Abstract
A sensor assembly includes a shank shaped for mating with a socket in a head of a bolt about which a portion of a rear suspension of a bicycle pivots. A magnetometer (or a permanent magnet) is coupled to the shank. A permanent magnet with a north pole and a south pole (or a magnetometer) is positioned adjacent to the magnetometer (or permanent magnet) and pivotable relative thereto. A linkage couples the permanent magnet (or magnetometer) to the portion of the rear suspension that pivots about the bolt. The magnetometer senses changes in the magnetic field as the suspension pivots.

A sensor assembly for sensing pivoting motion of a rear suspension of a bicycle, the bicycle including a socket in a head of a bolt about which a portion of a rear suspension of the bicycle pivots, the sensor assembly comprising:
- a shank, the shank having a non-circular cross-sectional shape for mating with a socket in a head of a bolt about which a portion of a rear suspension of a bicycle pivots;
- a housing containing a sensor, the housing being rotatable relative to the shank;
- a permanent magnet coupled to the shank;
- the sensor sensing relative rotation between the housing and the shank by sensing changes in a magnetic field produced by the permanent magnet;
- a linkage coupled to the housing, the linkage being connectable to the portion of the rear suspension that pivots about the bolt.
