An apparatus including a bicycle frame including a drive side chain stay. The drive side chain stay can include a drive side chain stay chamber, an inside chain stay cutout, an outside chain stay cutout; and a dropout. The drive side chain stay can be configured such that a chain of a bicycle including the bicycle frame can be inserted through the inside chain stay cutout, the drive side chain stay chamber, and the outside chain stay cutout without breaking the chain.

A bicycle includes a front wheel and a rear wheel and a frameset supported on the front wheel and the rear wheel. The frameset includes a main frame and a front fork rotationally coupled to the main frame. The main frame includes a top tube, a head tube rotationally supporting the front fork, a down tube coupling the head tube to a bottom bracket, a seat tube extending downward from the top tube and including a lower end spaced from the bottom bracket, a seatstay extending rearward from the lower end of the seat tube, and a strut member extending forward from the lower end of the seat tube and connecting the seat tube to the down tube.

A lever driven bicycle with synchronous drive ratio control is disclosed. The lever driven bicycle may include a pair of drive levers pivotable around an axis. The lever driven bicycle may also include a force applicator connected to each drive lever, each force applicator configured to receive an application of a force to rotate a drive wheel. The lever driven bicycle may further include a control mechanism connected to the pair of drive levers, the control mechanism configured to synchronously adjust a drive ratio of each drive lever.

A method for forming a bicycle frame component made of thermoplastic composite laminates has: a shell forming step: manufacturing multiple shells by compression molding; an overlapping step: overlapping two corresponding connecting margins of each two of the multiple shells to form an overlapping section of the two of the multiple shells and deploying a supporting unit within the multiple shells for supporting; a hot compressing connection step: heating and compressing the multiple shells to diffuse polymers of the multiple shells and to turn the multiple overlapping sections into multiple fusion areas for connection; a supporting unit removal step: removing the supporting unit disposed within the bicycle frame component.
