Abstract: 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.

Abstract: Power measurement device for a bicycle trainer, which device is built as a unitary relocatable device comprising an acceleration or velocity sensor, a microcontroller and a memory, wherein the device is equipped with or connectable to a power source, preferably a battery, and wherein the device is equipped with a communication facility to enable the device to wirelessly or through wires communicate with an external application device.

Abstract: 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.

Abstract: Method for operating a bicycle trainer, and such a bicycle trainer comprising a stand with a seat, handlebars and rotatable pedals, or such a bicycle trainer comprising a stand for mounting a bicycle frame with a seat, handlebars and rotatable pedals, wherein the stand incorporates an electronically variable brake acting directly or indirectly on the rotatable pedals with a braking resistance that depends on a computer-controlled predetermined setting, wherein the pre-determined setting is variable and wherein said setting depends on selected parameters to reflect a simulated surface condition of a road.

Abstract: Training apparatus arranged for supporting a bicycle, comprising a ground-supported or supportable frame that is at least provided with a supporting roll or rollers for a bicycle back wheel that are movable in the frame in vertical direction, wherein the suspension of said roll or rollers is arranged to convert relative horizontal movements of the roll or rollers into vertical movements thereby compensating and/or attenuating said horizontal movements by gravity.

Abstract: Input performance measurement system for a bicycle comprising a drive train, chain ring mounted on a crank, a chain that drives the bicycle's back wheel, and which bicycle has pedals mounted on crank arms and the crank, wherein the system comprises at least one sensor to respond to a force applied to the pedals and transmitted to the chain ring to produce an electronic signal relative to said force transmitted to the chain ring, wherein the sensor is embodied with at least one electrical coil, wherein the coil is supported by a device mountable on the chain ring so as to arrange at least one coil positioned adjacent to the chain ring and/or a crank arm, which element is movable with respect to one coil due to forces exerted on at least one of the pedals so as to vary the electrical impedance of said at least one coil.

Abstract: The invention relates to a quick release mechanism for securing and releasing a bicycle in a trainer, wherein said mechanism engages and secures the rear hub area of a bicycle without disassembly of said bicycle, comprising: (a) a housing adapted to slidably receive at least part of a piston, wherein said housing is mounted on a first hub supporting leg of said trainer; (b) a piston nesting within the housing and being slidable therein, wherein said piston has a first end and a second end, said first end bearing a first means for capturing a bicycle wheel hub; (c) means for slidably moving side piston within said housing in order to extend said first end toward the hub of a bicycle to secure said bicycle, including a lever mounted at the second end of said piston; (d) a second means for capturing said bicycle wheel hub, said capturing means being mounted on a second hub supporting leg of said trainer, wherein the hub supporting legs are mutually spaced to allow a bicycle wheel mounted on a bicycle wheel t

Abstract: The invention relates to a home trainer designed to accommodate a bicycle, comprising a brakable drive roll incorporated in a frame, which can be mounted in a friction coupling with a driven wheel of the bicycle. The frame is provided with a sub-frame that is rotatable about a first pivoting point, the drive roll being mounted in the sub-frame. The frame is further provided with a handle rotatable about a second pivoting point, which is adjustable between an operational position wherein the handle pushes the sub-frame towards the wheel such that the drive roll and the wheel maintain the friction coupling, and a neutral position wherein the handle releases the sub-frame such that the drive roll and the wheel do not engage.
