A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length and a width, a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a motor for providing a drive energy to the first wheel, an axle rotated by the motor, a drive gear connected with the axle such that the drive gear rotates with a rotation of the axle, and a plurality of teeth disposed about the first wheel and mechanically engaged with the drive gear at a location closer to the perimeter of the first wheel than to the geometric center of the first wheel.

The invention relates to a drive system for a vehicle, having a drive or electromotor, a crankshaft and a transmission, in particular a hub transmission. It is provided according to the invention that the transmission (10) is arranged in the central region of the vehicle, in particular the region of the crankshaft (1) and in particular is integrated and the crankshaft rotational speed is transmitted.

A vehicle suspension includes a center block and a suspension arm pivotally coupled to the center block. A hydraulic actuator is coupled between the center block and suspension arm. A wheel is mounted to the suspension arm opposite the center block. The hydraulic actuator is configured to lean the wheel. A brake rotor is mounted to a rim of the wheel through springs. A brake stanchion extends from a center of the wheel. The brake stanchion includes a center-mounted brake caliper. An axle is pivotally coupled to the center block at a first end of the axle. A constant velocity (CV) joint is mounted to a hub of the wheel with a second end of the axle extending into the CV joint. A steering tie rod is attached to a housing of the CV joint. The center block is attached to a vehicle frame.

A force measurement sensor includes a peripheral portion, a central portion, and a first frame connecting an upper section of the peripheral portion to an upper portion of the central portion. The central portion includes a seat intended to receive the outer ring of a bearing in order to mount a shaft in rotation about an axis Z. The frame includes a core enclosed by two arms which are substantially parallel to one another, such that the upper section of the peripheral portion, the upper portion of the central portion, and the two arms form a parallelogram.

Systems and methods are provided for locking a cycle. A clutch system of the cycle includes a forward lock system configured to alternatively prevent or allow operation of the cycle in a forward direction. A shaft extends through the clutch system. An actuator is configured to move the forward lock system along the shaft between a lock position and a free position. A controller is configured to shift the actuator, via a signal from a processor, between the lock position and the free position. The cycle is configured to be locked against forward operation by the clutch system.

A straddled electric vehicle includes an electric motor including an output shaft oriented in a direction perpendicular or substantially perpendicular to a vehicle width direction, a drive bevel gear that rotates around a rotation axis oriented in a direction perpendicular or substantially perpendicular to the vehicle width direction, a driven bevel gear that rotates around a rotation axis oriented in the vehicle width direction, and a drive pulley that rotates around a rotation axis which is oriented in the vehicle width direction. The drive bevel gear and the driven bevel gear convert rotation generated by the electric motor around a rotation axis oriented in a direction perpendicular or substantially perpendicular to the vehicle width direction into rotation around a rotation axis oriented in the vehicle width direction, which is transmitted to the drive pulley.
