Hiboy MAX Pro vs NIU KQi 300X: Which Should You Buy? (2026)
The Hiboy MAX Pro and the NIU KQi 300X land close enough on price and class to be genuine cross-shops — $657 against $699, 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 Every figure below is the manufacturer's published claim or a value we compute from it; where a maker leaves a spec unpublished we show a dash rather than guess, and a blank is never counted against a scooter.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 MAX Pro claims 46.6 miles but realistically returns about 26–33; the KQi 300X's 37.3-mile claim works out to roughly 21–26. 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.

Motor & speed
On top speed the two are effectively level — 22 mph plays 23.6 mph — so speed alone will not decide this, and you should weigh the other rows more heavily. The NIU KQi 300X 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. The Hiboy MAX Pro also claims the steeper hill-climbing grade, worth noting if your commute has a real gradient rather than a gentle rise. 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 MAX Pro holds 720 Wh and the KQi 300X 608 Wh. The Hiboy MAX Pro's 18% 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 MAX Pro's 46.6-mile figure realistically works out to about 26–33 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 8.5, 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: 51.6 lb against 48.7 lb, a 2.9 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. Tyres differ too: MAX Pro runs pneumatic and KQi 300X tubeless. Pneumatic and tubeless tyres absorb more of the road than solid ones, at the cost of the occasional puncture; solid tyres never flat but pass more buzz into your hands and feet.
Price, score & value
On price the two are almost identical ($657 and $699), so cost is not the deciding factor here — the money is the same whichever you pick. 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's identical
These two share more than they differ on. 5 published specifications are identical across both: nominal power (500 W), voltage (48 V), max load (265 lb), suspension (dual), drive (Single motor). That matters more than it first appears, because it narrows the decision to a short list: the 11 measures where they actually diverge — peak power, max incline, brakes and others — carry the whole choice. Anything on the identical list can be set aside: it will be the same experience whichever you buy, so it should not sway you either way.
- Nominal power: 500 W
- Voltage: 48 V
- Max load: 265 lb
- Suspension: dual
- Drive: Single motor
Where the MAX Pro wins
The Hiboy MAX Pro claims a steeper grade (36.4% vs 25%), claims more range (46.6 mi vs 37.3 mi), carries the bigger battery (720 Wh vs 608 Wh), costs less ($657 vs $699), and runs a larger tyre (11" vs 10.5"). That is a meaningful spread of advantages, not a single headline number.
Where the KQi 300X wins
The NIU KQi 300X peaks higher (1000 W vs 650 W), uses stronger braking hardware, recharges faster (6 h vs 8.5 h), is better sealed against water (IP55 vs IPX4), is faster (23.6 mph vs 22 mph), and is lighter to carry (48.7 lb vs 51.6 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.
- peak power
- Peak power is a short-burst figure — it describes acceleration headroom rather than what a motor can hold on a sustained climb.
- max incline
- A climbing grade is quoted under test conditions; a heavier rider reaches the limit sooner than the published figure suggests.
- 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.
- 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.
- 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 Hiboy MAX Pro if your route has a real gradient (36.4% vs 25% claimed grade), or your trips are longer and range decides it (46.6 mi vs 37.3 mi claimed — a clear 20% edge). Buy the NIU KQi 300X if you want more peak output (1000 W vs 650 W — a decisive 35% edge), or you want the stronger braking hardware. Whichever you pick, 5 specifications are identical across both — nominal power, voltage, max load — 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 peaks higher (1000 W vs 650 W). The Hiboy MAX Pro earns its place if a steeper grade (36.4% vs 25%) 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.
