Abstract
A bike frame includes including a seat tube (10) for receiving a seatpost (2), a front portion comprising a top tube (13) connecting the seat tube (10) to a head tube (16), the seat tube (10), the top tube (13). The head tube (16) extends in a plane of symmetry of the bike frame (1). A rear portion has two chain stays (11a, 11b) and two seat stays (12a, 12b) arranged symmetrically relative to the plane of symmetry of the bike frame (1). The two seat stays (12a, 12b) are independent of each other and the two seat stays (12a, 12b) have a preform that is curved along at least one arc in a plane passing through the two seat stays, so as to enable the two seat stays to move away from or closer to each other under the action of a vertical load.
