Abstract: A tubular handlebar includes an internal peripheral surface and a stem head with a mounting system for a mobile device. The tubular handlebar includes a open end, a closed end, at least one speaker unit embedded into at least one through hole of the internal peripheral surface, and a bass reflex system to enhance the acoustic characteristics of the sound generated by the at least one speaker unit. The tubular handlebar has a sound box affixed to the internal peripheral surface of the tubular handlebar and housing a rear part of the at least one speaker unit. The bass reflex system includes a bass reflex duct connecting the sound box with the first end. The mounting system further includes a first connector to electrically connect the mobile device to a second connector. The second connector can be detached or reattached to the at least one speaker unit.
