All-New Oben Rorr EZ Sigma Launched: Reverse Mode & 175 Km Range

Bengaluru-based Oben Electric launched the Rorr EZ Sigma, a significant update to its existing Rorr EZ lineup.

With two battery variants—3.4 kWh and 4.4 kWh—this model aims to address evolving urban commuting needs through targeted hardware and software improvements.

Pricing begins at ₹1.27 lakh for the base model under a limited-time introductory offer.

Key Functional Updates

The Rorr EZ Sigma introduces several practical upgrades over its predecessor. Notable additions include:

• Reverse Mode, which enhances maneuverability in dense urban environments
• 5-inch TFT colour display with support for turn-by-turn navigation, call/message alerts, and music notifications
• Improved seat design for longer ride comfort
• New colour options, including Electric Red

These changes suggest Oben’s intent to blend utility with usability, focusing more on real-world rider interaction than cosmetic enhancement alone.

Performance and Battery Technology

The Rorr EZ Sigma is built on Oben’s proprietary LFP battery technology.

This chemistry is known for its thermal stability, longer lifecycle, and safety—particularly suited for India’s climate conditions. Both variants feature:

• Top Speed: 95 km/h
• Acceleration (0–40 km/h): 3.3 seconds
• On-wheel torque: 286 Nm

Range & Charging

Variant	Range (IDC)	Fast Charging (0-80%)	Normal Charging (0-100%)
3.4 kWh	140 km	1.5 hrs	5 hrs
4.4 kWh	175 km	2 hrs	7 hrs

Ride modes vary the output:

• Eco Mode: 40 km/h with max range
• City Mode: 60 km/h for moderate range
• Havoc Mode: 95 km/h for performance riding

Connectivity and Remote Access

The upgraded Oben Electric app now offers:

• GPS-enabled vehicle location
• Geo-fencing-based theft protection
• Ride analytics and diagnostics
• Charging station locator (network of 68,000+ stations)

These integrations reflect the broader EV industry trend of digitizing vehicle ecosystems to enhance post-sale engagement and control.

Rorr EZ Sigma Design, Safety, and Build

Oben continues using its indigenously developed ARX frame, a platform known for high ground clearance (200 mm) and adaptable suspension.

Additional hardware features include:

• Unified Brake Assist (UBA)
• Driver Alert System (DAS) to indicate power-on state
• Water-wading depth: 230 mm
• Tyres: 110/70-17 (front) and 130/70-17 (rear), tubeless

The inclusion of patented vandalism protection and battery theft lock points to rising concerns around EV safety in urban India.

Conclusion

Oben Electric’s Rorr EZ Sigma represents a maturing EV two-wheeler market in India, where performance is increasingly supplemented by practicality, safety, and smart systems.

While not revolutionary in terms of powertrain, the model is relevant for a city-focused rider who values connected tech, low operating costs, and safety-focused features.

Its arrival just ahead of India’s Independence Day, with a mass-delivery kickoff on August 15, signals both strategic timing and confidence in domestic manufacturing scalability.
