Source Two SE

Part No.  
With a bicycle, the world gets smaller. In Africa, it allows HIV caregivers to visit five times as many clients in a day. Here in the West, it breaks isolation and connects us to the city's energy. The Source Two LTD is the ultimate bike for staying connected to your community, and through a partnership with Gates and SRAM, it's also the best way to help caregivers in Kenya stay connected to theirs. For every Source Two LTD sold, we'll donate a specifically-designed bike to World Bicycle Relief so that caregivers like Fred here can continue to fight, and defeat HIV in Africa.
