At the opening ceremony the princess spoke of the need to expand the use of bicycle transport as part of the fight against climate change. She visited the Drag Bicycles stand, where guests and the general public could test drive some of the brand’s most popular models. Drag’s flagship road bike – Drag Bluebird – attracted the most attention with its sleek new black and red kit-out. Later in the afternoon the princess took a bike tour around Sofia on one of the custom-built city bikes that Drag produced for the Embassy of the Netherlands in Bulgaria.
