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.
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.
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.
