Abstract
This exercise bicycle includes a frame having a front fork portion supporting a pair of handlebars and mounting a rotatable wheel; a rear ground-engaging support portion, and an intermediate portion supporting the seat and mounting a pedal sprocket. A coin-operated drive resistance assembly is mounted to the rear of the frame, the assembly including a shaft having a sprocket connected thereto by a torque limiter device which sprocket is drivenly connected to the pedal sprocket and the front wheel; a disc brake on the shaft and a hand control for setting the brake for predetermining the resistance of the shaft to rotation; a lock for the shaft including a member rotatable with the shaft, and a coin-operated timer switch for actuating a solenoid to deactivate the lock for unlocking the shaft, the unlocked period being determined by the timer. The torque limiter device permits limited rotation of the sprocket on the shaft and consequently the bicycle pedal sprocket when rotation of the drive assembly shaft is abruptly terminated by the locking of the shaft at the end of the coin actuated time.
