Muybici company offers a service of sustainable mobility at Murcia by managing the rental bikes at the urban area. At the inicial phase, the company set 400 bikes through the city. The peripheral design of the service, bikes and stations was inspired in a implemented model at European cities, but, in an early stage, an enormous quantity of vandalic acts took place, which influenced on the company and the municipal administration. To confront this situation, IDEA decides to offer their service to Muybici in order to create a solution against those incidents. With that goal, we made an analysis of the problem to create a solution that respects the current experience of use created by Muybici.
