They are an ecologically desirable mean of transportation for every- day use. Compared with a normal bicycle, velomobiles provide a higher security standard and offer the advantages of a reduced aerodynamically drag. The European Velomobile Seminar was initiated by Carl Georg Rasmussen in 1993. The main topics of the recent seminars were design, security, transport and power assisted velomobiles. The subject of the 5th European Velomobile Seminar is: “Towards Commercial Velomobiles”. The aim of this seminar is to denominate the factors that hinder further broadening of the -
