PROBLEM TO BE SOLVED: To provide a bicycle frame which prevents a wire from being exposed to the outside of the bicycle frame and enables the wire to be easily arranged in the bicycle frame.SOLUTION: A bicycle frame 1 includes: a first frame part 10 extending in one direction X; and a second frame part 20 which is connected with the first frame part 10 and extends in the other direction Y intersecting with the one direction X. The first frame part 10 is formed with a first wire housing part in which a wire 4a is housed, and the second frame part 20 is formed with a second wire housing part communicating with the first wire housing part and in which the wire 4a is housed. Communication holes communicating with both of the first wire housing part and the second wire housing part are formed on an outer surface in a connection portion between the first frame part 10 and the second frame part 20.SELECTED DRAWING: Figure 1
