We see more and more bicycles daily on the streets of Madrid. To celebrate this bicycle renaissance the 'FestiBal with B for Bike' is back for its fourth edition in Matadero Madrid. The whole day (from 11am to 10pm) there will be dozens of activities for all ages – a slow race, street BMX, exhibitions, acrobatics, classes on riding tandem, bicycle workshops, and chalk and handlebar decorations for the little ones. There will also be concerts for the whole family and a picnic with breakfast, lunch and afternoon snacks made with organic products. And it's all free!
