The logical question to ask is therefore this: what is this 4e model of the “Kirin S” line has more than its predecessor? Complete decryption in this test.

Kugoo Kirin S4 scooter: construction and design

The rule would be that a new model of a series has more interesting characteristics than the previous generation. When it comes to design and aesthetics, does the Kugoo Kirin S4 differ from the Kugoo Kirin S3 Pro?


On the question of dimensions, the Kugoo Kirin S4 has undergone a clear evolution compared to a Kirin S3 Pro. Indeed, the new unfolded model is 119 cm long, 53 cm wide and 109 cm high. While it is longer and wider, its height is down from its predecessor. Which isn’t unpleasant though.

Being a foldable model in length, the scooter increases to 43 cm in length when folded. This change in dimensions earned it a weight increase of 11 to 13.5 kg, compared to the previous generation, i.e. 2.5 kg more. It should still be noted that this is a waterproof model with a protection index of IP54. It is attributed to any equipment protected from limited dust infiltration and liquid splashes “. A rather interesting point!

10 inch pneumatic tires

In terms of the tires of the Kugoo Kirin S4 electric scooter, the major evolution concerns the size of the wheels. It goes to 10 inches, while it was 8 inches for the Kugoo Kirin S3 Pro. Does this difference have any impact on the ride quality of the scooter? Absolutely !

Indeed, larger wheels ensure a better grip of the device. Not only is the level of comfort significantly improved, but driving is also much safer. It has a strong shock absorption capacity especially when going at full speed over bumps.

The tires have non-slip treads that limit slippage. All this arsenal gives this electric scooter a major interest; its adaptability. Indeed, the device allows you to be comfortable on all types of roads. Since the wheels are of high elasticity, the damping is better.

This makes it possible not to feel the jolts on steep paths, gravel roads, whether smooth or bumpy. These larger wheels, in addition to the more generous dimensions of the scooter, give it the capacity to support up to 100 kg of load against 120 kg for the previous model.

Front and rear headlights

Like the latest generation electric vehicles, the Kugoo Kirin S4 has been equipped with a lamp at the front and a light at the rear. The headlight is designed to offer 3 different lighting modes adaptable to the level of brightness (low, medium, high). In addition to these visual warning devices, there is an audible warning device, a horn, which is used to signal its presence to other users (pedestrians and drivers).

A rear stand

While on the Kirin S3 Pro the side stand is positioned at the front, closer to the front wheel, on the Kirin S4 the manufacturer has decided to position it a little closer to the rear wheel. We wonder if this choice is purely aesthetic or if it has any impact on the user experience of the scooter.

High-tech multimedia equipment

The Kugoo Kirin S4 scooter has been equipped with a high-tech multimedia screen. Equipped with an LED display, it acts as a big touch dashboard. This implies remarkable touch, but above all access to a maximum of driving information in a single display.

In addition to the driving speed of the scooter, the screen displays the speed mode used, but also the mileage, the level of adjustment of the headlights or the level of the battery.


When you order your Kugoo Kirin S4 scooter, it comes with a few accessories, including a charger and a tool kit for possible repairs.

Kugoo Kirin S4 scooter: power and autonomy

What we recognize the quality of a scooter is above all its mechanical arsenal. It is therefore legitimate that we wonder about the equipment of the Kugoo Kirin S4.

motor and battery

For this new generation of scooter, the manufacturer Kugoo has decided to renew the 350 watt motor, with nearly 700 rotations per minute. For this category of electric scooters, this is the best. Thanks to such a motor, the Kugoo Kirin S4 is able to perform high-speed running.

The motor is associated with a 10 Ah battery, compatible with an external load of 36V; this corresponds to a range of 40 km. This battery is rechargeable between 6 and 8 hours. Compared to the previous generation, the Kugoo Kirin S4 has a more autonomous 2.5 Ah battery, since that of the Kirin S3 Pro is only 7.5 Ah.

Speed ​​Modes

In such a small machine as the Kirin S4, the Russian manufacturer Kugoo has decided to place 3 driving modes:

  • the 15 km/h driving mode for journeys in urban areas;
  • the 25 km/h driving mode for journeys in medium-sized urban areas;
  • driving mode at 35 km/h for journeys in low-density areas.

Compared to the Kirin S3 Pro, which also has 3 driving modes, the Kirin S4 stands out with its top speed of 35 km/h compared to 30 km/h for the other generation. The selection of one or the other of the speeds is done from the LED screen which equips the scooter.

Because it’s a Big Touch screen, shifting is as easy as a tap so you don’t have to dwell on settings and focus on driving. This top speed, combined with the power of the motor, allows the scooter to easily perform climbs on sloped tracks with an angle of 15°.

Braking system

The Kugoo Kirin S4 is equipped with mechanical disc brakes. Characterized by actuation by a cable control, this equipment ensures powerful and efficient braking, even when the scooter is rolling in the mud or in the rain. With this system, braking is progressive and therefore safe.

Being an ABS model, it benefits from an anti-lock braking system when you brake. You should know that the machine is equipped with an energy recovery system, which optimizes the autonomy of the scooter.

The Kugoo Kirin S4 in a nutshell

At the end of our review on the Kugoo Kirin S4 scooter, what should we remember?

Good adhesion

By choosing to equip the Kugoo Kirin S4 with 10-inch wheels, the manufacturer has chosen strong grip, which allows for safe driving. Thanks to these wheels, the scooter is able to roll on any type of road. Also, since these are non-slip tires, they are very resistant to wear.

Good autonomy

With a high-capacity 10Ah battery, the Kirin S4 is much more autonomous than the previous version, 40 km against 30 km of running distance in a single charging cycle.

Good braking system

The braking system of this scooter allows safe driving, in particular thanks to the ABS which limits any blocking effect during blocking. Better, it is designed to recover the energy used during braking and convert it into autonomy.
