## Abstract

The invention provides an exercise machine (10) of the type which have pedals (38) or foot plates through which a person can, in use, transfer kinetic energy to the machine, which machine comprises a means for vibrating the pedals or foot plates during exercise. The exercise machine includes a mechanism (40) to engage or disengage the vibration.

## Claims

### Claim 1

A stationary exercise bicycle, the stationary exercise bicycle comprising:
a pair of rotatably lockable pulleys respectively mounted on each side of the stationary exercise bicycle and with a circumference similar to a rotation circumference of a pair of rotating pedal shafts of the stationary exercise bicycle;
a pair of crank arms rotatably mounted to the stationary exercise bicycle, wherein one end of each crank arm of the pair of crank arms is connected through a bottom bracket of the stationary exercise bicycle wherein the bottom bracket extends through a middle of the pair of rotatably lockable pulleys;
a pair of shafts, wherein each shaft of the pair of shafts is rotatably mounted through a hole defined in a free end of a respective crank arm of the pair of crank arms with one end of the respective shaft extending inwards towards the stationary exercise bicycle and provided with a coaxial pulley respectively engaging a respective rotatably lockable pulley of the pair of rotatably lockable pulleys with an outwardly extending end of the respective shaft provided with a socket for receiving a respective rotating pedal shaft of the pair of rotating pedal shafts of a bicycle pedal, wherein the socket is offset from an axis of the shaft; and
a locking mechanism for rotatably locking the pair of rotatably lockable pulleys.

### Claim 2 (depends on 1)

The stationary exercise bicycle as claimed in claim 1, wherein the locking mechanism for rotatably locking the pair of rotatably lockable pulleys includes a pair of retractable laterally extending arms, wherein each of the pair of retractable laterally extending arms, when extended, engages with the pair of rotatably lockable pulleys to rotatably lock the pair of rotatably lockable pulleys to prevent rotation of the pair of rotatably lockable pulleys.

### Claim 3 (depends on 2)

The stationary exercise bicycle as claimed in claim 2, wherein the pair of retractable laterally extending arms simultaneously engage the pair of rotatably lockable pulleys.

### Claim 4 (depends on 3)

The stationary exercise bicycle as claimed in claim 3, wherein each arm of the pair of retractable laterally extending arms is in the form of a pin and extends into a respective hole formed in a respective side of the pair of rotatably lockable pulleys to lock the pair of rotatably lockable pulleys.

### Claim 5 (depends on 4)

The stationary exercise bicycle as claimed in claim 4, wherein the locking mechanism includes a housing and the pair of retractable laterally extending arms mounted inside the housing, wherein the pair of retractable laterally extending arms are extendable laterally outward out of the housing.
