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 Pro — 1 of the 15 specifications we track. NIU does not publish system voltage for the NIU KQi3 Sport — 1 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 NIU KQi3 Pro is the faster of the pair, 19.9 mph against 17.4 mph — a 2.5 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 NIU KQi3 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

Battery capacity is the honest way to compare range, because watt-hours cannot be marketed around: the KQi3 Pro holds 486 Wh and the KQi3 Sport 365 Wh. The NIU KQi3 Pro's 33% 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 KQi3 Pro's 31-mile figure realistically works out to about 17–22 miles once you account for a normal rider at real speeds; the KQi3 Sport's 24.9 lands at roughly 14–17. 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 NIU KQi3 Sport 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: 44.8 lb against 40.6 lb, a 4.1 lb difference. If you carry the scooter up stairs or onto a train, the lighter NIU KQi3 Sport 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. Each publishes a water-resistance rating (IP54 and IP54); 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 KQi3 Pro is the cheaper of the two, $330 against $419 — a $89 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 KQi3 Pro scores higher (44/100 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 $89 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.

max incline

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

battery capacity

Watt-hours are the single best predictor of range, because capacity is the one range input that cannot be marketed around.

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.

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.

charge time

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

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 none)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.

Water resistance (both IP54)identical on both

An IP rating describes water resistance, not immersion: it covers rain and splashes, never standing water or a pressure washer. A shared rating means neither is the safer choice in the wet.

Tyre type (both pneumatic)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

Step up to the NIU KQi3 Sport if you top up between commutes rather than overnight (5 h vs 6 h) — that is what the $89 buys. Save the $89 and take the NIU KQi3 Pro if your route has a real gradient (20% vs 15% claimed grade), and that matters more to you than the rows that change. The step changes 2 specifications and leaves 6 identical — max load (both 265 lb), suspension (both none), water resistance (both IP54) carry over unchanged, so the money is buying charge time rather than a different scooter.

Bottom line: the $89 step from the NIU KQi3 Pro to the NIU KQi3 Sport buys charge time, weight, and costs you max incline and battery capacity and claimed range and nominal power and peak power and top speed. It changes nothing about max load (both 265 lb), suspension (both none), water resistance (both IP54), tyre type (both pneumatic). Every figure here is the manufacturer's published claim or a value we compute from it.
