The Wiltshire charity Jole Rider says the bikes are refurbished and reused by Gambian youngsters, who often face a 10-mile walk to school.
The Bikes 4 Africa project will load more than 330 bikes on a sea container at next weekend's Brinkworth Show.
Donors are asked to bring along their unwanted machine together with a £10 shipping cost fee if possible.
David Swettenham, from the Sherston-based charity, said what began as a plan to hold a special fund-raising bike ride turned into a major project.
"We had this crazy idea of doing John O'Groats to Lands End," he said. "We've not done it yet - I suppose you could call this a diversion."
"Then we found out that the bikes would be useful and it went on from there."
Bikes are also collected from recycling centres around Wiltshire.
Those going out from the Brinkworth Show next Sunday will go to three secondary schools in Gambia.
When a student finishes his or her education, their bike remains at the school to be used by another student.
