A bicycle trainer provides variable resistance to pedaling and allows for a rider to simulate a real-world bicycle course. The trainer engages both the front tire and the back tire of the bicycle and adjusts each according to the rider's preferences during a training session. The front tire lifts up and down as the bicycle moves forward and backward on the trainer. The back tire is adjusted by incorporating magnets thereon in the form of magnetic elements on a sleeve or a clip that engages the back tire and/or the back tire rim. The magnets on the back tire may also be attached to the spokes. The trainer includes magnets as well, usually of opposite polarity, and adds resistance to pedaling when the magnetic fields of the magnets interact to resist back tire revolution.

A bicycle training system and methods of using the same. The system includes a movement platform that rests on a support surface and supports a bicycle in an upright manner with respect to the support surface. The movement platform includes a support frame having a base and at least one upstanding arm that supportably engages a portion of a frame of the bicycle, a resistance assembly operatively coupled to a portion of a drivetrain of the bicycle that applies varying levels of resistance to the portion of the drivetrain, and a plurality of bushings isolating the base from the support surface. The plurality of bushings are spherical thereby permitting the movement platform to move with respect to the support surface in response to forces applied to the bicycle frame during use of the bicycle training system.

A measuring device for a pedal plane angle of a bicycle includes a pedal body, an angle sensing unit and a central processing unit (CPU). The angle sensing unit is disposed in an accommodating chamber of the pedal body, and senses an angle of the pedal body to send an angle sensing signal. The CPU analyzes the angle sensing signal to obtain angle data of the pedal body relative to an angle of a reference plane to accordingly learn an angle relationship between the pedal body and the reference plane. The angle relationship may coordinate with other sensing units, for example, data of a pedaling force sensing unit to mutually correct and analyze the data, so as to obtain correct pedaling force information. With the angle data, whether a pedaling angle of a rider is correct can be learned to prevent sports injuries caused by incorrect pedaling angles.

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.

Cycling training apparatus (1), comprising a structure (2) that is supported on the floor (151) and a belt (4) that is movable with respect to the structure (2) and forms a closed longitudinal loop on which a bicycle (100) can be supported and ridden, The apparatus (1) comprises a securing element (9; 29) with two opposite ends (10, 11; 30, 31). One end (10; 30) has a first connector (12; 32) configured to be attached to a bicycle (100). The opposite end (11; 31) includes a second connector (13, 33) configured to be attached to a fixed point, The securing element (9; 29) is flexible so that the straight line distance (D) between these ends (10, 11; 30, 31) is variable, enabling the bicycle (100) to move longitudinally over the belt (4). The connectors also allow for transversal movement and lateral tilting of the bicycle (100).
