Cyclekart Introduction

Cyclekarts are compact, lightweight, sports machines, home and hand made by their drivers for the pursuit of classic motoring sporting excitement. They're not built to be serious race machines or show cars. They're built purely for the personal satisfaction and fun and of driving a machine you've built yourself. As driving machine, the CycleKart formula loosely limits certain aspects of the machines to maintain good sporting performance without jeopardising the light-hearted nature of these machines and the people who build them.

CycleKarts and their builders don't like to take things too seriously, but do encourage good, sporting competitions for fun. The Cyclekart specifications allow for all the cars built being similar in performance, without strictly governing the rules.

Cyclekarts are generally not for sale, as they should be an expression of the owner's individual styling interests as well as sharing the pride in building one's own unique kart. Cyclekarts are built for the pleasure of the imagination, the design and the building of the kart. Cyclekats are based on the styling of 1920s and 1930s race cars to pre WWII. Making it look good is fundamental, performance is secondary in the Cyclekarting community.

Please read the CycleKart Frequently Asked Questions (FAQ) for more information.
