Comparison Qplay Nova+ Rubber vs Qplay Rito+ Eva

— From 1 to 3 years. The youngest age group. It covers only tricycles (see Type) and often includes additional safety features that allow parents to use the bike as a stroller. Such functions include, in particular, seat belts, bumper, visor(see “Equipment”) and parent handle (see below).

— From 2 to 4 years. This group may include all 3 types of bicycles (see “Type”). At the same time, three-wheeled models are usually less like strollers and are more designed for the child to move independently than in the previous group; for two-wheeled vehicles, the presence of side wheels is mandatory (see “Equipment”). And almost all balance bikes are designed for children 2-4 years old.

— From 3 to 6 years. For children of this age, a tricycle is already becoming uninteresting, and physical development makes it quite possible to learn to ride on two wheels. Accordingly, this category includes mainly two-wheeled models (see “Type”) with the mandatory presence of side wheels in the delivery set (see “Included parts”).

— From 5 to 8 years. Bicycles for children of primary school age are very similar to adult models: this includes only two-wheeled vehicles, and side wheels (see “Equipment”), although they can be found, are far f...rom necessary.

— From 6 to 10 years. Models in the older age category provide the opportunity to ride “like an adult.” This category includes bikes with wheels with a diameter of 20 ". Some models for this age already have a handbrake and some additional functions. However, such bicycles must be selected taking into account the child’s readiness for independent riding.

The limits of age groups are quite arbitrary, but it is not recommended to greatly violate age limits. In any case, it is necessary to take into account not only the ages indicated by the manufacturer, but also the general level of development of the child. Also note that children of a certain age may have different heights and builds; therefore, when choosing, you should pay attention not only to the age group, but also to the maximum load (see below)

The maximum rider weight that the bike can normally carry. This point is directly related to the age group (see above), however, bikes with the same age recommendations may differ in maximum load.

Of course, it is impossible to exceed the load specified by the manufacturer: even if an accident does not happen immediately, it can happen at any time. And ideally, you should choose a bike with a margin of weight — both in case of emergency situations, and taking into account the fact that the child will grow.

Bicycle wheel diameter is traditionally indicated in ". The overall height of the bike directly depends on this parameter, so each age category has its own wheel size - in accordance with the height of the young cyclist. However, cars of the same type and age group may differ in wheel diameter; this is especially pronounced among two-wheeled bicycles. In such cases, it is worth considering the following point: larger wheels behave better on rough roads and allow you to coast for a long time, but they are reluctant to accelerate and require more effort on the pedals; small wheels - on the contrary, they spin without much effort, but they hold speed worse and are more sensitive to pits and potholes.

Tricycles predominantly have a wheel diameter of 10 ", balance bikes - 12 ". In two-wheeled models, there are sizes in 14, 16, 18 and 20 ". Larger diameter wheels are no longer used in children's, but in teenage bicycles (they are listed in our catalog in the section with older bikes).

The design of the wheels mounted on the bike and the materials used for the tyre/rim.

— Inflatable rubber. Wheels with inflatable rubber tyres — the same as in full-size adult bicycles. Such wheels are quite demanding on maintenance: their condition must be monitored and, if necessary, pumped up. In addition, even a small puncture in a tyre makes it unusable and needs to be repaired. On the other hand, this is the most advanced type of wheel in terms of performance: they perform well even on rough roads, smooth out vibrations, provide good grip and are suitable for fast dynamic driving. And maintenance of inflatable tyres can be a good exercise for a young cyclist before switching to a teen bike. That is why two-wheeled models for older age groups are mainly equipped with inflatable tyres. However, this option can also be found in other varieties, including balance bikes and even tricycles (see "Type").

— Rubber. Wheels with a solid rubber tyre. Unlike the inflatable tyres described above, such tyres do not need to be inflated, and besides, they are not at all afraid of scratches and punctures. On the other hand, solid rubber wheels are less suitable for rough roads and high loads. Therefore, they are found mainly among bicycles for the smallest, and in the age category from 5 to 8 years, such wheels are not used at all.

— Polyurethane. By design, such wheels are similar to s...olid rubber wheels (see above), they differ only in the tyre material — this is polyurethane (an elastic synthetic material). Polyurethane is noticeably stiffer than rubber, so it is mainly used in tricycles that are not designed for fast driving and rough roads.

— Plastic. Wheels made entirely of plastic. The main advantage of this material is its low cost; in addition, it can be given almost any colour. On the other hand, plastic is hard and not very durable, it is not suitable for rough roads and high speeds. Therefore, these wheels are only used in tricycles and some balance bikes (see "Type").

— Plastic with rubber. A slightly improved version of the plastic wheels described above. Hard plastic in this case is complemented by a kind of analogue of a tyre — a narrow rubber strip around the circumference of the rim, where the wheel comes into contact with the ground when driving. This allows you to somewhat mitigate the vibrations that inevitably occur even when driving on smooth asphalt, but these differences between such wheels and purely plastic ones, in fact, are exhausted — plastic with rubber is also used only in tricycles, where the wheels are not designed for significant loads.

In the context of children's bicycles, alloy wheels refer to monolithic wheels made by injection molding. This is where they differ from traditional wheels, where the rim and hub are connected by spokes. Alloy wheels are typically stronger and more resistant to damage, and with fewer moving parts, they are easier to maintain.
