Abstract
Abstract In a bicycle having a main frame, a wheel support frame pivotally attached to the main frame by a swing arm, and a suspension system coupled to the swing arm and the wheel support frame, a device for inhibiting the operation of the suspension system consisting of a body having a first end and a second end, the first end being pivotally attached to the swing arm and the second end being configured to detachably engage the main frame, such that when the second end of the body is engaged with the main frame, movement of the swing arm is substantially restricted. In the bicycle, a method of inhibiting the operation of the suspension system consisting the steps of providing the body having the first end and the second end; mounting the first end such that the first end is pivotally attached to the swing arm; and, pivoting the body from a disengaged position to an engaged position such that when the second end of the body is engaged with the main frame, movement of the swing arm is substantially restricted.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
In a bicycle having a main frame, a wheel support frame pivotally attached to said main frame by a swing arm, and a suspension system coupled to said swing arm and said wheel support frame, a device for inhibiting the operation of said suspension system comprising: a body having a first end and a second end, said first end being pivotally attached to said swing arm and said second end having a flange being detachably engaged to said main frame, such that when said second end of said body is engaged with said main frame, movement of said swing arm is substantially restricted.
Claim 2
Dependent Claim
103 words
In a bicycle having a main frame, a wheel support frame pivotally attached to said main frame by a swing arm, and a suspension system coupled to said swing arm and said wheel support frame, a device for inhibiting the operation of said suspension system comprising: a body having a first end and a second end, said first end being pivotally attached to said swing arm and said second end having a flange being detachably engaged to said main frame, such that when said second end of said body is engaged with said main frame, movement of said swing arm is substantially restricted.
Claim 3
Dependent Claim
18 words
The inhibiting device in the bicycle as claimed in claim 1, wherein said flange has a concave surface.
Claim 4
Dependent Claim
25 words
The inhibiting device in the bicycle as claimed in claim 1, wherein said first end has a forked extension for mounting on said swing arm.
Claim 5
Dependent Claim
81 words
The inhibiting device in the bicycle as claimed in claim 1, wherein: said body further includes a first side and a second side, said first side configured to engage a spring member; and a cable having a first end detachably coupled to said second side of said body, such that when said first end of said cable is in a first position, said spring member is compressed and said second end of said body will be engaged with said main frame.
Claim 6
Dependent Claim
44 words
The inhibiting device in the bicycle as claimed in claim 4, wherein when said first end of said cable is in a second position, said spring member is uncompressed and said second end of said body will be substantially disengaged from said main frame.
Claim 7
Independent Claim
205 words
A method of inhibiting the operation of a suspension system of a bicycle having a main frame, a wheel support frame pivotally attached to said main frame by a swing arm, and a suspension system coupled to said swing arm and said wheel support frame, said method comprising the steps of: providing a body having a first end and a second end, said second end being configured to detachably engage said main frame; mounting said first end such that said first end is pivotally attached to said swing arm; pivoting said body from a disengaged position to an engaged position such that when said second end of said body is engaged with said main frame, movement of said swing arm is substantially restricted; and, wherein said body further includes a first side and a second side, said first side configured to engage a spring member; and a cable having a first end detachably coupled to said second side of said body, said pivoting step further including the step of: adjusting said cable, such that when said first end of said cable is in a first position, said spring member is compressed and said second end of said body will be engaged with said main frame.
Claim 8
Independent Claim
205 words
A method of inhibiting the operation of a suspension system of a bicycle having a main frame, a wheel support frame pivotally attached to said main frame by a swing arm, and a suspension system coupled to said swing arm and said wheel support frame, said method comprising the steps of: providing a body having a first end and a second end, said second end being configured to detachably engage said main frame; mounting said first end such that said first end is pivotally attached to said swing arm; pivoting said body from a disengaged position to an engaged position such that when said second end of said body is engaged with said main frame, movement of said swing arm is substantially restricted; and, wherein said body further includes a first side and a second side, said first side configured to engage a spring member; and a cable having a first end detachably coupled to said second side of said body, said pivoting step further including the step of: adjusting said cable, such that when said first end of said cable is in a first position, said spring member is compressed and said second end of said body will be engaged with said main frame.
