All our holiday homes in Zell am See and Kaprun have separate bike storage in the bottom for our guests' bicycles. Most of them are for shared use, but definitely lockable for unwanted access from outside. With many we have also water access outside to house to wash your rental bike for the next day's tour.
Our holiday flats have even power sockets or charging points in the bike cellar. Our partner in bike rental Zell am See will be happy to advise our guests on charging times and the ideal use of batteries for machine and biker.
