The story
Original developments
The first chassis developed by BIAMAX was introduced in January, 1960. In the same year the famous R series of coaches and inter-city buses was introduced. One of the earliest chassisless bus designs in the world, it was an engineering achievement involving novel approaches in suspension and structure, developed by the engineers Antonios Rizos (who lent his name initial to the series) and Ioannis Dracoulis (who was responsible for its extremely elegant, streamlined design). Models R495 (inter-city bus) and R514 (coach) became common sights in the country, establishing the BIAMAX brand. In 1962 a trolleybus type (also chassisless) was designed and built, with Lancia axles and transmission and CGE electricals; as an imported type was ordered for Athens, only one trolleybus was produced but it nonetheless entered service remaining in operation for more than 15 years.
1960s and 1970s: The "Golden Age"
The very successful F series of city and inter-city buses (named after Fostiropoulos initial, a designation used earlier as well) was introduced in 1965 employing a ladder-type chassis developed by BIAMAX, and, as most of its products, Mercedes-Benz engines. The most common types produced were the F530 and F580, with several body variations for a variety of end uses. At the same time BIAMAX introduced railway wagons, and kept producing an extended range of bus and truck bodies, assembling 4x4's and tractors etc., with thousands of vehicles coming out of its factories, many of which were exported to a large number of countries, mainly in Europe, Asia and Africa; at times the company exported as much as 50% of its production. One of the most notable models specifically developed for Africa and the Middle East was the "Desert Bus", an extremely rugged construction whose production started in 1963, for long-distance travel with cross-country and extra load capabilities (including the capability to carry tons of load on its roof), optionally with A/C, beds, toilets etc. F580 types can be seen to this date working hard in the Middle East. Indeed, the legendary reliability of BIAMAX buses can be testified by the large number of surviving examples, most of them in excellent working condition. One of the most successful ventures of Biamax was the production of Mercedes-Benz O302 and O303 coaches, including variants like the O302S2 type, which essentially was a "blend" of both models.
