Device (1) for cycling training that comprises a bicycle which can be integral with the device or not, a support (2), a drive system (3) and a pendulum (6) that joins the support (2) to the drive system (3). In the device, the pendulum (6) is rotationally attached to the support (2) by an upper end (2a) by the upper end (6a) of the pendulum (6), and this allows the swinging motion of the bicycle with the cyclist on it. The device (1) further comprises actuators (9), which extend from a lower end (6b) of the pendulum (6) to a base (2b) of the support (2), and are responsible for damping the swing. At the same time, the drive system (3) is also rotationally connected to the lower end (6b) by an upper part (3a) of the drive system (3) and to the support (2) by means of a guide mechanism (15) through a lower part (3b) of the drive system (3).

Disclosed is a hydraulic damping device level riding platform with adjustable resistance, which comprises a frame body, a shaft mechanism, a flywheel and a hydraulic damping mechanism, the shaft mechanism is arranged on the frame body, one end of the shaft mechanism is connected with the hydraulic damping mechanism and another end of the shaft mechanism is connected with the flywheel. The hydraulic damping mechanism comprises: a cavity; a rotating disc provided with blades, the rotating disc is arranged in the cavity; and a liquid level height adjusting mechanism movably connected inside the cavity to control a liquid level height in the cavity. The liquid level height of the liquid in the cavity is controlled through the liquid level height adjustment mechanism, so as to realize the control of the resistance of the rotating disc to the liquid.

Disclosed is a hydraulic damping device with adjustable resistance and a riding platform. The hydraulic damping device with adjustable resistance comprises a support frame, a rotating mechanism movably connected to the support frame, a hydraulic damping mechanism arranged at one end of the rotating mechanism and an inertia wheel detachably connected to an other end of the rotating mechanism, and the hydraulic damping mechanism comprises a shell and a rotating disc connected with the rotating mechanism extending into the shell, at least one blade is arranged on the rotating disc, and the blade is connected with the rotating disc in an adjustable angle to provide resistance at a corresponding angle. The angle of the blade relative to the rotating disc is adjusted so that when the blade rotates with the rotating disc, different from the resistance generated by the damping liquid in the shell, different resistance effects are provided.

An optimal bicycle frame size based on operational characteristics provided by a rider when riding a dynamic fit unit is determined. A best-fit bicycle frame size that is a closest match to the optimal frame size is determined. At least one of the optimal X,Y location of the bicycle's handlebar relative to the bottom bracket, and the optimal X,Y location of the bicycle's seat relative to the bottom bracket, is determined. A stem and spacer from a list of available stems and spacers that will best fit between the head tube of the best-fit frame and the optimal X,Y location of the handlebar is determined. A seat post from a list of available seat posts that will best fit between the seat tube of the best-fit frame and the optimal X,Y location of the seat is determined. A list of the best-fit frame, the best fit stem and spacer, and the best fit seat post, is produced.

An exercise machine, such as indoor cycle, including a multi-function wheel brake actuator. A braking force is induced on a wheel, such as through eddy currents or frictionally, by finely or coarsely adjusting the brake actuator. The brake actuator may thus include a knob whereby a user may finely adjust the braking force on the wheel and a lever to actuate interval settings whereby the brake actuator provides set positions of braking resistance. The exercise machine may further include a pop-pin assembly with an over-center cam mechanism to clamp members together. The pop-pin assembly also includes a fine adjustment to adjust the clamping force. So, for example, the seat stem may be clamped to the seat tube, or the handlebar stem clamped to the head tube, with a lever actuating the over center mechanism.

Athletic performance sensing and/or tracking systems include components for measuring or sensing athletic performance data and/or for storing and/or displaying desired information associated with the athletic performance to the user (or others). Such systems can allow users a wide variety of options in creating workouts, selecting and presenting media content during the athletic performance, etc., e.g., to help keep users entertained and motivated. In some instances, user feedback may be used, optionally in combination with objective data relating to a workout, to control features of the workout routine, to control the music or other media content selected and/or presented, and/or to control features of future workout routines and/or the presented media content.

A replacement bicycle stem is disclosed herein. In particular, prior to operation of a bicycle in a stationary environment, the bicycle stem, if present, is removed and replaced with the replacement bicycle stem disclosed herein. The replacement bicycle stem is intended to rotate or turn with the handlebars, but independent of the steer tube and front wheel. More specifically, the replacement stem includes a main body with a mounting channel at one end and a handlebar clamp at another end. At least one bearing is disposed within a portion of the mounting channel for engagement against the steer tube. The at least one bearing allows or facilitates rotation of the stem about the steer axis independent of or substantially independent of the steer tube.
