An effort-saving bicycle is provided. The bicycle includes at least one wheel. The wheel is centrality provided with a shaft gear at its rim. The shaft gear is connected to a chain that is further connected to a transmission gear. The transmission gear has its shaft connected to one end of a first crank whose opposite end acts as a first crank joint connected to a link's one end at its inner side. The link has its opposite end provided with a pedal. The first crank joint of the link is connected to one end of a second crank through a second crank joint whose opposite end is connected to a second crank-frame joint that is connected to a frame. The specially located transmission gear working with the extended links that connects cranks and pedals allows effort-saving bicycling based on the lever rule.
