Curaçao is amazing to explore by bike. The best choice is a mountain bike, as it allows you to reach the most beautiful spots on the island using spectacular off road trails that regular tourists or the public don't normally have access to.
Lions Dive & Beach Resort and Chogogo do have mountainbikes avalible for their guests. Both resorts are beautifully located near the saltpans of Jan Thiel.
WannaBike offers the opportunity to rent a bike after joining a tour with them, depending on avalibility.
If you want to be sure to have a mountainbike when on Curaçao and you don't want to bring your own, it is recommended to make reservations.
ROADBIKES At Viprides Curacao you can rent roadbikes. Some cyclingclubs do have an extra bike if you want to join them. If you want to bring your own bike contact your airline for conditions. You're most welcome to join the local clubs, check days and times at the "train with locals" page.
