GOTRAX G4 vs NIU KQi3 Sport: Which Should You Buy? (2026)
The GOTRAX G4 and the NIU KQi3 Sport land close enough on price and class to be genuine cross-shops — $449 against $419, and both sit in the commuter class. Every figure below is the manufacturer's published claim or a value we compute from it; where a maker leaves a spec unpublished we show a dash rather than guess, and a blank is never counted against a scooter.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 G4 claims 25 miles but realistically returns about 14–18; the KQi3 Sport's 24.9-mile claim works out to roughly 14–17. 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 G4 — 8 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 GOTRAX G4 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 NIU KQi3 Sport 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 G4 holds 374 Wh and the KQi3 Sport 365 Wh. The GOTRAX G4's 2% 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 G4's 25-mile figure realistically works out to about 14–18 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. 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: 37 lb against 40.6 lb, a 3.6 lb difference. If you carry the scooter up stairs or onto a train, the lighter GOTRAX G4 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 Sport 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 ($449 and $419), so cost is not the deciding factor here — the money is the same whichever you pick. Within their category the GOTRAX G4 scores higher (40/100 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.

Where the G4 wins
The GOTRAX G4 carries more nominal power (500 W vs 300 W), is faster (20 mph vs 17.4 mph), is lighter to carry (37 lb vs 40.6 lb), carries the bigger battery (374 Wh vs 365 Wh), and claims more range (25 mi vs 24.9 mi). That is a meaningful spread of advantages, not a single headline number.
Where the KQi3 Sport wins
The NIU KQi3 Sport is better sealed against water (IP54 vs none published), costs less ($419 vs $449), and takes a heavier load (265 lb vs 264 lb). Together those make it the stronger sheet in several areas.
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.
- 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.
- water resistance
- An IP rating describes water resistance, not immersion — it covers rain and splashes, never standing water or a pressure washer.
- top speed
- A top-speed figure is a ceiling reached under ideal conditions; rider weight and gradient both pull it down, so it describes headroom rather than a cruising promise.
- 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.
- 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.
- 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 G4 if you want more sustained power (500 W vs 300 W — a decisive 40% edge), or you want the faster ride (20 mph vs 17.4 mph — a modest 13% edge). Buy the NIU KQi3 Sport if you ride in the wet (IP54 vs none published), or you want to spend less ($419 vs $449). Whichever you pick, 1 specification are identical across both — drive — so those rows cannot decide it. Within their category our score puts the GOTRAX G4 at 40/100 against 33/100.
Bottom line: the GOTRAX G4 is the safer default here — it carries more nominal power (500 W vs 300 W). The NIU KQi3 Sport earns its place if better sealed against water (IP54 vs none published) 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 G4 or the NIU KQi3 Sport better overall?
Within their category, the GOTRAX G4 scores 40/100 and the NIU KQi3 Sport scores 33/100. 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 G4 works out to about 14–18 miles and the KQi3 Sport to about 14–17. The one with the larger battery (374 Wh vs 365 Wh) holds its distance better under load.
Which is cheaper to buy?
The NIU KQi3 Sport is the cheaper of the two at $419 against $449. 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 G4 is lighter at 37 lb versus 40.6 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 Sport publishes a water-resistance rating (IP54); the other does not, which is a reason for caution if you ride in the wet.
