Maya Pedal is an NGO been born in 1997, with the aim to help the development of the rural communities in Guatemala, through the utilization of the “bicimaquinas”. With the term bicimaquina (bicycle machine) they refer to an intermediate technology, developed from recycled bicycles: therefore it’s a self-sufficient and eco-sustainable technology, as it does not demand electric power or fuel for its operation; moreover it’s a reliable instrument of support for the familiar economy, as the machines produced have always an immediate functionality. In the workshop of San Andres Itzapa (Chimaltenango, Guatemala), thanks also to the contribution of a group of researchers of the MIT (Massachusetts Institute of Technology) of Boston, various types of bicimaquinas are designed and assembled, just as an example: bicycle blenders (bicilicuadoras), bicycle soil mills (bicimolinos), bicycle corn degrainer and coffee depulper (bicidesgranadora de maiz e bicidespulpadora de cafe), water pumps (bicibombas de lazo), washing machines (bicilavadoras), tricycles and bicitaxis, bicycle plows (biciarados) and bicycle electricity generator (bicigenerador de electricidad). Collaborating directly with the fantastic people who create the small staff of the organization, I have been able to understand how much is appreciated in Guatemala and above all in the rural communities the activity of Maya Pedal: every day new interested people and associations come to visit the workshop or contact them, in order to buy and distribute the assembled machines on the territory. It’s so interesting to participate to the simple but brilliant production process of every bicimaquina, which is exclusively based on the utilization of parts of used bicycles, opportunely modified. This article aims to be a suggestion for all who want to get involved in a volunteering project that in concrete terms acts on the territory, carrying benefit to the Guatemalan rural communities, where still lack basic services. The web sites of Maya Pedal and Pedal Power provide a good source of information for anyone interested in the project.
