Segway Ninebot ES4 Review High-Range Entry-Level Electric Scooter
The Segway Ninebot ES4 is a sporty, high-range entry-level electric scooter that essentially takes the popular ES2 platform and adds a second external battery pack from the factory. Designed for urban riders who want extended distance and zero-flat-tire convenience, it delivers strong range and respectable top speed on smooth pavement. However, its solid rubber tires and limited suspension create a notoriously harsh ride on anything less than perfect surfaces.
Although the ES series is an older generation compared with today’s pneumatic-tire models, the ES4 still offers useful lessons about the trade-offs between range, maintenance, and comfort. This review examines its real-world performance, strengths, limitations, and ideal use cases.
What Electric Scooters Are and Their Role in Urban Mobility
Electric scooters are compact, battery-powered personal vehicles with a standing deck and handlebars. They provide an efficient last-mile solution for city commuting, short errands, and multimodal travel when combined with public transit. Entry-level models prioritize affordability, portability, and simplicity, while higher-end versions emphasize range, suspension, and power.
The Segway Ninebot ES4 sits in the entry-to-mid range of that spectrum, focusing on battery capacity rather than refined ride quality.
Types of Electric Scooters
- Entry-level solid-tire scooters – Low maintenance, puncture-proof, often harsher ride.
- Commuter pneumatic-tire scooters – Better comfort and grip, require occasional tire care.
- Performance and long-range models – Higher power, advanced suspension, and larger batteries.
The ES4 belongs to the first category, enhanced by its dual-battery design for greater distance.
Performance, Motor, and Speed
The scooter uses a 300 W nominal motor with 800 W peak output. Three riding modes allow riders to balance speed and efficiency. Top speed reaches 18.6 mph (30 km/h).
Testers have noted that the ES4 remains relatively stable at its maximum velocity and resists speed wobbles better than some contemporaries. Acceleration is adequate for urban traffic on flat ground, though hills reduce performance noticeably, as is common with this power level.
Battery Capacity, Range, and Charging
The dual-battery setup is the ES4’s standout feature. By combining the internal battery with an external pack mounted on the stem, the scooter achieves a manufacturer-rated maximum range of up to 28 miles (45 km) under ideal conditions.
Real-world results vary with rider weight, speed, temperature, and terrain, but the extra capacity allows longer commutes or multi-stop trips without midday charging. The external battery can also be removed if desired, returning the scooter closer to ES2 weight and range.
Tires, Suspension, and Ride Quality
The Segway Ninebot ES4 uses solid, non-pneumatic rubber tires—8-inch front and approximately 7.5-inch rear. These eliminate the risk of flat tires and reduce maintenance, a clear advantage for riders who dislike patching tubes.
The trade-off is significant. Without air cushioning, every crack, seam, and small obstacle transmits vibration directly through the deck and handlebars. The dual-spring front suspension helps somewhat but frequently bottoms out on sharper bumps and can produce a noticeable clacking noise. Reviewers consistently describe the ride as harsh on anything other than smooth bike paths or pristine pavement.
Wet traction is also limited. The solid tires offer a smaller contact patch and less grip on wet asphalt or light sand compared with pneumatic alternatives.
Braking System and Safety
Braking relies on an electronic regenerative front brake operated by a thumb lever, paired with a physical rear fender stomp brake. Stopping distances are longer than those of scooters equipped with mechanical disc brakes. Riders must plan ahead, especially at higher speeds or on wet surfaces.
Under-deck LED lighting, controllable via the Segway-Ninebot app, improves nighttime visibility and allows color customization. The scooter’s relatively light weight of about 31 lbs (14 kg) aids portability for carrying onto transit or storing indoors.
Real-World Usability and Ownership
On smooth urban routes the ES4 performs well as a long-range, low-maintenance cruiser. The dual batteries reduce range anxiety, and the solid tires remove puncture worries. App connectivity supports basic monitoring, mode selection, and lighting control.
On broken concrete, expansion joints, or rough sidewalks, the jarring ride becomes fatiguing. Riders with sensitive joints or longer daily distances on imperfect surfaces often prefer models with air-filled tires. Hill climbing is modest, and the electronic brake requires careful technique.
Maintenance is minimal—primarily cleaning, checking the external battery connection, and occasional software updates. Ownership costs remain low thanks to solid tires and efficient dual-battery operation.
Comparison with Related Models
The ES4 is most meaningfully compared with its sibling ES2 and the later Max series, which addressed many of the comfort limitations.
Quick Comparison Table
| Feature | Segway Ninebot ES4 | Segway Ninebot ES2 | Segway Ninebot Max (typical) |
|---|---|---|---|
| Top Speed | 18.6 mph | ~15.5 mph | ~18.6 mph |
| Claimed Range | Up to 28 miles (dual battery) | Lower (single battery) | ~25–40+ miles (depending on version) |
| Motor | 300 W nominal / 800 W peak | 300 W nominal | Higher continuous / peak power |
| Tires | Solid (8″ front / 7.5″ rear) | Solid | Pneumatic (larger diameter) |
| Suspension | Dual-spring front (limited) | Similar limited | Improved or none (model dependent) |
| Weight | ~31 lbs | Lighter (~27–28 lbs) | Heavier (~40+ lbs) |
| Brakes | Electronic + rear stomp | Electronic + rear stomp | Often disc + electronic |
| Best For | Smooth pavement, max range, zero flats | Lighter weight, lower cost | Better comfort and all-around use |
Pros and Cons Summary
Major Pros
- Excellent range from dual-battery design
- Zero flat-tire risk with solid rubber tires
- Stable at top speed
- Customizable under-deck LED lighting via app
- Moderately portable at ~31 lbs
Critical Drawbacks
- Harsh, jarring ride on uneven surfaces
- Limited wet-weather traction
- Longer stopping distances with electronic + stomp brakes
- Suspension can bottom out and produce noise
Buying Recommendation and Market Context
The Segway Ninebot ES4 makes the most sense for riders whose routes are predominantly smooth bike lanes or well-maintained pavement and who prioritize range and puncture resistance over comfort. In those conditions the dual batteries and maintenance-free tires deliver genuine value.
For any commute involving broken sidewalks, gravel, or frequent rough patches, a pneumatic-tire model such as the Segway Ninebot Max series (or modern equivalents) is strongly preferable to reduce vibration and improve grip and braking confidence.
As an older platform, the ES4 is best viewed as a capable but specialized option rather than a current benchmark. Newer scooters have largely solved the ride-quality issues that limited the ES series.
The Segway Ninebot ES4 succeeds as a high-range, low-maintenance urban scooter when used on smooth surfaces. Its dual-battery setup and solid tires remove two common pain points—range anxiety and flats—while delivering stable performance at 18.6 mph.
The fundamental compromise is ride comfort. Without pneumatic tires or more sophisticated suspension, every imperfection in the road is felt. Buyers who accept that limitation in exchange for distance and simplicity will find the ES4 functional and practical. Those seeking a more refined daily experience should look to later models with air-filled tires.
