Built with rough terrain in mind, the Stealth F-37 is lightweight, nimble and tough. NB: Stealth Bikes are NOT street legal.


The F-37 continues Stealth’s reputation for manufacturing ebikes built with rough terrain in mind. The lightweight, nimble frame is constructed from some of the world’s toughest aerospace materials, enabling the F-37 to handle tight tracks easily and reach speeds of up to 60km/h. Combine this with a fully adjustable suspension, 2 speeds for pedalling and a 3.5kW direct drive hub motor and it’s easy to see why the F-37 is a popular choice. NB: Stealth Bikes are NOT street legal.
