[0048] The present invention described herein broadly provides for a bicycle handlebar extension apparatus 10 and an associated bicycle exercise arrangement 40. Such apparatus 10 finds particular application on providing stability and ergonomics when used with a bicycle 8 supported on an indoor bicycle trainer 38, although such use is non-limited.

[0049] Referring now to the accompanying figures, there is shown one embodiment of such bicycle handlebar extension apparatus 10. In the exemplified embodiment, apparatus 10 typically comprises a strut arrangement 12 and a brace 22 with handlebar receptacle 28 for operatively receiving handlebars 30.

[0050] The strut arrangement 12 has a lower end 14 which is configured to releasably engage a front axle 16 of a bicycle 8 and an upper end 18 configured to releasably engage a handlebar stem 20 of said bicycle 8, as shown.

[0051] In the exemplified embodiment, the strut arrangement 12 comprises two struts operatively locatable on either side of a front wheel 34 of the bicycle 8 in order to straddle said wheel 34, as shown. In an embodiment, the strut arrangement 12 may be configured to abut against a frame 32 of the bicycle 8, for example in order to impede the front wheel 34 from turning, to provide additional stability to apparatus 10, etc.

[0052] Typically, the lower end 14 of the strut arrangement 12 is configured to releasably engage the front axle 16 by means of a quick-release attachment, as known in the art. Similarly, the strut arrangement 12 may be configured to engage the front axle 16 by defining axle apertures for receiving said axle 16 therethrough, or the like. In such an embodiment, the strut arrangement 12 may be biased to sandwich the front axle 16 between the respective struts straddling the front wheel 34.

[0053] In one embodiment, the strut arrangement 12 is configured to be lengthwise adjustable to enable fitment to various sized bicycles, e.g. telescoping struts, or the like. The upper end 18 of the strut arrangement 12 is typically configured to releasably engage the handlebar stem 20 by defining a friction-fit or interference-fit clip to clip onto said handlebar stem 20. In an embodiment, the upper end 18 of the strut arrangement 12 is configured to releasably engage the handlebar stem 20 by means of a suitable clamp. Variations hereon are possible and within the scope of the present invention.

[0054] Apparatus 10 also includes a brace 22 which is hingedly attached at a bottom end 24 thereof to the upper end 18 of the strut arrangement 12, as shown. The brace 22 further defines at a top end 26 thereof a pivotable receptacle 28 which is configured to receive handlebars 30.

[0055] In the exemplified embodiment, the brace 22 comprises two beams extending from the strut arrangement 12 to the handlebar receptacle 28. In an embodiment, the brace 22 is configured to be lengthwise adjustable to enable ergonomic adjustment e.g. telescoping brace members, or the like. Typically, the hinge at the bottom end 24 of the brace 22 and the pivotable receptacle 28 at the top end 26 are adjustable and releasably securable in order to adjust angles between the strut arrangement 12, brace 22 and receptacle 28.

[0056] In this manner, the strut arrangement 12 can be operatively engaged with the front axle 16 and handlebar stem 22 to provide stationary stability to the bicycle 8 whilst the angles between the strut arrangement 12, brace 22 and receptacle 28, i.e. handlebars 30, are adjustable to facilitate desired rider ergonomics.

[0057] In an embodiment, the pivotable receptacle 28 is configured to receive a variety of bicycle handlebars, as required. In the exemplified embodiment, the apparatus 10 includes handlebars 30 received within the receptacle 28, such as triathlon bars.

[0058] With reference now to FIGS. 5 and 6 of the accompanying figures, the skilled addressee is to appreciate that variations are possible in the manner in which the strut arrangement 12 releasably engages the front wheel 34 of bicycle 8. In the exemplified embodiment, the strut arrangement 12 includes a clamp assembly 42 which is configured to clamp onto the front wheel 34, as shown. Typically, the clamp assembly 42 is positioned between the two struts proximate the upper end 18 of the strut arrangement 12, as shown, with the clamp assembly 42 configured to be arrestably slidable along the strut arrangement 12 to facilitate clamping onto front wheels of varying sizes. The clamp assembly 42 typically includes an abutment surface, such as a rubber pad or the like, which is urged against the wheel 34 to clamp the wheel 34 in place. The clamp assembly 42 is typically arrestable by means of an infinitely adjustable releasable detent 44, such as a ratchet mechanism to facilitate clamping onto the wheel.

[0059] In such an embodiment, the strut arrangement 12 typically also includes a front wheel cradle 46 at the lower end 14 thereof, as shown, with the cradle 46 configured to receive the front wheel 34 therein. In an embodiment, the front wheel cradle 46 also defines a support foot 48 which is configured to support the bicycle on a level surface.

[0060] It is further to be appreciated that the present invention also includes a bicycle exercise arrangement 40 which comprises the bicycle 8 mounted on a stationary bicycle trainer stand 38 with apparatus 10, as described herein, fitted thereto.

[0061] While the present invention described herein was generally done so in reference to a bicycle 8, the skilled addressee is to appreciate that said apparatus 10 may find similar application on cycles other than conventional two-wheeled cycles, such as tricycles, quadricycles and/or similar human-powered vehicles. Accordingly, suitable variations on the apparatus 10 and arrangement 40 described herein are possible and within the scope of the present invention.

[0062] Applicant believes it particularly advantageous that the present invention provides for apparatus 10 configured to enable a more upright body position for a cyclist, particularly when using an indoor trainer 38. Apparatus 10 is generally able to decrease loads on the cyclist's lower back, neck, and upper limbs during use as compared to conventional handlebars. Apparatus 10 is further adaptable to be fitted to most bicycles and is fully adjustable to suit any desired ergonomics of a cyclist.

[0063] The skilled addressee is further to appreciate that apparatus 10 enables customisation of cyclist ergonomics according to requirements. For example, a cyclist seating position can be adjusted to target specific muscle activation during cycling, which may improve cycling performance, facilitate in injury recuperation, and/or the like.

[0064] Importantly, apparatus 10 facilitates stability for use on an indoor bike trainer, particularly where lack of both wheels rotating and bicycle forward motion promotes stability due to gyroscopic effects and angular momentum. In addition, apparatus 10 is typically quickly and easily removable to allow conventional use of the bicycle off the trainer 38.
