An exercise assembly for physical therapy and rehabilitation includes a bicycle and a treadmill. The bicycle has a pair of front forks. The treadmill has a belt that is configured to rotate. A coupler is coupled to the treadmill. The coupler is configured to couple to the front forks. The coupler is positioned to reversibly couple to the front forks to couple the bicycle to the treadmill such that a rear wheel of the bicycle is positioned on the belt. The belt is positioned to rotate the rear wheel such that rotary motion is transferred through a pair of pedals of the bicycle to legs of a user who is positioned on the bicycle.

A bicycle rollers assembly (10) having a rear and a front and further having a rear pair of parallel rollers (12) each having an axis of rotation, and adapted to support a rear bicycle wheel having an axle parallel to the axes of rotation. The rollers (12) are spaced so as to support the rear bicycle wheel with the lowest part of the bicycle wheel positioned between the rollers. Also, a front support structure (18) supports a front bicycle fork support element (24) so as to permit horizontal rotation, and this support element includes a support (26) for each arm of a bicycle fork (29).

A bicycle simulator is arranged by arranging a front wheel and a rear wheel of a bicycle on the same plane. The bicycle simulator includes a front roller that supports a front wheel of a bicycle that is mounted and rotates together with a rotation of the front wheel, The bicycle simulator further includes a rear roller that supports a rear wheel of the bicycle and rotates together with a rotation of the rear wheel. A first support point at which the front roller supports the front wheel and a second support point at which the rear roller supports the rear wheel are arranged on the same plane. Not only a substantially flat ride path but also various ride modes in which an inclination angle may be adjusted according to a ride mode may be implemented, and a dynamic experience similar to the actual ride situation may be enjoyed.

Provided is a bike training device having a frame that rotatably supports a pair of rear rollers spaced a distance apart from each other along a longitudinal axis of the frame to rotatably support a rear wheel of the bicycle that rolls on both of the rear rollers. A front roller is spaced apart from the rear rollers along the frame a suitable distance to rotatably support a front wheel of the bicycle. A guide apparatus comprising a connection mechanism that is pivotally supported at an elevation vertically above the frame cooperates with a rear hub of the bicycle and allows for lateral movement of the rear wheel in axial directions along the rear rollers during rotation of the rear wheel of the bicycle, but limits an extent of the lateral movement to maintain the rear wheel between terminal lateral ends of the rear rollers.

A bicycle trainer for removably loading a bicycle with at least a back wheel, where the bicycle trainer comprises a floorstanding frame with a wheel supporting roller at a rear end and a fork supporting unit at a front end, wherein the fork supporting unit is pivotally supported by the floorstanding frame enabling the fork supporting unit to move, where the fork supporting unit and the floorstanding frame connect to each other with a hinge enabling movement of the fork supporting unit in a longitudinal direction of the floorstanding frame, wherein the fork supporting unit is spring-loaded with a spring at or near the hinge to provide the fork supporting unit with a preferential upright position at right angles with the floorstanding frame such that whenever the bicycle is moved, said bicycle returns to an average position on the bicycle trainer with the fork support unit perpendicular to the floorstanding frame.

A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.

A bicycle trainer fastening device, disposed on a bicycle trainer, includes a hollow tube, a first fastening member and a second fastening member. The hollow tube includes a first assembly portion and a second assembly portion at two opposite ends thereof. The first fastening member is disposed correspondingly to the first assembly portion, and includes a first through opening correspondingly in communication with the hollow tube and having an aperture corresponding to an inserting shaft of a bicycle. The second fastening member is disposed correspondingly to the second assembly portion, and includes a second through opening correspondingly in communication with the hollow tube and an aperture corresponding to the inserting shaft. By selecting the first through opening and the second through opening corresponding to the shaft diameter of the inserting shaft and replacing the first fastening member and the second fastening member, the scope of applicability can be maximized.

A wheelchair training system that comprises: a platform (110) that receives the wheelchair; two elongated parallel rollers (250) that are mounted on the platform (110) and are in tangential contact with two rear wheels (150, 160) of the wheelchair such that the two rollers (250) spin when the two rear wheels (150,160) rotate; and a spinning resistance control system (300) mounted on the platform (110) includes a magnet (310) that moves in different positions so that an overlapping area between a magnetic field generated from the magnet (310) and end of the two rollers (250) varies due to the magnet (310) being moved to the different positions. The magnetic field of the magnet (310) induces an eddy current in the two rollers (250) and generates a resistive force against rotation of the two wheels (150,160).

A treadmill system includes a deck, an endless tread belt covering at least a portion of the deck, and a motion transducer positioned to detect movement of the tread belt. The treadmill system also includes a processor and memory where the memory includes instructions executable by the processor to receive an output of the motion transducer, determine an exercise type performed on the tread belt, and calculate an amount of work performed by a user on the tread belt based on the output of the motion transducer and the determined type of exercise.
