PROBLEM TO BE SOLVED: To provide a one-point pivot type bicycle with a rear suspension which is suitable for downhill and can prevent kickback when traveling on an uneven road surface.SOLUTION: A bicycle with a rear suspension comprises: a driving-side rotary member 7 mounted rotatably to a frame of the bicycle; cranks 8 which are connected to both ends of a rotary shaft of the driving-side rotary member 7 and rotated integrally with the driving-side rotary member and in which pedals are attached to the tips; a swing arm 10 mounted swingably to the frame through a suspension pivot 9; and a driven-side rotary member 12a mounted rotatably to the swing arm 10 for rotating a rear wheel 11. An endless member 15 which transfers a driving force of the driving-side rotary member 7 to the rear wheel 11 through the driven-side rotary member 12a is wound around the driving-side rotary member 7, driven-side rotary member 12a, and a second driven-side rotary member 12b rotating coaxially with the suspension pivot 9. |
