A knee walker with four-wheel steering. The knee walker includes a frame, at least one front axle assembly, at least one rear axle assembly, a kneeling pad assembly, and a steering system. The steering system is configured to turn the rear axle assembly in the opposite direction from the front axle assembly. The opposing angles of the front and rear wheels enable the knee walker to perform tighter turns by eliminating rear wheel drag.

A wheeler kit includes a walking aid knee wheeler which supports a knee of a person having difficulty walking. The walking aid knee wheeler includes a chassis with a mounting interface and at least two wheel units which are pivotably mounted on the chassis in at least two axles. The wheeler kit further includes at least one module with a personal support which includes a knee support which is reversibly coupled in the mounting interface with the chassis, or at least one further module with a further personal support which includes a seat for at least one sitting position of the person. The at least one further module is reversibly coupled in the mounting interface with the chassis. The mounting interface is arranged further downward than a highest point of at least one of the at least two wheel units.

A foldable human-powered vehicle upon which users can ride is described. The vehicle includes a wheel assembly, a deck assembly, a seating assembly, a handle assembly, a deck support frame, and a brake assembly. The vehicle also includes a first and a second bicycle having a first handle disposed opposite a second handle. A first handle of the second bicycle is affixed to a second handle of a portion of the handle assembly to affix the second bicycle to the vehicle. A second handle of the first bicycle is affixed to a first handle of a portion of the handle assembly to affix the first bicycle to the vehicle. The vehicle also includes a rear component affixed to a portion of the deck assembly, where a head tube of a third bicycle is affixed to the rear component to affix the third bicycle to the vehicle.

A mobility scooter conversion kit and method that utilizes a standard mobility scooter as its base frame to make the scooter resemble any motor vehicle. The main frame of the scooter is only altered by adding an extension member with a bracket, replacing a first bolt on the seat frame with a long bolt, and reversing the orientation of a second bolt on the opposite side of the seat frame. The first body member that resembles the front of a motor vehicle has a recess that sits on the steering column of the scooter and is secured into place with a latching mechanism. The second body member that resembles the rear end of a motor vehicle is hooked on to the bracket of the extension member and secured into place using the long bolt and a bolt attachment connecting to the reversed bolt.

Provided are a mobility and a mobility system which enable a person who requires nursing care with a deteriorated bodily function or cognitive function to lead a life with greater independence. The drive and travel of the mobility by the travel drive unit are controlled by adjusting the current travel state of the mobility to an optimal travel state for ensuring safety while reflecting the user's intention based on the current operation instruction detected by the operation unit, the command signal generated by the voluntary control unit, the travel environment sensed by the environment sensing unit, and the respective types of environmental information acquired by the information acquisition unit.

A braking system for a rollator with a frame includes an adjustable handle to be installed on a right subframe or a left subframe of the frame of the rollator, a bracket fixedly connected to the handle, a lever rotatably connected to the bracket, a lock movably connected to the bracket and configured to fix the lever in a locked position when the lock is moved relative to the bracket once the lever is rotated toward the frame, and a wire operably connected between the lever and a brake on the frame of the rollator, such that the wire applies the brake when the lever is rotated toward the bracket and when the lever is fixed in the locked position.
