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 300P. Segway (Ninebot) does not publish nominal power, battery capacity, system voltage, climbing grade, and brake hardware for the Segway E3 Pro — 5 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 — 20 mph plays 20 mph — so speed alone will not decide this, and you should weigh the other rows more heavily. The NIU KQi 300P carries more motor on paper, and that surplus shows up in acceleration and on climbs rather than in a higher cruising speed — the place a stronger motor actually earns its keep is the hill you take twice a day. 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

Both claims deserve the usual discount. The KQi 300P's 30-mile figure realistically works out to about 17–21 miles once you account for a normal rider at real speeds; the E3 Pro's 34 lands at roughly 19–24. 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. 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: 46.0 lb against 40.1 lb, a 5.9 lb difference. If you carry the scooter up stairs or onto a train, the lighter Segway E3 Pro 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. Both run suspension at both ends, so both should ride comfortably over broken ground — a genuine point in common rather than a tie-breaker. 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

On price the two are almost identical ($599 and $600), so cost is not the deciding factor here — the money is the same whichever you pick. Within their category the NIU KQi 300P scores higher (52/100 to 51/100). 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. 5 published specifications are identical across both: top speed (20 mph), max load (265 lb), suspension (dual), tyre type (tubeless), drive (Single motor). That matters more than it first appears, because it narrows the decision to a short list: the 6 measures where they actually diverge — weight, claimed range, peak power 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.

• Top speed: 20 mph
• Max load: 265 lb
• Suspension: dual
• 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.

weight

Weight decides the moments off the scooter: carrying it up a flight of stairs, lifting it onto transit, loading it into a car boot.

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.

peak power

Peak power is a short-burst figure — it describes acceleration headroom rather than what a motor can hold on a sustained climb.

charge time

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

tyre diameter

Larger-diameter tyres roll over road imperfections more easily and drop into potholes less abruptly than small ones.

Top speed (both 20 mph)identical on both

A top-speed figure is a ceiling reached under ideal conditions; an identical claim means neither has headroom the other lacks.

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.

Suspension (both dual)identical on both

Suspension is the component that most changes how a scooter handles broken pavement; where both models carry the same arrangement, road comfort is not a differentiator between 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 300P if you want more peak output (900 W vs 800 W — a modest 11% edge), or you top up between commutes rather than overnight (5 h vs 5.5 h). Buy the Segway E3 Pro if you carry it up stairs or onto transit (40.1 lb vs 46.0 lb — a modest 13% edge), or your trips are longer and range decides it (34 mi vs 30 mi claimed — a modest 12% edge). Whichever you pick, 5 specifications are identical across both — top speed, max load, suspension — so those rows cannot decide it. Within their category our score puts the NIU KQi 300P at 52/100 against 51/100.

Bottom line: the NIU KQi 300P is the safer default here — it peaks higher (900 W vs 800 W). The Segway E3 Pro earns its place if lighter to carry (40.1 lb vs 46.0 lb) 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.
