Bicycles 20 inches: features, types and choices

Children's bicycles today are represented by a large variety of models and sizes. Among the offered assortment, vehicles with 20-inch wheels stand out, which have their own characteristics.

Today, manufacturers of children's mobility aids classify their products based on the size of bicycles, wheels and other important parameters. Models with 20-inch wheels are recommended for older children due to their size.

Due to the fact that such devices are singled out in a separate category of children's bikes, they have individual characteristics.

• As a rule, most of the products sold initially do not have side safety wheels as standard. This device is due to the fact that by the age recommended for riding a bicycle with 20-inch wheels, the child will already be able to independently maintain balance and control the riding device.
• However, the range of such products still contains some exceptions regarding the presence of safety wheels on the rear wheel. This applies to single speed bicycles. In other cases, there are speed switches on the back of the structure, which will not allow you to attach additional components to the wheel.
• Among the features of such varieties, it is worth noting the presence of a manual-type brake system. It will be presented in two forms: front and rear brakes, which will allow you to pedal backward.
• It is worth noting the similarity of such models with adult bicycles, not only due to the high-speed transmission and braking system, but also due to the presence of a shock-absorbing fork in the design, which is usually absent on the previous models.
• The manufacturer equips its products with a similar wheel diameter with a protective system for the limbs, which prevents the child's feet or clothes from getting into the spokes of the wheels. In addition, the bikes will have a secure chain sleeve.

As for the main components of the design, they have their own specific characteristics.

Unlike lightweight children's versions on three wheels or models with smaller wheel diameters, the frame for bicycles in this category is made from durable raw materials. As a rule, steel or aluminum is used in the factory.

The aluminum frame will have less weight, which is an important characteristic for a child's vehicle.

However, both materials stand out resistance to rust formation, retain their shape in case of mechanical damage, in addition, aluminum and steel frames are characterized by excellent maintainability.

For such products, durable rubber tubes are used, due to the size, a child who confidently operates such a bicycle is able to reach speeds of 15–20 km / h, as a result of which bikes with 20-inch wheels can be compared with adult pleasure bicycles in the manner of movement.

In addition to the above attachments, which also largely determine the weight of the bike structure, children's products include tires and rims, speed switches, and a fork.

In the product overview of modern manufacturers, you can find models which in appearance can be divided into two groups:

• accessories for boys;
• designs for girls.

In general, the presented species from the two categories differ little from each other. The difference only concerns the colors used for the design of the structure, as well as other accessories in the design of the bike.

It will also be possible to divide 20-inch bicycles into types, taking into account the peculiarities of their design. Now for a child, you can buy a choice of a monolithic or a folding bike. The last option is distinguished by the advantage regarding the convenience of transportation in personal or public transport. Unlike standard models, the folding versions do not need to unscrew the wheel first - for storage or transportation, the models are equipped with a special mechanism on the frame, which allows it to be folded.

In terms of running parameters, this group of bicycles may be slightly inferior to monolithic structures. That's why models with this configuration are recommended as walking options. Varieties can be produced with or without shock absorbers. Also on sale you can find products with a different number of speeds. There is no need to use additional tools to disassemble or assemble the bike frame. It is also worth noting availability of models with the ability to remove the pedals and steering wheel.

Manufacturers of children's bikes, dividing their products into age groups, adhere to a certain table of correspondence between the height and weight of the child and the dimensions of the manufactured structures.

It is believed that a child whose height has already reached 126 centimeters should purchase a model with a large wheel diameter. According to the average values, the optimal age for a cyclist capable of driving such a model would be 6 years. Wherein the baby's weight must be at least 20 kilograms.

• It is important, regardless of the parameters recommended by the manufacturers of children's bicycles, to take into account the individual characteristics of the child when buying a riding device. It is best to choose a model together.To determine the conformity of the design to the child's height, it will be enough to sit him on the saddle. If the design is in size, then the child's feet can freely reach the pedals, hands - to the steering wheel. In addition, while pedaling, the rider's knees should not touch the handlebars.

• An important factor that will indicate the correct size will be the flat back of the cyclist, who comfortably fits into the seat and grabs the handlebars.

• Considering a model with a lowered frame, it is worth remembering that the design will be suitable only if the child standing on the floor with a frame between the legs, the removal of the component from the crotch will be at least 7 centimeters. A smaller step can make it harder to jump off the bike in the event of an injury hazard.
