Pure driving pleasure. Pure joy.

More than ever, mobility determines our everyday lives, be it in the professional, business or private spheres of life. The type of mobility is up to each individual, who takes into account economic and ecological factors as well as the desire for a better quality of life. That's why we have developed a roadster that guarantees the highest degree of exclusivity through one-off production and thus a high level of value retention, that features the latest technology and, above all, conveys pure driving pleasure – the BOLDMEN CR 4 / CR 4 S.

In times of uniformity in the streetscape, there is now a sports car that pleasantly sets itself apart from industrial mass production and with which the driver expresses his or her personality. Individual production according to the individual wishes of the buyer also means that each roadster is unmistakably unique.

A bold, independent design meets maximum agility and dynamism. The CARBON body is not only lighter, it also guarantees perfect clearances, optimum surface quality and resistance to all environmental influences, which ensures durability. We are convinced that it is never just about getting from A to B, but also about a better quality of life through pure driving pleasure.

Welcome to BOLDMEN.
