significant impact through. their interaction with the chronically ill. Among the quantitative outcomes of this program is the finding that since World Bicycle Relief's participation in RAPIDS, caregiver retention has risen to 97%, a marked increase from earlier stages. World Bicycle Relief also trained over 470 mechanics. A key element of this program is the "culturally appropriate" bicycle, specially designed to meet the needs of the local populations and to withstand the African terrain. The single-speed bike, weighing in at , is equipped with a heavy-duty rack capable of transporting , automotive-grade nylon ply tires, coaster brakes, reinforced spokes, and a frame constructed of higher-gauge steel tubing. Project CHAI World Bicycle Relief, in support of CHAI (Clinton Foundation HIV/AIDS Initiative), provided 300 bicycles to people across Rwanda, Kenya, Ethiopia, Mozambique, Tanzania, and Lesotho to help specific HIV/AIDS initiatives in Africa. The bicycles were provided to healthcare workers addressing the medical needs of people living with HIV/AIDS, mentors working with orphans and vulnerable children, and educators teaching disease prevention. Disaster Relief In partnership with World Vision, Trek Bicycle and local government, World Bicycle Relief provided 24,3676 bicycles in Sri Lanka to men, women and children in greatest need following the 2004 Indian Ocean tsunami. The selection process included basic economic and commercial needs, distance to work, and distance to schools. An independent report found that nearly 90% of the bike recipients used their bicycles to earn a livelihood. World Bicycle Relief has also provided bicycles to relief organizations working in Kenya to combat the 2011 famine in the Horn of Africa. Microfinance and Social Enterprise Initiatives World Bicycle Relief has also partnered with a variety of microfinance institutions to allow the sale of the WBR bike (The commercial version of their specially designed bike is called the "Buffalo Bike".) to individuals who cannot afford to purchase the bicycle in a one-time transaction. One example of their microfinance work can be seen at the Magoye Milk Co-operative, a small organization of Zambian dairy farmers established by Land O'Lakes, Inc. Here, 299 farmers use Buffalo Bicycles purchased from World Bicycle Relief to transport their dairy to the central depot, where the milk is collected and transported to a dairy processing factory. The acquisition of these bicycles has allowed the farmers to increase their carrying potential while reducing the time (crucial when transporting milk) and money farmers need to spend on delivering their product
