摘要： A bicycle hub has an axle and a hub shell rotatably disposed about the axle with a plurality of spoke fixing parts disposed at opposite ends of the hub shell. Each of the spoke fixing parts has a through hole having a small width section extending from a first side of a corresponding one of the spoke fixing parts and a large width section extending from a second side of the corresponding one of the spoke fixing parts such that an internal abutment is formed between the small and large width sections. The securing elements are removably disposed in the large width sections of the spoke fixing parts of the hub shell with each of the securing elements having a threaded bore that is aligned with and substantially equal to the small width sections of the spoke fixing parts of the hub shell.

摘要： A bicycle pedal assembly includes a pair of pedals and a pair of cleats. The cleats are configured and arranged to selectively cooperate with the right and left bicycle pedals such that two different release forces can be attained using a single pair of cleats. The pedal includes a body that rotates about a shaft and a front and rear clamping members are coupled to opposite ends of the pedal body. Also, the front and rear clamping members are preferably pivotally coupled to the pedal body.

摘要： A bicycle pedal assembly has a cleat releasably coupled to a pedal by a cleat engagement mechanism formed on an upper surface of its pedal body. The pedal body has a front end configured and arranged to include a sole guide portion that assists the rider in rotating the pedal body about its pedal shaft. In one embodiment, the sole guide portion is formed by a first concaved sole receiving recess located in a tip surface of the pedal body and a second concaved sole receiving recess located on the upper surface of the pedal body adjacent to the tip surface. Alternatively, the concaved sole receiving recesses can be replaced with either a pair of laterally spaced projections located on at the front end of the pedal body, or a V-shaped tip surface.

摘要： A magnetic device mounts on a flat spoke of a wheel. This magnetic device can comprise a magnet and a housing. The housing is coupled to the magnet, and has a spoke-receiving recess with a non-circular cross section, and at least one detent. The detent extends from the housing into the spoke-receiving recess to secure a flat spoke within the spoke-receiving recess via a snap-fit. The magnetic device communicates with a sensing device, which is adapted to be coupled to a portion of the bicycle that is adjacent to a wheel of the bicycle. A display unit, adapted to be mounted on handlebars of the bicycle, displays the speed information obtained from the sensing device. In a second embodiment, the housing is made of a more elastic material, and the detents become optional. In a third embodiment, the spoke-receiving recess of the housing has a projection that engages a concavity form in the connecting portion of the spoke. In a fourth embodiment, the spoke-receiving recess of the housing has a concavity that engages a projection form on the connecting portion of the spoke.
