A variable stem for a human-powered vehicle basically includes a head tube mount, a handlebar mount, a stem body, a positioning structure and a controller. The stem body couples the handlebar mount to the head tube mount. The stem body is configured to be moved between a first position and a second position. The handlebar mount is disposed at a different location with respect to the head tube mount with the stem body in the first position as compared to the stem body being in the second position. The positioning structure is configured to selectively position the stem body between a first position and a second position. The controller is configured to control the positioning structure while the human-powered vehicle is in a driving state.

A foldable bicycle contains: a front frame, a rear frame, and a folding device. The front frame includes a front fork connected on a front wheel, and the rear frame includes a rear fork connected on a rear wheel and includes a seatpost coupled with a connection post and a saddle. The folding device is rotatably connected between the front frame and the second frame. The front fork has a sole column, the front wheel is inserted through a hub by using a hollow hub shaft to connect with the sole column, and the hollow hub shaft has a first connection element defined in a central portion thereof The rear wheel has a second connection element extending outward from a central portion thereof so as to fit with the first connection element after folding the front wheel and the second wheel.

Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when traveling. The traveling apparatus includes a driving unit configured to drive at least one of the front wheel and the rear wheel, an adjusting mechanism including a rotation part configured to rotate a front wheel supporting member and a rear wheel supporting member in relation to each other, the adjusting mechanism being configured to adjust a wheel base length between the front wheel and the rear wheel by an action of the user being transmitted, thereby changing an angle formed by the front wheel supporting member and the rear wheel supporting member, and a control unit configured to control the driving unit based on a parameter, the parameter changing in conjunction with the wheel base length.
