featured the Jawa 350 type 572 - 04 engine. Problems in design and manufacturing, as well as the inability to compete with higher-category cars (including the cheap Trabants), made the four-wheeler a commercial failure, and its production was stopped in 1973. Plans to produce a small car similar to Fiat 500 or a rickshaw-like truck did not materialize. Spare parts for Velorex vehicles were first produced in the Solnice plant, and then in Rychnov nad Kněžnou after 1975. In the mid-1980s, India tried to obtain a license to produce the three-wheelers; the deal failed because the original tooling no longer existed. Statistics About half of the production was exported to Eastern Bloc countries (Hungary, Poland, Bulgaria, East Germany) - 7,540 vehicles in total. In Czechoslovakia, the demand exceeded the supply and the new cars were sold only to the disabled after thorough examination by an official commission. Part of the production was allocated to companies and organizations. As of 1996, 62.5% of the three-wheelers sold in Czechoslovakia were still registered. As of 2006 the vehicle can be still seen occasionally and it has obtained cult-like status among its owners. Several Velorex clubs exist in the Czech Republic. Rallies are regularly organized in Boskovice (last in 2007) and in Lipnice nad Sázavou, inside the Lipnice Castle. Until 2000 only the motorcycle driving license (A) was required, afterwards the B1 license (car from age of 17). Technical parameters Velorex was built on a frame of welded steel tubing, with bodywork consisting of vinyl (called "Igelit") stretched over the cage and attached by turnbutton fasteners. Like most of other three-wheeler types Velorex had two wheels in the front and one wheel at the back.
