A motorized bicycle training wheel system for training people to ride a bike without pedaling includes a pair of motorized training wheels each comprising an attachment bracket, a motor, and a wheel. The attachment bracket has an attachment aperture to receive an axle of a bicycle. The motor has a motor housing coupled to a lower portion of the attachment bracket. The wheel is coupled to a drive shaft of the motor. A battery is in operational communication with the motor of each of the pair of motorized training wheels and coupled to a frame of the bicycle. A throttle is in operational communication with the battery and the motor of each of the pair of motorized training wheels and coupled to a handlebar of the bicycle.

A position sensor of the present invention includes: a magnet that moves together with a moving body; a magnetic sensor that detects a magnetic flux generated by the magnet; and a detector that detects an anomaly of the magnetic sensor based on a detection value detected by the magnetic sensor. The magnetic sensor is set so as to detect the detection value taking a value on a locus preset in accordance with a position of the moving body, and the locus is set so that a change rate of the detection value corresponding to change of the position of the moving body differs for each of a plurality of sections set within a movement range of the moving body. The detector detects the anomaly of the magnetic sensor based on a relation between the detection value and a comparison value that is a value corresponding to the locus.

A set of handlebar grips for use with an electric motorbike is provided. The set of handlebar grips comprising a first handlebar grip having a first differentiating characteristic and a second handlebar grip having a second differentiating characteristic. The first differentiating characteristic differs from the second differentiating characteristic. One of the first handlebar grip and second handlebar grip is rotatable to power the electric motorbike.

This invention refers to a vehicle specifically designed to be used as transportation during a golf game. It is an individual transportation vehicle that includes three main support structures: one front structure, one intermediate structure, and one rear structure, where a couple of tires are located, as well as a support mechanism to keep the vehicle standing, a leveling clamping mechanism for a bag for the golf clubs, and many accessories that allow the driver to safeguard and access to several useful elements during the game, such as the scorecard, the golf balls, the support tees, mobile devised and even drinks, all of them safeguarded in a cavity underneath the seat. The vehicle is designed to meet with the regulations that rule vehicles authorized to move within the terrain of a golf course.

An accelerator position sensor according to the present invention is held inside a throttle grip of a vehicle rotationally operated by a driver. The accelerator position sensor includes: a magnet extended along a rotation axis of the throttle grip and configured to rotate in conjunction with the throttle grip; a magnetic detection unit arranged so as to face a predetermined face of the magnet; and a magnetic body arranged so as to face another face that is different from the predetermined face of the magnet. On the predetermined face and the other face of the magnet, respectively, mutually different numbers of magnetic poles are magnetized along a rotation direction of the magnet.

Controller and control method for improving operability at a time when a brake force that is retained in hill-hold control is reduced. A control section for executing the hill-hold control that retains the brake force on an inclined road surface is provided. The control section cancels retention of the brake force in the case where it is determined on the basis of a detection signal of a first detection mechanism that a first operation section for operating a brake mechanism is operated when the brake force is retained in the hill-hold control.

A system for measuring the rotation of a throttle knob of a vehicle such as a motorcycle, snowmobile, personal watercraft or the like is disclosed, including a knob fitted onto a handlebar and capable of rotating around it. The knob has a magnet, provided for a fixed sensor suitable to detect the angular movement of the magnet following a rotation of the knob for the vehicle throttle control. The magnet has two sectors (N, S) with opposite polarity and different length, with the magnet therefore having asymmetric polarities.

A plurality of control maps respectively corresponding to a plurality of lever operation amounts are stored in a storage device. Each control map defines a driving force to be output from an electric motor such that the driving force corresponds to an accelerator operation amount and a vehicle speed. A control device uses a control map corresponding to an actual lever operation amount among the plurality of control maps and thereby calculates the driving force to be output from the electric motor based on an actual accelerator operation amount and an actual vehicle speed from the control map. This vehicle can alleviate discomfort caused when a driver accustomed to an engine vehicle operates an electric vehicle.
