24.3 mi estimated · 37.3 mi claimed · 26.8 mi tested

The claim is 1.5× the estimate. How this is worked out.

Owners describe the 300X, accurately, as a KQi3 Max with the things the Max was missing: a hydraulic fork, handlebar turn signals, 10.5-inch tires, a twist throttle and a kilowatt of peak power. It keeps the 608 Wh pack, and the measured range holds up at 26.8 miles against 37.3 claimed. The fork is the part owners keep returning to — more than one has compared it favourably with the front suspension on a full-size e-bike, which is not something you often read about a scooter fork. GPS-verified top speed matches the display at around 24 mph, and the climb rate is slightly better than the Max's. At 48.7 pounds it is at the upper end of what one person moves comfortably, and the suspension is still front-only, so the rear wheel relies on tire volume. This is the version of NIU's commuter platform to buy if you are not carrying it upstairs.

35-55 lb — you can lift it into a boot or over a kerb, not carry it far. Estimated range is our own calculation from the battery capacity; the claim is the manufacturer’s.

Features

  • Hydraulic front fork
  • 1,000 W peak motor
  • 608 Wh pack
  • 10.5-inch self-healing tubeless tires
  • Handlebar-mounted turn signals
  • Twist throttle
  • Dual mechanical discs with regen
  • IP55 rating

In its favour

  • Owners rate the hydraulic fork as comparable to a full-size e-bike's front suspension
  • Tested 26.8 miles, and GPS-verified top speed matches the display
  • 1,000 W peak and a 36% rated slope give it real climbing pace
  • Handlebar turn signals rather than the stem-mounted kind
  • Self-healing 10.5-inch tires are the widest in NIU's range

Against it

  • 48.7 lb — heaviest of NIU's folding commuters
  • Front suspension only, despite the price
  • Six-hour charge, slower than the 300P's five
  • Costs the same as the KQi3 Max, which is lighter and goes further per watt-hour

The lists above combine the specification sheet with what owners of this model report.

What owners say

Summarised from owner discussions and long-term owner write-ups.

Owners describe the 300X accurately as a KQi3 Max with the things the Max was missing, and the list is specific: a hydraulic fork, handlebar turn signals, 10.5-inch tires, a twist throttle and a kilowatt of peak power. The fork is what people write about. More than one owner has compared it directly with the front suspension on a full-size e-bike and found it comparable, which is not something you usually read about a scooter.

The measured numbers hold up too — 26.8 tested miles, and a GPS-verified top speed that matches the display. What you pay is weight: at 48.7 pounds it is the heaviest folding commuter NIU makes, and there is nothing on it designed to be carried by. Buy it if the scooter lives at ground level.

What owners like

  • Owners rate the hydraulic fork as matching or exceeding the front suspension on a full-size e-bike, which is unusual praise for a scooter fork
  • GPS-verified top speed matches what the dashboard shows — around 24 mph, held as long as there is charge
  • Owners describe it as sturdy in the same tank-like way as the KQi3 range, with the components feeling built to last
  • Handlebar-mounted turn signals rather than the stem-mounted kind, which are far easier to see
  • A twist throttle, a louder mechanical bell and a kilowatt of peak motor over the KQi3 Max it is based on
  • Tested 26.8 miles, which is a genuine commute rather than a marketing number

Common complaints

  • 48.7 lb, the heaviest of NIU's folding commuters, with no comfortable way to carry it
  • Front suspension only — the rear wheel still relies on tire volume at 23.7 mph
  • Six hours to charge, slower than the 300P's five
  • It costs the same as the KQi3 Max, which is lighter and gets further per watt-hour

Questions people ask

Is the 300X just a KQi3 Max with a fork?
Broadly, yes — same 608 Wh battery, same rider limit, similar geometry — plus handlebar turn signals, 10.5-inch tires, a twist throttle and 1,000 W peak instead of 900. Owners who have had both describe the suspension as the change that matters and the rest as welcome extras.
Does it actually do 24 mph?
Yes. Owners have verified the dashboard reading against a GPS app and found it accurate, and the speed holds as long as the battery has charge in it. That is worth noting because plenty of scooters in this class read optimistically.
How is it in the rain?
IP55 with self-healing tires, which is a step above the IP54 on the KQi3 range and adequate for a wet commute. Avoid standing water and dry the charging port before plugging in. It is not an IPX6 scooter and should not be treated as one.
Can I carry it up stairs?
Occasionally, awkwardly. At 48.7 pounds with no dedicated carry point it is the heaviest thing in NIU's folding range. If stairs are part of every commute, the KQi Air at 26.4 pounds is the model designed for that problem.
