An exercise machine has a flywheel, a rotary input member, and a clutch mechanism that is positionable in a freewheel position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member permits continued rotation of the flywheel. The clutch mechanism is alternately positionable in a direct drive position in which rotation of the rotary input member causes rotation of the flywheel and wherein thereafter ceasing rotation of the rotary input member prevents continued rotation of the flywheel. Advantageously, movement of the clutch mechanism from the freewheel position to the direct drive position is prevented when rotation of the rotary input member is out of synchronization with rotation of the flywheel.

An exercise machine has a first frame member, a second frame member that is movable with respect to the first frame member, and a locking device having at least one cam that is rotatable into and between a locked position in which the cam abuttingly engages and thereby retains the second frame member in position with respect to the first frame member and an unlocked position in which the cam is spaced from and thereby frees the second frame member for movement with respect to the first frame member. The cam has an engagement surface with a contour that follows a logarithmic spiral curve defined by the following parametric equations: x(t)=r(t)cos(t)=aecos(t), and y(t)=r(t)sin(t)=aesin(t), wherein e is the base of natural logarithms and a and b are arbitrary positive real constants.

Systems and methods are for determining and indicating a desired corrective change in exercise technique to an operator and optionally for determining and indicating a correct or incorrect fit between an operator and an exercise equipment. The systems comprise an exercise apparatus that is engaged by an operator at least a first contact location; a first load sensor device that senses an operator-applied load amount at the first contact location; a controller that determines a desired corrective change in exercise technique and/or the correct or incorrect fit between the operator and the exercise equipment based at least upon the operator-applied load amount at the first contact location and a current body weight of the operator; and an indicator device that indicates the desired corrective change in exercise technique and/or correct or incorrect fit, for example to an operator or an instructor.

A bicycle having a pair of wheels and a frame formed of two crossing bars that are detachable from each other so as to form a separate unicycle and a pedal bike, one of which includes a handle bar at a top, and the other a seat at its top, while each has one wheel at a lower end.
