As of my last update in September 2021, the Ultraviolette F77 was an upcoming electric motorcycle designed and developed by Ultraviolette Automotive, an Indian electric vehicle startup based in Bengaluru, India. The F77 aimed to revolutionize the Indian two-wheeler market by offering a high-performance, electric alternative to traditional gasoline-powered motorcycles. Here's a more detailed description of the bike:

Design and Styling: The Ultraviolette F77 boasts a striking and futuristic design, characterized by sharp lines and aggressive aesthetics. The motorcycle's overall appearance reflects a blend of sportiness and modernity, attracting attention from both motorcycle enthusiasts and eco-conscious consumers.

Powertrain: At the heart of the Ultraviolette F77 is an electric powertrain that consists of a permanent magnet synchronous motor (PMSM) coupled with a high-capacity lithium-ion battery pack. The electric motor delivers instant torque, providing exhilarating acceleration and quick throttle response. While specific technical details about the powertrain were not fully disclosed, the F77 was expected to be a high-performance machine, delivering impressive power and speed for an electric motorcycle.

Performance: The F77 was expected to offer impressive performance figures, with early projections suggesting a top speed of around 150 km/h (approximately 93 mph) and a rapid acceleration rate. The electric powertrain was engineered to deliver peak performance without any tailpipe emissions, contributing to a greener and more sustainable riding experience.

Battery and Range: Ultraviolette equipped the F77 with a sizeable lithium-ion battery pack, providing a decent range on a single charge. The exact battery capacity and range varied based on the riding conditions and the chosen riding mode. The company offered multiple riding modes, such as Eco, Sport, and Insane, each offering different performance characteristics and range levels.

Charging: The F77 supported fast charging capabilities, allowing riders to charge the battery to a significant percentage in a short amount of time. Ultraviolette also planned to set up its charging infrastructure in key cities, making it convenient for F77 owners to charge their motorcycles easily.

Technology and Connectivity: As a high-tech electric motorcycle, the Ultraviolette F77 was equipped with advanced features and smart connectivity. It featured a fully digital instrument cluster that provided essential information such as speed, range, battery status, and riding mode. Riders could also access additional features through a dedicated mobile app, which might include real-time vehicle diagnostics, over-the-air updates, and ride telemetry data.

Riding Dynamics: Ultraviolette designed the F77 to offer exceptional riding dynamics, featuring a lightweight yet robust frame and chassis. The bike's suspension system and braking components were expected to be of high quality to ensure a smooth and safe ride, even at high speeds.

Market and Availability: At the time of my last update in September 2021, Ultraviolette had unveiled the F77 as a pre-production prototype, generating significant interest in the Indian automotive community. However, the motorcycle was yet to undergo final testing and homologation before its commercial launch. As with any product under development, timelines and features may be subject to change, and it's essential to refer to the latest information from Ultraviolette Automotive for the most up-to-date details regarding the Ultraviolette F77.
