Kukirin G4 Electric Scooter Review: heavy, fast, and built more for power than comfort

I’ve been riding the Kukirin G4 for a bit now, mostly for commuting across town and a few longer weekend runs. If you’re imagining a light little city scooter you can carry up stairs, forget it. This thing is a 35.5 kg beast. First impression when I unboxed it: it looks and feels closer to a compact electric moped than a casual scooter you fold and throw in the trunk every day.

In practice, it’s clearly built around power and range on paper: 60V 20Ah battery, claimed 75 km range, 11-inch tubeless tyres, dual suspension, dual disc brakes. On the listing, it all sounds very impressive. But once you actually ride it, you see where the marketing numbers meet reality. The scooter can go fast and feels quite solid on straight roads, but the range and practicality depend a lot on your weight, riding style, and where you live.

Also, keep in mind: it’s officially meant for private land, not public roads. So if you’re buying this thinking you’ll daily it through city traffic legally, that’s not what the brand is saying. I mostly used it on private roads, industrial zones on weekends, and some large private parking lots where I had permission. For that kind of use, it makes more sense.

Overall, my first takeaway is simple: the Kukirin G4 is for people who want a strong, long-range style scooter and don’t mind the weight and bulk. If you need something you can easily carry, store in a flat without a lift, or drag up three floors, this is going to be a pain. But if you’ve got a garage, a garden shed, or ground-floor storage, then it starts to look a lot more interesting.

In terms of value, the Kukirin G4 sits in that segment where you’re paying more than for a basic commuter scooter, but you’re also getting more power, bigger tyres, and better brakes. Some Amazon buyers mention they got it at the cheapest price they could find for a new one and seemed happy with what they received. I’d say for what it offers – 60V battery, dual disc brakes, 11-inch tubeless tyres, suspension – the price is fairly reasonable, as long as you’re actually going to use those features.

If you only need a scooter for short, flat city rides at moderate speed, this is overkill. You’d be paying for power and weight that you don’t really need, and you’d probably be better off with a lighter, cheaper model that folds easily and has a more realistic range for urban commuting. The G4 makes more sense if you want something that can handle rougher private terrain, longer straight runs, or heavier riders without feeling flimsy.

The main thing that hurts the value slightly is the gap between claimed and real-world range. The specs say up to 75 km, but user feedback and my own experience suggest a lot less for a normal adult riding at decent speeds. So if you’re buying it purely for range, you may feel let down. If you’re buying it for performance and stability and you’re okay with 25–40 km of honest range, it suddenly looks a lot better.

Overall, I’d call the value good but not mind-blowing. You get strong performance, solid construction, and serious components for the price, but you also have to live with the weight, the long charging time, and a range that doesn’t quite match the marketing. If those trade-offs sound acceptable for how you plan to use it, then it’s a decent deal. If not, you might want to look at lighter, more commuter-focused scooters instead.

The design of the Kukirin G4 is clearly geared towards people who like a more aggressive, rugged look. The frame is big and chunky, with a wide deck and those 11-inch tyres that immediately make it look more serious than the usual rental-style scooters. When it’s parked next to a typical city e-scooter, it looks like the big brother that goes to the gym. It’s not discreet, and you’ll get looks, especially if you ride it in areas where people are used to smaller models.

The folding system is functional but not exactly light or quick. It folds, yes, but with 35.5 kg to move around, don’t think of it as something you’ll fold and carry into the office every day. For me, folding is mainly useful to fit it in the boot of a car or to store it in a corner of the garage so it doesn’t take up as much space. The handlebar height is around 99 cm, which felt comfortable for me (I’m around average height). Taller people might still be okay, but it’s worth checking measurements if you’re very tall.

The touch display on the handlebar is a nice idea. It shows all the key info – speed, mode, battery – and is easy enough to read. That said, in bright sunlight it can be a bit hard to see, and I personally worry a bit about a touch surface on something that can get wet, dirty, and shaken around. So far, it’s held up, but I wouldn’t poke it with wet or muddy gloves. Buttons would be more basic but probably tougher long term.

Lighting-wise, it’s got a front light, rear light, brake light, and turn indicators. That’s useful in low light, especially on private roads or large yards. Just don’t expect car-level visibility. The build feels solid overall, with a kind of industrial vibe. Not pretty, but practical. If you like minimal, sleek designs, this is not that. If you like something that looks like it means business, it fits that role quite well.

The battery is one of the main selling points: 60V 20Ah with a claimed 75 km maximum range. That sounds huge, and technically the capacity is indeed large compared to many cheaper scooters. But the range depends heavily on rider weight, speed, terrain, and how often you stop and start. In real life, with a normal adult using it in a mix of modes, you’re not hitting 75 km unless you ride very gently on flat ground at low speed.

One of the Amazon reviewers at around 83 kg reported roughly 20 km in eco sport mode, which is pretty short for a battery of this size. In my case, with mixed riding and not trying to save power, I was somewhere in the 25–35 km range per charge. If I deliberately took it easy, I could push it further, but it still didn’t feel like the 75 km claim was realistic for everyday use. So yes, the battery is big, but the scooter is also heavy and powerful, which eats into that capacity quickly.

Charging time is around 11 hours, which is long. This is the kind of scooter you charge overnight, not something you top up quickly during lunch. You also need to be a bit disciplined with battery care. The brand insists on using the official charger and following the manual, and I agree with that. With a big battery like this, it’s better not to leave it completely empty for days or constantly at 100% for weeks. Try to store it around mid-charge if you’re not using it for a while.

Overall, the battery is decent but not magical. It gives you enough juice for medium-length rides with strong performance, but if you were dreaming of doing full-day rides at high speed without worrying, that’s not what happens here. Think of it as a powerful scooter with a reasonable real-world range, not a long-distance touring machine despite what the marketing number suggests.

In terms of comfort, the Kukirin G4 is a bit of a mixed bag. On the positive side, the 11-inch tubeless tyres and dual suspension really help on rougher surfaces. On grass, compacted paths, and slightly broken tarmac, it feels much more comfortable than the small-wheel scooters I’ve used before. You don’t get that constant rattling in your wrists and knees. The deck is wide enough to stand with your feet staggered, which is more comfortable for longer rides.

However, the weight is always there in the background. At 35.5 kg, the scooter feels heavy when you’re manoeuvring at low speed or pushing it around by hand. Tight turns in small spaces feel a bit clumsy compared to a lighter scooter. If you live in a flat and have to haul it through narrow hallways or up steps, you’re going to swear at it pretty fast. I mainly rolled it straight out of a garage, and even then, moving it around without power isn’t fun.

While riding, the stability is good, especially at medium speeds. The wider tyres give decent grip and balance, so you don’t feel like you’re standing on a toothpick. On the other hand, the scooter’s size and power make it feel a bit overkill for short, stop-start city commutes where you’re constantly braking, turning, and hopping off. It’s more at ease on longer stretches where you can keep a steady speed and let the suspension and tyres do their job.

Overall, comfort is solid once you’re rolling, but everything around that – moving it, storing it, lifting it – is where it becomes tiring. If you’ve got good access (garage, lift, ground-floor storage), you’ll probably be happy with the ride. If you’ve got stairs or cramped storage, the comfort you gain on the road, you’ll lose in your back and shoulders every time you move it.

From a build-quality point of view, the Kukirin G4 feels pretty solid. The aluminium frame is thick, the deck doesn’t flex under normal adult weight, and the overall construction gives you a sense of robustness. When riding, there are no weird creaks or wobbles, and the folding mechanism, while not the smoothest, locks in with a reassuring feel. A couple of Amazon reviewers mention that there are no cheap-feeling parts and that it feels solid, and I’d agree with that first impression.

The IP54 rating is fine for light splashes and dust, but I wouldn’t push it in heavy rain or deep puddles. It’s a big, expensive battery and a touch display – not exactly things you want to drown. I rode it on damp ground and through a bit of surface water without any drama, but I avoided riding in proper downpours. If you live somewhere very rainy, you’ll need to be careful and probably treat it more like a fair-weather machine.

The tubeless tyres are a good point for durability. They reduce the risk of pinch flats compared to inner tubes, and they can handle rougher surfaces better. Of course, you can still get punctures, but in general, they should be less of a headache than tube tyres. The dual suspension also helps protect the frame and your joints from constant shocks, which should be good for long-term use if you’re riding on mixed terrain.

Long-term, the parts I’d watch are the touch display, folding mechanism, and battery. Touchscreens and outdoor use don’t always age well together if you’re rough with them. The folding joint should be checked regularly and tightened if needed, like with any folding scooter. The battery will naturally lose capacity over time, especially if you don’t follow good charging habits. The 12-month warranty is okay, but don’t expect miracles if you abuse it. Overall, it gives a solid impression, but it’s still an electric scooter – not a tank. Treat it decently and it should last, but it’s not maintenance-free.

Performance-wise, the Kukirin G4 is clearly not a toy. The 60V system gives it strong acceleration compared to the typical 36V commuter scooters. You feel it as soon as you push off and hit the throttle – it gets going quickly, and on private stretches of road it’s easy to reach speeds that feel more like a small moped than a kids’ scooter. If you’re used to rental scooters, this will feel like a big step up in power.

The dual disc brakes do their job pretty well. You get decent stopping power and more confidence at higher speeds. I still recommend adjusting your riding style and not relying on emergency braking all the time, but for normal use, the braking system felt solid and predictable. The combination of big tyres, suspension, and real brakes means you feel more in control than on the flimsy budget models with tiny drum brakes.

Where the performance gets a bit disappointing is the range versus expectations. The brand advertises up to 75 km, but that’s clearly under very gentle conditions (light rider, low speed, flat ground, eco mode). One Amazon review from an 83 kg rider mentioned only getting about 20 km in eco sport mode, which is a big gap. My experience was in the middle: I’m not super light, rode a mix of speeds, and I was nowhere near 75 km. If you ride fast and you’re not a featherweight, you should mentally plan for more like 25–40 km of real-world range, depending on terrain and how hard you push it.

So in practice, the performance is good in terms of speed and feeling of power, but the battery drains quicker than the spec sheet might make you think. If you’re okay with charging more often and mainly want the extra punch and stability, you’ll be happy. If you’re buying this purely for super long range at high speed, you may feel a bit misled by the numbers on the box.

On paper, the Kukirin G4 ticks a lot of boxes. You get a 60V 20Ah lithium battery, which is pretty big for a scooter in this price range. The brand claims up to 75 km of range under ideal conditions. There’s a touch display that shows speed, battery, mileage and riding mode. You also get front and rear disc brakes, dual suspension, and 11-inch tubeless tyres. It’s IP54 rated, which means it handles light splashes, but it’s not something I’d ride in heavy rain on purpose.

The scooter is foldable, frame is aluminium, wheels are rubber, and the whole thing weighs about 35.5 kg

Out of the box, you basically get the scooter and the charger. No fancy extras, no big toolkit. The warranty is 12 months, but as usual, wear and tear or misuse are not covered. That’s pretty standard. I strongly recommend reading the manual about charging and storage, because big batteries like this can degrade quickly if you leave them flat or constantly full. The brand mentions a smart BMS, but that doesn’t mean you can abuse it without consequences.

In short, in terms of features, it’s a pretty solid package for someone who wants power, big tyres and real brakes. It’s not a gadgets-and-bluetooth toy, it’s more of a serious electric scooter for adults. Just don’t expect miracles on range if you’re heavy and ride fast, because as one Amazon review pointed out, the real-world numbers can be far from the 75 km promise.
