Manufacturing/building method(s)Detail regarding solution production or construction method (instructions, mass production capacity, custom made,etc...)

The Bici Desgranadora is made from bicycle received as donation from the US and Canada, bicycles that cannot be reconditioned are dismantled with certain parts (pedals, bicycle frames, etc) used in designing the pedal powered bicycle corn thresher. Materials are sourced locally and incorporated in the building of the equipment. The metal frame for example is welded together to the other engineered parts like the seats which is made from plywood. The flywheel is made by adding cement to the mould of the wheel. The equipment can be ordered and made to specification of the client, thus the building methods arehalf artisanal and half industrial.

Design specificationsComponent and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The product is stationary and pedal powered, it requires no electricity to be operated. It is made from used bicycle parts such as pedals, frame, chains and handles. The pedaling system is connected to a cement flywheel to facilitate continuous pedaling and uses sprockets’ diameter relation to vary speed and torque. The system is connected to a corn sheller in a position where the same person pedaling can feed it.^{Interview with representative in 2018}
