Ever wondered why the Ultraviolette F77 feels instant when you twist the throttle?
Why doesn’t it need to roar to scare petrol bikes off the line? It’s not just because it’s electric, it’s because of what’s inside that electric.
Let’s take a proper look at the science under the tank. We’re going to break it all down: the motor, the battery, the torque magic, even the software brain.
And once you get the full picture, you’ll never look at petrol bikes the same way again.
Instant Power: The Physics Behind Electric Acceleration

Here’s the big truth no one tells you, electric motors don’t build up power, they give it instantly. There’s no waiting for the engine to reach peak RPM, no gear lag, no clutch slip.
The F77 uses a Permanent Magnet AC Motor (PMAC), and this tech is one of the biggest reasons behind its insane performance. Let’s understand this motor in simple terms.
What’s a PMAC motor?
It’s a type of electric motor where magnets are built into the rotor (the spinning part). Unlike regular motors that need electrical current to create a magnetic field in the rotor, PMAC motors already have strong permanent magnets.
This gives two big benefits:
- Higher efficiency -Less energy is wasted as heat.
- Massive torque at low RPMs—which means you get a real kick in the pants right from zero.
This is why the F77 can do 0 to 60 kmph in just 2.8 seconds, and 0 to 100 in under 8 seconds. You twist, it launches. No drama, no delay. Just raw pull.
Why Torque Beats Horsepower (Especially on Indian Roads)

Let’s clarify something many people get wrong: torque is what you feel.
Horsepower is what helps you at higher speeds. But torque? That’s what pushes you forward when you take off at a traffic light or overtake in tight spots.
The F77 Mach 2 delivers 100 Nm of torque, which is massive for a motorcycle. That too, from zero RPM. No petrol superbike can match that at low speeds.
In real life, this means:
- Quick sprints through traffic
- Zero lag in overtaking
- Confidence in hilly areas and ghats
- Way less gear shifting stress
In fact, since it’s a single-speed direct drive system, there are no gears at all. You ride it like a scooter but it performs like a race bike.
The Battery: Not Just Bigger, Smarter
The F77 comes with a beast of a battery pack, up to 10.3 kWh capacity. That’s bigger than what you find in most electric cars under 10 lakhs.
But here’s the thing, it’s not just about size. It’s about thermal and safety engineering.
Inside the Battery:
- 5-Level Safety System – Mechanical, Thermal, Electrical, Electronic and Software protection.
- All-Aluminum Enclosure – Rated IP67 (water and dust resistant).
- Advanced Battery Management System (BMS) – Controls temperature, power delivery, charge cycles, and even protects against voltage drops.
This system is why you can hammer the F77 in peak Indian heat, and it won’t overheat or shut down.
And in case you’re wondering, range anxiety won’t be your problem. The top-end variant can go up to 323 km (IDC tested) on a single charge. In real-world city rides, expect around 200–250 km, easily.
Smart Regen Braking: A Hidden Superpower

One thing many petrol riders overlook when switching to EVs is regenerative braking. And the F77 doesn’t just have it, it has levels of it.
You get 3 default regen modes and 10 levels of dynamic regenerative braking.
Why does this matter?
- Saves battery every time you decelerate
- Reduces brake wear
- Makes downhill rides feel smooth and controlled
Once you get used to regen, you’ll barely use the physical brakes during daily commutes.
It’s also perfect for city riding where you’re constantly stopping and starting.
Chassis & Handling: Race Feel, Street Ready
What’s the point of all that power if the bike doesn’t hold the road?
Luckily, the F77 is not just about tech, it’s got the mechanicals to match.
Frame
- Steel Trellis Frame with Aluminium Bulkhead – Light and strong
- Front Suspension – 41 mm Upside-down Telescopic Fork (preload adjustable)
- Rear Suspension – Monoshock (also preload adjustable)
This setup gives you sharp handling, planted cornering, and confidence at high speeds. Whether you’re cornering through Lonavala or navigating potholes in Delhi, the ride feels tight and balanced.
Brakes
- 320 mm front disc
- 230 mm rear disc
- Dual-channel BOSCH ABS
With this, you get serious stopping power, even at 150+ kmph speeds.
Built for India: Smart Charging and Real-World Range

Charging is one of the biggest worries in India, right? Ultraviolette tackled that head-on.
Charging Options:
- Standard charger – 20% to 80% in 3 to 5 hours
- BOOST charger – 20% to 80% in just 1.5 to 2.5 hours
- Supernova DC fast charging – 20% to 80% in 45 minutes
And yes, the F77 uses Type 2 AC car charging standards, which are now very common in India. You can charge it at most EV stations in cities.
For regular use, just plug it in at night and you’re good to go the next day.
The Digital Side: Where Software Meets Speed
We’ve spoken about motor, torque, and battery. But here’s where the F77 truly goes next level, the brain behind the beast.
Violette AI
This is Ultraviolette’s in-house software system that brings smart features to your ride:
- Daily Ride Analytics – Tracks your rides, energy used, regen stats and more.
- Crash Alerts & Lockdown – Sends alerts to your phone if the bike falls or gets tampered with.
- Find My F77 – GPS tracking so you never lose it.
- Delta Watch – Monitors system health in real-time.
You also get:
- 5-inch TFT Display with Parallax & Radar console themes
- Ride-by-wire throttle
- Glide, Combat and Ballistic Modes – Like eco, city, and sport, but more fun
And it runs on UV’s Automotive Linux OS, which is rock solid and future-ready.
Why the F77 Feels So Different to Ride

You know that feeling when you ride a petrol bike and shift gears just right, and the engine sings in tune with your wrist?
Now imagine that, but without the gears. Just twist and go.
That’s what the F77 offers.
It’s smoother, quicker, and more intelligent. There’s no chain snatch, no clutch slip, no gear grinding. Just pure, focused performance.
Also, thanks to traction control, hill hold, and dynamic stability control, it behaves like a premium sports car on two wheels. You can push it hard and still feel safe.
Design That Matches the Engineering
Let’s be honest, performance is sexy, but design seals the deal.
The F77 doesn’t look like a regular EV. It’s jet-inspired, with Aero Surfaces, sculpted bodywork, and colours like Afterburner Yellow, Turbo Red, and Cosmic Black.
Whether parked or in motion, it’s a serious attention magnet.
And it’s got practical touches too, LED headlamps, hazard lights, side-stand sensor, deep sleep battery mode, even auto-dimming dash.
It’s designed not just to ride, but to live with.
This Isn’t the Future, It’s the New Present
