Range
The maximum distance that an electric scooter can travel on a single battery charge.
Usually the range is indicated for a flat road and driving only on an electric motor, without the help of a rider. So this indicator is quite conditional, in practice, the distance of the trip may be either less or more, depending on the characteristics of the road and driving style. Nevertheless, according to the claimed range, it is quite possible to estimate the autonomy of different models and compare them with each other.
Note that a
large range (more than 50 km) requires capacious batteries, which affects the dimensions and weight of the device. The real need for such autonomy is not required so often, especially since many electric scooters are quite capable of driving in the usual way, without the use of an electric motor.
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 (
10" and
larger), the better they handle road unevenness, the higher the cross-country ability and softness of the ride. And small wheels (for example,
8") in turn, they are excellent for smooth asphalt and dynamic driving; they accelerate easily and allow you to make sharp turns.
As for the different types of wheels, there are
polyurethane,
rubber,
inflatable. More details about each:
- Polyurethane. Wheels with solid polyurethane tires. This material provides good shock absorption, high-quality road grip and at the same time good rolling ability; it is resistant to temperature changes and damage, durable, and inexpensive.
— Solid rubber. In this case, we mean wheels with solid rubber tires (inflatable wheels are taken to a separate selection point). In terms of its main characteristics, rubber is similar to the polyurethane described above, and in some respects even surpasses it. Thus, such tires do not make nois
...e, smooth out asphalt roughness well, have excellent grip and provide high braking efficiency. On the other hand, this material is less durable and does not tolerate temperature changes well.
— Rubber inflatable. The most advanced type of wheels found in modern scooters. This type of wheel has an inflatable tire (like a bicycle), which provides excellent shock absorption, tight traction and high maneuverability. The disadvantages of inflatable tires, in addition to the price, include sensitivity to punctures and increased difficulty in maintenance: you need to monitor the pressure and, if necessary, inflate the tire.
— Rubber gel. Tubeless wheels filled with gel are insensitive to minor punctures and cuts. Coming out, the gel in the tire hardens almost instantly upon contact with air, effectively sealing the damaged area. In addition, such wheels require virtually no maintenance - they do not need to be inflated. The disadvantages of gel tires include their high cost and somewhat greater rigidity than inflatable tires (although such wheels are still noticeably superior to rubber wheels in terms of softness).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 electric scooter has a shock absorption system – it makes the ride more comfortable, smoothing out vibrations and shocks when moving on uneven road surfaces, but reduces the rolling ability and control accuracy.
–
Only front. In models with such shock absorption, the corresponding device for damping irregularities is installed only on the front wheel, while the rear wheel is fixed rigidly. Electric scooters with a front shock absorber combine good handling and provide comfortable movement on bad roads or over rough terrain.
–
Only back. Electric scooters in which only the rear wheels are shock-absorbed, while the front wheels are rigidly fixed. The rear shock absorber is designed to provide additional comfort when encountering various uneven road surfaces, but it is often inferior in efficiency to the front one.
—
Front and rear. An advanced type of shock absorption system on both wheels of an electric scooter. Dual-shock models are best at dampening vibrations felt by the rider and providing adequate traction on rough trails. At the same time, double depreciation reduces the rolling of the scooter to the greatest extent.
—
No Suspension. In electric scooters without shock absorption, the wheels are rigidly attached to the frame. This design is simple, and the corresponding models have a
...good roll. However, the rider feels the entire terrain of the road in full.Battery capacity
Battery capacity installed in the electric scooter.
Theoretically, a higher battery capacity allows for a longer range, but in fact, not everything is so clear. Firstly, motors of even the same power can differ in efficiency; secondly, the actual amount of energy stored in the battery depends not only on the capacity in amp-hours but also on the voltage in volts. So this parameter is secondary, and when choosing, it is worth focusing not so much on the battery capacity, but on the directly claimed range. You can compare capacity only for models with similar characteristics and the same supply voltage.
Full charge time
Time to fully charge the battery from zero to 100%.
The more powerful the device, the more capacious batteries it needs and, as a rule, the longer the charging time. In the heaviest models, it can reach 20 hours. However, such indicators are rare - most electric scooters are charged for a maximum of 8-9 hours, which allows you to put the device on charge “from evening to morning”.
