Abstract

A folding bike designed such that when the bicycle is folded, the front and rear frame structural members bypass each other in a non-overlapping manner except at folding and fastening positions usingan axis of rotation at or near the seat tube, wherein the folding bicycle maintains a rigid riding position using an innovative fastening mechanism positioned to fasten by actuation of a member located not above the uppermost surface of the front frame, and which may be equipped with primary and secondary retention wherein the secondary retention may automatically engage when the bike is unfoldedto the operative riding position.

Description

technical field [0001] The present invention relates to a folding bicycle with folding on or near the seat tube, wherein the front structural frame member and the rear structural frame member pass over each other during folding and do not overlap except in the folded and fixed positions, the folding bicycle A novel mechanism is used to lock the front and rear frames together in an operative riding position. Background technique [0002] To date, many folding bicycles have been designed that insert a hinge member into a cut main tube near the middle of the bicycle that both hinges and locks the bicycle in the riding position. These bikes are often not strong and require many folding steps for a bike that is complex to fold and weak in structure. To date, the strongest folding bicycles are those that do not destroy structural members, and instead fold around concentric tubes located at or near the seat tube, such as in U.S. Patent No. 4 448 437, No. 4 900 047 Bicycles such a...
