A bicycle trainer including folding legs and a vertically adjustable frame member supporting an axle and cassette where a rider mounts the rear frame, such as dropouts, of a conventional bicycle with the rear wheel removed. The trainer includes a flywheel with a magnetic brake assembly controlled through an open protocol and configured to receive wireless transmitted signals from an app running on a smart phone or other such applications. The flywheel assembly also includes a bracket coupling the magnetic brake with a frame. A strain gauge is mounted on the bracket to detect torque, which is used to calculate a rider's power while using the trainer.

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.

Apparatus, system and method for power measurement

A power measurement assembly mounted within an axle. In a specific example, the axle is a spindle that is interconnects the cranks of a bicycle, exercise, bicycle, or other fitness equipment. The power measurement assembly may include strain gauges connected with an appropriate circuit (e.g., Wheatstone bridge) that provides an output of the force on the axle by a rider pedaling the crank. In the case of an axle, the strain gauges measure the torsion due to the applied torque on the crank. The value is converted to a power value by a processor and that value is then wirelessly transmitted for display. The processor and/or the transmitter may be mounted within the axle. A separate power measurement assembly may be mounted on one of the cranks, which may include its own processor and transmitter or may take advantage of the processor and transmitter within the axle.

An indoor cycling device including a unique frame arrangement with fore and aft adjustable seat and handlebar assemblies. The assemblies support a seat and handlebars for fore and aft movement. The assemblies may include a receiver with an elongate aperture with a slider positioned therein. The slider defines a first channel receiving a moveable member. A handle is operably coupled with the member to move the member within the channel in a first direction or a second direction such that a frictionally coupling is caused between the slider and the receiver when the slider is moved in the first direction and releases the coupling when the slider is moved in the second direction.

Exercise bicycle frame with bicycle seat and handlebar adjustment assemblies

An exercise bicycle including a frame supporting a flywheel. A magnetic brake assembly includes a brake arm pivotally mounted to the frame and including at least one magnet. The magnet is positioned adjacent to the flywheel and not in contact with the flywheel, the position of the magnet relative to the flywheel inducing a magnetic braking force on the flywheel. The pivot of the brake arm is positioned such that a pivot force vector induced on the brake arm by the magnetic braking acts to pivot the brake arm away from the flywheel.

Exercise bicycle with magnetic flywheel brake

An exercise bicycle including a frame supporting a wheel such as a flywheel. A brake assembly (or resistance assembly) including a brake arm is pivotally coupled with the frame. The brake arm assembly includes a brake pad engaging the flywheel to alter the power needed to rotate the flywheel during exercise. A brake adjustment assembly is operably coupled with the brake arm. The adjustment assembly includes a shaft rotatably supported on the frame and mounted to be translated toward the flywheel while being restricted from translating away from the flywheel. A spring is positioned between the threaded shaft and the brake arm whereby rotation of the shaft increases or decreases compression of the spring thereby increasing or decreasing a frictional force between the brake pad and the flywheel.
