Comparison Crosser E9 Premium Air vs Xiaomi Mi Electric Scooter 1S

The maximum weight of the rider that the design of the scooter can withstand without breakdowns and accidents. This moment is partly determined by the age group, and mainly by the materials used in the frame. 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. And 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.

The power of the motor installed in the electric scooter. In models with two motors (one per wheel), their total power is usually indicated.

A more powerful motor, on the one hand, has a positive effect on the speed and acceleration characteristics; on the other hand, it affects the cost of the device and requires more capacious batteries, which affect both the price and weight. In addition, at acceleration and low speeds, the scooter can be “helped” by pushing off with your foot. Therefore, in most modern models, the motor power is low — most often in range of 250 W, 300 W, 350 W. Power of 500 W is considered quite high, it allows you to reach speeds of 40 km/h and even higher. In the most advanced models, power is already measured in kilowatts, and the maximum speed can exceed 80 km/h; however, such "monsters" cost accordingly.

However, power also affects the ability to drive a vehicle, because depending on the country, various traffic rules are provided for driving a scooter.

The power in watts that the electric scooter motor can develop at maximum speed. In general, for scooters with an electric drive, it is customary to indicate the rated engine power (see above), which ensures efficient operation of the motor for a long time. By maximum we mean power in the “gas to the floor” mode, achieved only in the short term. Using this parameter, you can roughly estimate the capabilities of a particular model, for example, in terms of speed dynamics - the more power, the faster the scooter accelerates.

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.

The number of speed modes in the electric scooter. By switching between them, the rider has the right to choose the most comfortable pace of the trip and change the upper speed limit bar.

The slowest speed mode (approximately from 0 to 5 – 6 km/h), ideal for use in crowded places, children and beginners. It controls the e-scooter while it moves at a safe speed for pedestrians to avoid collisions on crowded sidewalks. Pedestrian mode is also suitable for leisurely walks and side-by-side trips with walking friends.

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.

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).

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.
