The fork 20 is a typical construction for receiving wheels. Accordingly, the at least one front wheel 3 is rotatably mounted in between a first leg 20a of the fork 20 and a second leg 20b of the fork 20. More specifically, the at least one front wheel 3 is inserted in between the legs of the fork 20 and fastened on the outside on both sides with nuts or levers.

[0020] In reference to FIG. 1 and FIG. 2, wherein the biking device is in a bicycle mode, the present invention comprises a bent front leg 22. In this configuration, the bent front leg 22 is terminally connected to a first end 21 of the stem 16 and the at least one front wheel 3 is detachably mounted onto the bent front leg 22. In other words, in this configuration, the present invention has a quick-change front wheel. Further, when the biking device is in a bicycle mode, the drive box 2 comprises a bent body 2b, as seen in FIG. 1 and FIG. 2. This is so that, by bending the drive box 2 the rear wheel may be placed in the center line on a free-standing axle. In the conventional construction, wherein the wheel is mounted within a fork shaped frame, if the at least one rear wheel 4 is broken, it is very difficult and complicated to detach the rear wheel 4 from the frame 1. With the bent drive box 2b and a freely fixed axle, the at least one rear wheel 4 can be quickly removed and reinstalled. It should be noted that the at least one front wheel 3 and the at least one rear wheel 4 may be mounted onto the bent front leg 22 and the bent drive box 2b respectively by means of any fasteners or fastening techniques that are known to one of ordinary skill in the art, as long as the intents of the present invention are not altered. Examples of such fasteners include, but are not limited to a quick-change connection, a plugin connection, a screw-together connection, a flange-connection, welding connection, lever operated lock etc.

[0021] In order to provide comfort and a relaxing positioning for the cyclist/user, the present invention comprises a seat post 23, and a saddle 24.

It should be noted that the saddle 24 and the seat post 23 may comprise any other shape, size, dimension, components and arrangement of components that are known to one of ordinary skill in the art, as long as the intents of the present invention are not altered. Further, in order to steer and maneuver the biking device, the present invention comprises a handlebar 25, wherein the handlebar 25 is terminally connected to a second end 26 of the stem 16, opposite to the at least one front wheel 3. Thus, this arrangement enables users to steer the handlebar 25, leading to steering of the at least one front wheel 3, so as to direct the biking device in a direction determined by the user.

[0022] As seen in FIG. 1 through FIG. 7, the plurality of pedals 6 comprises a first pedal 27a and a second pedal 27b. Preferably, the first pedal 27a extends laterally from a first surface 28 of the drive box 2 and the second pedal 27b extends laterally from a second surface 29 of the drive box 2, wherein the first surface 28 is positioned opposite to the second surface 29 across the drive box 2. This is so that, the first end 9 of the drive box 2 is coupled to the plurality of pedals 6 by a bar that extends through a position where a chain ring of the bicycle may be further coupled to each pedal arm of each pedal.

[0023] In the preferred embodiment of the present invention, the driving mechanism 5 is a hydraulic driving mechanism. To that end, the drive mechanism 5 comprises a hydraulic pump 30, a hydraulic motor 31, a plurality of fluid transfer tubes 32, a first continuous shaft 33, and a second continuous shaft 34. Preferably, the plurality of fluid transfer tubes 32 is connected between the hydraulic pump 30 and the hydraulic motor 31. Hydraulic mechanisms are typically powered by oil, but other liquids may be used as well. The plurality of fluid transfer tubes 32 enables pressurized oil to get pumped into the cylinder barrels in the hydraulic motor 31 and creates the power behind the motion. As seen in FIG. 7, the first continuous shaft 33 engages through the hydraulic pump 30 and the first continuous shaft 33 is connected in between the first pedal 27 and the second pedal 28. This is so that pedaling of the plurality of pedals 6 pumps the pressurized liquid into the hydraulic motor 31. To further transfer the power to the wheels, the second continuous shaft 34 engages through the hydraulic motor 31 and the second continuous shaft 34 is terminally connected to the at least one rear wheel 4. It should be noted that, any other connecting mechanism that is known to one of ordinary skill in the art may be employed for the smooth functioning of the hydraulic modular biking device.

[0024] In order to accomplish connection between the various components of the present invention to the drive box 2, the present invention comprises a first port 35 and a second port 36. As seen in FIG. 6, the first port 35 is positioned adjacent the first end 9 of the drive box 2 and the second port 36 is positioned adjacent the second end 10 of the drive box 2. This is so that the plurality of pedals 6 is detachably connected to the driving mechanism 5 through the first port 35 and the at least one rear wheel 4 is detachably connected to the driving mechanism 5 through the second port 36. In other words, the first port 35 and the second port 36 act as attachment points for connecting the plurality of pedals 6 and the at least one rear wheel 4 to the driving mechanism 5. However, any other mode of connection may be employed, as long as the intents of the present invention are not altered.

[0025] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
