A slope sensitive pitch adjustor for a bicycle seat includes a rotatable seat support, a gravity sensor mounted thereto, a means for rotating the rotatable seat support, and an automated controller configured to drive the rotating means in response to an acceleration signal received from the gravity sensor. The automated controller stores data representing an initial condition of a pitch angle of the rotatable seat support with respect to horizontal and executes a control algorithm to maintain the initial condition when the bicycle is ridden over changing gradients.

An optical sensor disposition structure for a saddle riding vehicle includes an optical sensor, and an airflow guide member disposed in front of a head pipe and configured to cover a front section of a vehicle body and in which an introduction port configured to guide traveling air rearward is formed, wherein the optical sensor overlaps the introduction port when seen in a front view.

A saddle-riding type vehicle includes: a vehicle body frame; a swing arm supported in a swingable manner with respect to a pivot frame of the vehicle body frame; and a rear suspension in which a link arm supported by the swing arm and the pivot frame are coupled, and damping is controlled by a hydraulic oil. In addition, the saddle-riding type vehicle includes: a sub-tank provided in the rear suspension and storing the hydraulic oil; and a detection sensor that detects behavior of a vehicle body while traveling. Moreover, in a top view of the saddle-riding type vehicle viewed from above, the sub-tank and the detection sensor are disposed so as to overlap with each other.

A vehicle includes a frame, a passenger presence sensor mounted thereto, and a seat assembly removably connected to. The seat assembly includes a driver seat disposed on the frame and a passenger seat disposed on the frame rearward of the 5 driver seat, at least the passenger seat being selectively disposed on the frame. A rigid passenger presence responsive member (PPRM) is retained in the passenger seat and movable with respect to the frame between at least a first position and a second position responsive to a weight of a passenger seated on the passenger seat. The PPRM is coupled to the passenger presence sensor in at least one of the first and 10 second positions, the passenger presence sensor is thereby configured to detect a presence of the passenger. Removable passenger seats for a vehicle are also disclosed.

A method for ascertaining the steering angle of a one-track vehicle, in which: with a frame sensor system attached at a first location on the frame of the vehicle, the first frame accelerations occurring there and first frame rotation rates of the two-wheeler are each ascertained in three first spatial directions, with a steering system sensor system attached at a second location of the steering system of the vehicle, the steering system accelerations of the two-wheeler occurring there are ascertained in three second spatial directions, based on the ascertained first frame accelerations and first frame rotation rates, second frame accelerations at the location of the second steering system sensor system in the three first spatial directions are calculated based on a mathematical relationship, and based on the calculated second frame accelerations and the ascertained steering system accelerations, the steering angle of the vehicle is ascertained.

The present disclosure is directed to lean angle indication for motorcycles. The disclosure provides a motorcycle lean angle indication device that is operationally configured to be attached to a motorcycle and contact a surface that a motorcycle is traveling upon when the motorcycle realizes a target lean angle when executing a turning maneuver.

A two-wheel vehicle includes a frame and a metallic side stand, rotatable within a bracket attached to the frame. The metallic side stand is rotatable between a first position that supports the two-wheel vehicle when parked and a second position substantially adjacent the frame. The two-wheel vehicle also includes an inductive sensor attached to the two-wheel vehicle and connected to detect at least one position of the metallic side stand and a circuit connected to receive an output from the inductive sensor and to provide a signal that reflects the position of the side stand.

A sensor system is able adjust control location and the type of controls based on the positioning of a user's hands. The sensor system is adapted to detect the positioning of a hand or body part and compensate for the changing positions of the hand or body part. When the positioning of the hand or body part changes, the controls that are able to be activated by the hand or body part also change and adapt to the location where the controls are activated, providing accessible and/or contextualized controls.

Disclosed are a foot plate for a self-balancing scooter, and a self-balancing scooter. The foot plate (1) for a self-balancing scooter comprises a main body (10) and touch control portions (11). A front side and a rear side of a lower surface of the main body are both connected to the touch control portions, which protrude downwards and are used to trigger a sensor on a self-balancing scooter. The touch control portions at the front side and the rear side of the lower surface of the foot plate for a self-balancing scooter are capable of directly triggering corresponding sensors. The foot plate is applicable to twisting scooters having a left scooter portion and a right scooter portion which are capable of twisting relatively. No additional components are required, and users just need to install the foot plate on a self-balancing scooter. The foot plate has a simple and logic structure, and a self-balancing scooter adopting the foot plate is compact in overall structure, easy to install, convenient to operate, better in control performance, and longer in service life.
