A bicycle cooperative ("bike co-op") can take the many forms of the cooperative model. These often include co-ops composed of businesses to achieve economies of scale (Retail cooperative), co-ops managed by those who work at the business (Worker cooperative), and bicycle co-ops owned and managed by the cyclists that use their services (Consumers' co-operative). To date, many bicycle co-ops have taken the form of community bike shops and cooperatives organized to give the Local bike shop national scale and buying power.
