World Bicycle Relief combines bicycle donations with a social enterprise model. Sales by its Buffalo Bicycles subsidiary support its programmes, while local assembly, shops and mechanic training help keep bicycles in use.
Buffalo bicycles are designed for daily travel on rough rural roads and carrying heavy loads. Their construction uses readily repairable components.
In 2025, the organisation distributed 96,630 Buffalo bicycles. In Colombia, Buffalo Academy trained 2,793 students in bicycle maintenance. That year also brought mobile repair clinics and retail outlets, with mechanics taking on spare-parts sales. This approach connects access to bicycles with the skills needed to keep using them.
