Abstract: Tool-free bicycle components include a pedal assembly with pedals shipped in “folded” positions and rotated by hand into locked “open” positions for riding. A locking member nests in an axle notch to rotationally lock the pedals in place. A stem-fork assembly includes a fork unit having a fork post with a slidable compression ring covering a spring-biased stem locking member. The fork post is inserted into a stem tube of a stem unit, pushing the ring down and exposing the stem locking member, which can then “snap” into the stem tube to lock the fork unit with the stem unit. A training wheel assembly includes a mounting unit having a spring member with a bendable engagement end. When a wheel support with engagement slot is inserted into the mounting unit, the spring member snaps into the engagement slot to lock the training wheel support in place.

Abstract: A front end assembly that simplifies assembling of bicycles includes a threaded center bolt, a stem body, a stem tube, a frame head tube, and a fork steering tube with a wedge immovably fixed therein. The wedge includes a stem interface that complementarily fits with the stem tube to rotationally align the fork, and a bolt interface that engages the center bolt. The steering tube is inserted into the head tube from the bottom, and the stem tube is inserted into the head tube from the top. The center bolt threadably engages the bolt interface of the wedge to secure components together. The position of the wedge within the stem tube vertically aligns the stem body with respect to the fork steering tube. Automated alignment and tensioning eliminates much guesswork, and the assembly process is shortened.

Abstract: A coaster-style hub functions as a freewheel and accommodates a 9 tooth sprocket. A throw out bearing is used to allow the clutch to spin freely when the driver and sprocket are rotated in a backward direction. The driver and sprocket can be formed as a single piece.
