Introduction—A New Age in City Mobility
India’s electric two-wheeler market has grown rapidly in the past few years, with the likes of Ola, Ather, TVS, and Bajaj leading the charge. But among the newer startups that have been creating a lot of interest in recent times is Oben Electric. Their first product, the Oben Rorr, was liked for its aggressive design and exhilarating performance. Today in 2025, the company has geared up a notch with the Oben Rorr EZ Sigma, a feature-packed, smart, and commuter-focused e-bike that can handle Indian roads without a dent in your wallet.
With its aggressive pricing, extended range, faster charging, and smart features like reverse mode, GPS tracking, and an easy-to-read TFT display, the Oben Rorr EZ Sigma is set to be a value-for-money choice for city commuters who want functionality without compromising on looks.
In the course of this review, let us cut it open and analyze its design, features, performance, pricing, and value.
Pricing and Variants—Competitive and Affordable
One of the most significant points of debate of the Oben Rorr EZ Sigma is its price. Oben has astutely brought in two battery packs, providing riders with options based on their needs:
- 3.4 kWh version – At ₹1.27 lakh (launch offer)
- 4.4 kWh version – At ₹1.37 lakh (launch offer)
After the launch offer, these will hike slightly to ₹1.47 lakh and ₹1.55 lakh, respectively.
For booking, customers need to pay only a token amount of ₹2,999, and these conditions are very easy for new EV customers to procure their unit. The deliveries will start from August 15, 2025, which means that the bike will hit the market just prior to the festival season.
Given the feature list, these prices are reasonable compared to the competition, like the Ola S1 Pro, Ather 450 Apex, and TVS X.
Design and Build—Bold But Practical
At first glance, the Oben Rorr EZ Sigma stands out from most e-bikes and scooters with its massive motorcycle-style look. Instead of a sleek scooter shape, it takes on a street-bike profile with angular lines and aggressive graphics.
Highlights include:
- New “Electric Red” color option with new 2025 graphics.
- Ergonomic, re-engineered seat offering better comfort for rider and pillion.
- It has 200 mm of ground clearance and 230 mm of water wading capacity, so it can go through Indian monsoons and rugged roads.
- ARX frame construction for added ruggedness.
Overall, Oben has done a great job balancing fashion and functionality so the bike is attractive to young buyers without sacrificing usability for everyday use.
Performance and Battery Options
Performance is where the Oben Rorr EZ Sigma really shines. It is powered by LFP (Lithium Iron Phosphate) batteries with MHX thermal technology, not just enhancing heat resistance but also extending the life of the battery to twice that of standard NMC batteries.
This is a comparison of the two battery models:
- 3.4 kWh model – Offers up to 140 km IDC range
- 4.4 kWh model – Demonstrates range up to 175 km IDC
Figures of merit as a commuter:
- Acceleration: 0–40 km/h in 3.3 seconds
- Top speed: 95 km/h
- Torque: ~52 Nm (one of the highest in its class)
This means acceleration off the line is quick, perfect for being in traffic, but still capable of coping with short highway jaunts.
Charging times are convenient too:
- 0–80% within 1.5 hours using a fast charger.
This means as little time standing around as possible, and it’s perfect for city commuters.
Smart Features – A Connected Ride
The other key selling point of the Oben Rorr EZ Sigma is its technology-laden, feature-heavy feature list. Oben has very clearly designed it as an EV, but also as a connected commuter pal.
Some of the standout features are
- Reverse Mode – Parking and navigating through tight spaces is a cakewalk.
- 5-inch TFT Color Display—Offers navigation, call & message alerts, music operation, and trip data. The display is designed to stay legible even in harsh sunlight conditions.
- Oben Electric App (free for 1 year)—Offers smart features like
- GPS location and Find My Rorr
- Geo-fencing for security
- Remote diagnosis
- Anti-theft alarms and remote lock
- Access to 68,000+ charging points via Oben Net
This makes the Rorr EZ Sigma more feature-rich than most of its competitors in the same price bracket.
Safety and Ride Comfort
In order to accommodate Indian road conditions, Oben has included some thoughtful features:
- Unified Brake Assist (UBA) for safe braking.
- Driver Alert System (DAS) to assist riders to remain alert.
- 7-step mono-shock suspension, which is adjustable according to road conditions.
- Roomy 130/70-17 tires that offer better grip and stability.
- Protection from vandalism and geo-fencing theft protection.
These features not only make the bike perform well but also offer the rider safety and comfort.
How Does It Compare?
Compared to its competitors, like the Ola S1 Pro, Ather 450 Apex, and TVS X, the Oben Rorr EZ Sigma finds a niche for itself.
It’s more of a motorbike than a scooter, something that will appeal to younger riders who require the sporty posture.
Its reverse mode, TFT screen, and app connectivity put it on par with its competition feature-wise.
At a 140–175 km range, it falls squarely in the commute sweet spot.
It’s cheaper than many of its premium counterparts, so it’s a value buy for budget-conscious buyers.
Final Verdict—Is the Oben Rorr EZ Sigma Worth Buying?
Oben Rorr EZ Sigma is a self-assured step forward by Oben Electric. Its bold appearance, robust construction, useful performance, and feature-rich package check almost all the right boxes for a modern commuter EV bike.
Its combination of rapid charging, 95 km/h maximum speed, reverse gear mode, TFT display, and smartphone-driven smart features positions it in an extremely compelling zone in the ₹1.3–1.5 lakh range.
If you desire an electric bike that is more than just a scooter and gives the motorcycle riding experience but without the drawbacks of conventional technology, the Oben Rorr EZ Sigma is one of the best choices in 2025.
Key Takeaways
- Range choices: 140 km & 175 km
- Launch price: ₹1.27 lakh – ₹1.37 lakh
- Max speed: 95 km/h
- 0–80% charge in 1.5 hrs

The electric vehicle segment is heating up, and Oben has taken its serious place with the Rorr EZ Sigma in the mid-size electric motorbike segment and can be considered as best EV bike.
