A stepless transmission comprises a driving disc, a driven disc, a first installation shaft, a second installation shaft, a first sliding block set, a second sliding block set, a first axial force application component, a second axial force application component, a triggering connecting rod, a first elastic piece, a second elastic piece and a transmission belt. When the first axial force application component and the second axial force application component axially move in the opposite directions, the first sliding block set and the second sliding block set radially move oppositely, the transmission belt is driven to move, uniform and continuous changes are formed through the radius of a rotating disc composed of the first sliding block set and the second sliding block set so as to generate different radius ratios, and therefore stepless transmission is formed. The stepless transmission is simple in structure, small and exquisite in size and stable and reliable in working. The invention further discloses a bicycle applying the stepless transmission. A gear shifting device of the bicycle is high in sensitivity, stepless transmission can be easily carried out, the best transmission speed ratio can be kept all the time in the riding process, and the phenomena of gear shifting delay and power transmission power-off are avoided.
