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 does not publish system voltage for the NIU KQi3 Sport — 1 of the 15 specifications we track. 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. Because both sheets have holes, several rows of the table above cannot be compared at all, 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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

The Segway E3 Pro is the faster of the pair, 20 mph against 17.4 mph — a 2.6 mph gap that shows on open stretches but rarely in traffic, where junctions and shared paths set the pace regardless of what the scooter can do. The Segway E3 Pro 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 KQi3 Sport's 24.9-mile figure realistically works out to about 14–17 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: 40.6 lb against 40.1 lb, a 0.5 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. Only the Segway E3 Pro 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 (IP54 and IPX5); the higher of the two shrugs off heavier rain, though neither should be ridden through standing water or pressure-washed. Tyres differ too: KQi3 Sport runs pneumatic and E3 Pro tubeless. Pneumatic and tubeless tyres absorb more of the road than solid ones, at the cost of the occasional puncture; solid tyres never flat but pass more buzz into your hands and feet.

Price, score & value

The NIU KQi3 Sport is the cheaper of the two, $419 against $600 — a $181 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 Segway E3 Pro scores higher (51/100 to 33/100). 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 the extra $181 buys

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.

price

Price is the one figure that is not a specification — it moves with stock and promotions, so treat any gap as current rather than permanent.

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.

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.

water resistance

An IP rating describes water resistance, not immersion — it covers rain and splashes, never standing water or a pressure washer.

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.

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 KQi3 Sport if you want to spend less ($419 vs $600), or you top up between commutes rather than overnight (5 h vs 5.5 h). Buy the Segway E3 Pro if your roads are rough (dual suspension vs none), or your trips are longer and range decides it (34 mi vs 24.9 mi claimed — a clear 27% edge). Whichever you pick, 2 specifications are identical across both — max load, drive — so those rows cannot decide it. Within their category our score puts the Segway E3 Pro at 51/100 against 33/100.

Bottom line: the Segway E3 Pro is the safer default here — it has more suspension (dual vs none). The NIU KQi3 Sport earns its place if less ($419 vs $600) 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.
