One of the focused stories at Interbike was bikes for Africa. There were a number of groups represented including SRAM and their World Bicycle Relief, and Tom Ritchey and his Project Rwanda<a/>. There is plenty of good literature on the sites, but if you can help – you can donate here or here.
[UPDATE – Another local group is sending bikes as well:]
The Village Bicycle Project provides sustainable and affordable transportation for Africans. Owning a bike promotes poverty reduction, rural development and personal empowerment. Millions of Africans do not have basic, reliable transportation. 99% of Africans cannot afford cars. Public transportation is expensive and unreliable. Contact email@example.com if you can help.
