Electronic shifting systems, mechanisms and methods of using and/or controlling the systems to operate a bicycle that allows front and rear gear changer mechanisms to be controlled with only two switches. The switches can be arranged so that each hand is only required to operate one switch to shift the bicycle.

A bicycle component control device includes a bracket, a hydraulic brake unit and either a mechanical shifting unit or electric control unit. The bracket has a gripping portion. The hydraulic brake unit is operatively mounted on the bracket and configured to operate a hydraulic brake device. The mechanical shifting unit or the electric control unit is operatively mounted on the bracket and configured to operate a bicycle device.

A bicycle component control device basically includes a bracket and a bicycle component operating unit. The bicycle component operating unit is disposed in an interior space of the bracket. The bicycle component operating unit includes an operating member protruding toward outside of the interior space. The bracket includes a plurality of bracket parts being separate pieces from each other and non-movably fixed to at least one adjacent one of the plurality of bracket parts that define the interior space. The plurality of bracket parts is further configured relative to each other such that a connecting seam formed on the bracket extends along at least three of a mounting surface, an upper surface, a lower surface, a first side surface and a second side surface of the bracket.

Embodiments herein relate to a wheelchair gearshift arrangement (10), which comprises an axle tube (20) and a pair of wheel attachment adaptors (30) inserted into a respective end (21, 22) of the axle tube (20). The wheel attachment adaptors (30) further includes a respective axle sleeve (40) adapted to receive and hold a respective wheel axle (51) of a respective complete wheelchair wheel (50). Each complete wheelchair wheel (50) having a respective wheel axle centric, axially translatable, gear change mechanism (52). One or more gear change actuators (80) are arranged within the axle tube (20) such that they are operative to selectively, upon user manipulation of an associated gear selector (60), axially translate the associated gear change mechanisms (52) of the respective complete wheelchair wheels (50). Such translation will affect a change of gear ratio between a push-rim (55) and wheel-rim (56) of each respective complete wheelchair wheel (50).

Multi-axis pivot assemblies for control sticks and associated systems and methods are disclosed herein. A multi-axis pivot assembly in accordance with an embodiment of the present technology can include, for example, an input shaft, a first axis output shaft coupled to the input shaft, and a second axis output shaft coupled to the input shaft via a series of linkages and pivoting joints. The first and second axis output shafts rotated about corresponding first and second fixed bearing sets to capture a first axis output and a second axis output. The series of linkages are configured to decouple first axis movement of the input shaft from second axis movement of the input shaft such that the second axis output is substantially independent of the first axis output.
