Max. load
The maximum weight of the rider that the design of the scooter can withstand without breakdowns and accidents. This point is partly determined by the age group, and mainly by the materials used in the frame (both points below). Note that manufacturers can indicate the maximum load for perfect conditions — when the scooter rides on a perfectly flat surface or even stands still. Therefore, it is worth choosing a model for this parameter with a certain margin; this is especially important for varieties designed for increased loads, in particular scooters and stunt models (see "product type"). Even more so, you should not exceed the weight indicated in the characteristics — even if the scooter does not break down immediately, this can happen at any time after, which is fraught with accidents and injuries.
Age, from
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).
Handlebar type
—
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.Handlebar material
The material of the handlebar carries almost the main information about the strength of the scooter since the rider leans on it while riding. Accordingly, this structural element in most cases is made of metal, namely:
—
Aluminium. The key advantage of aluminium is its light weight. Handlebars made of aluminium are much lighter than their steel counterparts. A scooter with an aluminium handlebar can be a good choice for stunt riding. But to make an aluminium handlebar strong enough manufacturers have to increase the size and wall thickness. As a rule, aluminium handlebars have a non-standard increased tube size of 34.9 mm. Additionally, aluminium handlebars are more expensive than steel counterparts.
—
Steel. The main advantage of steel is increased strength — such a handlebar can easily withstand high mechanical loads. But among the shortcomings can be noted high weight. Steel wheels have a high mass, which somewhat limits their scope, especially in terms of stunt driving.
Deck material
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.Clamp
—
2 bolts. 2-bolt clamp — such clamps are typical for entry-class scooters. A 2-bolt clamp usually connects steering elements in city scooters. M8 threaded fasteners are most often used as bolts. The 2-bolt connection is ill-suited to resist loose fasteners.
—
3 bolts. Clamp for 3 bolts — this clamp allows you to more or less securely fix the steering elements. Scooters with a 3-bolt clamp are usually considered stunt scooters but belong to the entry-level class. The 3-bolt fastening allows the clamp to prevent loosening in the connection.
—
4 bolts. 4 bolt clamp — this category of clamps is typical for good stunt scooters. Such a connection allows you to securely fix the steering elements. The presence of 4 fixation points allows the connection to resist loosening well, and the bolts in such clamps are slightly subject to self-loosening.
—
5 bolts. The 5-bolt clamp is a quality clamping solution found on advanced stunt scooters. The presence of 5 fixation points allows you to securely fix the steering wheel in the desired position. The 5-bolt clamp will not allow play to appear in the connection. Such clamps can maintain the degree of tightening of fasteners even under high-vibration loads.
Front wheel size
The diameter of the front wheel(s) of the scooter.
This parameter is selected by the manufacturer depending on the type, age category and general purpose of the scooter. If we compare similar models with different wheel diameters, then it is worth considering that the larger the wheels, the better they work on the bumps in the road, and the higher the cross-country ability. And small wheels, in turn, are great for smooth asphalt and dynamic driving, they easily accelerate and allow you to make sharp turns.
Rear wheel(s) size
The diameter of the rear wheel(s) of the scooter. See "Front wheel diameter" for details on the value of this parameter.
Max. height
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.
