An adjustable pedal system for changing the position of pedals along the crank arms of an exercise bike. The system provides a locking member, such as a rack, located along the crank arm and a locking member, such as one or more gear teeth formed on a slide sleeve to which the pedal is affixed. Thus the slide sleeve and pedal can be slid along the crank arm to the desired position whereupon the locking members intermesh to positively lock the pedal in the desired location. The intermeshing is maintained by a clamping device, such as a thumb screw that is tightened to lock the pedals in the desired location and loosened to disengage the locking members to allow the movement of the pedals to another location. The system can be operated without the need for tools and can be retrofitted to existing exercise bikes.
An exercise bike having a system to adjust the location of pedals along a crank arm, the exercise bike comprising a frame, a crank mechanism mounted to the frame and having a main shaft rotatable about an axis of rotation and a pair of crank arms extending outwardly from the main shaft, each of the crank arms having at least one locking members formed along each crank arm, a pair of slide sleeves having a pedal affixed thereto, each of the slide sleeves being movably affixed to one of the crank arms, the slide sleeves having at least one locking member formed thereon therefrom adapted to intermesh with the at least one of the locking members on the crank arms to retain the pedals at desired locations along each crank arm and a clamping device to releasable maintain the locking members of the crank arms and the locking members of the slide sleeves intermeshed together.
The exercise bike of claim 6 further including a window formed in the slide sleeve through which the linear scale can be viewed.
