The present invention relates to an indoor stand with degrees of movement side gear for use with bicycles comprising two main components assembled in an integrated manner: 1) a rear roller and 2) a front stand that attaches to the fork, instead of the front wheel, in which springs or cushions below the front fork allow degree of lateral movement to the left and right, in which a main bar is coupled to the base by an axis that allows the lateral movement degrees with stability. The presence of these components makes the present invention well simulate the experience of pedaling outdoors and working on the user's shoulders, arms and abdomen.

A bicycle trainer has a stand, a resistance generating mechanism carried by the stand, and a decoupling hub assembly carried on the stand. The decoupling hub assembly has a torque coupler operably connected to the resistance generating mechanism. The torque coupler has a coupling portion configured to engage a coupling part of a drive body assembly on a bicycle. The coupling portion is exposed to an exterior of the stand engages the drive body assembly, which is rotationally driven by the drive train of the bicycle.

A method and apparatus for detecting and varying indoor bicycle trainer pedaling resistance in varying manner to replicate the effects of increased system inertia. The method uses a high-resolution position detection method to correlate crank acceleration and deceleration to resistance level. The effects of inertia are replicated by limiting acceleration of the crank by application of increased resistance unit resistance and deceleration via reduction of the resistance applied to pedaling. Thus, the decreased magnitude of acceleration events imitates the effects an increased system mass (inertia) perceived by the rider, enhancing “road feel”, which is synonymous with the feeling of accelerating one's own inertia while cycling outdoors. This is accomplished through sensors used to detect or determine crank position with a high resolution, a method of providing and varying resistance, such as an eddy current resistance device using either electromagnets or permanent magnets and a microcontroller to calculate the required magnetic field strength and adjust the field strength or magnet position in the resistance unit to facilitate the change required as determined by the outlined algorithm.

A steering assembly for a mounted bicycle is disclosed herein. The steering assembly includes a support base and at least one omnidirectional roller assembly extending from a bottom surface thereof. The at least one omnidirectional roller assembly is operatively disposed in direct contact with a ground surface and is structured to facilitate movement of the support base along the ground surface in a plurality of different arcuate and linear paths to accommodate varying trail measurements of a bicycle. The varying trail measurements of the bicycle are defined by varying angles of the bicycle relative to the ground surface during operative use of the steering assembly.

A residual anaerobic work capacity calculating method includes a step (S1) of obtaining a heart rate, and a step (S2, S3) of calculating a residual anaerobic work capacity based on the obtained heart rate and a relationship between the residual anaerobic work capacity and the heart rate. This method need only measure the heart rate when calculating the residual anaerobic work capacity, and obviates the need to measure power by using an expensive power meter.
