Ultraviolet F77 motorcycle, the very first electric sports bike made in India to be tested in public.

The Ultraviolette F77 is only one of the several electric motorcycles affected by the COVID-19 pandemic that had its market launch.

Yet 2021 looks like the year we’re going to see India’s first electric sports bike move into customers’ garages.

Narayan Subramaniam, founder and CEO of Ultraviolette, took the bike on a 75 km (46 miles) route from the Bengaluru head office to Nandi Hills, preceded by another 10 km (6 miles) of hilly riding after arriving at his target. It’s the first time we have checked the relatively uncommon electric motorcycle in great detail.

The elegantly built F77 is seen supporting a pillion rider and carrying a pair of additional payload hard cases, showcasing its ability to climb hills even when loaded down.

Following other mid-sized electric motorcycles like the Zero FXS, the Ultraviolette F77 is supposed to compete against 250cc gas motorcycles, sporting drivetrain components, and performance.

The F77 incorporates a 25 kW (34 hp) engine estimated to have a 3.0-second acceleration time of 0-60 km/h (0-37 mph). The group believes the bike would provide the chain-driven rear wheel with 450 Nm (330 lb-ft) of torque, which would position it well ahead of equally driven gas motorcycles.

The F77 also features a charging port for CCS, indicating it should be capable of DC Fast Loading.

There is no news yet whether the Ultraviolet F77 is ever going to be shipped outside India. Other common Indian-made electronic two-wheelers are still struggling to fulfill domestic demand before global distribution can ever be contemplated. In India, motorcycles and scooters are incredibly prevalent, and the local market has been receptive to shifting tides towards electrification.

But there will be plenty of international interest for the bike if the F77 will achieve these performance and price goals.
