style of your child’s new bike to be right, but the most important thing is to get one that’s the right size.

While it's tempting to buy a kid's bike that your child can grow into, so you can wait a little longer before buying the next size up, but a large, ill-fitting bike will be hard to ride, and can even put them off cycling.

Kids and junior bikes have wheels that are between 12” and 24” in diameter. Frame size is matched to wheel size and it’s this wheel size that gives the bike it’s overall size.

What to Look For in a 20" Wheel Kids Bike

Frame

Kids’ bike frames are usually made from steel or aluminium alloy. The best kids’ bikes have aluminium frames as these are lighter weight. The frame styles on these bikes start to follow the style of adult bikes. Most follow a mountain bike style that is versatile and easy to ride but comfortable hybrid style bikes and racy road bikes are also available.

Wheels

While all these bikes have 20” wheels the tyres will vary. MTB style bikes will have chunky tyres that work well on rough terrain. Road race style bikes will have narrower tyres that are fast rolling on smooth roads. Hybrid style bikes will have tyres that are somewhere in between the two.

It’s worth noting that BMX bikes also have 20” wheels but most of these are aimed at riders who are older than 10 years.

Brakes

Most 20” wheel bikes will have MTB style front and rear V-brakes. These offer powerful speed control and are easily adjustable. Higher end bikes may have kids’ specific disc brakes that offer next level speed control and are especially good in wet conditions

Whatever the style the brake levers should have a reach adjustment feature. This means that you can adjust the lever so that you child’s hand fits around it properly, and easily pull the brakes.

Gears

Most 20” wheel bikes have 6, 7 or 8 speed rear derailleur gears which enables your child to climb hills easier and expand their cycling horizons. Gear shifters will usually be the grip shift type although some road and MTB style bikes may have brake lever or thumb shifters.
