Origin

Xiaomi announced Series 4 in late 2022 with four tiers (Lite / base / Pro / Ultra). The Ultra was positioned from day one as the no-compromise consumer flagship — Xiaomi's direct positional answer to Segway-Ninebot's KickScooter Max G2. The two scooters are factory-siblings: both built by Ninebot under contract, both targeting the €900-1100 'serious commuter' segment, both launching in EU markets within months of each other in 2023. The 4 Ultra exists because the 4 Pro, while massively successful, ceded the premium segment to Segway — Xiaomi needed an answer at the top.

Specifications

Weight: kg
Brakes: Front E-ABS regenerative (electronic) + rear hydraulic disc (140 mm rotor).

The verdict

+Strengths

Dual suspension transforms ride quality vs rigid 4 Pro — usable on cobblestone and gravel
Hydraulic rear disc — shorter, more consistent stopping
940 Wh battery — genuine full-week commute range
IP55 dust+water rating — best in Xiaomi line
Self-repairing tubeless tires near-eliminate pothole flats

−Weaknesses

24 kg — heaviest in Xiaomi line, hard for apartment-dwellers
9-hour charge from stock 168 W charger
No built-in turn signals on EU SKU
Internal non-removable battery — no quick swap
€300-500 premium over 4 Pro

Did you know

01The Mi Scooter line is manufactured by Ninebot (Segway-Ninebot Group) under contract. Frame engineering, motor sourcing, BMS firmware, and the rear suspension elastomer assembly on the 4 Ultra are shared with Ninebot's own Max G2 — the visible-to-consumer differences (frame branding, app, color trim) are Xiaomi-specific; the mechanical guts are largely the same factory.
02The 940 Wh battery is the largest Xiaomi has ever shipped in a consumer scooter — more than 2x the 446 Wh of the 4 Pro.
03Fingerprint unlock module is standard on China-market 4 Ultra. EU SKUs vary by retailer — verify before purchase if the feature matters. Module uses capacitive sensing in the stem cap.
04Self-repairing tubeless tires use the same sealant chemistry as mountain-bike tubeless setups — seals punctures up to ~6 mm but ineffective on sidewall cuts.
05Despite being premium-tier, the 4 Ultra is firmware-capped to 25 km/h in EU. Owners who want unlocked speeds in non-EU markets can flash China firmware via ScooterHacking tools, but this voids warranty and is illegal on EU public roads.
06Dual suspension (front spring + rear elastomer) is engineered for paved roads and well-packed paths, not off-road. Don't confuse the Ultra with an all-terrain scooter — the rated tire pressure (45-55 psi) and unsealed underside are city-spec.
07EU launch units shipped without turn signals despite the China unit having them. Xiaomi cited 'differing regional preferences' but EU reviewers consistently called this a meaningful omission for a premium scooter.
08The 168W charger is meaningfully larger than the 4 Pro's 71W brick but isn't a 'fast charger' — the 9-hour full-charge time is dictated by the BMS's cell-balancing protocol, not raw wattage.
09Hidden 'Off-road' mode appeared in some 2024 firmware versions — softens regenerative braking for loose surfaces. Toggled via app only, not on the dashboard.
10Despite being assembled by Ninebot, the 4 Ultra is service-supported by Xiaomi's own Authorized Service Center network in EU, NOT by Segway. Warranty claims, replacement parts, and firmware updates all go through Xiaomi channels.

Buyer’s notes

№ 01

Claimed 70 km range is more honest than most consumer scooters — realistically expect 50 km in moderate conditions, 35-40 km in cold. The Ultra is the closest sub-€1100 scooter to its marketing number.

№ 02

Before purchase verify: does the specific SKU include fingerprint unlock? EU batches vary — ask the retailer explicitly.

№ 03

24 kg is serious weight. If you live on the 3rd+ floor without elevator — think twice, or plan to buy a folding hand-cart (€30-50) at the same time. Many Baltic owners store the Ultra in a ground-floor bike room.

№ 04

Battery is NOT removable. If you need a spare battery for long rides — look at the Segway Max G2 (offers an accessory secondary battery).

№ 05

IP55 — rain and dust OK, but NOT submersion. Don't ride through deep puddles, don't pressure-wash. The battery compartment gasket is Xiaomi's #1 engineering fix vs the 4 Pro — don't damage it.

№ 06

Top of the theft chart for premium scooters in Tallinn / Riga / Vilnius. Minimum security: U-lock through the wheel + Apple AirTag in the frame. Never leave a €1000 scooter on the street overnight.

№ 07

Winter below -5°C drops battery capacity 25-40% (better than 4 Pro thanks to 21700 cells, but still drops). Real winter range 30-40 km. Many Baltic owners store for winter.

№ 08

Used 4 Ultra 2023 at €650-800 — excellent option if you verify: (1) hydraulics feel (squeeze brake — no sponge), (2) tire sealant condition, (3) battery cycles via Xiaomi Home app, (4) rear elastomer condition.

№ 09

Hydraulic brake needs bleeding every 2 years — €20-30 at a scooter shop. Don't panic if you feel sponge at 18-24 months, that's normal.

№ 10

Compare against Segway Max G2 (€999-1099) — essentially same factory, similar spec, €100-150 difference and app preference. At equal price pick by app preference.

№ 11

CFW (custom firmware) unlocks ~35 km/h — but this is illegal on EU public roads and voids warranty. Not recommended.

№ 12

Alternatives at similar price: Segway Max G2 (€999), Pure Advance (€1099), Okai Neon Pro (€899). Xiaomi wins on spec/price/Baltic service availability balance.
