A pair of upper and lower relatively rotatable collar members are mounted on the upstanding neck portion of a bicycle from which the handlebars supported and which is rotatable relative to the frame of the bicycle with the front fork assembly of the bicycle about an upstanding axis concentric with the neck portion. The collar members are slidable along and rotatable relative to the neck portion and interconnected against axial shifting. The frame of the bicycle includes a pull cable actuated rear wheel brake and the handlebar of the bicycle includes a shiftable pull cable actuator. A first pull cable section is operatively connected between the rear wheel brake and the lower collar member and a second pull cable section is operatively connected between the brake actuator and the upper collar member.
In combination with a bicycle including a frame having front and rear ends, a rear wheel journalled from said rear end and a front fork assembly journalled from said front end for angular displacement relative thereto about an upstanding axis and having a front wheel journalled therefrom, rear brake means operatively associated with said frame and rear wheel for releasably variably braking said rear wheel relative to said frame and including a brake operator movably mounted from said frame, first elongated motion transmitting means having first and second ends, said first end being attached to said operator and said second end being disposed adjacent said front fork assembly, said front fork assembly including an elongated handlebar support neck portion projecting upwardly and mounted from said front fork assembly for angular displacement therewith and disposed generally concentric with said axis, a rear brake operator mounted for shifting relative to said neck portion, second elongated motion transmitting means having first and second ends and the first end thereof attached to said actuator and the second end thereof disposed adjacent said neck portion, first and second upper and lower collar members slidably and rotatably mounted on said neck portion, rotatable relative to each other and interconnected against relative axial shifting, and means operatively connecting the second ends of said first and second motion transmitting means to said lower and upper collar members, respectively.
The method of modifying a bicycle for free spinning of the handlebar and front fork assembly thereof relative to the bicycle frame and wherein the bicycle is of the type including a frame from which a rear wheel is journalled, a rear wheel brake assembly mounted from the frame for actuation to adjustably brake the rear wheel, a front fork assembly journalled from the frame for rotation relative thereto about an upstanding axis, a front wheel journalled from the front fork assembly, an upwardly projecting handlebar supporting neck portion mounted from the front fork assembly for rotation therewith and disposed generally concentric with said axis and a brake actuator mounted on the handlebar and operatively connected to the rear brake assembly for actuation thereof through the utilization of a connecting pull cable assembly;
