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).
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.
Deck size
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.
Weight
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.
