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
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.
Bearing
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.
Footspace
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.
Clearance
Clearance is the distance from the road to the platform. The greater the clearance, the more free space between the road and the base of the scooter. With an increase in clearance, it becomes possible to ride on inclined surfaces, that is, descents and ascents. With low ground clearance, the platform will rub against the road if you drive on inclined surfaces. Scooters with high clearance open up great features for the rider in the field of stunt and sports riding. The clearance is affected by both the diameter of the wheels and the height of the wheel mounts.
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.
