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

Hiboy does not publish tyre size for the Hiboy Titan — 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 If one of the unpublished figures is the one your decision turns on, ask the seller in writing before you buy: a maker that measures a specification usually states it, and silence is a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

The Hiboy Titan is the faster of the pair, 28 mph against 23.6 mph — a 4.4 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. At the Titan's speeds, braking matters more than the extra miles per hour: check the build section below, because stopping distance climbs faster than speed does. The Hiboy Titan 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 Titan holds 864 Wh and the KQi 300X 608 Wh. The Hiboy Titan's 42% 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 Titan's 46-mile figure realistically works out to about 25–32 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 7, 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: 77.1 lb against 48.7 lb, a 28.4 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 (IPX4 and IP55); the higher of the two shrugs off heavier rain, though neither should be ridden through standing water or pressure-washed. Braking favours the Hiboy Titan, whose hydraulics are stronger and more consistent at the lever than the other's setup — the specification that matters most as speed rises, and worth prioritising over almost any other feature on a fast scooter.

Price, score & value

The NIU KQi 300X is the cheaper of the two, $699 against $900 — a $201 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 60/100). 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 $201 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.

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.

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.

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.

battery capacity

Watt-hours are the single best predictor of range, because capacity is the one range input that cannot be marketed around.

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.

Max incline (both 25%)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.

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 Hiboy Titan if you want more sustained power (750 W vs 500 W — a decisive 33% edge), or you want the stronger braking hardware. Buy the NIU KQi 300X if you carry it up stairs or onto transit (48.7 lb vs 77.1 lb — a decisive 37% edge), or you want to spend less ($699 vs $900). Whichever you pick, 5 specifications are identical across both — voltage, max incline, suspension — so those rows cannot decide it. Within their category our score puts the NIU KQi 300X at 66/100 against 60/100.

Bottom line: the NIU KQi 300X is the safer default here — it is lighter to carry (48.7 lb vs 77.1 lb). The Hiboy Titan earns its place if more nominal power (750 W vs 500 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.
