Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a bicycle exercising device or exerciser, and more particularly to a bicycle exercising device having a handle adjustable toward and away from the seat and the users, for allowing the bicycle exercising device to be suitably operated by users of different sizes or heights.

2. Description of the Prior Art

Typical bicycle exercising devices comprise a transmission box driven by foot pedals, and a handle extended or provided on top of the base, for supporting the upper portions of the users. Normally, the handle portions are solidly and firmly disposed and secured on top of the base, and may not be moved or adjusted relative to the base and the seats and the users, such that the typical bicycle exercising devices may not be suitably operated by users of different sizes or heights.

For example, U.S. Pat. No. 4,688,790 to Hokajärvi discloses one of the typical bicycle exercising devices which also comprises a pair of foot pedals provided to be rotated or driven by the users, and a handle solidly and firmly disposed and secured on top of the base. The handle also may not be moved or adjusted relative to the seats and the users, such that the typical bicycle exercising devices also may not be suitably actuated or operated by users of different sizes or heights.

U.S. Pat. No. 4,871,164 to Tseng discloses another typical bicycle exercising device which also comprises a pair of foot pedals provided to be rotated or driven by the users, and a handle pivotally or rotatably coupled to a wheel via a gearing device and/or a chain and sprocket coupling device, for allowing the handle to be moved or pulled alternatively toward and away from the seats and the users. However, the handles should be alternatively pushed and pulled toward and away from the seats and the users, but also may not be adjusted relative to the users, such that the typical bicycle exercising devices also may not be suitably actuated or operated by users of different sizes or heights.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional bicycle exercising devices.
