1. A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire, the pressure sensing assembly comprising:
a housing defining a plane;
a pressure transmitting member coupled to the housing, the pressure transmitting member having a central portion offset from the plane in a first direction, the pressure transmitting member being an exterior surface of the pressure sensing assembly;
a sensing chamber defined by the housing and the pressure transmitting member;
an incompressible fluid disposed in the sensing chamber; and
a sensing element offset from the plane in a second direction opposite the first direction,
wherein the pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber,
wherein the housing includes a first housing portion and a second housing portion, the second housing portion including an aperture for receiving a power source, and
the first housing portion and the second housing portion are both at least partially external surfaces of the pressure sensing assembly.
