In the difficult post-war period, Ardex experimented with various bodies and chassis designs. Along with 4-wheeled microcars, a 3-wheeled model was made in a single copy (or minimum batch). It had a simple T-shaped tubular frame and a wooden two-seater body. A single-cylinder 50-cc engine was located near the rear left wheel and powered it using a chain drive. The front wheel was steerable.
