Abstract: A folding vehicle includes first and second front frame extension sections pivotal about a first pivot axis. A head tube spaces from the first pivot axis at a first distance. A front rolling device is pivotal about a second pivot axis and has a radius. The first distance is smaller than the radius. A rear rolling device is pivotal about a third pivot axis. The front frame extension in a folded position thereof includes the first, second and third pivot axes not aligned with one another, and the second and third pivot axes disposed on a phantom plane, as well as the first pivot axis offsetting from the phantom plane and disposed on a first side of the phantom plane that is adjacent to the second front frame extension section.

Abstract: A folding handlebar mechanism includes a steering tube, a stem assembly mounted on the steering tube, two handlebars rotatably and slidably mounted into two distal ends of the stem assembly, a repressed member abutted against the stem assembly, and a positioning assembly. The positioning assembly is operable between a tighten mode and a loose mode to cause the two handlebars to be selectively rotatable and slidable with respect to the two opposite ends of the stem assembly.

Abstract: A foldable bicycle has a front frame, a main frame, a rear frame and a driving device. The front frame has a front fork device with a front fork and a front wheel rotatably connected to the front fork. The main frame is connected to the front frame and has a front arm, a connecting device and a rear arm. The front arm has a front pivot rod. The connecting device is pivotally connected to the front arm. The rear arm is pivotally connected to the connecting device and has a rear pivot rod. The rear frame is rotatably connected to the main frame and has a rear fork device with a rear fork and a rear wheel rotatably connected to the rear fork. The driving device is mounted on the main frame to drive the rear wheel to rotate relative to the main frame and the front frame.

Abstract: A folding device includes a main body, two connecting members respectively pivotally connected to the main body, and a locking assembly. Each connecting member includes an engaging portion. The locking assembly includes first and second hooking members, a lever, and an axial member. The first hooking member and the lever are pivotally connected to the main body. The axial member is inserted through the main body, the first hooking member and the lever. The second hooking member is pivotally connected to the lever. The first hooking member includes a first hooking portion, and the second hooking member includes a second hooking portion. The lever is pivotable with respect to the main body between locking and releasing positions.
