| description | PROBLEM TO BE SOLVED: To provide a bicycle drive crank pedal angle advancing device capable of reducing the invalid labor in the vicinity of a top dead center of a pedal when a bicycle travels, and having the function for enjoying the efficient and comfortable cycling. SOLUTION: The bicycle drive crank pedal angle advancing device makes the angle advance of the top dead center of a pedal by dividing a crank shaft into right and left portions 5, 6, and connecting them to offset gears 7B, 7C on a coupling shaft 8, and offset gears 7A, 7D on the crank shafts 5A, 5B.
