GOTRAX G4 vs NIU KQi 300P: Which Should You Buy? (2026)

The GOTRAX G4 and the NIU KQi 300P land close enough on price and class to be genuine cross-shops — $449 against $599, 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 Every figure below is the manufacturer's published claim or a value we compute from it; where a maker leaves a spec unpublished we show a dash rather than guess, and a blank is never counted against a scooter.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 KQi 300P's 30-mile claim works out to roughly 17–21. 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 publishes every specification we track for the NIU KQi 300P. 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 20 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 G4 holds 374 Wh and the KQi 300P 487 Wh. The NIU KQi 300P's 30% 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 KQi 300P's 30 lands at roughly 17–21. 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 46.0 lb, a 9.0 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 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. Only the NIU KQi 300P publishes a water rating (IP55). 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

The GOTRAX G4 is the cheaper of the two, $449 against $599 — a $150 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 40/100). 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 $150 buys

The NIU KQi 300P costs $150 more. That buys:

  • suspension: dual vs none
  • system voltage: 48 V vs 36 V
  • battery capacity: 487 Wh vs 374 Wh
  • water resistance: IP55 vs none published
  • claimed range: 30 mi vs 25 mi
  • max load: 265 lb vs 264 lb
It also costs you:
  • weight: 46.0 lb vs 37 lb
  • nominal power: 500 W vs 450 W

It does not buy:

  • top speed (both 20 mph)
  • drive (both Single motor)

Where the G4 wins

The GOTRAX G4 costs less ($449 vs $599), is lighter to carry (37 lb vs 46.0 lb), and carries more nominal power (500 W vs 450 W). That is a meaningful spread of advantages, not a single headline number.

Where the KQi 300P wins

The NIU KQi 300P has more suspension (dual vs none), runs a higher-voltage system (48 V vs 36 V), carries the bigger battery (487 Wh vs 374 Wh), is better sealed against water (IP55 vs none published), claims more range (30 mi vs 25 mi), 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.

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.
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.
system voltage
Higher-voltage systems typically hold performance better under load — hills and heavier riders — with less sag at the same power draw.
battery capacity
Watt-hours are the single best predictor of range, because capacity is the one range input that cannot be marketed around.
water resistance
An IP rating describes water resistance, not immersion — it covers rain and splashes, never standing water or a pressure washer.
Top speed (both 20 mph)identical on both
A top-speed figure is a ceiling reached under ideal conditions; an identical claim means neither has headroom the other lacks.
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 to spend less ($449 vs $599), or you carry it up stairs or onto transit (37 lb vs 46.0 lb — a clear 20% edge). Buy the NIU KQi 300P if your roads are rough (dual suspension vs none), or you want the higher-voltage system (48 V vs 36 V) for less sag under load. Whichever you pick, 2 specifications are identical across both — top speed, drive — so those rows cannot decide it. Within their category our score puts the NIU KQi 300P at 52/100 against 40/100.

Bottom line: the NIU KQi 300P is the safer default here — it has more suspension (dual vs none). The GOTRAX G4 earns its place if less ($449 vs $599) 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 KQi 300P better overall?

Within their category, the NIU KQi 300P scores 52/100 and the GOTRAX G4 scores 40/100. 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 KQi 300P to about 17–21. The one with the larger battery (374 Wh vs 487 Wh) holds its distance better under load.

Which is cheaper to buy?

The GOTRAX G4 is the cheaper of the two at $449 against $599. 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 46.0 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 KQi 300P publishes a water-resistance rating (IP55); the other does not, which is a reason for caution if you ride in the wet.
