For this you need mountains and valley. The mountain and best of all with funiculars to avoid boring uphills, for great trails for downhill and the valley with easy but not boring bike paths for the whole family. This combination can be found in a perfect manner in the Drei Zinnen-Dolomites region with great Mtb possibilities and the cycle paths Innichen-Lienz and Innichen-Bruneck and back by train or San Candido-Cortina d'Ampezzo - more info on the homepage of Berghotel Sesto www.berghotel.com
