Problems solved by technology

However, such bicycles are not practical for driving into very soft ground surfaces where there is no hard support for the tires and the tires will sink into the surface and cause the rider to fall.

Embodiment Construction

[0024] Referring now to the drawings, and more particularly to FIG. 1, there is shown generally at 10 an all-terrain bicycle constructed in accordance with the present invention. The bicycle is comprised of a frame 11 having a front fork 12 and a rear fork 13. Shock absorbers 14 are secured to the front fork 12 as is well known in the art. A front wheel 15 and a rear wheel 16 are respectively connected to the front fork 12 and the rear fork 13. The front and rear wheels are provided with a central hub 15' and 16' respectively which are interconnected to the rims 15" and 16" by spokes 17' and 17", respectively.

[0025] The rear wheel 16 is provided with a sprocket set 18 connected to its hub 16' and driven by a drive sprocket 19 secured to the frame 11 beneath the seat 20, as is well known in the art. Foot engaging paddles 20 rotate the drive sprocket 19 and through its chain link connection 21, or other such belt-like drive connector, drives the sprocket set 18 to impart movement to t...

Abstract

An all-terrain bicycle is comprised of a bicycle frame having a front and a rear fork to which is removably secured a front and a rear wheel. Each wheel has a circular rim which is interconnected to the hub by spokes. The rear wheel has sprockets secured to the central hub and which is interconnected to a driving sprocket by a chain or other such belt-like drive connector. Each of the rims is provided with a surface engaging support shoes assembly to provide support of the bicycle on a surface. Such bicycles are particularly useful for riding on soft and also irregular surfaces which are deformable such as sand, snow or the like.

Description

[0001] The present invention relates to an all-terrain bicycle having wheels provided with a surface engaging support plate assembly connected to its rim making the bicycle particularly adapted for riding over soft and also irregular surfaces, such as sand, snow, etc.[0002] All-terrain motorized vehicles are known and are very popular nowadays. Also, the conventional bicycle has been modified and equipped with special shock absorbers and modified tires whereby the rider can drive over irregular terrain and not be subjected to the shocks imparted by such irregular terrain. These are commonly referred to as "mountain bikes" The wheels are still of the conventional construction whereby an inflatable tire is secured about the rims. However, these tires are larger in cross-section than the conventional touring bicycle and are provided with various types of thread formations to provide better surface engagement. These "mountain bikes" are popular for driving along rough trail surfaces suc...
