摘要： A crankset assembly to be mounted on a bicycle includes at least one right-hand bearing for mounting a crankset shaft and a force sensor positioned around the outer ring of the bearing. The force sensor includes a peripheral portion, a central portion, and a top frame connecting a top section of the peripheral portion to a top portion of the central portion. The frame is positioned at a diameter oriented along an axis (Y′). The axis (Y′) makes an angle (φ) of between 10° and 30° with the vertical axis (Y) and the top frame is positioned behind the vertical axis (Y).

摘要： An electric assist device for a bicycle comprising a shaft coupled in rotation with a pair of cranks and being able to be rotated in a positive direction by an electric motor, a connection mechanism being placed between the motor and the shaft, which connection mechanism has at least three distinct states. The states includes State 1, termed assist state, in which the motor transmits a torque to the shaft via a drive part which rotates at the same speed as the shaft, State 2, termed freewheel state, in which the rotation of the shaft in the positive direction is greater than that of the drive part, and State 3, termed disconnection state, in which a rotation in the positive direction or in the negative direction of the shaft cannot cause the motor to rotate.

摘要： An assist device for a bicycle includes a motor, a step-down gear, a free wheel, and a shaft which rotates as one with a right crank and a left crank. The motor transmits an assist torque to the shaft by m the free wheel. The device is designed to be received inside a pedal assembly casing. The shaft is rotatably mounted relative to the casing by two ball bearings. The free wheel includes a plurality of pieces which are placed between the motor and the shaft. The device also includes a torque transmission ring which allows one of the pieces of the free wheel to be secured to the shaft or to one of the cranks. The transmission ring is at least partially placed under one of the two ball bearings.
