ABSTRACT:
This invention is a bicycle torque detection apparatus for a bicycle having a pair of cranks each having a pedal, and a rotating shaft supporting the cranks to allow a user to step on the pedal to turn the cranks and drive a gear engaged with a chain. It comprises a detection section or rotating shaft consisting of magnetic alloy having magnetic anisotropy, the permeability of said detection section or rotating shaft being changed by torsional stress caused by the rotation of the cranks, and a coil unit disposed on the outer circumference of the detection section or rotating shaft to detect a change in the permeability of the detection section or rotating shaft.
