NIU electric scooters
NIU's engineering priority is visible in the measured data: they build the most efficient scooters in our registry, and they charge for it.

Where NIU sits
NIU sits at the premium end of the commuter market and competes on efficiency rather than on headline numbers. Across the three models we have independent data for, none is the fastest or the most powerful in its class — and two of the three lead their category on miles of measured range per pound of scooter.
The KQi naming runs roughly by capability: the 100F is the compact entry, the 300X the full-size all-rounder, and the Air the ultralight flagship.
The line-up we have data for
These are the NIU models with independently sourced figures in our registry. It is not the brand’s full catalog — it is the part of it somebody has published numbers for, which is the only part we will write about.

Measured figures come from a named third-party test; Claim figures come from the manufacturer. Sources are listed under each model below. Empty specifications read “Not published” rather than being estimated.
NIU models with sourced data
Each model below links to its full write-up where one exists. Prices are never live on this site — where we quote one it is what a dated source listed when we read it.
NIU KQi 300X
The balanced answer: 26.8 measured miles, 23.6 mph and dual disc brakes at a weight you can still fold into a trunk.
NIU KQi Air
The lightest genuinely usable commuter we found data for — 26.4 lb, and it still measured 24.2 miles.
NIU KQi 100F
A genuinely cheap compact that measured 11.4 miles — enough for a short campus or last-mile hop and nothing more.
What the numbers show
Efficiency is the brand
Dividing measured range by measured weight gives NIU the two best figures in our registry after VMAX: the KQi Air at 0.92 miles per pound and the KQi 300X at 0.55 (eRideHero, Sep 2026). The KQi Air achieving 24.2 measured miles at 26.4 lb is the single most unusual data point we have — comparable scooters at that weight typically carry half the battery.
Modest motors, consistently
350 W, 500 W and 300 W across the three models. None clears the 1000 W threshold cited for grades above 10% (Hiboy, Sep 2026), and the KQi Air’s 350 W sits below even the 500 W figure for 5-10%. NIU builds scooters for flat and gently rolling routes; on a hilly commute the hills round-up has better options.
265 lb, every time
All three models are rated at the category default. NIU does not currently serve the heavier rider in the data we have — the heavy-rider round-up is the right page above about 240 lb.
Patchy specification publishing
The KQi Air publishes IP55 but no brake type; the KQi 300X publishes dual disc brakes but no IP rating; the KQi 100F publishes neither. That inconsistency is worth knowing when comparing models within the range.
Who should shop NIU
Buy NIU if weight matters to you — if you carry the scooter, take it on transport, or lift it into a car regularly. The KQi Air is genuinely unmatched at that, and the KQi 300X is our default recommendation across the whole site.
Look elsewhere if your route has sustained climbs, you weigh over about 240 lb, or you need a published IP rating at the same time as published brakes. Segway’s Max G3 publishes both.
What we do not know
Frequently asked questions
▸Which NIU scooter should I buy?
The KQi 300X for most people — 26.8 measured miles, dual disc brakes and 23.6 mph. The KQi Air if you carry the scooter, which is the one thing nothing else does as well.
▸Are NIU scooters good on hills?
Not especially. The three models we have data for run 300-500 W, which covers gentle gradients but sits at or below the threshold generally cited for 5-10% grades.
▸Are NIU scooters worth the premium?
If weight matters, yes — the KQi Air’s 0.92 measured miles per pound is more than double the category norm. If it does not, cheaper scooters deliver similar range for similar weight.
