A sensor system for a bicycle. The system system includes a magnetic field sensor and an acceleration sensor unit having at least one acceleration sensor, and an evaluation unit that is designed to acquire signals from the magnetic field sensor and the acceleration sensor unit. The magnetic field sensor and the acceleration sensor unit are designed for attachment to a wheel of the bicycle. The magnetic field sensor and the acceleration sensor unit are fixed relative to each other and are situated at a predefined distance with respect to an axis of rotation. The evaluation unit is designed to evaluate the signals of the magnetic field sensor and the acceleration sensor unit to ascertain a rotational speed and/or orientation of the magnetic field sensor and/or acceleration sensor unit with respect to the axis of rotation.

A single-sprocket system for integration into a bicycle trainer, the system including a sprocket having teeth about a perimeter of the sprocket, a first planar side, and a second planar side, wherein the teeth of the sprocket are configured to engage a chain of a bicycle mounted to the bicycle trainer. The system further includes a first chain guide adjacent the first planar side of the sprocket, wherein the first chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the first planar side, and a second chain guide adjacent the second planar side of the sprocket, wherein the second chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the second planar side.

An improved method of physiotherapy includes loading muscles of a torso of a user with a torque acting substantially about a vertical axis; and the user using an exercise equipment while the torso is loaded with the torque.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.

A flexible trainer stand for indoor cycling includes a bracket, a flat plate, a first guide portion, a second guide portion, and elastic devices. The first guide portion and the second guide portion can slide relative to each other, which is configured for simulating forward and backward movement of a bike generated when a user accelerates and sprints. The first guide portion and the second guide portion can be inclined under an action of the elastic device, which is configured for simulating left and right inclination of the bike generated when the user is cycling and exerting force. A lifting device is arranged on the flat plate, which is configured for simulating position changes of the bike in a vertical direction when a slope changes. Somatosensory feedback of the user during outdoor cycling is truly simulated, and a feedback force can be adjusted.

A training wheel training device is provided for use in connection with a bicycle having first and second training wheels mounted thereto. The training wheel device includes a block having a bottom surface engageable with a supporting surface and an upper surface spaced therefrom. The upper surface includes a recess formed therein. A wheel support surface has at least a portion spaced from the upper surface and partially defines the recess. The wheel support surface is adapted for receiving the first training wheel.

The bicycle ramp of the present invention is foldable and easily transportable. The bicycle ramp of the present invention may be built directly onto a utility trailer with a foldable gate and wheels and thus is transportable to be pulled along the back of a suitable vehicle using the hitch. The bicycle ramp of the present invention creates an inclined surface for bicycle riding applications, including the teaching of a beginning cyclist skills such as balancing and pedal. There is a receiving slot to engage the rear wheel of the bicycle at the flat upper section of the bicycle ramp. The receiving slot stabilizes the bicycle in a static position until a releasable stopper is released to launch the rider down the angled sections of the bicycle ramp.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.
