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 bicycle folding mechanism includes a frame, a stem, and a front fork. The frame includes a front tube at an end thereof. The stem is inserted into the front tube. The stem is connected and pivotal relative to the frame. The stem has an end, which is adjacent to the frame, connected with a connecting seat. The front fork includes at least one connecting end and at least one front end on opposite ends. The at least one connecting end is connected and pivotal relative to the connecting seat such that the front fork is pivotal relative to the connecting seat. The front fork is pivotal between a deployed position in which the at least one front end is positioned away from the frame and a folded position in which the at least one front end is positioned adjacent to the frame.
