Scooter with a chassis, at least one front wheel, at least one rear wheel and a handlebar, wherein the handlebar is positively connected to the chassis, wherein a section of the handlebar forms a swivel joint with a section of the chassis or with a section attached to the chassis, which allows the handlebar to rotate relative to the chassis, so that the handlebar can be moved back and forth between a ready-to-run position and a transport position, wherein a joint gap is present between surfaces facing each other or surface sections of the handlebar and the chassis section or the section attached to the chassis wherein either the chassis or the section attached to the chassis or the section of the handlebar comprises a locking element which can be moved back and forth between a retracted and an extended position, wherein the locking element does not protrude into the joint gap in the retracted position to allow rotation of the handlebar relative to the chassis and wherein the locking element protrudes into the joint gap in the extended position, so that the chassis or the section attached to the chassis interacts with the section of the handlebar to block the rotation of the handlebar relative to the chassis, wherein the chassis or the handlebar is connected to an actuating arrangement for the locking element wherein the actuating arrangement comprises an actuating element which can be actuated by a user, and wherein the actuating arrangement is arranged to move the locking element from the extended position to the retracted position when the actuating element is actuated by a user, characterized in that the actuating arrangement and the locking element are situated on opposite sides with respect to the joint gap. wherein the handlebar is positively connected to the chassis, wherein a section of the handlebar forms a swivel joint with a section of the chassis or with a section attached to the chassis, which allows the handlebar to rotate relative to the chassis, so that the handlebar can be moved back and forth between a ready-to-run position and a transport position, wherein a joint gap is present between surfaces facing each other or surface sections of the handlebar and the chassis section or the section attached to the chassis wherein either the chassis or the section attached to the chassis or the section of the handlebar comprises a locking element which can be moved back and forth between a retracted and an extended position, wherein the locking element does not protrude into the joint gap in the retracted position to allow rotation of the handlebar relative to the chassis and wherein the locking element protrudes into the joint gap in the extended position, so that the chassis or the section attached to the chassis interacts with the section of the handlebar to block the rotation of the handlebar relative to the chassis, wherein the chassis or the handlebar is connected to an actuating arrangement for the locking element wherein the actuating arrangement comprises an actuating element which can be actuated by a user, and wherein the actuating arrangement is arranged to move the locking element from the extended position to the retracted position when the actuating element is actuated by a user, characterized in that the actuating arrangement and the locking element are situated on opposite sides with respect to the joint gap.
