After the recently tested KuKirin G2 Master electric scooter, we have another new model from the same manufacturer—KuKirin G4. It’s a higher-end line with roughly the same motor power, a better battery, and a more massive build.
In this review, we’ll again take a close look at the build quality, examine the individual components in detail, and evaluate the overall riding experience. Last but not least, you’ll also find a real-world range test on a single charge.

Packaging contents & quality
The KuKirin G4 scooter was delivered by the SPS courier in a double box with dimensions of 1310 x 300 x 615 mm and a total weight of up to 43 kg. Inside the box, you’ll find the scooter in the folded position, with the handlebars and the rear fender removed.
Unlike e-bikes, you won’t deal with any lengthy assembly here. You just unfold the scooter, attach the handlebars to the stem using two screws, and also fix the rear fender using a pair of screws.
The keys needed for these steps are included in the package, along with the manual and the charger.
To prevent the scooter from getting damaged during transport, it’s protected by several shaped polystyrene pieces. Unfortunately, they crumble, so we had polystyrene scattered all over the scooter. If you unpack the scooter indoors, we recommend having a vacuum cleaner on hand for the polystyrene.
Overall, the scooter is packaged well, even though instead of polystyrene we’d prefer foam braces that don’t create unnecessary mess.
A high-quality and extremely robust scooter
Electric scooters with similar power (2000 W) are usually already among the more heavy-duty models, but the KuKirin G4 has an even more solid frame than we expected. Compared to the KuKirin G2 Master—still fresh in our memory since we recently tested it—the G4 model is significantly more robust.
The scooter keeps the brand’s colors, so it’s black and orange. Its frame is made of an aluminum alloy, and the design choice is definitely a success.
Whether it’s the handlebar stem with its interesting design, the wheel mounts, the foot platform, or the wheels—everything looks massive at first glance. That’s also reflected in the scooter’s weight, which is 37 kg. So it’s a pretty heavy machine, even though it has its downsides.
It’s hard to carry the scooter up and down stairs, because there’s really nothing solid to grab onto. When folded, we usually hold it by the main steering stem, but here it’s too sharp and angular, so it’s uncomfortable to hold in your hand.
When the scooter is folded, we typically grab it with one hand somewhere above the front wheel area, and with the other hand by the rear footrest. In this case, though, there’s no handle at all, and the end piece is rather slippery. The most natural way was to hold it with your right hand by the rear light underneath the footrest mentioned above, but since it’s plastic, it’s not the best option.
As for dimensions, the rubberized foot platform measures 51 x 22 cm, the handlebars are 129.5 cm above the ground, and the scooter’s total length is 133.6 cm. The handlebar height is just right for us (the editor is 185 cm tall). They’re not height-adjustable, but on the other hand they’re at least sturdier and more stable.
Handlebars with a large touch display
The handlebars are 66 cm wide, with fairly soft rubberized grips and a large LCD display in the center. It shows the current speed, riding mode, total mileage, battery capacity, the KuKirin logo, and a trio of touch buttons.
The Mode, Light, and Set buttons are used to switch between riding modes, turn the lights on or off, and switch between speed units (km/h or mph).
The display isn’t the best in strong sunlight, but at least the current speed is clearly visible. Our biggest concern is the battery capacity display. Once again, you only get a graphical indicator—up to ten segments inside the battery icon. We’d much prefer a voltage readout in volts.
The graphical indicator can be misleading and not very precise—you just have to get used to it. Also, since there are up to 10 segments, at higher speeds they’re not the easiest to read.
Let’s move on to the components on the handlebars. On the left side, the manufacturer placed a rear brake lever and a turn-signal controller with a horn. On the right side, there’s the front brake lever together with the throttle lever.
Power and riding modes
The KuKirin G4 isn’t trying to be some kind of urban scooter capped at 25 km/h. Its 2000 W motor is mounted at the rear and reaches a maximum speed of 70 km/h—at least according to the manufacturer.
In reality, we only reached that speed when riding downhill. Even on a long straight, the top speed was “only” around 64 km/h. According to GPS, it was another 4 km/h less. It’s not that it’s bad, but it isn’t common for a scooter to fall short of the manufacturer’s claimed speed.
Still, the power is enough—the scooter accelerates nicely and smoothly. It’s not some kind of asphalt shredder or a scooter that jerks at launch, but the performance is just right.
It offers three riding modes with maximum speeds of 20, 40, and 70 km/h. As we already mentioned, it won’t hit 70, but the lower speed steps are accurate, based on the stated figures.
The maximum claimed incline of 20° is, in our opinion, too optimistic. In steep hills, the scooter naturally slows down, and on long climbs it really has to work. It handles them quite well, but it definitely won’t manage a 20° incline.
Wide tires and comfort during the ride
The electric scooter KuKirin G4 has properly wide 11″ tires with a tire size of 90/65 – 6.5. It’s sold with a road tread, but it also does fine on lighter terrain like dirt paths and farm tracks.
Thanks to its tread pattern, the scooter is exceptionally quiet on asphalt—though that also has a small downside – people nearby can’t hear you coming too well. As for suspension, we’ve got both front and rear spring shock absorbers. The scooter absorbs bumps really well, but sometimes it’s almost too soft, and when riding over larger irregularities—especially at higher speeds—we often hit the shock absorber’s limit, where you can hear a clunk.
So we rode with the scooter in pretty good comfort overall. We also appreciate the rear footrest/grip, where you can comfortably rest your foot if you want to change your riding stance.
Good brakes, but weaker lighting
With scooters like these, we automatically expect quality disc brakes. In this case, the manufacturer chose mechanical, cable-actuated brakes, so at first we were skeptical—yet they surprised us. Even though they’re not hydraulic, the levers squeeze easily and the brakes bite really well. KuKirin G4 is proof that cable-actuated disc brakes can be great.
As we already mentioned earlier, the scooter has turn signals in addition to the standard lights. They’re placed not only at the rear, but also at the front. Unfortunately, just like in other cases, the indicator lights aren’t very easy to see, and especially during the day we definitely wouldn’t rely on nearby drivers noticing them.
The front turn indicators sit at the edge of the front white light, which is covered by a relatively large casing at the level of the display on the handlebars. It should also serve as a kind of screen/shield for the display. The rear turn indicators, on the other hand, are built into the rear red light.
Even the mentioned front light isn’t particularly bright, and when riding in complete darkness, you’d definitely want better illumination.
Battery and range
Let’s move on to one of the most anticipated categories: the battery and range on a single charge. The KuKirin G4 comes with a 60 V / 20 Ah battery, which is stored very securely in the chassis together with a 40 A controller that, according to everything, uses sinewave and offers a smooth start-up curve.
The manufacturer claims a range of up to 75 km on a single charge without any additional details. As is usually the case, such a range isn’t really that realistic, and in most cases we only manage a little over half of the manufacturer-stated range.
We conducted the range test on a single charge with an 80 kg rider in the highest mode. We set off from Košice into the surrounding area, and for the first roughly 23 km we rode almost constantly at full power through the nearby villages. The terrain was slightly hilly. We then returned to the edge of the city, where we alternated between faster and slower riding, always in the highest Race mode.
Overall, we covered 38.58 km, and we ended the ride when the last battery segment had been lit for some time, which should correspond to around 10% capacity. We measured the range using a smartphone with the Runkeeper app.
You won’t be happy about long charging with a 2 A charger. It takes up to about 11 hours.
KuKirin G4: Final assessment
If you’re looking for a stronger, well-built, heavy-duty scooter, the KuKirin G4 is definitely an interesting choice. Right away, it impresses with its high-quality and exceptionally massive construction, along with wide tires.
It has a 2000 W motor at the rear, which allows it to reach a maximum real-world speed of up to 60 km/h. It’s comfortable, well-suspended, and delivers very good ride characteristics, with a comfortable riding stance thanks to the wide platform and the rear foot pedal.
You’ll also appreciate the 60 V / 20 Ah battery and quality disc brakes. What’s a bit disappointing, though, is the very long charging time and the higher weight. Because of that, and because there’s no handle to grip it above the rear wheel, the scooter is hard to carry—for example, up stairs.
All in all, though, it’s a very well-built scooter for those who want faster riding and a solid build quality for a reasonable price.
If we’ve convinced you, you can find the Electric scooter with our long-time partner Banggod, who also provided it to us for testing.

Discussion (2)
Even though the suspension is probably a bit too soft. It would be great if you could adjust the hardness. Otherwise, the ride characteristics are really good. I got 73 km/h out of it; I weigh 80 kg. I live on a large flat plain before anyone says that I rode downhill or into a ravine…
I have over 2,500 km on it, and it gets me 70–72 on the flat just fine if there’s no headwind. Plus, since I’m about 60 kg, it loves me 🤣 You don’t have to stand on it like a plank, but position yourself so there’s as little wind resistance as possible.
