Whether you're zipping through city streets or taking it for a spin on winding back roads, the BT-50 promises fun and excitement at every turn.

At the heart of the BT-50 lies a robust 49cc single-cylinder, two-stroke engine that delivers a peppy 5.48 horsepower at 6500 RPM. This spirited powerplant propels the bike to a top speed of 85 km/h (52.8 mph), ensuring that every ride is a thrilling adventure.

The Tomos BT-50 is equipped with a sturdy steel tube frame that provides durability without sacrificing weight. Its suspension is designed for nimbleness, paired with a single disc front brake and an expanding drum brake in the rear for reliable stopping power. The inclusion of a digital Ignition system by Iskra enhances engine reliability and performance, while the Bing 17mm carburetor ensures that the engine breathes efficiently. With a fuel tank capacity of 11.50 liters (3.04 gallons), the BT-50 allows riders to enjoy longer rides before the need to refuel arises, making it a practical companion for those who love the open road.
