Razor_E_Prime_III Review: Detailed Test & Analysis (2026)

TL;DR Quick Look

• Ultra-Lightweight: At 24.2 lbs (11 kg), it is significantly lighter than most adult commuter scooters.
• Braking Safety Concern: Relies solely on an electronic thumb brake and a stomp fender; no mechanical lever brake.
• Ride Comfort Mixed: Features an 8-inch pneumatic front tire for bumps but a solid rear tire that transmits vibration.
• Respectable Top Speed: Hits 18 mph, which is surprisingly fast for this weight class.
• Limited Power: The 250W motor struggles on anything other than flat ground.

Razor E Prime III Specs

Razor E Prime III Real-World Performance

The performance of the Razor E Prime III is defined by its 250W motor, which places it firmly in the "last-mile" category rather than a full commuter vehicle.

Acceleration & Hill Climb:
While official specs promise 18 mph, the 250W motor lacks torque. TechGearLab's review team noted that during testing, the scooter maintained a speed of approximately 12 mph for the majority of their range test loop. On Reddit, users describe the scooter as suitable only for cities that are "flat as a pancake," indicating that it struggles significantly on inclines. We currently lack instrumented 0-15 mph acceleration data.

Top Speed:
Razor claims a top speed of 18 mph. In ideal conditions (flat ground, lighter rider), this is achievable, but heavier riders (near the 220 lb limit) will likely experience speed drop-offs, especially as the battery voltage sags.

Razor E Prime III Range Test

The official Razor E Prime III specifications claim a 15-mile range. However, real-world physics rarely aligns with manufacturer estimates.

Official vs. Reality:
Razor states the battery lasts for "up to 40 minutes" of continuous use or 15 miles. TechGearLab observed that to achieve reasonable distance, the speed often hovered around 12 mph rather than the top speed.

Data Missing:
Our specific real-world range test data (Standardized 75kg rider, urban loop) is currently unavailable for this model. Based on battery voltage (36V) and motor size, we estimate a realistic range of 8–10 miles for an average adult male, but this is a theoretical projection.

Razor E Prime III Ride Quality & Ergonomics

Suspension and Tires:
The ride quality relies entirely on the tires. The front features an 8-inch pneumatic (air-filled) tire, which helps absorb cracks and small bumps. However, the rear is an airless (solid) tire housing the motor. This hybrid setup means your hands might feel okay, but your feet and knees will feel every vibration from the rear wheel.

Portability:
This is the scooter's "Super Power." Weighing just 24.2 lbs (11 kg), it is incredibly easy to fold and carry onto a bus or subway. Gizmodo's review highlighted that while it is sturdy, the folding mechanism is designed for portability above all else.

Razor E Prime III Safety & Braking

This is the most controversial aspect of the Razor E Prime III.

Braking System:
The scooter lacks a mechanical handbrake (disc or drum). Instead, it uses:
1. Electronic Thumb Paddle: Activates regenerative braking.
2. Rear Fender Brake: Requires the rider to shift weight back and stomp on the mudguard.

Safety Concerns:
Reddit users on r/ElectricScooters have strongly criticized this setup. One detailed thread highlights that "stopping distances with the e-brake are awful" compared to mechanical brakes, especially at speeds of 15-18 mph. In an emergency panic stop, relying on a stomp brake takes precious seconds to shift stance, which increases stopping distance significantly compared to squeezing a lever.

Lighting:
It includes an LED headlight and a brake-activated taillight, which is an improvement over previous generations, but visibility remains basic.

Razor E Prime III Reliability & Support

Razor is a heritage brand in the scooter space, meaning parts availability is generally better than generic clones. However, the E Prime III occupies a budget tier.
- Tires: The rear solid tire is maintenance-free (cannot go flat), but the front pneumatic tire will require regular pressure checks.
- User Feedback: Reddit community feedback suggests that while the frame is decent, the lack of suspension and solid rear tire can lead to rattling over time on rough pavements.

Razor E Prime III Competitor Comparison

Razor E Prime III Who Should Buy

• Multi-Modal Commuters: People who need to fold the scooter and carry it onto a crowded train or bus daily.
• Walk-Up Apartment Dwellers: If you live on the 4th floor with no elevator, the 24.2 lb weight is a lifesaver.
• Flat City Riders: Those living in areas with zero hills who only need to travel 1-3 miles.

Razor E Prime III Who Should Not Buy

• Safety-Conscious Riders: The lack of a mechanical brake lever is a significant safety omission for traffic riding.
• Heavy Riders: The 250W motor will struggle to move 200+ lbs swiftly.
• Hill Dwellers: It will not climb moderate inclines without kick assistance.
• Rain Riders: No IP rating is officially advertised, and the solid rear tire offers poor traction on wet asphalt.

FAQ

Is the Razor E Prime III waterproof?

Razor does not officially list an IP (Ingress Protection) rating for the E Prime III. In the electric scooter industry, if a rating is not claimed, it is safest to assume the device is not waterproof. Riding in rain is not recommended due to potential electrical damage and the poor traction of the solid rear tire.

How fast does the Razor E Prime III go?

The official top speed is 18 mph (29 km/h). However, real-world tests by TechGearLab indicate that maintaining this speed depletes the battery quickly, and riders may find themselves averaging closer to 12 mph during longer commutes.

Does the Razor E Prime III have a mechanical brake?

No. The Razor E Prime III relies on an electronic thumb paddle for regenerative braking and a manual rear fender stomp brake. It does not have a bicycle-style hand lever for disc or drum brakes, which some users find less safe for emergency stops.

What is the real range of the Razor E Prime III?

While Razor claims 15 miles, real-world range for electric scooters is typically 60-70% of the claimed figure depending on rider weight and terrain. Expect approximately 8 to 10 miles of usable range under normal urban conditions.

Can the Razor E Prime III climb hills?

With a 250W motor, this scooter is not designed for hills. It will handle very slight inclines, but significant hills will likely require you to kick-push to assist the motor or walk the scooter.

How much does the Razor E Prime III weigh?

It weighs 24.2 lbs (11 kg). This is its standout feature, making it one of the lightest adult electric scooters capable of reaching 18 mph.
