A jet powered bike will be tested at Pendine Sands in Carmarthenshire this weekend and it may break British records.
Jet Reaction uses an adapted helicopter engine to power it to a possible 450 mph.
It will be driven by Richard Brown, an Oxfordshire based engineer, who conceived and built the vehicle.
A bid for the two-wheeled land speed record will be attempted at Bonneville Salt Flats, Utah, in America in September.
