Abstract:
A bicycle pedal unit comprises a central body (2) associable with a tube of a bicycle frame; two pedal cranks (3, 4) connected to opposite ends (2a) of the central body (2); two pedals (5, 6), each connected to a respective pedal crank (3, 4); the angular position of at least a movable pedal crank (3) is adjustable relative to the other pedal crank (4), which is fixed.
Abstract:
An automatic pedal for bicycles comprising a main body provided with means for its pivoting along an axis to a pedal crank, the main body comprising a compartment arranged to abuttingly house a first portion of a cleat associated with a shoe of a cyclist, and a coupling element pivoted to the main body and spring loaded, adapted to cooperate with a second portion of said cleat to removable fix, together with said compartment, the cleat to the main body, in which said compartment comprises at least one first and one second seat arranged to alternatively abuttingly receive said first portion of the cleat, the first seat being closer to the axis of said pivotal means than the second seat, such that the cyclist is able to choose where to abuttingly position the cleat, hence adjusting the position of the shoe relative to the pivotal axis.
Abstract:
Bicycle having disc brakes, transmission device including transmission element rotatably integral with drive wheel and coaxial thereto, frame with front and rear forks; rotatable removable support for front free wheel hub and rear drive wheel hub respectively at two ends of the arms of each fork, the support including a tie-rod in coaxial through-hole in the hub and holes at each fork arm free end, the tie-rod, when tensioned, allowing holding the wheel on the corresponding fork. The brake with disc and caliper on at least one side of at least one wheel. The disc coaxial with the relative wheel, the caliper with pads fixed to the corresponding arm. The discs supported rotatably, by the same arms. Elements for establishing a positive-locking fit allowing rotatably connecting the relative disc with the relative wheel hub when the tie-rod is tensioned and nullifying the positive-locking fit when the tie-rod is released.
Abstract:
Bicycle operated by transmission device including transmission element rotatably integral with drive wheel and coaxial thereto, and a frame with a front and rear fork; rotatable removable support at the two ends of the arms of each fork, for the hub of a front free wheel and a rear drive wheel respectively, the support including a tie-rod received in a coaxial through-hole made in the hub and in relative holes made at the free end of each arm of the relative fork. The tie-rod, when tensioned by appropriate means, allows holding the relative wheel in position on the corresponding fork. The transmission element supported rotatably by one of the arms of the rear fork. A positive-locking fit rotatably connects the transmission element with the rear wheel hub. The above-mentioned positive-locking fit established when the tie-rod is under tension and nullified when the tie-rod is released.
