Control system of a cycling simulation device, said device comprising a support frame, with which a user carries out training by acting on the pedals of said bicycle, a flywheel rotating around a main shaft, connected to said coupling members, and a braking device, acting on said flywheel, comprising: a control logic unit, capable of connecting in transmission and reception with a remote device, by which a user can set one or more training parameters, and a torque sensor for detecting and sending to said control logic unit a signal related to the torque acting on said main shaft during the rotation of said flywheel, and said control logic unit being configured so as to adjust the braking force exerted by said braking device on said flywheel as a function of training parameters and of signal related to the torque acting on said main shaft detected by torque sensor.

A safety signal is sent to a relay coupled to a plurality of power leads of a motor wherein a default state of the relay is to short the plurality of power leads together and wherein the safety signal maintains the relay in an open state. The safety signal to the relay is deasserted in response to a determination that an unsafe condition has occurred.

An exercise bike operable while remaining stationary on a support surface. The exercise bike includes a bicycle frame with a pedal assembly coupled to a clutch mechanism that is movable between an unlocked state in which the pedal assembly drives a wheel in a first rotational direction and rotates relative to the wheel in a second rotational direction, and a locked state in which the pedal assembly is rotationally fixed to the wheel to drive the wheel in the first rotational direction and the second rotational direction, and a handlebar assembly. The handlebar assembly is coupled to the bicycle frame and includes a handlebar and a locking mechanism. The locking mechanism is moveable between an unlocked position in which the handlebar is allowed to rotate about an axis, and a locked position in which the handlebar is restricted from rotating about the axis. A control module may move the locking mechanism and the clutch mechanism between their respective locked and unlocked states.

An exercise machine includes a shaft configured to rotate about an axis; a spool configured to receive a strap and drive rotation of the shaft about the axis in response to movement of the strap; a flywheel configured to rotate about the axis; one or more conductive coils arranged to generate magnetic fields that induce eddy currents in the flywheel; a clutch configured to engage and disengage transmission of torque between the spool and the flywheel; and a spring arranged around the axis, the spring configured to exert a return torque on the spool about the axis in response to rotation of the shaft.

A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

An exercise apparatus includes a rope wrapped around a spindle having a one-way clutch rotatably mounted on a driveshaft. The driveshaft is driven by a motor controlled by a motor controller. The controller is capable of driving and braking the motor such that the driving torque and the braking torque can be set at different values to ensure the safety of the apparatus and user.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

A portable exercise device provided includes: a base disc, two pulley assemblies, a support plate, and a fan wheel assembly. A support plate is disposed on the base disc, the two pulley assemblies are provided on the base disc, and the fan wheel assembly is provided on the support plate, so that the fan wheel assembly and the two pulley assemblies are vertically arranged on top of each other, thereby reducing the overall volume. More preferably, because the volume is reduced, the user can arbitrarily move and hang the portable exercise device at the desired position, and because the portable exercise device of the invention can be hung at different positions, which allows the user to train different muscles according to the different positions.
