With this, you can rent a decent city bike for just €3,15 per day at bike points located in or near 44 Belgian stations, including Brussels North, Brussels Central, Brussels Luxembourg and Brussels South.

What’s the difference with Villo?
1. It’s everywhere in Belgium, not only in Brussels.
2. Users: Blue-bikes are aimed at local and international travelers who regularly or occasionally need a bicycle in and around Belgian cities.
3. Rental period: a Blue-bike subscriber can use the bicycle all day long. You don’t ride from A to B, but from A to A; your point of departure from which you will likely take a train back.
