See Lisbon on brand-new e-bikes, tailor-made for the hilly city. Enjoy the universal fun of riding a bicycle, with the electric engine giving you a push on the hardest parts of the way.  See Belém, known as the historic district of the Age of Discovery and the sensational architecture of the Tower of Belem and Jerónimos Monastery (both World Heritage Sites). This is also Lisbon's museum district, with the one-of-a-kind Coaches Museum filled with royal fairy-tale vehicles, the Berardo Museum showcasing a world-class collection of international contemporary and modern art, and the iconic MAAT.  Despite all these attractions, it's a pastry shop that receives the most visitors. At Antiga Confeitaria de Belém. you may devour one or several of Lisbon's famous custard tarts that originated on this site, and that are still unlike any others found around the country, made here from a secret recipe.
