Abstract: A bicycle drive apparatus comprises a bicycle crankset, a bicycle transmission, a drive assistance electric motor, a crank variation determining sensor and a microcomputer. The crank variation determining sensor is arranged to determine a variation value related to rotation of the bicycle crankset. The microcomputer includes a shift command section, a limiting section, a determining section and a limitation cancelling section. The shift command section issues a shift command commanding the bicycle transmission to change gears. The limiting section limits an output of the drive assistance electric motor upon issuance of the shift command. The determining section determines completion of a gear shift operation upon the variation value being within a prescribed range. The limitation cancelling section cancels the limitation of the output of the drive assistance motor upon the determining section determining the completion of the gear shift operation.

Abstract: A bicycle wheel securing structure is basically provided with a bicycle fork, an adapter and a holding member. The adapter includes a first portion defining a maximum width of the adapter and a second portion extending axially from the first portion with the second portion being disposed in a hole in an axle support portion of the a bicycle fork. The second portion has an axial bore that is at least partially threaded. The holding member is attached to the axle support portion. The holding member is selectively movable between a retaining position to prevent rotation of the adapter with respect to the bicycle fork and a releasing position to permit rotation of the adapter with respect to the bicycle fork. The holding member remains attached to the axle support portion in both of the retaining and releasing positions.
