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).
Rear brake
— No brake. The rear wheel is not equipped with a brake. In this case, the braking system may be provided at the front. However, some scooters do not have brakes both at the rear and at the front. The advantage of scooters without a rear brake is that the vehicle will not skid to the side when braking actively when cornering. Scooters without brakes, both front and rear, are mostly the simplest children's models that do not accelerate to a dangerous speed. In this case, braking occurs either by reducing the overrun or by kicking the ground.
— Rim. Rim brakes slow and stop the scooter by pressing the pads against the wheel rim. The rim brake system has an average efficiency. Usually, the scooter stops gently and smoothly. The rim brake is most often installed on the rear wheel of the scooter. The soft brake prevents the vehicle from skidding when braking on turns. Rim brakes are good because they have a simple design. This kind of braking system is easy to maintain. The weak point of rim brakes is a sharp decrease in efficiency when moisture enters the rim.
— Disk. The disc brake on the rear wheel ensures a quick stop of the scooter. This type of braking system is designed more for sports and stunt scooters that often need to quickly decelerate at high speed. But the disc brake can also be found in pleasure, as well as city boards. Disc brakes have a short-stroke friction clutch. Due to the small distance between the pads and the disc, the friction...clutch very quickly comes into contact with the working surface of the brake disc. In this case, the friction clutch is pressed against the disk with a sufficiently large force. The disc brake allows the scooter to stop extremely efficiently. But when using a disc brake on the rear wheel, you should be careful, because when braking hard, especially when cornering, the scooter can skid to the side.
— Drum. The drum brake has above-average efficiency. The drum brake makes the rear wheel massive and heavy. For this reason, scooters with a drum brake system are rarely used as a stunt and sport scooters, but there are exceptions. Urban models are often equipped with a drum-type brake. This type of brake has a closed design. The pads are inside the wheel. Friction linings rub against the inner surface of the rim. Access to the drum brake is closed by a protective cover. Thanks to the closed design, neither moisture nor other blockages get inside the brake drum, which makes the brake operation more reliable and trouble-free. Among the shortcomings can be noted an increase in the dimensions and weight of the wheel and the complexity of maintenance.
— Electric Electric brake is used on electric scooters. The brake system of this type makes the stop extremely soft, slowing down occurs when the speed of the electric motor decreases. The rear location of the electric brake assumes that the electric motor is mounted on the rear wheel. The presence of an electric motor makes the wheel massive, it is difficult to use such scooters for stunts or sports riding, although the engine allows you to quickly pick up and hold speed for a long time. The electric brake system is highly reliable and durable, it does not require maintenance. But if the battery pack on the scooter runs out, the electric brake will not work. For such cases, an additional mechanical (hand or foot) brake is usually provided.
