MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075580 A) filed by Ckanta Ltd on June 18, 2026, for A Bottom-Bracket Assembly For A Human-Powered Vehicle.
Inventor includes Ritchie, Andrew William.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: A bottom-bracket assembly for a human-powered vehicle (HPV), the HPV comprising a drive-side and a non-drive-side and a power output means attached to the drive-side of the HPV for conveying power to a road wheel. The bottom- bracket assembly comprises a hollow cartridge carrying in its bore a plurality of bearings to support a bottom-bracket axle which can revolve inside the bearings. The cartridge is mountable to a frame of the HPV. The bottom-bracket assembly further comprises a first mounting structure at a drive-side end of the cartridge. The first mounting structure has an elastic resistance to rotation in yaw and roll of the cartridge 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 forces which are not in balance about the first mounting structure such that the first mounting structure provides a fulcrum for said rotation of the cartridge. The bottom-bracket assembly further comprises a second mounting structure positioned axially nearer to the non-drive-side of the HPV than the first mounting structure when the cartridge is mounted to the frame of the HPV. The second mounting structure has a compliant resistance to the rotation in yaw and roll of the cartridge. The bottom-bracket assembly further comprises one or more sensors configured to sense radial displacement of the cartridge arising from said rotation of the cartridge about the fulcrum.
