Abstract: System and method for detachable handlebars and fixing said handlebars onto a mount are presented. Specifically, the handlebars are independent the bicycle and mount; in some arrangements, the handlebar locking shaft may include a non-clamping connection that allows for the handlebars to attach to the bicycle quickly and easily and to prevent the handlebars from sliding, rotating, disengaging, or otherwise moving while a user is on the bicycle. The non-threaded assembly disclosed in accordance with the present invention may generally exploit several compression mechanisms to bias a series of keys into a locking position to secure the handlebars attachment to the bicycle or mount. Other embodiments are also included.
