<p>A folding bicycle frame comprises a fordable front segment and a foldable rear segment. The front segment is a front arm (2), and the rear segment is an intermediate arm (3). A rear end of the front arm (2) and a front end of the intermediate arm (3) are hinged together at one side; a locking device (1) is provided at the other side. The locking device (1) comprises a handle (11) and a fixing rod (15), and the handle (11) is hinged on a fixing shaft (16) provided on one segment of the folding bicycle frame and protrudes from the folding bicycle frame; the handle (11) is provided with a mandrill (17), and a front end of the mandrill (17) can resist against the fixing rod (15) provided on the other segment of the frame and the fixing rod (15) is parallel to the fixing shaft (16). The folding bicycle frame of the present invention more complies with user's habit, is convenient to operate and simple in structure; the locking device (1) will not interfere with the chain wheel, which is more practicable.</p> |
