Description

Description (-i Background dogg UNLEASHED is a bike formulated to give better weight distribution for easier IN lift and balance to power control. A third leg with an omnidirectional wheel allows the rider to maintain a wheel stand, whilst also allowing the rider to follow any direction.

tr- O dogg UNLEASHED is a serious bike with a specific weight to balance concept Cc behind it.

dogg UNLEASHED contains a series of innovative design features that allow the 00 rider to perform the wheel stand with a level of skill and ease not afforded by Spreviously patented bike designs with similar intentions. These features and the key differences to existing patented designs are described below.

(Ni Description of Key Design Features Figure 1 shows the dogg UNLEASHED.

The four key innovative design features illustrated on this picture are: A. Complementary Seating Angle (also shown in Figure 2) B. Innovative Third Leg with Omnidirectional Wheel (also shown in Figures 3 and 4) C. Innovative Back Drop Out (where bike allows for the third leg to be fitted) D. Innovative Wider Rear Tyre The key difference between the dogg UNLEASHED and other patented designs which aim to assist riders in performing wheel stands is the innovative third leg and weight distribution. The dogg UNLEASHED has a weight distribution that puts of the rider's centre weight over the bicycle's rear wheel. This is achieved with the innovative third leg and seating position This innovative weight distribution makes certain stunts involving balancing on the rear wheel of the bike more easily achievable than with bikes currently patented or available on the market.

The stunts that can be performed more easily using the dogg UNLEASHED, compared to a normal BMX bike, involve balancing in the mono position (balancing on rear wheel) at varying speeds and with varying rotational manoeuvrability.

Using a normal BMX bike, perfecting stunts in which the bike is balanced on the rear wheel may take years. The time to perfect these stunts can be reduced significantly using the dogg UNLEASHED due to the safer and less strenuous riding environment created by the innovative weight distribution.

As a result of the innovative third leg and seating position, the rider is using less energy to bring and maintain the bike into the mono position. Also due to this seat position, the bike will maintain the mono position while remaining in a seated position without needing to peddle.

SThe rider is able to achieve the mono in a significantly shorter time spanas strength c and balance are not the most important attributes needed by the rider, as opposed to a normal BMX bike. This makes it safer than a normal BMX because bringing a normal BMX to the mono position requires greater skill, balance and strength The dogg UNLEASHED reduces the possibility of injury by giving the rider ease with regard to lifting control without needing considerable strength balance and Scontrol.

SComplementary Seating Angle A standard BMX type bike has the seat horizontal to the body of the bike. The seat on the dogg UNLEASHED is set at an innovative angle, giving rear weight Sdistribution for easier lift into the mono position (refer to Figures 1 and 2).

Innovative Third Leg with an Omnidirectional Wheel Although other bikes have been patented with third wheels to stop the bike from flipping, this one is unique in that it uses an omnidirectional wheel, which has never been used on a bike before. This is an omnidirectional wheel that allows the rider to have his weight follow the bike in its exact weighted route (in two directions concurrently). This allows a mono with angle and turn but without friction, giving the rider a smoother and safer mono turn. The omnidirectional wheel is also made from poly plastic caster with a weight baling of 400 kg making it virtually indestructible (refer to Figures 3 and 4).

The strength and ability of the omnidirectional wheel to have the ability to follow any direction with less friction is the key design feature that separates this innovative third leg from other patented inventions.

In addition the dogg UNLEASHED third leg is designed with 2 positions, the starter and the pro position, the latter enabling more front wheel vertical lift of the bicycle.

This 2 position third leg approach is unique to the dogg UNLEASHED design.

Innovative Back Drop Out The back drop out is designed to encase the dogg third wheel in a very strong way (refer to Figure 1, Label C and Figure This allows the third wheel to interlock into and become part of the frame at a single point of contact. This is unique to the dogg UNLEASHED design.

Innovative Wider Rear Tyre A wider rear tyre provides for greater on-ground stability whilst maintaining a wheel stand (refer to Figure This is unique to the dogg UNLEASHED design.

Claims (1)

1. 20-JAN-2009 TUE 12:52 SMS ARTARMON 10299061780 P. 004/004 3 0 0* What is claimed is: S1. A skill and safety attachment fr a bicycle to allow the rider to perform and maintain a wheel stand, the bicycle having a frame and front and rear wheels with 0 axes of rotation, the attachment comprising: an omnidirectional wheel which is rotatably attached at one end of a support leg, the other end of the support leg being adapted to be attached to the frame of the IND bicycle where the axle of the rear wheel is connected, whereby the omnidirectional wheel would in use be located rearwardly of the rear wheel and Sbe raised from the ground in a normal riding position of the bicycle but may be Sbrought into engagement with the ground when a wheel stand is performed in -order to support the bicycle and prevent the bicycle from flipping backwards; 00 Sthe -support leg including two generally parallel rigid struts, with the O omnidirectional wheel disposed between the struts; the struts further including two sets of holes which permit the omnidirectional wheel to be attached to the leg in either a 'beginner' position or a 'pro' position, the 'pro' position enabling greater front wheel vertical lift of the bicycle when performing and maintaining a wheel stand. 2. Skill and safety attachment for a bicycle as set forth in claim I wherein the omnidirectional wheel and leg are complemented by an atypical seating angle, giving rear weight distribution for easier maintenance of a wheel stand.
