bicycle pedal gauge

Abstract

For example, a bicycle pedal force gauge with excellent detection accuracy and mechanical strength, and a structure that is easy to miniaturize, is provided. For example, a bicycle pedal force gauge (1) includes: a bearing (102); a shaft (S); a retainer (101) having a retaining portion (110) for retaining the bearing (102) and a deformable surface (101a) extending radially; and a plurality of strain sensors (103s), the plurality of strain sensors (103s) including: a first strain sensor (103s1) mounted on a first portion (101a1) of the deformable surface (101a); a second strain sensor (103s2) mounted on a second portion (101a2); and a third strain sensor (103s3) mounted on a third portion (101a3), the plurality of strain sensors (103s) being arranged circumferentially, the second portion (101a2) and the third portion (101a3) being deformed to a greater extent than the first portion (101a1).
