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

Apollo does not publish nominal power for the Apollo Explore 2.0 — 1 of the 15 specifications we track. NIU publishes every specification we track for the NIU KQi 300X. 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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 — 25 mph plays 23.6 mph — so speed alone will not decide this, and you should weigh the other rows more heavily. The Apollo Explore 2.0 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 Explore 2.0 holds 648 Wh and the KQi 300X 608 Wh. The Apollo Explore 2.0's 7% 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 Explore 2.0's 37-mile figure realistically works out to about 20–26 miles once you account for a normal rider at real speeds; the KQi 300X's 37.3 lands at roughly 21–26. 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 300X is back to full in about 6 hours against 8, 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: 60 lb against 48.7 lb, a 11.3 lb difference. If you carry the scooter up stairs or onto a train, the lighter NIU KQi 300X 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. Both run suspension at both ends, so both should ride comfortably over broken ground — a genuine point in common rather than a tie-breaker. Each publishes a water-resistance rating (IP66 and IP55); 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 KQi 300X is the cheaper of the two, $699 against $849 — 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 300X scores higher (66/100 to 62/100). 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

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.

peak power

Peak power is a short-burst figure — it describes acceleration headroom rather than what a motor can hold on a sustained climb.

brakes

Hydraulic discs are more consistent at the lever than mechanical discs, and drums trade outright stopping power for lower maintenance — a difference that grows with speed.

charge time

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

water resistance

An IP rating describes water resistance, not immersion — it covers rain and splashes, never standing water or a pressure washer.

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.

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 dual)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.

Tyre type (both tubeless)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

Buy the Apollo Explore 2.0 if you want more peak output (1650 W vs 1000 W — a decisive 39% edge), or you ride in the wet (IP66 vs IP55). Buy the NIU KQi 300X if you want the stronger braking hardware, or you top up between commutes rather than overnight (6 h vs 8 h). Whichever you pick, 5 specifications are identical across both — voltage, max load, suspension — so those rows cannot decide it. Within their category our score puts the NIU KQi 300X at 66/100 against 62/100.

Bottom line: the NIU KQi 300X is the safer default here — it uses stronger braking hardware. The Apollo Explore 2.0 earns its place if higher (1650 W vs 1000 W) 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.
