At S-Bikes they love cycling and they know the business. You get a bike, all the necessary stuff, and a map of interesting and challenging routes and places to visit, MTB or road. Be sure to write in advance in case you need something specific or if you want a group tour.
Northern Corfu is a great place for cycling and S-Bikes provides everything you’d need for it. Also, the Bike Cafe has perhaps the best choice of beer.
