Description

A REAR MUDGUARD ASSEMBLY OF A TWO- WHEELED VEHICLE AND METHOD THEREOF

FIELD

The present disclosure relates to the field of accessories of a two-wheeled vehicle. More particularly, the disclosure is related to the rear mudguard assembly of the two wheelers.

BACKGROUND

The background information herein below relates to the present disclosure but is not necessarily prior art.

Presently, maintaining and servicing of parts of a bike that are placed underneath a seat or mud guard is a difficult and tedious task. Also while washing the bike one has to bend down to access the inner-lower portion of the rear mudguard. As a result mud keeps on accumulating on the inner side of the mudguard. This increases the weight and may also result in rusting of metal components of the mudguard.

In case of two wheelers having a single seat, the mudguard cannot be extended out of vehicle frame from under the seat as it is done in normal two-seater motorcycles. In some motorcycles, an additional hugger is attached to swing arm. This hugger does not house the taillight assembly and thus it can be bolted on and off when required to service the rear wheel. However, when a rear mudguard not only has to house a taillight assembly, but also has to perform the function of the hugger it is not possible to completely remove the mudguard from the swing arm, all the time, as the electric connections will cause difficulty. Incorporating a mudguard which acts as a hugger and also has tail lamps mounted thereon is a challenging task. It is necessary to find a suitable arrangement to mount the mudguard.

Thus, there is a need of a rear floating mudguard assembly for a two wheeler that will ameliorate the drawbacks mentioned above. OBJECTS

Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows. An object of the present disclosure is to ameliorate one or more problems of the prior art or to at least provide a useful alternative.
