ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a bicycle wheel, more particularly to a bicycle wheel with V-shaped spokes.
2. Description of the Related Art
FIG. 1
illustrates a conventional bicycle wheel
1
disclosed in U.S. Pat. No. 4,930,843. The bicycle wheel
1
includes a rim
101
, a hub
103
, and four angularly spaced apart spokes
102
interconnecting the rim
101
and the hub
103
. Since the spokes
102
are all connected to a middle portion of the hub
103
, a much higher stress will act on the middle portion of the hub
103
than on the remaining portion of the hub
103
when the bicycle wheel
1
moves over the ground. As a consequence, the middle portion of the hub
103
tends to break after a period of use.
FIG. 2
illustrates another conventional bicycle wheel
2
which includes a rim
201
, a hub
202
, and a plurality of angularly spaced apart rod-like spokes
203
interconnecting the rim
201
and the hub
202
. The bicycle wheel
2
is disadvantageous in that assembly thereof is laborious and time-consuming.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a bicycle wheel having V-shaped spokes that are capable of overcoming the aforementioned drawbacks.
Accordingly, the bicycle wheel of the present invention comprises: an annular rim having an annular base wall; a hub shell surrounded by the annular base wall, defining a rotating axis of the annular rim, and having two opposite ends that are disposed at two opposite sides of the annular rim; and a plurality of unitary V-shaped spokes equiangularly spaced apart and extending from the hub shell to the annular base wall, each of the V-shaped spokes having a tip end that is connected to the annular base wall, and two arms that are joined at and that diverge from the tip end, and that have distal ends which are distal from the annular base wall, which are respectively connected to the opposite ends of the hub shell, and which are angularly offset from each other.
