I’ve been following electric two-wheelers closely, and the Ultraviolette Tesseract 2025 is one of the most interesting models this year. In this post I’ll walk you through what the bike offers for performance, battery options and real-world range. I’ll use plain language, clear numbers, and real examples so you can see which variant might fit your ride.
Battery variants and claimed ranges
Ultraviolette offers the Tesseract in three battery sizes: 3.5 kWh, 5 kWh and 6 kWh. The company lists IDC-certified ranges for each variant as roughly 162 km, 220 km and 261 km respectively. Those are strong numbers on paper.
Important details from the maker:
- The battery family is called SRB-6 and comes with an 8-year warranty.
- Fast charging is supported via Ultraviolette’s Supernova fast charger; company claims ~20–80% in under 30 minutes, and some outlets report 0–80% in under an hour.
- There are three battery choices to match different needs: city commuting, mixed use, or long-range touring.
Performance: power, speed and sprint times
For performance, the Tesseract is tuned for sporty rides. The motor’s peak is around 20 bhp (≈14.9 kW). Ultraviolette claims a top speed of about 125 km/h and a 0–60 km/h time of roughly 2.9 seconds on the higher-spec variant. That 0–60 time puts it in a quick class for electric bikes focused on urban and highway bursts.
In practical terms, the Tesseract will comfortably overtake traffic and keep up with highway speeds. But remember: holding high speed drains energy faster. If you ride at the top speed a lot, your range will fall below the IDC numbers.
Real-world range: what to expect
Manufacturer IDC figures are useful for comparison, but real-world range depends on many factors: rider weight, speed, terrain, weather and how much you use features like traction modes or ADAS alerts. Here are reasonable real-world estimates based on the IDC claims and typical losses you see in owner tests:
| Variant | Battery (kWh) | IDC Range (km) | Estimated Real-world Range (km) | 0–60 km/h | Charge 20–80% |
|---|---|---|---|---|---|
| Urban | 3.5 kWh | ~162 km | ~110–130 km | ~3.5–4.0 s | ~20–40 min (fast) |
| Mid | 5 kWh | ~220 km | ~150–180 km | ~3.0–3.2 s | ~25–45 min (fast) |
| Long‑range | 6 kWh | ~261 km | ~180–220 km | ~2.9 s | ~25–50 min (fast) |
The ranges in the table show a typical drop of about 20–30% from IDC in mixed riding. If you mostly ride at steady 60–70 km/h and use regen, you’ll be closer to the high end of those estimates. If you often cruise at 100+ km/h, expect larger losses.
Charging, battery life and practical ownership
Charging matters a lot. Ultraviolette’s Supernova fast charger and public DC charging support mean you can get back on the road quickly. The company’s claim of 20–80% in under 30 minutes is realistic under ideal conditions. Many reviewers also note a 0–80% claim of under an hour depending on charger and battery state.
Battery warranty is another plus. The SRB-6 pack family comes with an 8-year warranty, which shows confidence in battery longevity. In my view, that’s a strong selling point—especially if you compare it to many electric two-wheelers that offer shorter battery warranties.
One real-world ownership example: imagine you commute 50 km a day, five days a week (250 km/week). With a 6 kWh Tesseract and careful riding you’d likely do two full days without charging and top up on weekends. With a 3.5 kWh variant you’d need to charge midweek. That simple math helps decide which battery suits you.
Features that affect range and usability
The Tesseract isn’t just about battery size. It also has tech that changes how you use energy:
- Regenerative braking with four levels. More regen can add a few km per charge in city commuting.
- Selectable traction modes that alter power delivery and can save energy if you choose an eco mode.
- ADAS and radar safety suite (blind-spot detection, lane-change/overtake alerts). These improve safety, and some modes can slightly affect energy use.
- A robust chassis and 14-inch wheels. The bike is heavier than a small scooter, which helps stability but affects energy consumption at very low speeds or during frequent stop-start traffic.
So if you often ride in hilly areas or at high speeds, expect a noticeable change in energy usage compared to flat-city commutes.
Price, bookings and availability
Pricing has shifted during the Tesseract’s launch phase. Early offers were reported around ₹1.20 lakh, while later base pricing was cited near ₹1.45 lakh ex-showroom. Demand has been strong — reports mention tens of thousands of bookings, with some outlets noting the model crossed 70,000 bookings.
Deliveries were projected from early 2026, with final variant pricing to be firmed in Q4 2025. If you’re planning to buy, expect to choose between the 3.5, 5 and 6 kWh options based on how far you ride and how often you can charge.
Which variant should you pick?
Here’s how I’d choose:
- If you commute short distances and have daily charging: the 3.5 kWh is lighter and cheaper.
- If you want a balance of range and performance: the 5 kWh fits most riders.
- If you need long range, do long weekend rides, or dislike frequent charging: the 6 kWh is the best fit.
For example, a delivery rider doing 120–150 km daily should aim for the 6 kWh option, while a city commuter doing 30–50 km daily can save money with the 3.5 kWh version.
Final Thoughts
In short, the Ultraviolette Tesseract 2025 is a strong contender in the high-performance electric two-wheeler space. It pairs sporty performance (≈14.9 kW peak, 125 km/h top speed, ~2.9 s 0–60 km/h for top spec) with three clear battery choices (3.5 / 5 / 6 kWh) and impressive IDC ranges (~162 / 220 / 261 km). Fast charging, an 8-year battery warranty, and a safety-rich feature set add real value.
Just remember: IDC numbers are ideal tests. Your real-world range will vary with speed, load, terrain and riding style. If you want help choosing the right variant for your routine, tell me how many kilometers you ride per day and where you ride (city, highway, hills) — I’ll run the numbers with you.
