If you’ve been watching India’s electric two-wheeler space (and who hasn’t lately?), you’d have seen a lot of noise but not always a lot of substance. Oben Electric, a home-grown startup, seems to be trying to break that pattern. This week it pulled the wraps off the Rorr EZ Sigma, the latest version of its flagship bike. On paper it promises a 175 km range, smarter tech, and a few tweaks you might not expect at this price.
I’ve spent the last few days poking around the specs, chatting with dealers, and reading early user chatter. What follows is a closer look at what this bike actually brings to the table — and why it’s probably going to matter.
A Fresh Take on the Same Formula
Oben’s earlier Rorr models had one big selling point: they weren’t toy EVs, they were usable daily rides. With the Sigma, the company is keeping the same silhouette but fiddling with just about everything under the skin. The bike now comes with two battery options — a 3.4 kWh pack and a beefier 4.4 kWh unit. Depending on which you go for, Oben claims up to 175 km of range under IDC testing.
IDC numbers, of course, are always a bit rosy. In real traffic, you’re likely to see less, but even if it’s 140-150 km, that’s still a healthy jump from where commuter EVs were even two years ago.
Modes, Speed and All the Tech Toys
One of the funnier things about EV bikes is how they’ve borrowed language from high-end cars. The Rorr EZ Sigma has three “modes”: Eco, City and Havoc. Yes, Havoc. In practice, it just changes how fast the bike pulls and how much battery it gulps down. Top speed is around 95 km/,h and 0-40 km/h takes 3.3 seconds — quick enough to zip out of a jam but not a drag racer.
What’s actually more useful is the reverse mode, which lets you ease the bike backwards while parking. It’s a small feature that becomes a lifesaver in tight basements and crowded lanes. I’ve wondered for years why more manufacturers don’t include it.
Then there’s the dash: a five-inch TFT colour display that does more than show speed and battery. Navigation, incoming calls, even music alerts — all the little things that make it feel like a modern machine rather than an e-scooter with pedals chopped off.
Comfort and Build: Less Flash, More Thought
I liked what Oben has done with the seat and suspension. The company has quietly raised the ground clearance to 200 mm, fitted chunkier 130/70-17 tyres and a seven-step adjustable rear mono-shock. It’s not glamorous, but it’s the stuff you notice on pothole days or when you’re carrying a passenger.
Water-wading depth is listed at 230 mm. In plain English, that means you’re less likely to panic in knee-deep monsoon puddles. For a bike aimed at Indian cities, that’s a sensible brag.
Safety and Battery Tech: The Unsexy but Important Bits
Oben keeps touting its LFP battery chemistry — Lithium Iron Phosphate — which is generally safer and more heat-resistant than the NMC cells many rivals use. If you live in a hot city or park your bike outside, that matters more than you’d think.
They’ve also added unified brake assist (UBA), a driver alert system, geo-fencing, a battery lock and some anti-vandalism measures. Are these things perfect? Probably not. But they’re signals that Oben knows safety and theft protection are real buyer anxieties.
Charging from zero to 80 per cent takes around 1.5 hours on the faster charger. Not lightning-quick, but a solid step up from overnight charging.
Pricing, Booking and the Fine Print
Here’s where Oben is trying to be aggressive. The 3.4 kWh variant launches at ₹1.27 lakh ex-showroom and the 4.4 kWh version at ₹1.37 lakh — introductory prices. They’ll creep up later to somewhere in the ₹1.47-₹1.55 lakh range. Bookings are open for a token of ₹2,999, with deliveries promised from August 15.
Financing looks reasonable too: EMIs from ₹2,999/month. If Oben keeps that line, it could tempt a lot of ICE-bike owners thinking about switching.
Why This Bike Matters in the Bigger Picture
It’s easy to dismiss each new EV bike as “just another one,” but the Sigma marks a few subtle shifts:
- Range anxiety is being tackled head-on. Even if real-world numbers are lower, a headline 175 km claim builds confidence.
- Feature creep has become the new normal. Buyers expect TFT screens, app connectivity, and reverse mode now. Oben seems to get that.
- Battery chemistry is a differentiator. By betting on LFP, Oben is quietly telling customers: “We’re safer and more durable in the long run.”
The competition isn’t asleep. Startups like Ather, Ola Electric, and a growing bunch of mid-tier brands are all fighting for the same commuter EV buyer. Sigma is Oben’s bid to stand out without going luxury.
Things That Could Still Trip Them Up
I’d be remiss not to mention the possible pitfalls. IDC range vs the real world is always a question mark. Charging infrastructure, especially outside metros, remains patchy. Service networks for newer players like Oben are still thin compared to legacy brands.
And then there’s price creep: after the launch window, the bike will cost more. In a price-sensitive segment, that can hurt momentum unless the value proposition is rock solid.
My Two Paise
As someone who’s been following India’s EV two-wheeler scene since the early lead-acid days, I find the Sigma a genuinely interesting launch. It doesn’t shout with crazy specs but instead quietly fixes the things that make or break daily commuting: range, comfort, and small conveniences.
If Oben can deliver on service and reliability, the Sigma could be one of those turning-point products that make mainstream commuters say, “Okay, maybe I’ll ditch my petrol bike now.”

What to Watch in the Months Ahead
Early owner feedback will be key — not just about range but about how the bike feels after a few thousand kilometres. Will the app stay bug-free? Will the after-sales support match the marketing promises?
It’s also worth seeing how Oben handles expansion into Tier-2 and Tier-3 cities. That’s where EVs are tested hardest — in power cuts, in monsoon conditions, on roads that aren’t photo-shoot ready.
Finally, keep an eye on resale values. Battery warranties help, but perceptions matter, and buyers are still figuring out what used EV bikes are worth.
Bottom Line
Oben Electric’s Rorr EZ Sigma feels like more than a routine upgrade. It’s a sign that India’s EV motorcycle market is maturing: longer ranges, safer batteries, smarter features, all wrapped in a commuter-friendly package.
It may not be perfect — no EV launch is — but it’s one of the first bikes in its segment that seems to have been designed with day-to-day riders front and centre. If Oben executes well, the Sigma could be the bike that convinces a lot of fence-sitters that the electric future is not just inevitable but actually practical.
