摘要： A polygonal frame self-locking bicycle includes a head tube (13) mounting a wheel containing front fork (14), a down tube (16) rigidly connected between the head tube and a pedal crank housing (17), a seat tube (18) mounting a rear fork (19) and wheel (20) and rigidly connected to the crank housing and a top tube (12) locking with and demountable from at least one of the head and seat tubes. Preferably, a top tube end is key locked to the seat tube and the other end affixed to a clamping cylinder (22) around the head tube. Loosening of the clamping cylinder permits pivoting and unlocked top tube to open a space between the seat and head tubes. The demounted top tube forms a frame opening that can be leaned past a vertical pole (30) and the top tube remounted and relocked locking the frame about the pole.
