A load applying device includes a rotary member rotatably supported on a base with a spindle, and a magnetic device adjustable concentrically relative to the rotary member, to adjust and to apply a retarding force against the rotary member. A lever may support the magnetic device, and has a curvature corresponding to that of the rotary member. The base includes a casing having two grooves for slidably receiving fasteners which may be threaded to the lever, for guiding the lever to move relative ...

A modular transmission assembly includes a housing, a drive wheel rotatably mounted the hollow housing, an idler wheel rotatably mounted in the hollow housing and driven by the drive wheel via a belt, a tension rod pivotally connected to the hollow housing and having a distal end abutted to the belt and a resistance device adjustably mounted on the hollow housing to provide different resistances to the idler wheel such that when the drive wheel is rotated, a force to drive the drive wheel to rot...

An adjustable magnetic resistance mechanism of an upright bike includes a fan-shaped adjustment board which is pivotably connected to the bike's frame and a magnet unit is connected to a distal end of the adjustment board. A connection board is connected to the adjustment board and a shaft of the flywheel extends through a curve slot of the adjustment board. Two ends of the shaft are supported on two support plates on two upright posts of the upright bike. An axle extends through a pivot hole in...

A resistance unit for an exercise device, such as a bicycle trainer, includes a magnetic member which cooperates with a rotating electrically conductive member to establish eddy current resistance to rotation of a rotatable member forming a part of the resistance unit. The resistance unit includes a body to which the rotatable member is mounted, and an adjustment mechanism is interconnected with the magnetic member and the body for adjusting the position of the magnetic member relative to the el...

A pedal powered exerciser including a pair of independent reciprocating push pedal drives. A pedal at each drive operates a chain trained between an idler axle and an independent live half axle. Inertial movement is sustained with a flywheel and overrunning clutch assembly at each live axle. Kinetic resistance at each live half axle can be selectively varied with a magnetic tension control assembly. A tubular framework supports the pedal slides, chains, flywheels, and magnetic tensioners. A pneu...

A force-retarding device for a stationary bicycle includes a supporting base, a flywheel provided on the supporting base, a transmitting element, a shaft combined with the flywheel and the transmitting element, and a movement-stopping base provided between the transmitting element and the shaft. The movement-stopping base has an annular vertical contact surface. At one side of the contact surface are orderly provided a first bearing, a separating ring and a second bearing. An annular sealer is p...

An exerciser apparatus is made up of front and rear base-mounted standards interconnected by a common intermediate frame having an adjustable seat portion and a pedal crank assembly beneath the seat portion which is provided with an adjustable brake to control the resistance to rotation of the pedal crank which is imparted through a V-belt drive into a front wheel mounted on the front standard. A speedometer senses the speed of rotation of the front wheel in response to rotation of the pedal cra...

In situ apparatus for exercising in which an operator grips suitable handles and actuates pedals while the angle of the body of the operator relative to a stationary frame varies continuously during each cycle. An upstanding arm is pivotally mounted on the frame. The operator actuated pedals are located on one end of the arm. Suitable linkages connect the pedals with the frame so that actuation of the pedals causes the angle of the arm to vary continuously. This arm supports the user such that w...

A novel stationary exercise bicycle and method for exercising on that bicycle is disclosed. The novel bicycle, comprising a frame having front and rear sockets, a seat mounted into the rear socket, and a handlebar mounted in the front socket, can advantageously be adjusted so that a rider can adopt different riding positions to simulate outdoor bicycle riding conditions.

A bicycle includes a frame and a wheel rotatably mounted in relation thereto. The wheel is drivable by two pedal devices including pedal-equipped arms. The two pedal devices are individually mounted in different bearings and connected to the wheel via two different transmissions, which separately co-operates with a mechanical clutch. The clutch includes a dog being movable to and from opposite shoulder surfaces of which a first one guarantees driving the wheel when the dog, in an active state, i...
