Rear suspension device for a bicycle with three pivots, each with an axis of rotation an axial compression shock absorber, a linkage unit, a sensor unit and a magnet. The axes of rotation are parallel to each other and the axial compression shock absorber has a first end attached to the first pivot and a second end attached to the second pivot. The linkage unit is attached to the second pivot and the third pivot and rotates about the second and third axis of rotation. The sensor unit is on a surface of the linkage unit and comprises a Hall-effect sensor located in a plane perpendicular to the third axis of rotation and located at a distance d1 from the third axis of rotation. The first magnet is: a cylindrical or cylindrical shell magnet having an axis of rotational symmetry which is perpendicular to the parallel faces thereof; or a prism-shaped magnet comprising two polygonal parallel faces and an axis of rotational symmetry which is perpendicular to said parallel faces. The direction of the magnetic moment of the first magnet is perpendicular to said axis of rotational symmetry, and the first magnet is attached to the third pivot. The third axis of rotation and the axis of rotational symmetry of said first magnet are aligned. A distance d2 between said sensor unit and said magnet, and d1 is between 0.1 mm and 50 mm and d2 is between 0.01 mm and 50 mm.

A shock absorber includes a hollow cylinder body extending in an up-down direction, a rod pipe located on an axis of the cylinder body, provided to be relatively movable in an axial direction of the cylinder body with respect to the cylinder body, and provided in a form of receiving a force in the axial direction, a rod-shaped support body extending inside the rod pipe with an upper end fixed, a stroke sensor including a coil and a conductor provided to be able to detect relative displacement of the rod pipe with respect to the support body, and a hollow intermediate member provided between the inner peripheral surface of the rod pipe and the support body to allow movement in the axial direction.

An activity tracker includes a device that includes a sensor component, a radio, and a mounting member. The sensor component is configured to obtain bicycle route information based on information from one or more sensors.

A drive assistance device (24) for a saddle type vehicle (1) includes a ride sensor (37) configured to detect a ride attitude of a rider (J), a vehicle body behavior generating part (25) configured to generate a behavior on a vehicle body by a prescribed output, and a controller (27) configured to control driving of the vehicle body behavior generating part (25), and wherein, when the vehicle body behavior generating part (25) is actuated regardless of the operation of the rider (J), the controller (27) firstly controls the vehicle body behavior generating part (25) such that a low output that is lower than a predetermined original target output is generated as a predictive action, and sets an output value after that according to a change of detection information of the ride sensor (37) generated by the low output.

A straddled vehicle includes a body frame, a seat, a battery case storing a battery and inertial measurement unit, a drive wheel. The battery case is provided such that its bottom portion protrudes toward the position between the rear suspension and the rear wheel. The inertial measurement unit is fixed to the bottom portion of the battery case at a position above the inertial measurement unit. The bottom portion of the battery case is located in a space other than a space in which the rear suspension and the drive wheel are positioned when the rear suspension is in a most contracted state due to absorbance of shock. At least the battery and the inertial measurement unit partially overlap each other in a plan view of the vehicle.
