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 rear wheel suspension device includes: a swing arm swingably supported with respect to a vehicle body frame, the swing arm being configured to rotatably support a rear wheel; a rear cushion configured to be extended and contracted in accordance with swing of the swing arm; a cushion lever coupled to a lower end portion of the rear cushion; a cushion rod coupling the cushion lever and the swing arm; an accumulator storing a working fluid that extends and contracts the cushion rod; and an accumulator bracket supporting the accumulator. A vehicle height is adjusted by displacement of the swing arm in accordance with extension and contraction of the cushion rod. A muffler pipe extends rearward from an engine through a side of the accumulator. The accumulator bracket is configured to separate the accumulator and the muffler pipe.

A motorcycle includes an electric motor having an output shaft defining a motor axis, a rear wheel drivably coupled to the electric motor to propel the motorcycle, a swingarm rotatably supporting the rear wheel, and a frame. The frame includes a main frame member supporting the electric motor and the swingarm. A case of the electric motor is a stressed member of the frame between the main frame member and the swingarm. The swingarm is coupled to the case of the electric motor to define a swingarm pivot axis that is co-axial with the motor axis.

A control device includes a reference unit, a correction unit, and a target setting unit. The correction unit sets a reference correction current serving as a reference in determining the correction current to 0 in an extremely low velocity range of a change velocity of a stroke amount, sets the reference correction current to a predetermined steady-state value in a medium and high velocity range of the change velocity, and sets the reference correction current to a value equal to or larger than 0 and equal to or smaller than the steady-state value in a low velocity range of the change velocity.
