A bottom-bracket assembly for a human-powered vehicle (HPV) comprises a hollow cartridge 120 carrying in its bore a plurality of bearings 105, 106 supporting a bottom-bracket axle. The bottom-bracket assembly further comprises a first mounting structure 1103 at a drive-side end of the cartridge 120. The first mounting structure 1103 has an elastic resistance to rotation in yaw and roll of the cartridge 120 relative to the frame of the HPV that is insufficient on its own to prevent said rotation when the bottom-bracket axle is subjected to transverse pedalling forces such that the first mounting structure 1103 provides a fulcrum 123 for said rotation of the cartridge. A second mounting structure 1104 is positioned axially nearer to the non-drive-side of the HPV than the first mounting structure 1103. The second mounting 1104 structure has a compliant resistance to the rotation of the cartridge 120. One or more sensors are configured to sense radial displacement of the cartridge arising from rotation about the fulcrum 123.
