An angle adjusting mechanism includes a first bracket and a second bracket hinged to each other. The second bracket is provided with two arc-shaped position-limiting slots, and a set of position-limiting holes is arranged in the position-limiting slots. A diameter of the position-limiting holes is larger than a slot diameter of the position-limiting slot. A bolt passes through the first bracket and the position-limiting slots and is movable along the first bracket and the position-limiting slots. An end portion of the bolt is provided with an adjusting segment and a position-limiting segment. A diameter of the adjusting segment is smaller than a diameter of the position-limiting segment. The adjusting segment and the position-limiting slot are engaged to adjust an angle of the second bracket relative to the first bracket. The position-limiting segment and the position-limiting holes are engaged to fix the first bracket and the second bracket after adjustment.

Provided is an information processing device including an acquisition unit configured to acquire first load information measured by a first load measurement device provided on a sole of a user and second load information measured by a second load measurement device provided to be closer to a toe of the sole than the first load measurement device and a determination unit configured to determine whether or not the user is in a pedaling state in which the user pedals a bicycle based on the first load information and the second load information.

A power measurement device, which may be mounted to an inside area of a crank arm, includes processing circuitry within a housing. The processing circuitry is coupled with strain gauges mounted on the crank arm, and produces a power value that is wireless transmitted to a separate display that may receive and display power measurements. The housing may include a mounted portion and a cantilever portion where the mounted portion houses the processing circuitry and the cantilever portion houses batteries supply energy for the processing circuitry and other features.

An electric magnetic resistance control structure for an exercise machine includes a base; a flywheel, pivotally connected to the base through a rotating shaft, the rotating shaft defining an axial direction, the flywheel, a non-magnetically sensitive layer being coupled to a circumference of the flywheel; a power unit, fixed to the base; a magnetic resistance unit, including a coupling portion corresponding to an arc of the non-magnetically sensitive layer, at least one magnetic member being provided on the coupling portion and kept at a distance from the non-magnetically sensitive layer to generate a magnetic resistance effect; a control unit, configured to control a current applied to the power unit to drive the magnetic resistance unit to move along the axial direction, thereby changing an overlapping area of the magnetic member and the non-magnetically sensitive layer in the axial direction, so as to adjust a magnetic resistance of the flywheel.

The present disclosure relates to an exercise device comprising a pedal assembly coupled to a braking device. The exercise device comprises a housing, through which a main transverse axle extends and which is arranged at a height of between 120 and 170 mm from the bearing surface on the ground, the main axle being coupled at either side of the housing to a disc-like plate that supports an eccentric transverse axle, the eccentric axles being orientated in a diametrically opposed manner relative to the main transverse axle, each of the eccentric axles being articulated relative to a connection piece with a pedal formed by a plate that is articulated relative to the connection piece by a pivot that is parallel with the longitudinal axis of the plate in order to allow the plate to move between a horizontal active position and a storage position in which it is folded against the vertical face of the housing, the main axle driving a flywheel received in the housing.

Disclosed is a fitness equipment provided with massage pedals, comprising a frame, two pedals, two rotating shafts, a flywheel swing arm, a flywheel, a damping wheel and a belt; the pedals are mounted on the frame and provided thereon with massage mechanisms; the pedals are connected to the rotating shafts; inner ends of the rotating shafts are rotatably connected to an outer end of the flywheel swing arm; a middle portion of the flywheel swing arm is sleeved on an outer end of a flywheel axle; the flywheel axle penetrates the flywheel, a middle portion of the flywheel axle and the damping wheel are rotatably mounted to the frame; and the belt is wound on the damping wheel and the flywheel.

A human power strengthening machine consisting of a frame, hand pedals, foot pedals and a flywheel coupled to said frame, with hand grips and foot-bindings coupled to said pedals wherein the grips and bindings allow the user to crank said pedals and drive a flywheel. There is a unit, which provides magnetic resistance to the flywheel. Also coupled to the frame can be a display with microphone for voice control of magnetic resistance to the flywheel. In this case there can be, for example, a flywheel, which is driven by the pedals, a magnetic resistance unit and display with microphone for voice control of flywheel resistance, plus non-driven casters as well.

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 modular exercise apparatus comprising a frame, a common drivetrain supported by the frame and including a common axle, a plurality of input receivers coupled to the common axle, and a resistance member operably coupled to the common axle and operable to provide resistance against rotation of the common axle, a first exercise attachment including a first drive member operably coupled to a first input receiver of the plurality of input receivers of the common drivetrain, and a second exercise attachment including a second drive member operably coupled to a second input receiver of the plurality of input receivers of the common drivetrain.
