Max. speed

A high top speed gives you more riding options and reduces travel time. However, it requires powerful motors and capacious batteries, which affects the price and weight of the scooter. In addition, the faster the scooter, the more careful you need to be when driving. Therefore, most of the electric scooters have a speed of 25 km / h or a little more - 30 km / h.

Max. climbing angle

The maximum climbing angle that an electric scooter can overcome on engine power alone, without the help of legs. Models with engines of the same power may differ in this indicator (due to the difference in torque and wheel size).

Note that in the specifications the angle is usually indicated in degrees, while on road signs it is given as a percentage (1% corresponds to a rise of 1 m for every 100 m of horizontal movement). However, this moment is not particularly critical: if you often have to overcome a certain hill, you can clarify its slope by converting percentages into degrees (and vice versa) according to special tables. In addition, if the angle turns out to be too large, nothing prevents you from helping the scooter with your foot, in extreme cases, to overcome the climb on foot.

Wheels

The type and size of wheels used in an electric scooter.

The size is selected by the manufacturer depending on the general purpose of the scooter - whether it is an asphalt road or rough terrain. If we compare similar models with different wheel diameters, then it is worth considering that the larger the wheels, the better they work out the bumps in the road, the higher the cross-country ability and softness of the ride. And small wheels, in turn, are great for smooth asphalt and dynamic driving, they easily accelerate and allow you to make sharp turns.

As for the different types of wheels, there are polyurethane, rubber, inflatable. More about each:

- Polyurethane. Wheels with solid polyurethane tyres. This material provides good cushioning, high-quality grip and at the same time good rolling; it is resistant to temperature extremes and damage, durable, while it is inexpensive.

— Rubber. In this case, we mean wheels with a solid rubber tyre (inflatable wheels are moved to a separate pick-up point). According to the main characteristics, rubber is similar to the polyurethane described above, and in some moments even surpasses it. So, such tyres do not make noise, smooth out the roughness of the asphalt well, have excellent grip and provide high braking efficiency. On the other hand, this material is less durable and does not tolerate temperature extremes.

— Inflatable. The most advanced type of wheels found in modern...scooters. Wheels of this type have an inflatable tyre (as in bicycles), which provides excellent shock absorption, tight grip and high flotation. The disadvantages of inflatable tyres, in addition to the price, include sensitivity to punctures and increased maintenance complexity: you need to monitor the pressure and, if necessary, inflate the tyre.

Front brake

Among the various types of brakes in scooters, you can find rim, disc, drum, electric. There are also models without a front brake.

- Rim. The rim brake is considered the simplest type of braking system. Such brakes provide a smooth deceleration and a complete stop of the scooter at an average speed. The stopping distance is usually medium or long. The rim brake is represented by pads, which, using a special mechanism, are pressed against the wheel rim. The pads themselves are driven by a lever, which is placed on the handlebar. Among the advantages of a rim brake are low price, and simple design. And drawbacks are fairly quick wear of the pads and the need to adjust the brakes as the friction linings wear out. Additionally, when using a scooter with a rim brake, be aware that the pads become less grippy if the rim is wet. In rainy, cloudy and slushy weather, the rim brake cannot be relied upon.

— Disk. Disc brakes are considered more advanced than rim brakes. The disc brake allows the scooter to stop quickly enough, and the braking distance itself can be either minimal or medium. Such brakes are represented by a friction clutch that acts on a small-diameter disc. The disc is attached to the wheel axle. The clutch is pressed against the brake disc with a sufficiently large force, which allows the disc brakes to b...e effective even when wet on the clutch. The disc brake is controlled by a lever that is placed on the handlebar. The advantages of a disc brake for a scooter are reliability, durability and the ability to stop quickly. Among the shortcomings, we highlight the high price and the need to adjust as the friction clutch wears out.

- Drum. Drum brakes slow down well and provide a fairly quick stop. In terms of efficiency, the drum brake for a scooter is between the rim and disc brake systems. The drum brake uses pads that are located inside the rim. In this case, the friction plates act on the inside of the rim. The brake with a drum device has many advantages: a large friction contact surface, moisture protection, reliability and durability. Among the shortcomings can be noted: the use of massive wheels, the complexity of service maintenance, and the need for periodic adjustment.

- Electric — braking with the help of recuperation. In this case, the deceleration and stop are produced by the electric motor itself, by reducing the speed. Usually, the electric brake provides a soft and smooth stop. As a rule, the electric brake acts as an auxiliary brake system. Also, advanced scooters often use a recuperative electric brake. In this case, when the speed is slowed down, energy is recovered, which allows you to recharge the battery pack.

- No brake. The front wheel is not equipped with a brake system. The braking can only be provided at the rear.

Suspension

The presence of a suspension makes the ride more comfortable, smoothing out vibrations and shaking when moving on an uneven roadway, but reduces control accuracy. - Front. In models with such shock absorption, the corresponding dampening device is installed only on the front wheel, while the rear wheel is rigidly fixed. Electric scooters with a front shock absorber combine good handling and provide comfortable movement on bad roads or over rough terrain.

- Front and rear. An advanced type of shock absorption system on both wheels of an electric scooter. Models with double cushioning are the best at damping the vibrations felt by the rider and providing proper traction on rough trails.

- No suspension. In electric scooters without suspension, the wheels are rigidly attached to the frame. This design is simple. However, the rider feels all the bumps of the road in full.

Cruise control

A feature that allows you to ride the scooter at a preset speed without having to hold down the throttle button. Cruise control is a convenient option when travelling over long sections of the route while maintaining a constant speed.

App control

Wireless pairing of an electric scooter with a smartphone is usually carried out via Bluetooth. Synchronization with a mobile device allows you to control many functions of the scooter, switch riding modes, block the engine, track mileage, keep control of the range and battery status. Also, the smartphone application usually displays trip statistics: mileage, average speed, distance covered, etc.

Brake lights

The classic brake light is a red tail light that illuminates when the brakes are applied to warn road users behind that the scooter is slowing down. This feature is especially useful when driving on public roads - warning others about braking in such conditions is never superfluous.

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 electric scooter. With an increase in clearance, it becomes possible to travel on inclined surfaces, i.e. up and down. With low clearance, the platform will rub against the road if you drive on inclined surfaces. The clearance is affected by both the size of the wheels and the height of the wheel mounts.
