A green ✓ marks the better figure on that row. “—” means the manufacturer does not publish it; a blank is never counted as a loss. Scores compare each model within its own category.

What the makers don't publish

NIU publishes every specification we track for the NIU KQi 300X. Segway (Ninebot) does not publish suspension and brake hardware for the Segway Max G2 — 2 of the 15 specifications we track. We show a dash for each of those rather than estimate, and a missing figure is never counted against a scooter in our scoring — the component is dropped and the remaining weights renormalise. Those rows cannot be compared head to head, so treat this as a comparison of what is published rather than a complete picture. If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a reasonable prompt to look harder.

Motor & speed

On top speed the two are effectively level — 23.6 mph plays 22 mph — so speed alone will not decide this, and you should weigh the other rows more heavily. Motor output is broadly matched, so neither will feel dramatically stronger pulling away from a stop. Read any top-speed figure as a maximum reached under ideal conditions; rider weight and gradient both pull it down in the real world, so treat these numbers as a ceiling rather than a cruising promise.

Battery & range

Battery capacity is the honest way to compare range, because watt-hours cannot be marketed around: the KQi 300X holds 608 Wh and the Max G2 551 Wh. The NIU KQi 300X's 10% larger pack will out-last the other on the same route whatever the two brochures claim, and it is the single number to trust most in this section. Both claims deserve the usual discount. The KQi 300X's 37.3-mile figure realistically works out to about 21–26 miles once you account for a normal rider at real speeds; the Max G2's 43 lands at roughly 24–30. Plan around the lower end of whichever band matters to you: if your daily round trip does not fit inside it with margin to spare, the range difference here is the deciding factor and you should pick the bigger battery. Recharging also differs: the Segway Max G2 is back to full in about 5 hours against 6, which matters if you top up between a morning and evening commute rather than overnight. Whichever you choose, remember that both figures assume a fresh battery; a pack loses roughly 20–30% of its capacity after a couple of years of daily cycling, so a used example of either will fall short of these numbers.

Build & ride

Weight is where the daily reality lives: 48.7 lb against 53.5 lb, a 4.8 lb difference. If you carry the scooter up stairs or onto a train, the lighter NIU KQi 300X is the one you will actually keep using — the difference between a scooter that gets ridden and one that gathers dust is often a single flight of steps. Only the NIU KQi 300X has suspension at both ends, the single upgrade that most changes how a scooter feels on cracked city pavement; the other leans on its tyres to take the edge off, which works but not as well. Each publishes a water-resistance rating (IP55 and IPX5); the higher of the two shrugs off heavier rain, though neither should be ridden through standing water or pressure-washed.

Price, score & value

The NIU KQi 300X is the cheaper of the two, $699 against $750 — a $51 gap. Whether that gap is worth closing depends entirely on whether the pricier scooter's advantages above line up with your priorities. Within their category the NIU KQi 300X scores higher (66/100 to 62/100). Remember that our scores are within-category judgements — this comparison is only meaningful because both sit in the same or an adjacent class. If value per dollar is your lens, use the cost-of-ownership calculator on this site: a slightly cheaper scooter with pneumatic tyres can cost more to run over a few years than a pricier one on solid tyres, and the sticker price alone hides that.

What's identical

These two share more than they differ on. 4 published specifications are identical across both: peak power (1000 W), max load (265 lb), tyre type (tubeless), drive (Single motor). That matters more than it first appears, because it narrows the decision to a short list: the 11 measures where they actually diverge — suspension, system voltage, charge time and others — carry the whole choice. Anything on the identical list can be set aside: it will be the same experience whichever you buy, so it should not sway you either way.

• Peak power: 1000 W
• Max load: 265 lb
• Tyre type: tubeless
• Drive: Single motor

What these numbers actually govern

Here is what each of these measures controls in general — both the ones that separate these two and the ones they share. These describe the measure, not a claim about how either scooter rides, which we have not tested.

suspension

Suspension at both ends changes how a scooter handles broken pavement more than any other single component; a single unit covers one end only, and none leaves the tyres to do the work.

system voltage

Higher-voltage systems typically hold performance better under load — hills and heavier riders — with less sag at the same power draw.

charge time

Charge time matters most if you top up between a morning and an evening commute rather than overnight.

claimed range

Every claimed range figure is measured at a light rider weight, a low constant speed and on flat ground, which is why we show a computed real-world band beside it.

max incline

A climbing grade is quoted under test conditions; a heavier rider reaches the limit sooner than the published figure suggests.

Max load (both 265 lb)identical on both

A load rating covers rider plus cargo, not the rider alone. Where both models publish the same limit, rider weight cannot separate them.

Tyre type (both tubeless)identical on both

Pneumatic and tubeless tyres absorb road imperfections that solid tyres pass into the deck; solid tyres trade that comfort for never puncturing. A shared construction means the same trade on both.

Drive (both Single motor)identical on both

A second motor adds traction and acceleration at the cost of weight and battery drain. Where both use the same arrangement, drive layout is not a separator.

Price & where to buy

Who should buy which

Buy the NIU KQi 300X if your roads are rough (dual suspension vs none), or you want the higher-voltage system (48 V vs 36 V) for less sag under load. Buy the Segway Max G2 if you top up between commutes rather than overnight (5 h vs 6 h), or your trips are longer and range decides it (43 mi vs 37.3 mi claimed — a modest 13% edge). Whichever you pick, 4 specifications are identical across both — peak power, max load, tyre type — so those rows cannot decide it. Within their category our score puts the NIU KQi 300X at 66/100 against 62/100.

Bottom line: the NIU KQi 300X is the safer default here — it has more suspension (dual vs none). The Segway Max G2 earns its place if faster (5 h vs 6 h) matters more to you. Every figure here is the manufacturer's published claim or a value we compute from it, linked back to each maker's own specification so you can check it yourself.
