Quick Take
- Ultraviolette will spend Rs 779 Cr over five years on a new plant at Hosur in Tamil Nadu.
- The plant is built for 2.5 lakh electric two-wheelers a year and can stretch to 5 lakh.
- Ultraviolette sells about 700 vehicles a month now. Stage one at Hosur needs about 20,800.
Ultraviolette will spend Rs 779 Cr on a new plant at Hosur in Tamil Nadu, the electric bike maker said on September 10, 2026.
The Ultraviolette Hosur factory is called BIGGA, short for Big Global Ambition. It will build 2.5 lakh electric two-wheelers a year. The frame is designed to take 5 lakh.
Ultraviolette sells about 700 bikes a month today, the firm told Business Standard. Stage one at Hosur works out to about 20,800 a month. StartupFeed did that sum, and the gap is the story.
Narayan Subramaniam, co-founder and chief executive of Ultraviolette, told PTI the money runs over five years. It comes from cash in hand, fresh equity and future cash flow, with limited debt.
What the Ultraviolette Hosur Factory Will Build
The plant sits in the SIPCOT park at Shoolagiri, near Hosur, in Tamil Nadu’s Krishnagiri district. SIPCOT is the state body that builds and runs such parks.
Tamil Nadu’s Electric Vehicles Policy 2023 aims to pull in Rs 50,000 Cr of EV plant money and 1.5 lakh jobs.
Stage one is 2.5 lakh bikes a year. Ultraviolette says the shell can hold gear for 5 lakh a year later.
The first product is the Tesseract, an electric scooter. Bikes in the sports, crossover, cruiser and street classes follow.
About 2,000 jobs come with stage one. That count rises as output grows, the company said.
Inside, the plant uses robots that work beside people on welding and assembly, camera checks on the line, and a test track on site. The Bengaluru plant stays open and keeps its current work.
Business Standard put the plant six to eight months from opening. That points to the first half of 2027.
Where 2.5 Lakh Scooters a Year Would Rank Today
Do the sum and the plan gets clearer. A run rate of 2.5 lakh a year is about 20,800 bikes a month.
Vahan, the road ministry’s vehicle site, is where every new bike gets counted. Autocar Professional put August 2026 registrations at 1,80,569, up 65% on the year.
Against that month, 20,800 a month would have placed Ultraviolette fourth in India. It would sit above Hero MotoCorp and above Ola Electric, and below Ather Energy.
At full stretch the plant reaches 5 lakh a year, or about 41,700 a month. That is just past what Bajaj Auto sold in August.
| Brand | August 2026 registrations | Share |
|---|---|---|
| TVS Motor | 48,873 | 27.1% |
| Bajaj Auto | 41,018 | 22.7% |
| Ather Energy | 28,707 | 15.9% |
| Hero MotoCorp | 18,977 | 10.5% |
| Ola Electric | 13,849 | 7.7% |
| BIGGA plant, stage one | 20,800 (planned) | not yet built |
One more number. Rs 779 Cr buys 2.5 lakh units of yearly capacity, so each unit costs about Rs 31,000 to put in place.
Two States, Two Plans, Six Months Apart
Hosur is not the first plant Ultraviolette has promised this year. In March 2026 the firm signed a deal with Karnataka at the Invest Karnataka meet.
That deal had two stages. Stage one put Rs 200 Cr into the Bengaluru plant. Stage two named a new plant for 1.5 lakh units a year.
M. B. Patil, Karnataka’s minister for large and medium industries, presented the deal. It also proposed help under the central production-linked scheme, and faster clearances.
Six months on, the bigger plant is in Tamil Nadu. Hosur sits just across the Karnataka border, so the Bengaluru team is still within a short drive.
Ultraviolette has also said the Tesseract will be built in Karnataka first, and move to Hosur later. Business Standard carried that plan on September 10.
Add the two together and Ultraviolette has named close to Rs 1,000 Cr and 4 lakh units a year across two states. Neither notice gave that combined figure.
Inc42 wrote on September 11 that company filings show a further Rs 373 Cr coming in, in two tranches of preference shares. Yali Capital and TDK Ventures are among the buyers of those shares.
Why the Tesseract Has to Sell First
All of this rests on one product. The Tesseract was shown in early 2025 and bookings opened at a token of Rs 999.
More than 50,000 people booked in the first two weeks. Prices start at Rs 1.20 lakh, ex-showroom, for the first 10,000 buyers.
Then the dates moved. Ultraviolette’s own Tesseract page now puts deliveries in the first quarter of 2027.
That is about two years after the scooter was first shown. Ultraviolette says it will ramp to 10,000 a month once the Tesseract arrives.
The market is also colder than it was. Under PM E-DRIVE the centre cut the electric two-wheeler grant to Rs 2,500 per kWh, capped at Rs 5,000.
The same order ran the scheme on to March 2028. So the lower grant is what buyers get for the next 18 months.
Inc42 counted a second straight monthly fall in August. So the plant is being built into a softer month, not a rising one.
What this means for you: If you supply parts, tooling or wiring to two-wheeler plants near Hosur and Bengaluru, a new buyer is moving in. Watch the SIPCOT park at Shoolagiri for vendor lists and tenders, because hiring starts at about 2,000 jobs.
StartupFeed Insight
Read the two deals as one plan, not as a switch. Karnataka keeps the old plant, the research work and the first build. Tamil Nadu gets the volume, the land and the 2,000 jobs, because Hosur already has the parts firms and the road links. The risk is timing, not siting. Stage one needs about 20,800 sales a month, and the company sells about 700 a month today. Our call: the BIGGA plant will open with one line and well under half the planned rate. Ultraviolette will not sell 20,000 bikes in a single month before March 2028.
