Maya Pedal puts old bike parts to productive use, transforming them into machines that create livelihoods in Guatemala

— Bicimaquinas

02. Mobility Dispatches

The morning hours at Maya Pedal were filled with the sounds of grinding metal for the bicicuchilladora, a bicycle-powered cutting machine. The simple appliance, powered by a bicycle drivetrain, has at its heart a concrete cylinder, with columns of two-inch-long blades spinning within a plastic tube. Once used to move people, its bicycle parts now mince plastic in preparation for recycling or turning compost.

Maya Pedal co-founder Carlos Marroquin mastered the feat of connecting bicycle drivetrains to new mechanisms long ago. His organization, established in 1997, has created at least 16 different kinds of pedal-powered machines, or bicimaquinas, using recycled bikes and parts, perennially improving their designs to be more useful and affordable for farmers.

The challenge of constructing the bicicuchilladora belonged to Victor, a teenager hired by Carlos. It was Victor’s responsibility to fashion by hand each of the nearly two dozen blades at the heart of the machine. The process is not the most efficient, but Victor values the craft itself and its impact on the community.

The bicimaquinas make a tangible difference for campesino villagers. The bike frames, handlebars, and drivetrains conserve time, money, and labor for farmers across the region. The bicimolino corn mill and bicilavadora washing machine save energy—both physical and fossil—for women who once completed these tasks by hand every day. Hand-powered alternatives demand time and effort, and the cost of fuel puts gas-powered ones out of reach for most.

The bicibomba water pump has the same benefits. Still, it can run as high as USD 300—nearly a month’s income for the average rural Guatemalan—and can thus require collective ownership, financing mechanisms, or otherwise a convincing return on investment. This price results largely from the labor invested by workers at Maya Pedal. The machines themselves are made from the refuse of bicycles: chains, gears, cranks, and handlebars, combined with common scrap metal and plastic.


Maya Pedal’s contraptions include corn mills, cutting machines, and blenders—all produced from scrap parts at its shop in San Andrés Itzapa, Guatemala.

The underlying genius of the bicimaquinas lies not in their function or even the customization of their parts, but in Maya Pedal’s vision for using the raw bike parts as a medium for connecting people locally and globally.

Maya Pedal espouses the idea of building social capital—the value emerging from the relationships between people. This differs from physical or human capital in that it is about intangible connections—social networks derived from norms of reciprocity and trustworthiness, to paraphrase sociologist Robert Putnam. While the bicimaquinas serve villagers in achieving their specific purpose—grinding corn, pumping water, or washing clothes—it is the collaborative innovation among engineers in San Andres Itzapa and their North American partners which has bred a sustainable solution with promise for rural communities worldwide.

Maya Pedal was founded in the wake of the Guatemalan Civil War, when volunteers from PEDAL, a Vancouver-based organization dedicated to bicycle-powered development, partnered with Guatemalan leaders to hatch the idea of a shop dedicated to bicimaquinas. Fueled through the years by the donation of thousands of bicycles from the Massachusetts-based Bike Not Bombs, Maya Pedal has been able to fashion the simple machines called for by everyday Guatemalan life. Without this bridge, the fabrication would not be possible.

Maya Pedal’s form of partnership combines a sustainable local business model with experts abroad who donate their skills in bicycle maintenance, small business development, and marketing. All staff and volunteers are encouraged to provide feedback about the design of the machines, the layout of the shop, or the effectiveness of the business model. This feedback loop strengthens future design: engaged helpers can stay as long as they want, offering continual input as they hone their engineering and building skills.

Bicimaquinas3The bicilicuadora blender has emerged as perhaps the most ubiquitous design. The bicilicuadora affords its users the ability to create a host of essential food products, adding value to their produce that might otherwise be done by food processors in cities or abroad, leaving little profit for the farmers at the front end of the supply chain.

The biclicuadora’s ubiquity arises not just from its utility, but also from its elegant simplicity. The rear wheel of a standard bicycle is lifted off the ground by a specialized stand, so a user can comfortably pedal the bicycle in a fixed spot. A small turbine drags against the rear wheel, propelling a wire that runs all the way to a wooden tray affixed to the handlebars. On this tray is a blender, and the wire is connected to the underside of its blades. This design was honed over time through the collective input of those who have come through Maya Pedal’s shop.

Meanwhile, Victor’s newly minted cutting machine whirs away—minced plastic radiating out from the central cylinder, each bit representing an opportunity for income. Positioned at the center of its own ecosystem, Maya Pedal keeps spinning its wheels, charting the paths among people, places, and machines toward the development of Guatemala.
