Xiaomi has built a reputation for delivering solid electric scooters at competitive prices. The Xiaomi scooter 4 Ultra review begins with the specs: a 500W motor, a claimed 45-mile range, and a weight of just 36 lbs. We spent several weeks riding this scooter on daily commutes, weekend errands, and a few steep hills to see if the real-world numbers match the marketing. This review breaks down the design, motor performance, battery life, app experience, and how it stacks up against the Segway MAX G30. Whether you’re a commuter considering your first mid-range e-scooter or an eco-conscious rider tired of car trips, this hands-on analysis will help you decide if the 4 Ultra is worth the $999 investment.
Review methodology: We purchased the Xiaomi Electric Scooter 4 Ultra at retail price. Testing took place over 300 miles of mixed urban riding in temperatures ranging from 45°F to 85°F. Range tests were conducted with a 175 lb rider in Standard mode on flat pavement with occasional stops. Hill climbing was measured on a consistent 12% grade. All data reflects our independent observations.
[table-of-contents]Xiaomi Scooter 4 Ultra Design and Build vs Prior Models
The Xiaomi Electric Scooter 4 Ultra looks familiar at first glance. The folding stem, integrated deck lights, and minimalist dashboard carry over from the Mi M365 lineage. However, the materials have been upgraded. The frame uses a higher-grade aluminum alloy that feels stiffer under load. The folding mechanism now features a dual-latch system that eliminates the slight wobble present in earlier models. At 36 lbs, it is noticeably lighter than the Segway MAX G30 (which weighs roughly 42 lbs). That difference matters when you carry the scooter up apartment stairs or onto a crowded train.
The deck is wider than the Mi Pro 2, giving more foot room for riders with larger shoes. The 10-inch pneumatic tires are tubeless and self-sealing, a welcome upgrade from the tube-type tires on the Mi 3. We ran over a small nail during testing and the sealant held without pressure loss. The IP54 rating means the scooter handles light rain and splashes, but we still avoid deep puddles to protect the battery compartment. The rear fender includes a built-in reflector and a subtle brake light that activates with both the electronic and mechanical brakes.
- Weight: 36 lbs (16.3 kg)
- Frame: Aerospace-grade aluminum alloy
- Tires: 10-inch tubeless pneumatic with self-sealing layer
- Water resistance: IP54
- Folded dimensions: 45.3 x 18.9 x 19.7 inches
500W Motor and Speed Performance
The 500W nominal motor (peak 900W) is the most powerful unit Xiaomi has put in a consumer scooter to date. In Sport mode, the scooter hits the governed top speed of 20 mph quickly. The 0-15 mph sprint takes about 4.2 seconds on flat ground. That acceleration feels smooth because the controller ramps current progressively rather than dumping full torque instantly. This reduces wheel spin on wet pavement and makes the scooter predictable for less experienced riders.
Hill climbing is where the motor shows its strength. On our 12% test grade, the 4 Ultra maintained 12 mph with a 175 lb rider in Sport mode. The same hill dropped the Segway MAX G30 to 9 mph. The motor does get warm after repeated climbs, but the thermal management keeps it within safe limits. We never encountered a thermal throttle during normal commuting. Noise levels are low; the motor produces a faint whine at full throttle that is barely audible over city traffic.
Three speed modes are available: Eco (12 mph), Standard (15.5 mph), and Sport (20 mph). The speed limiter can be adjusted in the app for regions with lower legal limits. Regenerative braking is adjustable in three levels. We found the medium setting to be the best balance of energy recovery and natural coasting feel.
Real-World Range Testing for the Xiaomi 4 Ultra
Xiaomi claims a 45-mile range under ideal conditions. Our real-world range testing consistently delivered 38 miles in Standard mode with a 175 lb rider on mixed urban terrain. That is a respectable 84% of the claimed figure. In Eco mode, we stretched it to 44 miles by avoiding full-throttle starts and keeping speeds under 12 mph. Sport mode with frequent acceleration dropped the range to 28 miles. For commuters planning 10-20 mile round trips, the 38-mile real-world range means you can realistically go 3-4 days between charges on a typical commute route.
The 36V 12.8Ah (460Wh) lithium-ion battery charges from 0-100% in 5.5 hours using the included 2A charger. A fast charger (5A) is sold separately and cuts that time to roughly 2.5 hours. Battery management is handled by a smart BMS that balances cells during charging and protects against over-discharge. After 300 miles, we saw no measurable capacity loss. Long-term degradation data from Xiaomi’s earlier models suggests roughly 10-15% capacity loss after 500 charge cycles. That translates to about two years of daily commuting for most riders. Charging cost is negligible. At the U.S. average electricity rate of $0.16 per kWh, a full charge costs about $0.07, or roughly $0.002 per mile in Standard mode.
| Mode | Tested Range | Top Speed | Best For |
|---|---|---|---|
| Eco | 44 miles | 12 mph | Maximum distance, flat terrain |
| Standard | 38 miles | 15.5 mph | Daily commuting, mixed terrain |
| Sport | 28 miles | 20 mph | Short trips, hilly areas |
App and Smart Features
The Xiaomi Home app (formerly Mi Home) is the control center for the 4 Ultra. Pairing is straightforward: power on the scooter, open the app, and it detects the device via Bluetooth. The dashboard shows speed, battery percentage, mode, and total mileage. You can customize the speed limit for each mode, adjust regenerative braking strength, toggle cruise control, and enable a walking mode that limits speed to 3 mph for pushing alongside you.
Firmware updates are pushed through the app. During our test period, we received one update that improved throttle response at low speeds and fixed a minor bug where the headlight would flicker at very low battery. The app also provides a ride log with distance, average speed, and energy consumption per trip. For tech-forward riders in the 25-55 demographic, the integration with the broader Xiaomi ecosystem (smart home devices, wearables) is a nice bonus. The app is stable on both iOS and Android, though we did experience one brief disconnect that required a re-pair.
- Custom speed limits per mode
- Adjustable regenerative braking (3 levels)
- Cruise control toggle
- Walking mode (3 mph)
- Ride statistics and exportable logs
- Firmware updates over Bluetooth
- Anti-theft alarm with motion detection
Xiaomi 4 Ultra vs Segway MAX G30 Comparison
The Segway MAX G30 has been the benchmark for mid-range commuter scooters. The Xiaomi 4 Ultra challenges it directly. Here is how they compare on the metrics that matter for urban commuting.
| Spec | Xiaomi 4 Ultra | Segway MAX G30 |
|---|---|---|
| Motor (nominal/peak) | 500W / 900W | 350W / 700W |
| Claimed range | 45 miles | 40 miles |
| Real-world range (Standard) | 38 miles | 34 miles |
| Weight | 36 lbs | 42 lbs |
| Top speed (governed) | 20 mph | 18.6 mph |
| Tire type | 10″ tubeless pneumatic | 10″ tubeless pneumatic |
| App ecosystem | Xiaomi Home | Segway-Ninebot |
| Price (MSRP) | $999 | $949 |
The Xiaomi 4 Ultra wins on motor power, top speed, real-world range, and weight. The Segway MAX G30 has a slightly more refined throttle map at very low speeds and a more mature app with better social features. Build quality is comparable; both feel solid. If you prioritize hill climbing, lighter carry weight, and a few extra miles per charge, the Xiaomi is the better choice. If you prefer a softer initial acceleration and a more established service network in North America, the Segway remains a safe pick. For eco-conscious buyers seeking to eliminate car trips, the Xiaomi’s superior range in Standard mode makes multi-trip days more viable.
Who This Xiaomi Scooter Is For
The Xiaomi Electric Scooter 4 Ultra fits a specific rider profile. It excels for the urban commuter who needs a lightweight, powerful scooter that can handle hills, fit on public transit, and last a full work week on a single charge. The app customization appeals to riders who want to fine-tune performance. The 36 lb weight makes it manageable for most adults to carry short distances. The price point sits in the sweet spot between budget models with compromised range and premium scooters that cost $1,500+.
- Commuters with a 10-20 mile round trip
- Riders who encounter steep hills regularly
- Multi-modal travelers (train, bus, car trunk)
- Tech-forward users who appreciate app integration
- First-time buyers wanting a reliable brand with service support
- Eco-conscious riders looking to replace short car trips
It is less ideal for riders over 220 lbs who need maximum range, or for those who frequently ride in heavy rain (IP54 is splash resistant, not waterproof). Off-road capability is limited to smooth gravel paths; the suspension is rigid.
Safety and Braking System
Safety is non-negotiable when testing any personal electric vehicle. The 4 Ultra uses both electronic regenerative braking (via the left thumb lever) and a mechanical drum brake (right lever). Both brakes feel responsive and can be modulated smoothly. Our braking distance from 15 mph on dry pavement was approximately 18 feet. The dual-brake system provides redundancy that matters if electronic components fail. The integrated headlight is adequate for morning commutes but would benefit from higher lumens for night riding. The rear brake light is visible and activates immediately when either brake is engaged. For commuters prioritizing safety, we recommend adding third-party front and rear lights rated for night riding.
Maintenance and Durability
After 300 miles of testing, the scooter required minimal maintenance. The folding latch stayed tight, the bolts did not loosen, and there were no rattles. The self-sealing tires eliminated the need for air-pump visits, though a portable pump is inexpensive insurance for longer rides. Xiaomi provides a one-year warranty covering the battery, motor, and electronics from the purchase date. Extended warranty options are available through retailers. Replacement parts (tires, brake pads, batteries) are available online at moderate cost. Compared to some competitors, Xiaomi’s parts availability is strong, which matters if you plan to keep this scooter beyond the warranty period.
Frequently Asked Questions About the Xiaomi 4 Ultra
Is the Xiaomi scooter 4 Ultra waterproof? No, it has an IP54 rating, meaning it tolerates light rain and splashes but is not waterproof. Avoid riding through puddles or heavy downpours to protect the battery compartment.
Can I use this scooter if I weigh over 200 lbs? Yes, but your range and hill-climbing performance will decrease. Xiaomi rates the 4 Ultra for riders up to 264 lbs, though we recommend testing on varied terrain before committing.
How long does the battery last? The lithium-ion battery typically retains 85-90% of capacity after 500 charge cycles (about 2 years of daily use). Capacity then degrades more slowly, reaching around 80% after 1,000 cycles.
Is the Xiaomi Home app required to operate the scooter? No. The scooter works without the app, but you lose access to mode customization, speed limits, and ride statistics. Basic operation is possible via the handlebar controls alone.
Can I take this on an airplane? Most airlines prohibit lithium-ion battery packs over 100Wh, and this model contains a 460Wh battery. Check with your airline before traveling, as regulations vary by carrier and route.
What is the difference between the 4 Ultra and the Xiaomi 4 Pro? The Pro model uses a 400W motor and smaller 36V 10Ah battery, delivering lower performance and range. The 4 Ultra is the step-up model with the 500W motor and 12.8Ah battery we review here.
Final Verdict
The Xiaomi Electric Scooter 4 Ultra delivers on its core promises. The 500W motor provides strong acceleration and hill climbing that outperforms the segment benchmark. Real-world range of 38 miles is 84% of the claimed figure, which exceeds industry honesty standards. At 36 lbs, it is light enough to carry but substantial enough to feel stable at speed. The app is intuitive for tech-forward riders, and the ecosystem integration appeals to existing Xiaomi users. The $999 MSRP positions it as a premium mid-range scooter, but the performance justifies the price when compared directly to the Segway MAX G30.
This is not the cheapest commuter scooter on the market, but it is one of the most capable. Eco-conscious buyers can confidently use this to replace short car trips, and fitness-minded riders appreciate the consistent performance across varied terrain. The main trade-offs are the lack of suspension (ride comfort on rough pavement is limited) and the IP54 rating (not ideal for daily rain commuting). For commuters in mild climates with smooth roads, the 4 Ultra is a solid investment that will deliver years of reliable service.
Rating: 8.5/10
Recommended for: Urban commuters, hill climates, tech-forward riders, eco-conscious buyers replacing car trips, multi-modal travelers.
Not recommended for: Heavy riders (220+ lbs), daily rain commuting, off-road use, riders seeking suspension comfort.
Where to Buy: The Xiaomi Electric Scooter 4 Ultra is available through Xiaomi’s official store and major retailers including Amazon, Best Buy, and authorized dealers. Price typically ranges from $899 to $1,099 depending on regional availability and seasonal discounts.
