A seatpost assembly comprising
- a seatpost;
- and
- a saddle sensor assembly attached to the seatpost,
- the saddle sensor assembly comprising
- a load input configured to receive a load from a rider, and configured to be movable due to the load applied by the rider;
- a sensor support provided between the seatpost and the load input,
- the load input being separately formed from the sensor support and a saddle so that the load input is configured to be movable relative to the sensor support between a first position and a second position, the load input being movably and pivotally connected to the sensor support about a fixed pivot point to facilitate movement between the first and second positions, the load input being an upper surface configured to be positioned above a seat surface of the saddle in a case where the saddle sensor assembly is attached, the upper surface of the load input being movable between the first and second positions relative to the sensor support;
- the fixed pivot point being a pivot pin connecting a front end of the load input and a front end of the sensor support, the load input being connected to the sensor support through the opening in the saddle, the pivot pin being disposed at a front end of the saddle;
- a mount supporting the load input and the sensor support, and attached to the seatpost;
- and
- a sensor supported by the sensor support, wherein
- the sensor is configured to detect relative movement of at least one of the load input and the sensor support between the first position and the second position.
