GOTRAX Fusion vs NIU KQi3 Pro: Which Should You Buy? (2026)
The GOTRAX Fusion and the NIU KQi3 Pro land close enough on price and class to be genuine cross-shops — $349 against $330, sitting in adjacent tiers (budget and commuter). Every figure below is the manufacturer's published claim or a value we compute from it; where a maker leaves a spec unpublished we show a dash rather than guess, and a blank is never counted against a scooter. One habit to carry into any range comparison is to halve the claim. The Fusion claims 14 miles but realistically returns about 8–10; the KQi3 Pro's 31-mile claim works out to roughly 17–22. The sections that follow work through where each one leads, and the verdict above already names the pick for most buyers — the detail below is there to overturn it if your priorities differ.

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
GOTRAX does not publish peak power, charge time, climbing grade, tyre size, tyre type, suspension, brake hardware, and water rating for the GOTRAX Fusion — 8 of the 15 specifications we track. 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. 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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
On top speed the two are effectively level — 18 mph plays 19.9 mph — so speed alone will not decide this, and you should weigh the other rows more heavily. 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 Fusion holds 209 Wh and the KQi3 Pro 486 Wh. The NIU KQi3 Pro's 133% 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 Fusion's 14-mile figure realistically works out to about 8–10 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. 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: 30 lb against 44.8 lb, a 14.8 lb difference. If you carry the scooter up stairs or onto a train, the lighter GOTRAX Fusion 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 KQi3 Pro publishes a water rating (IP54). The other maker's silence is not proof of a bad seal, but a manufacturer that tests for water ingress usually states the result — so treat the gap as a reason for caution in the wet.
Price, score & value
On price the two are almost identical ($349 and $330), so cost is not the deciding factor here — the money is the same whichever you pick. Within their category the NIU KQi3 Pro scores higher (44/100 to 36/100). 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.

Where the Fusion wins
The GOTRAX Fusion is lighter to carry (30 lb vs 44.8 lb). Weigh those against what it gives up below.
Where the KQi3 Pro wins
The NIU KQi3 Pro carries the bigger battery (486 Wh vs 209 Wh), claims more range (31 mi vs 14 mi), is better sealed against water (IP54 vs none published), takes a heavier load (265 lb vs 220 lb), carries more nominal power (350 W vs 300 W), is faster (19.9 mph vs 18 mph), and costs less ($330 vs $349). Together those make it the stronger sheet in several areas.
The GOTRAX Fusion leads on weight alone; the NIU KQi3 Pro leads on 7 separate measures.
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.
- battery capacity
- Watt-hours are the single best predictor of range, because capacity is the one range input that cannot be marketed around.
- 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.
- 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.
- water resistance
- An IP rating describes water resistance, not immersion — it covers rain and splashes, never standing water or a pressure washer.
- max load
- A load rating covers rider plus cargo, not the rider alone — a backpack and a week's shopping come out of the same allowance.
- 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.

Who should buy which
Buy the GOTRAX Fusion if you carry it up stairs or onto transit (30 lb vs 44.8 lb — a decisive 33% edge). Buy the NIU KQi3 Pro if you want the bigger battery (486 Wh vs 209 Wh — a decisive 57% edge), or your trips are longer and range decides it (31 mi vs 14 mi claimed — a decisive 55% edge). Whichever you pick, 1 specification are identical across both — drive — so those rows cannot decide it. Within their category our score puts the NIU KQi3 Pro at 44/100 against 36/100.
Bottom line: the NIU KQi3 Pro is the safer default here — it carries the bigger battery (486 Wh vs 209 Wh). The GOTRAX Fusion earns its place if lighter to carry (30 lb vs 44.8 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.
Frequently asked questions
Is the GOTRAX Fusion or the NIU KQi3 Pro better overall?
Within their category, the NIU KQi3 Pro scores 44/100 and the GOTRAX Fusion scores 36/100. Our scores compare models within their own category, and the two are close enough here that your priorities — carry weight, range, price — should decide it rather than the raw number.
Which one has better real-world range?
Estimated at 55–70% of the claim, the Fusion works out to about 8–10 miles and the KQi3 Pro to about 17–22. The one with the larger battery (209 Wh vs 486 Wh) holds its distance better under load.
Which is cheaper to buy?
The NIU KQi3 Pro is the cheaper of the two at $330 against $349. Prices are tracked snapshots and can change — check the current figure on each model's page before buying.
Which is easier to carry and store?
The GOTRAX Fusion is lighter at 30 lb versus 44.8 lb, so it is the better pick if you carry a scooter up stairs or onto transit. Both fold for storage; weight is the deciding factor here, not folded size.
Can I ride either one in the rain?
Only the NIU KQi3 Pro publishes a water-resistance rating (IP54); the other does not, which is a reason for caution if you ride in the wet.
