I rented a roadbike for a couple days. It's the perfect way to challenge the mountains of Malaga. Leave the town in northern parts and climb the mountains for a beautiful view over the city and the rest of South-Andalucia. Silent roads in protected nature parks. Sometimes you see a car or other biker, but most of the time you're alone with the mountains. It's fantastic.
Bike2Malaga gave me a good bike and other goods like a helmet, spare-tube, mini-pump and SPD-pedals. You only need your own legs to have a great time!
