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. NIU does not publish system voltage for the NIU KQi3 Pro — 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. 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 19.9 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

Battery capacity is the honest way to compare range, because watt-hours cannot be marketed around: the KQi 300P holds 487 Wh and the KQi3 Pro 486 Wh. The NIU KQi 300P's 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 300P's 30-mile figure realistically works out to about 17–21 miles once you account for a normal rider at real speeds; the KQi3 Pro's 31 lands at roughly 17–22. 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 KQi 300P 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: 46.0 lb against 44.8 lb, a 1.2 lb difference. If you carry the scooter up stairs or onto a train, the lighter NIU KQi3 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 NIU KQi 300P 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 IP54); the higher of the two shrugs off heavier rain, though neither should be ridden through standing water or pressure-washed. Tyres differ too: KQi 300P runs tubeless and KQi3 Pro pneumatic. 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 Pro is the cheaper of the two, $330 against $599 — a $269 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 300P scores higher (52/100 to 44/100). 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 $269 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.

nominal power

Nominal power describes sustained output: it shows up in acceleration and in holding speed on a long climb rather than in a higher top speed.

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.

Max incline (both 20%)identical on both

A climbing grade is quoted under test conditions and a heavier rider reaches the limit sooner than the figure suggests; an identical claim means neither is specified to climb better.

Brakes (both Dual disc front & rear + regenerative)identical on both

Braking hardware sets stopping consistency and maintenance burden — identical hardware means identical expectations at the lever, so stopping is not a reason to choose one over the other.

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 KQi 300P if your roads are rough (dual suspension vs none) — that is what the $269 buys. Save the $269 and take the NIU KQi3 Pro if your trips are longer and range decides it (31 mi vs 30 mi claimed — a marginal 3% edge), and that matters more to you than the rows that change. The step changes 8 specifications and leaves 4 identical — max load (both 265 lb), max incline (both 20%), brakes (both Dual disc front & rear + regenerative) carry over unchanged, so the money is buying suspension rather than a different scooter.

Bottom line: the $269 step from the NIU KQi3 Pro to the NIU KQi 300P buys suspension, nominal power, peak power, and costs you claimed range and weight. It changes nothing about max load (both 265 lb), max incline (both 20%), brakes (both Dual disc front & rear + regenerative), drive (both Single motor). Every figure here is the manufacturer's published claim or a value we compute from it.
