The Xiaomi Electric Scooter 4 Ultra is the top model in Xiaomi’s fourth-generation scooter line, with a 500W motor, dual suspension and the largest battery Xiaomi has put in a commuter scooter. Its headline range claim is the number most buyers ask about, so this guide reads that claim against everything else Xiaomi publishes about the scooter.
How this was produced: Electric Ride Reviews does not buy, ride or test the products it covers. Every figure below is Xiaomi’s published specification and is attributed as such.

Two things in that list matter for US buyers. The 25 km/h cap is the international version’s limit, so the 4 Ultra is not a fast scooter by US standards. And Xiaomi does not sell this model through an official US channel; units sold here are imports, which affects warranty and service.
Reading the 43-Mile Range Claim
A manufacturer range figure is the best case: a light rider, flat ground, a moderate steady speed and mild weather. Every one of those conditions moves the real number, and they compound.
Rider Weight
The motor and battery move the rider as well as the scooter, so a heavier rider uses more energy per mile. Xiaomi rates the 4 Ultra for riders up to 120 kg, but riders near that limit should expect noticeably less than the headline range.
Hills
Climbing draws far more power than cruising on the flat. The 25% maximum incline rating says the scooter can get up a steep hill, not that it can do so without spending range. Commuters with a hilly route should treat the headline number as an upper bound they will not reach.
Cold Weather
Lithium-ion cells deliver less of their capacity in the cold. Xiaomi rates the scooter for -10 to 40 C, but winter range will be shorter than summer range. It recovers once the battery warms back up indoors.
Speed and Throttle Use
Riding at the 25 km/h cap and accelerating hard from every stop uses more energy than a moderate, steady pace. Terrain has the larger effect, but smoother acceleration still extends range.
Charging and Daily Use
With a 561.5 Wh battery and a 124W charger, Xiaomi quotes about 6.5 hours for a full charge, so a scooter plugged in overnight is always full by morning. At about 24.5 kg it is heavy to carry up stairs or onto transit, which matters more than range for many apartment commuters.
Frequently Asked Questions
How much range should I actually expect?
Less than the 43-mile claim. Xiaomi’s figure assumes ideal conditions; a heavier rider, hills, cold weather or riding at top speed each reduce it. Plan a commute around a comfortable fraction of the claim rather than the claim itself.
Does riding style affect range as much as terrain?
Terrain has the larger effect, but smoother acceleration from stops and a moderate speed still meaningfully extend range compared with aggressive throttle use.
Is the Xiaomi 4 Ultra sold in the US?
Not through an official Xiaomi US channel. Units sold in the US are imports of the international version, with its 25 km/h top speed, so check the seller’s warranty terms before buying.
Bottom Line
On paper the 4 Ultra pairs a 500W motor and a 561.5 Wh battery with dual suspension and a 120 kg load rating, which makes it a comfortable, well-equipped commuter. Treat the 43-mile range as a best-case figure, and weigh the 25 km/h cap and the lack of official US sales before you buy.
