1. Rear suspension device for a bicycle, wherein said device comprises:
(a) a first pivot having a first axis of rotation, a second pivot having a second axis of rotation, and a third pivot having a third axis of rotation;
(b) a first axial compression shock absorber;
(c) a linkage unit;
(d) a first sensor unit; and
(e) a first magnet
wherein
said first axis of rotation, said second axis of rotation and said third axis of rotation are parallel;
said first axial compression shock absorber comprises a first end and a second end, wherein said first end is attached to said first pivot and said second end is attached to said second pivot; and
said linkage unit is attached to said second pivot and said third pivot and rotates about said second axis of rotation and said third axis of rotation; characterized in that
said first sensor unit is located on a surface of said linkage unit and comprises at least one Hall-effect sensor located in a plane perpendicular to the third axis of rotation, wherein each Hall-effect sensor is located at a distance d1 from said third axis of rotation;
said first magnet is:
a cylindrical or cylindrical shell magnet having an axis of rotational symmetry which is perpendicular to the parallel faces thereof; or
a prism-shaped magnet comprising two polygonal parallel faces and an axis of rotational symmetry which is perpendicular to said parallel faces;
wherein the direction of the magnetic moment of said first magnet is perpendicular to said axis of rotational symmetry, wherein said first magnet is attached to said third pivot;
wherein there is a distance d2 between said first sensor unit and said first magnet, and wherein:
d1 is between 0.1 mm and 50 mm; and
d2 is between 0.01 mm and 50 mm
the third axis of rotation and the axis of rotational symmetry of said first magnet are aligned; and
said first magnet is embedded in said third pivot, and the face of said magnet which is closest to said first sensor unit is flush with the end surface of said third pivot.
