A bicycle handlebar shock absorbing assembly includes a core connected with the front fork of a bicycle and a first flat surface is defined in an outside of the core. A bead sleeve is mounted to the core and includes a second flat surface in which a plurality of rollers are embedded. A resilient member has an end rested on a top of the bead sleeve. A driving tube has a recess defined in a first end thereof and a second end of the driving tube is connected with a handlebar. A third flat surface is defined in an inner periphery of the recess. The resilient member and the bead sleeve are received in the recess, the rollers are in contact with the first and third flat surfaces. The core pushes the bead sleeve upward to compress the spring when shocks are transferred from the roads.
