Oberon Rorr EZ Sigma 2025 Electric Bike Review, Launch Overview
The Oberon Rorr EZ Sigma launch in India comes with an introductory ex-showroom price starting at ₹1.27 lakh for the 3.4 kWh variant and ₹1.37 lakh for the 4.4 kWh version. After the introductory period, prices will rise to ₹1.47 lakh and ₹1.55 lakh respectively.
Bookings are open with a token amount of ₹2,999, and deliveries are scheduled to begin from August 15, 2025. Buyers can also expect EMI plans starting from around ₹2,999, making it easier for first-time EV buyers to step in.
Oberon Rorr EZ Sigma Price in India and On-Road Cost
The Oberon Rorr EZ Sigma price in India sits comfortably under the ₹2 lakh mark even after adding insurance and registration in most states. This places it among the best electric bikes under 2 lakh in India, especially for riders looking for motorcycle-style performance rather than scooter convenience.
On-road prices will vary by city, but in Bengaluru, the on-road cost for the 4.4 kWh variant is expected to stay close to ₹1.5 lakh during the introductory phase. Considering the features on offer, the pricing feels competitive.
Oberon Rorr EZ Sigma Battery Details and LFP Technology
One of the standout aspects of the Oberon Rorr EZ Sigma battery details is the use of LFP (Lithium Iron Phosphate) chemistry. Oben is among the few manufacturers in India using LFP batteries in electric motorcycles.
The bike is available with
- 3.4 kWh battery – claimed IDC range of 140 km
- 4.4 kWh battery – claimed IDC range of 175 km
According to Oben, the LFP battery offers about 50% better heat resistance and nearly double the lifecycle compared to conventional NMC batteries. For Indian weather conditions, this focus on thermal stability is a big plus for long-term ownership.
Oberon Rorr EZ Sigma Real World Range Test and Mileage
While IDC figures are useful for comparison, most buyers want to know the Oberon Rorr EZ Sigma mileage real world. Based on riding modes and traffic conditions:
- City riding in Eco mode can realistically deliver 115–130 km on the 3.4 kWh pack
- The 4.4 kWh version can return 145–160 km in mixed city usage
This makes it a practical best EV bike for daily commute, especially for riders covering 30–50 km per day.
Oberon Rorr EZ Sigma Charging Time and Fast Charging
The Oberon Rorr EZ Sigma charging time is another strong point. With fast charging support:
- 0–80% charge takes around 1.5 hours
- The smaller battery can charge slightly quicker, while the larger pack takes close to 2 hours
For daily use, overnight home charging should be enough, while fast charging helps during busy weekdays.
Oberon Rorr EZ Sigma Motor Power, Top Speed and Performance
Both variants use the same electric motor setup
- Motor power: 7.5 kW
- Peak torque: 52 Nm
- Top speed: 95 km/h
The Oberon Rorr EZ Sigma top speed is adequate for city roads and short highway stretches. Acceleration from 0–40 km/h in 3.3 seconds feels quick, especially in Havoc mode, making overtakes easy in urban traffic.
Oberon Rorr EZ Sigma Riding Modes and Features
The bike offers three riding modes
- Eco
- City
- Havoc
The Havoc mode, in particular, delivers sharp throttle response and is fun without feeling aggressive. New additions include a reverse mode, which is genuinely useful while parking in tight spaces.
The 5-inch TFT display supports navigation, call and message alerts, music control, and trip data. Combined with the Oben Electric App, riders get GPS tracking, geo-fencing, remote diagnostics, and anti-theft alerts.
Oberon Rorr EZ Sigma Ownership Cost and Warranty Details
When it comes to Oberon Rorr EZ Sigma ownership cost, electric bikes already have an advantage due to lower running and maintenance expenses. Oben further strengthens this with its Battery Protect 8/80 Plan, offering
- 8 years or 80,000 km battery warranty
- Transferable coverage for better resale value
Routine service intervals are simple, and costs are expected to remain lower than petrol motorcycles in the same segment.
