摘要

The folding bike (1) has a head tube (10) arranged at an end of a frame rod (6) to receive a front wheel fork (11). A seat tube (21) is swung between a seat position and a couch position by a rotary bearing that is provided at another end of the frame rod. A rear wheel rocker (14) is supported at a fixed arm (22) of the frame rod. The seat tube comprises a nose structure that moves the rear wheel rocker from a running position (3) towards a sliding position of a front wheel (12) when the seat tube is pivoted from the seat position to the couch position.
