Assure the rim to well anti-heated for long time riding, to increase braking performance and durability, and greatly improve the braking performance of the wheelset in rainy days or wet conditions.

Learn more about 20 inch wheel kids' bikes

 

20 inch wheel kids' bikes signify a coming of age for that children who are now taking their first tentative steps into the world of serious bikes.

 

These bikes feature geared drivetrains, stronger frames and stiffer wheels, often fitted with knobby tyres. It's time to explore.

 

In effect, most of the 20 inch wheels bikes are 'junior mountain bikes' - 20 inch wheel mountain bikes are ideal for all terrain adventures; they are robust, lightweight, and have a wide range of gears, to ensure your child is riding comfortably and safely at all times.

 

Braking on these bikes comes from V-brakes or disc brakes; with the latter providing more stopping power, but being more costly. Flat pedals are fitted to all these kids' bikes, and the ones on 20 inch child bikes have a larger profile, to accommodate larger feet.


 

 

Guide to Kid Bike Sizes

 

The first step in picking a bike is getting the right size. Where adult bikes are sized by the frame (measured from the center of the bottom bracket to the top of the seat tube), bikes for children are sized by their wheels: 12”, 16”, 20” and 24”. The bike should fit the child. The rider should be able to dismount and comfortably straddle the bike flat footedly. And then with a slight lean of the bike, get their bottom back onto the seat, put their foot on the pedal and, when the skill is there, ride away. They shouldn’t be riding scrunched up with their knees hitting the handlebars and they shouldn’t be stretched out and unable to turn the handlebars easily. At the slow speeds that kids start out riding at, steering by turning the handlebars is much more of an element of riding than at faster speeds where steering is done largely by leaning. If there are training wheels on the bike, all of the steering is done with the handlebars.

The size doesn't have any relationship to a real measure: It is certainly not the diameter of the rim. Generally the given size is closer to the tire/tyre diameter from tread-to-tread, but it is usually greater that this distance as well.
