Patent ID: 8409060

Claim:
An exercise bike, comprising: a frame; a first exercise module, which is connected to the frame, including a main axle, a driving wheel mounted on the main wheel, and a forward one-way clutch between the main axle and the driving wheel, wherein the main axle is driven to rotate in a forward direction and a backward direction that the driving wheel is driven to rotate in the forward direction through the forward one-way clutch when the main axle rotates in the forward direction; a second exercise module, which is connected to the frame, including a main axle, a driving wheel mounted on the main wheel, and a forward one-way clutch between the main axle and the driving wheel, wherein the main axle is driven to rotate in a forward direction and a backward direction that the driving wheel is driven to rotate in the forward direction through the forward one-way clutch when the main axle rotates in the forward direction; and a damping device having a driven wheel connected to the frame, wherein the driving wheel of the first exercise module and the driving wheel of the second exercise module are connected to the driven wheel respectively for driving the driven wheel to rotate; wherein the first exercise module further includes a transmission gear mounted on the main axle, a backward one-way clutch between the main axle and the transmission gear that the transmission gear is driven to rotate in the backward direction through the backward one-way clutch when the main axle rotates in the backward direction, and a turning gear meshed with the transmission gear to rotate the driving wheel; and wherein the second exercise module further includes a transmission gear mounted on the main axle, a backward one-way clutch between the main axle and the transmission gear that the transmission gear is driven to rotate in the backward direction through the backward one-way clutch when the main axle rotates in the backward direction, and a turning gear meshed with the transmission to rotate the driving wheel.
