The gondola also takes bicycles (the trip up the mountain costs €18, including the bike, May 2024). Departures are every half hour. At the summit, you can't immediately hop on your bike and race down; you still have to push your bike up a few dozen rather strenuous meters to the summit (it was too steep for me to ride up). But that's done in half an hour. There's a hut at the top where you can get some caffeine (or something else).
