Abstract: A cycle driving device has a torque sensor, a crankset axle or a hub connected to a plate by a coupling, and a driving and measuring member having a first section secured in rotation with the crankset axle or hub, and a second section connected to the plate. A magnetic field source is supported by one of the sections. The coupling member incorporates a torque detection device. The first and second sections cooperate through an elastically deformable element. The torque detection device comprises a fixed magneto-sensitive element that measures a magnetic field according to the relative angular position of the first and second sections, and is capable of converting the magnetic field into an electrical signal. The magnetic field measurement is performed at a single axial position in the periphery of the first and second sections independently of the rotation of the crankset axle or hub.

Abstract: A locking device includes a mobile locking member, movement of which can be prevented by a blocking member interacting with a motorized lever, where the motorized lever is capable of rotational movement about an axis with respect to the supporting structure, the centre of gravity of the lever lying on the axis, the lever being kept in a determined stable position and without rigid mechanical contact of the lever with the supporting structure apart from its axis of rotation.
