Each leg of the first pair of legs extending at an oblique angle from the lower frame member in a deployed position configured to support the folding exercise bike on a surface and each leg of the second pair of legs extending from lower frame member at an oblique angle in the deployed position.

A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

A fitness pull device includes a torque-controllable motor and a pull mechanism. The pull mechanism includes a housing which covers the motor, a motor base fixed in an inner cavity of the housing, a winding piece rotatably connected to an output shaft of the motor, and a rope wound on the winding piece. The motor transfers torque required by a user to the rope on the winding piece, so that the size of the force is changed according to the actual usage requirements of the user. The motor acts as a force generation apparatus, and the controllability of the existing torque of the motor is used in combination with the pull device structure such that the size of the force can be changed according to the actual usage requirements of the user, in order to enrich the user fitness experience, and achieve a better effect.

An exercise device includes a frame and an exercise deck. The exercise deck includes a platform, a first pulley connected to a front portion of the platform, a second pulley connected to a rear portion of the platform, and a tread belt surrounding the first pulley and the second pulley. The exercise device also includes a motor in mechanical communication with at least one of the first pulley and the second pulley to drive the tread belt and an energy efficiency indicator that actives in response to determining that a power load needed to operate the exercise device is below a predetermined energy efficient threshold during a performance of an exercise.

A folding exercise bike can be easily assembled and disassembled/folded for storage and/or transportation. The exercise bike can include a telescoping seat, a telescoping stem, a fold to stow handlebar and fold down locking legs. Various configurations for the exercise bike can be used. The exercise bike can include a wireless transmitter to transmit cycling data to a user's portable electronic device.

The present invention discloses a cycling or motorcycling simulator for recreation and physical exercise characterized by allowing left, right, and backward movements and tilts that can be controlled with the handlebars or body thrust. Structurally, the device of the present invention is divided mainly into six parts interconnected to get the device to function optimally. Thus, the simulator consists of i) a base that supports the other systems of the invention, ii) a mounting base that allows coupling the lifting system, the lower coupling system, and the lateral tilt system, iii) a frame giving a bicycle-shaped structure to the simulator, iv) a lifting system, v) a lateral tilt system, and vi) a lower coupling system; wherein the said systems control the turns and the tilt of the simulator. Because the present invention allows a greater range and variety of movements, the monotony of the exercise is reduced, and the user can exercise a greater number of muscles.
