The Macchi MB1, also called Macchitre[1] (due to its three wheels),[2] is a three-wheeled truck, designed by Ermanno Bazzocchi[3][4] and produced starting from 1945 by the Italian company Aermacchi for the sector road transport.

The vehicle is also known under the Bremach brand: a Bremach motorcycle after the Varese-based company, which then moved to the province of Brescia, acquired the production rights towards the end of the sixties.
