Electric bike maker Ultraviolette's net loss surged 89% to INR 116.3 crore in FY25, even as operating revenue more than doubled to INR 32.3 crore. Rising expenses, particularly in advertising and R&D, contributed to the increased loss. The company, backed by TVS Motor Company, secured $21 million in funding from TDK Ventures and is pursuing aggressive global expansion in India and Europe.
