Max. speed
The maximum speed that the car can develop under normal conditions is on a flat road with good coverage.
This indicator is directly related to the age category: the older the child, the more speed he needs. So, models for babies under 3 years old usually go no faster than 4 – 5 km/h — this ensures safety and allows the parent to keep up with the machine without any problems; and some teenage
ATVs(age category from 7 to 8 years old) are capable of accelerating to 30 km/h or even more.
There are cars with speed limiters to make driving safer; see "Options" for details.
Climbing
The maximum climb that an electric car can overcome. The angle of elevation in this case is indicated in the same way as in road signs — as a percentage, that is, how many metres the road will rise when passing 100 m: for example, 12% means a rise of 12 m for every 100 m of the path.
Note that this indicator is not related to either the maximum speed or the age category; moreover, among simple and slow cars for younger age there are models that can overcome quite significant rises — 15% or more. In general, it makes sense to pay attention to this parameter in cases where you plan to travel frequently in areas with an abundance of ascents and descents.
Voltage
The nominal voltage of the battery installed in the machine.
When selected, this parameter is of secondary importance: it can be useful when comparing several models in terms of battery capacity (see above), but it practically does not affect the performance of the machine. In addition, battery voltage data may be needed to find a spare battery or non-original charger.
Power
The power of the electric motor installed in the electric vehicle; if there are several engines, their total power is usually indicated.
The more powerful the engine, the faster and/or passable the machine will be, the steeper climbs it will be able to take and the easier it will be to cope with more weight, all other things being equal. At the same time, a powerful motor has a high power consumption and requires more capacious and powerful batteries, and this parameter significantly affects the cost. In general, we can say that for an ordinary user, power is rather a secondary parameter: when choosing an electric car, it is more convenient to look at the directly claimed speed, carrying capacity and other practical characteristics.
