ABSTRACT:
A scooter includes a main frame, a head tube mounted on the main frame, two side plates extending from the head tube and each having a first locking slot and a second locking slot, a handlebar stem mounted on the head tube, a mounting sleeve mounted on the handlebar stem, a locking tube movably mounted on the mounting sleeve and having two locking blocks each locked in the first locking slot or the second locking slot of the respective side plate, and a rotation tube mounted on the mounting sleeve and abutting the locking tube. Thus, the rotation tube can be rotated to move the locking tube relative to the head tube so as to lock or unlock the handlebar stem so that the user only needs to rotate the rotation tube to expand and collapse the handlebar stem easily and quickly.
