Comparison Kugoo Kirin S1 Pro vs Kugoo S3

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.

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 type of drive in the design of the scooter determines to which wheels the traction from the electric motor is transmitted.

- Front. The drive to the front wheel pulls the entire electric scooter. It provides improved stability on the road, minimizes the likelihood of skidding in corners, and guarantees a soft start and smooth acceleration. On the other hand, the electric motor at the front increases the weight of the wheel assembly and increases the effort when turning the handlebar.

- Rear. Rear-wheel drive electric scooters are not as stable on the road as front-wheel drive models. However, they are more frisky, demonstrate dynamic acceleration and easily conquer hills.

- All-wheel. Scooters with all-wheel drive combine all the positive qualities of front- and rear-wheel drive models in one package. They are also best suited for off-road driving — the all-wheel drive chassis does not care about pits and steep hills, other road irregularities, or mud deposits on the road.

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.

Like a handbrake, the rear brake can be drum, electric, or disc. In addition, there may still be a classic foot brake, as in ordinary scooters, or not at all.

— Disk. The disc brake on the rear wheel ensures a quick stop of the scooter. These 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 type brake has above average efficiency. The drum brake makes the rear wheel massive and heavy. 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, the complexity of maintenanc...e.

- Foot. The simplest kind of clamping type brakes, which involves slowing down and stopping the scooter by pressing your foot on the fender of the rear wheel. Note that this is the least efficient braking system of the existing options.

- Electric - braking with the help of recuperation. 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. The electric type 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.

- Absent. The rear wheel is not equipped with a brake. In this case, the braking system is provided 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.

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.

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.

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”.

The ability to change the height of the handlebar, adjusting it to the height of the user. This feature will be especially useful if the scooter is bought for several users of different heights or for a teenager who is still in the growth stage.
