Fast Answer for Busy Riders ⚡ (TL;DR)
The GOTRAX GMAX Ultra edges out as the better overall package if your priority is straightforward, long-distance commuting on decent roads. Its big LG battery, calm road manners and integrated lock make it the more useful daily tool for riders who just want to get across town and back with minimal fuss.
The NIU KQi 300 makes more sense if your city surfaces are rough, your hills are nasty, and you care a bit more about handling, lights and braking finesse than squeezing the last kilometre out of the battery. It feels more "vehicle-like", but also a bit more overbuilt and less efficient.
If you mostly ride smooth bike lanes and want maximum range per euro, lean GMAX Ultra. If your commute looks like a patchwork of patched tarmac, joints and cobblestones, the KQi 300 will simply hurt you less.
Now, if you have more than five minutes and would like to avoid buyer's remorse, let's dig into how these two actually behave in the real world.
Electric scooters have grown up. Both the NIU KQi 300 and the GOTRAX GMAX Ultra are aimed at riders who are done with rental toys and Amazon specials, and now want something that can take real commuting abuse without disintegrating by autumn.
I've put real kilometres on both: office commutes, late-night suburban runs, the usual "oops, this bike lane is actually cobblestone" surprises. They sit in a very similar price zone, promise "serious" range, and both have that reassuring, non-rattly heft when you first roll them out of the box.
On paper, they're rivals. On the road, they have very different personalities: one is a slightly pudgy comfort-commuter with proper front suspension and brilliant lights; the other is a battery on wheels that just trudges on and on. Let's see where each shines - and where the marketing gloss starts to peel.
Who Are These For, and Why Compare Them?
Both scooters live in that mid-range commuter bracket: not cheap entry toys, not lunatic dual-motor rockets. Think "I'd like to replace a chunk of my car or public transport use" rather than "I just want to pop to the bakery".
The NIU KQi 300 targets riders who want a sturdy, planted scooter that doesn't beat them up on bad surfaces. It feels like NIU shrank one of their mopeds until it fit in a hallway and then stopped there. Best for people whose routes include broken asphalt, tram tracks and the occasional rude pothole.
The GOTRAX GMAX Ultra is the long-haul mule. It's the option for riders whose commutes stretch beyond a quick sprint across town: longer city crossings, campus-to-home runs, multi-stop errand days. It sacrifices outright comfort hardware (no suspension) to stuff a larger battery into a still-reasonable chassis.
Price-wise, they're close enough that you'll almost certainly be cross-shopping them. Same story with weight and top speed class. The real battle is comfort versus range, polish versus efficiency.
Design & Build Quality
Pick up the KQi 300 (or more realistically, try to) and it instantly feels like typical NIU: thick tubing, tidy welds, nothing flapping in the wind. Cables are tucked away, the deck rubber is nicely finished, and the headtube plus suspension fork give it a slightly "serious machine" stance. It's more scooter-as-appliance than scooter-as-gadget.
The GMAX Ultra is surprisingly mature for a brand that built its reputation in the budget aisle. The frame feels solid, the internal wiring job is clean, and the integrated display on top of the stem looks properly modern rather than bolted on. It's maybe a touch less "premium object" than the NIU when you run your hands over the details, but not by a wide margin.
Where they differ is design philosophy. NIU leans into chunky, overbuilt hardware and a front suspension fork - reassuring, but it does leave you wondering if they could have shaved a kilo or two with a bit more restraint. GOTRAX goes simpler and slightly more utilitarian: no suspension, more conventional lines, but then adds nice touches like the integrated cable lock and a very usable, flush display.
In the flesh, the NIU looks and feels a bit more upmarket; the GMAX Ultra looks more understated and practical. Neither is a design disaster, but neither feels truly high-end either. They're competent, grown-up commuters - just with different priorities.
Ride Comfort & Handling
This is where the NIU's main party trick shows up. The hydraulic front suspension combined with fat, tubeless tyres makes a very obvious difference the moment you leave smooth tarmac. Expansion joints, rough patches and those endless micro-cracks that plague city bike lanes get filtered out nicely at the front. Your hands and shoulders notice the absence of constant buzzing.
On the flip side, the rear is still a rigid chunk of metal, so when you slam into a deeper pothole or a sharp curb cut, you do get that kick in the heels. It's not magic carpet stuff, but compared with rigid commuters, it's a clear step up. Add the wide, stable deck and generous bars, and the KQi 300 feels confident weaving through traffic, even when the surface gets sketchy.
The GMAX Ultra, by contrast, relies purely on its air-filled tyres and weight for comfort. On decent bike paths and newer city tarmac, it's actually fine - the larger tyres and heavy deck give it a bit of a "low-slung cruiser" feel. But once you start stacking broken surfaces, your knees become very aware that there are no springs anywhere on the frame. After a few kilometres of old cobbles, you'll be mentally pricing front suspension kits.
Handling-wise, both are stable rather than playful. The GMAX's long wheelbase and deck-mounted battery make it track straight and calm at commuting speeds. One-handed signalling doesn't induce panic, and it resists twitchiness nicely. The NIU feels a touch more agile and communicative at the bars, helped by its geometry and excellent tyres; you can lean it into bends with more confidence, especially in the wet.
Comfort verdict: if your roads are anything less than "pretty good", the NIU wins comfortably. On smooth paths, the GMAX Ultra is acceptable, but it never quite forgets that it skipped suspension to afford that big battery.
Performance
Neither of these is trying to rip your arms off, and frankly that's a good thing in this class. They sit in the "brisk enough for city flow" category.
The NIU's punch comes from its higher-voltage setup and more muscular motor tune. Off the line, especially in the sportiest mode, it has that little shove that can surprise you the first few times. The twist throttle contributes to that sensation: roll your wrist a bit too eagerly and it responds immediately. On flat ground it gets up to its top-end cruise with confidence and, importantly, keeps decent push even as the battery starts sliding down the gauge.
On hills, the NIU is notably stronger. Steeper ramps and longer climbs that have lesser scooters crawling in the bike lane are handled with more dignity here. Heavier riders in particular will appreciate that it doesn't just die halfway up a nasty bridge approach.
The GOTRAX GMAX Ultra is more modestly powered and you can feel it. Acceleration is smoother, more linear, and definitely less exciting - which, to be fair, many commuters will happily accept in exchange for predictability. It gets to its capped top speed at a sensible pace and then just sits there. On standard urban inclines it copes, but once the gradient really spikes, you feel it losing enthusiasm, particularly if you're a heavier rider or already chewed through half the battery.
In terms of "how fast does it feel?", both top out in the same general zone, so wind-in-helmet is comparable. The NIU just feels more willing - like it still has something in reserve - while the GMAX Ultra feels like it's working harder to do the same job.
Braking is another story. The KQi 300's dual mechanical discs plus strong regen give you reassuring, two-finger stops with a good safety margin. You can lean on the front confidently without the fork pogoing or the tyre skipping around. The GMAX Ultra's rear disc plus front electronic brake combo is perfectly adequate for its performance level, but doesn't inspire quite the same "I can stop on a dime" feeling, especially on wet roads where you'll be more cautious with rear-biased braking.
Battery & Range
If the NIU wins the power contest, the GOTRAX very clearly wins the endurance round.
The GMAX Ultra's LG pack is the headline for a reason. In normal mixed riding, you're looking at commutes long enough that you start forgetting when you last plugged it in. Several days of there-and-back office runs, a detour to the shops, a lazy weekend ride - it shrugs it off and still shows a respectable battery bar. Even if you ride a bit impatiently, it still outlasts most scooters in this price band by a comfortable margin.
The NIU's battery options are decent, but less spectacular. The larger pack version will cover an average urban round trip without angst, but you'll be more aware of your throttle habits and hills. Push it in sport mode with a heavier rider and regular climbs, and you're into "plan your charging" territory rather than "charge whenever you remember". It's fine for genuine commuting, just not remarkable.
Efficiency-wise, the GOTRAX makes better use of every watt-hour. Its milder motor and simpler chassis just waste less on exuberance and suspension. The NIU trades some of that frugality for torque and comfort.
Charging times are in the same broad overnight ballpark, with the GMAX Ultra taking a bit longer thanks to the bigger pack. Given how much further it goes between charges, that feels like an acceptable trade. With the NIU, topping up mid-week is more common if you ride daily in the sprightlier modes.
If you're the sort of rider who hates even thinking about charging, the GMAX Ultra is the clear choice. If you're fine plugging in most days and prefer a livelier motor and suspension for your trouble, the NIU's compromise is reasonable - just not particularly generous.
Portability & Practicality
Let's be blunt: neither of these is "throw it over your shoulder and jog up the stairs" material. Both sit in that awkward "liftable, but only just" class.
The GMAX Ultra feels like exactly what it is: a big battery bolted into a scooter. Carrying it up even a single long staircase is a small workout, and you won't want to be doing that several times a day. Once folded, though, the geometry is sensible - stem hooks to the rear, the package is relatively tidy, and it will slot under a desk or into a car boot without too much grumbling, as long as you're not also carrying half of IKEA.
The NIU is no feather either and makes things slightly worse by keeping its handlebars full-width even when folded. That means it takes up more floor space in hallways and on public transport, and is more awkward to wrestle through narrow doors or up twisting staircases. The folding mechanism itself is excellent - solid, quick, and mercifully free of play - but portability was clearly not the top priority.
In everyday use, both work best in "door-to-door" scenarios: roll it out of the flat, into the lift, onto the street; reverse the procedure at work. If your trip involves busy trains, buses or multiple flights of stairs, you'll start questioning your life choices quite quickly.
Practical extras slightly favour the GOTRAX. The integrated cable lock in the stem is genuinely handy for quick café or shop stops; no, it won't defeat serious thieves, but it does stop opportunistic grab-and-go thefts and saves you digging for a lock every time you want a coffee. The NIU counters with app-based electronic locking and a stronger water-resistance rating, but those help more with peace of mind than basic daily convenience.
Safety
Both scooters take safety reasonably seriously, though again, with different emphases.
On the NIU, stability is excellent. Wide bars, a long, broad deck and that front suspension keeping the wheel glued to the ground all work together. Hit a mid-corner bump at speed and it shrugs it off with far less drama than a rigid fork scooter would. Dual mechanical discs plus adjustable regenerative braking give you very controlled deceleration, and you can tailor how aggressively it slows the moment you roll off the throttle.
The lighting package is one of NIU's trump cards. The signature halo headlight isn't just for show; the beam pattern and brightness are genuinely useful for night riding at commuter speeds, and you're far more visible to others than on the typical "token LED" most commuter scooters ship with. Add integrated bar-end indicators and a bright rear light, and the NIU does a better job of making you look like a legitimate road user rather than a stealthy ninja on wheels.
The GOTRAX counters with capable, if less dramatic, safety features. The headlight is a good step up from budget fare - usable for city night riding, though not quite in the NIU's league. The rear light reacting to braking is a nice touch, and the reflectors sprinkled around the chassis help at junctions.
Braking performance is adequate for its speed range: the rear disc plus front electronic brake slow the scooter steadily rather than aggressively. On wet or dusty surfaces, having most of the braking at the rear helps avoid front washouts, but you also don't get that sharp, short-distance bite the NIU can muster.
Tyre grip on both is good thanks to sensible, air-filled rubber. The NIU's wider, tubeless setup feels a bit more planted when you lean it over or panic-brake on less-than-perfect tarmac. The GMAX Ultra's hardware is competent, but the lack of suspension means the wheel can skip a little more on sudden sharp bumps under braking.
Overall, if night riding, mixed-weather use and busy traffic are part of your life, the NIU has the safer, more confidence-inspiring package. The GOTRAX is safe enough for typical urban use, just not especially impressive.

Price & Value
We're talking roughly mid-seven hundreds in euros for both, give or take local deals and sales. So the question isn't "which is cheaper", it's "what do you actually get for that chunk of money?".
The NIU sells you on comfort features and a feeling of premium solidity. You're buying a well-known brand with a strong design language, front suspension, very good lights, serious brakes and a motor system that doesn't give up easily on hills or under heavier riders. For daily urban use where roads are imperfect and traffic is dense, that value proposition is pretty sensible - even if the scooter itself doesn't feel wildly exceptional in any one metric.
The GMAX Ultra puts almost all its value eggs in the battery basket. Brand-name cells, big capacity, and decent build quality at a sticker price that undercuts many "premium" range rivals. If you measure value in euros per kilometre ridden, it comes out looking very strong. Yes, comfort is basic and the overall feel is more practical than aspirational, but as a cost-per-commute machine, it's hard to argue with.
If your primary concern is "how many reliable kilometres can I squeeze out of this over a few years", the GOTRAX has the edge. If you care more about day-to-day ride quality, refinement and stopping power than absolute efficiency, the NIU's hardware starts to make more sense.
Service & Parts Availability
NIU has something many mid-tier scooter brands lack: a real presence. Between dealers, service partners and a global footprint from their moped business, it's generally easier to find someone who at least knows what a NIU is, and can source a brake disc or controller without going on a detective quest. Parts availability in Europe is fairly solid, though you might still wait a bit for less common components.
GOTRAX is better known in North America, but they've improved their parts situation in general. Spares are sold directly online, which is fantastic for DIY-ers. The downside in Europe is a bit more uncertainty around local service: you're more likely to either do your own work or rely on independent shops willing to work on it. Feedback on GOTRAX support is mixed: some riders get quick resolutions, others report slow communication.
Neither brand is perfect in this department, but NIU has the more established "serious vehicle" ecosystem, whereas GOTRAX leans on being relatively simple to keep running and having parts available, if not always locally stocked.

Final Verdict - Which Should You Choose?
Both of these scooters live in the "competent but not life-changing" category - and that's not an insult. For commuting, boringly dependable is often better than exciting but fragile.
If I had to pick one for the average urban rider with decent but not perfect roads, a medium-length commute and a desire to spend more time riding than charging, I'd lean towards the GOTRAX GMAX Ultra. Its range headroom simply makes everyday life easier: fewer plug-ins, less mental arithmetic about whether you'll make it home, and a generally calm demeanour at speed. It's not thrilling, but it gets the job done with minimal drama and very good cost-per-kilometre.
The NIU KQi 300, though, is the better choice if your environment is rougher, wetter, hillier or just generally more chaotic. The front suspension, stronger brakes, superior lights and extra motor muscle make it feel more grown-up in traffic and less punishing on bad surfaces. You pay a bit in weight, efficiency and practicality, but you gain comfort and control where the GMAX Ultra starts to feel out of its depth.
So: if your priority is range and simplicity, the GMAX Ultra edges it. If you value comfort, hills and safety hardware more than raw distance, the KQi 300 remains a sensible - if slightly heavy-handed - companion.
