The present invention discloses a self-balancing scooter. The scooter body includes: an upper shell, pedals, a middle shell and a lower shell. The upper shell includes a first upper shell and a second upper shell disposed symmetrically. The first upper shell and the second upper shell are provided with pedal holes respectively. Two pedals are disposed in the pedal holes of the first upper shell and the second upper shell respectively. The middle shell includes a first middle shell and a second middle shell disposed symmetrically and rotatable mutually. The lower shell includes a first lower shell and a second lower shell disposed symmetrically. The middle shell is located between the upper shell and the lower shell. The lower shell is provided with a depression. A plurality of horizontal and spaced strip-shaped ribs are disposed on the lower shell on an outer surface of the depression.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

A pair of foot lift attachments for attachment to single-wheel motorized electric skateboards, and combinations thereof. The foot lift attachments include a right foot lift attachment and a left foot lift attachment, each having a first concave curved outer facing side wall configured to be engaged on a curved support surface of either of a fender covering the single wheel, or a curved support surface of a mounting bracket secured at each side of the opening for the single wheel, and each having a convex curved top end wall with a concave curved underside configured to laterally receive and overlap the medial side and a top portion of the skateboard rider's foot and footwear worn on the foot to enable the rider to lift the skateboard off the ground with their feet and perform freestyle skateboarding maneuvers and aerial moves and jumps.

Methods and systems are provided for concave footpads for a personal transport device. In one example, the concave footpads may be coupled to the personal transport device, arranged between an operator's feet and an upper surface of the personal transport device, the upper surface including a pressure transducer.

An auto-balancing transportation device having a wheel structure and foot platforms that pivot between an in-use and a stowed position. The pivot axis for each platform is provided within the wheel structure so that the force exerted by a rider when stepping on a foot platform is applied to the wheel structure at a point within the wheel structure, as opposed to external to it, which is unstable and may cause the device to tip over.

A nose-dive prevention device for a one-wheeled motorized transportation device is disclosed, which has wheels that strike the ground in the event of a nose-dive situation, instead of the bumper, which could otherwise become abruptly hung and thus throw the rider. The nose-dive prevention device has a base for attachment to the front of the one-wheeled motorized transportation device, and one or more wheels connected to and extending from the base. The wheels are positioned to interpose between the front end of the one-wheeled motorized transportation device and the ground and contact the ground when the front end exceeds a nose-dive angle. However, under normal riding conditions, the wheels are spaced above the ground at a height sufficient to allow normal angular variability of the riding platform needed for control of the one-wheeled motorized device.
