Comparison Razor Beast V3 vs Razor Grom

The minimum age at which a child can be entrusted with a scooter. These recommendations are quite approximate, but it is highly not recommended to deviate from them. In the case of electric scooters (see "Type"), it is worth considering that in some countries, to control such devices, you need rights obtained from a certain age; so when buying a similar model, it's ok to clarify the requirements of traffic rules.

The allowable load directly depends on the age group; according to this criterion, modern scooters can be divided into children's(permissible load up to 50 kg), teenage(from 50 to 80 kg), and adults(80 kg or more).

— T-bar. A traditional scooter handlebar in the form of a horizontal crossbar on a vertical bar. It is found in almost all types of scooters. Note that in kickboards such a steering wheel usually needs to be tilted rather than turned.

— Bike handlebar. The handlebar has a characteristic curved shape, in which the handles are bent back or moved upward relative to the middle. It is considered more convenient than the classic one, but it is more complex in design and costs more, and the difference in convenience is not so often noticeable. Therefore, this option is found much less frequently, mainly in fairly advanced models — in particular, most bicycle scooters are equipped with just such handlebars.

— Round handle. The handlebar is in the form of a ring or a pair of rings (a kind of “ears”) mounted on a vertical rod; There are also options without a top ring at all, in which the rod ends with a round knob. In any case, this design is used in models where the handlebar does not turn, but tilts from side to side — these can be either kickboards or some specific trikes (see “Type”).

— Y-bar. A handlebar with a bend in the top tube in the shape of the letter Y. Often in such handlebars, side supports are used to strengthen the structure, due to which Y-shaped handlebars are considered more durable in comparison with classic T-bars.

...— Bat-Wing. The shape of the Bat-Wing resembles Y-shaped rudders, but in the upper segment of this version, there is a special horizontal crossbar to strengthen the structure. Bat-Wing handlebars can withstand heavy loads and are installed primarily on stunt scooters.

The weight of the scooter, its strength and resistance to stress depend on the material of the deck. In modern models, the following options can be used:

— Plastic. In scooters, this material belongs to the entry-level. The strength of plastic is low, it is not designed for heavy weight and serious loads — and, therefore, it is found mainly in models of the younger age group and the classic type (see above). On the other hand, in this category, plastic shows itself at its best: it can have almost any colour and pattern, it weighs a little, and it is inexpensive.

— Aluminium. Aluminium-based alloys combine strength, resistance to stress and low weight, due to which they are quite popular as a material among all types of scooters (see above).

— Steel. The main advantage of steel is its high strength, exceeding even aluminium, not to mention plastic. On the other hand, this material has a large weight and therefore is used less often than others, mainly in bicycle scooters (see "Type") of the older age group.

— Magnesium alloy. A fairly advanced material that combines very low weight with high strength and elasticity. At the same time, its cost is also quite high. Therefore, magnesium frames can be found mainly in expensive premium models.

— Carbon. Thi...s term usually refers to carbon fibre — carbon fibre in combination with a polymer filler. Carbon is considered a premium material: its strength is comparable to steel, and its weight is much less. However, such material is sensitive to point impacts — cracks may appear from them. However, in general, such a “trouble” requires a rather unfortunate set of circumstances. But one of the unequivocal disadvantages of carbon can be called a high cost. In addition, we note that this material is used mainly in electric scooters (see "Type") — for other varieties, for several reasons, it is easier to use more affordable materials, even if we are talking about an expensive and high-quality model.

 

Bearings that the scooter is equipped with. This paragraph usually indicates not the model/brand, but the class of bearings according to the ABEC standard. Standard options for modern scooters are ABEC 5, ABEC 7, and ABEC 9 ; the higher the number, the higher the quality and accuracy of the part.

There is an opinion that better bearings allow you to accelerate better and go faster. This is partly true, but acceleration and speed are highly dependent on a number of other points — the size and material of the wheels, the weight of the scooter, etc. So models with bearings of the same class can differ markedly in speed characteristics. But what this indicator unambiguously affects is durability and price: high accuracy affects the cost, but such bearings last longer and carry loads better.

Also note that for relatively simple use, ABEC 5 class bearings are quite enough. It makes sense to specifically look for a model with ABEC 7 or ABEC 9 only if you need a scooter for advanced stunts or professional high-speed riding. However, if the selected model has high-quality bearings, it will not be worse from them anyway.

The maximum height to which the height-adjustable handlebar can be set (or just the height of the handlebar in the working position, if height adjustment is not provided).

The height of the handlebars should be such that the rider can stand on the deck straight, without bending his back, and hold on to the handles with slightly bent arms. At the same time, there is no unambiguous relationship between this parameter and the height of the rider. So the perfect option to determine the optimal height is to try it yourself, and then choose a scooter based on the result.

Scooter deck size. This item can indicate both the length and width or only one size — most often this is the length.

In general, this parameter is secondary: manufacturers choose the size of the deck depending on the type, age category, general specialization and other features of the scooter. Legroom, usually, is guaranteed to be enough on the deck. We only note that shorter decks are more agile, and longer ones are stable on the course.

This term refers to the useful area of the deck on which you can put your foot. It is size without taking into account the folding mechanism, wheel fastening and other elements that are not intended for the leg.

The total weight of the scooter; for electric models it is the total operating weight is indicated, with batteries installed.

This option has two meanings. Thus, lighter scooters accelerate and manoeuvre better and require less effort from the user. In turn, more massive models maintain speed longer and are more stable on the course. In addition, note that less weight, other things being equal, means either less strength or more cost.

The lightest modern scooters weigh less than 2 kg — these are mostly relatively inexpensive classic models and kickboards (see "Type"). Sports models already have a weight of 2.5 kg, and often more. The most massive among non-self-propelled models are scooters — from 5 kg. And electric scooters inevitably turn out to be heavy due to motors and batteries, their mass can reach 10 kg or even more.
