In 1920 Mr. Gabriel Trejo started in the craft of blacksmithing, repairing wheels, axles and hinges from his father's diligence; from that moment the passion to transform steel came to him. Blacksmithing was the craft which Mr. Gabriel dedicated his entire life and over the years transmitted his knowledge to his successors.

When the first cars arrived to Zacatlan Mr. Gabriel learned how to repair the cars mechanisms, this triggered his creativity and inventiveness making him able to create any type of mechanical instrument such as farm machinery, canning food machines, equipment for the manufacture of footwear and more. Some of these machines were powered by gasoline engines adapted from old cars, because there was limited electricity in Zacatlan.

In 1950, Don Gabriel created with the help of his son Abraham a gun; this was unlike any other around. This was the "Trejo 22 tipo rafaga". Currently, the gun is recognized by specialized collectors as unique piece , the gun had the mechanism to either perform gun shots one by one or a burst like a machine gun, for this reason, many experts call it the world's smallest machine gun. This invention leaded to the foundation in 1958 of the weapon factory "Armas Trejo S.A. de C.V." to which the second Trejo generation would be integrated, Mr. Gabriel Sons: Gabriel, Abraham, Lucio and Angel Trejo Solis.

In the year 1971 by presidential decree were closed four existing weapons factories in Mexico as a result of social problems that were experienced between 1968 and 1971.

Given the closure of the company, by 1972 was founded "Trejo Industrial S.A. de C.V." manufacturing agricultural machinery and equipment for the food industry. Later on in 1973 it began manufacturing brakes and handlebars for bicycles tourism type.

In 1979 Mr. Angel Trejo Solis acquires the 100% of the shares of Trejo Industrial S.A. de C.V. and together with his sons founded "Manufacturas Trejo S.A. de C.V.", so the third generation of family Trejo joins the task of transforming metal.

As a result of multinational agreements for trade liberalization, duty-free importation of products manufactured by the company was stared, forcing the company to look for other products; starting in 1994 the manufacturing of cargo bicycles, product manufactured to date.

Between 1998 and 2001 takes place wrought iron and wood furniture manufacturing, which was exported to United States of America and Europe; products that were no longer manufactured once Chinese furniture products flooded those markets.

Currently cargo bikes manufactured by Manufacturas Trejo S.A. de C.V. are exported to Panama, Guatemala, Cuba, Belize, Italy and United States of America.

Today has already integrated the fourth generation of the family Trejo to the company’s activities, with a mission to honor the legacy of quality, creativity, innovation, honesty and work.
