A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.

An adjustable rear wheel hood system has a movable hood, so to be longitudinally adjusted to accommodate shrinking wheels (due to wear), or other requirements. A longitudinal slot is aligned between the rear wheel hood and the deck, and after adjusting the hood-to-rear wheel separation to a desired amount, the hood is secured to the deck. Either the deck or hood is configured with the slot, while the other piece has holes and/or alignment features that align the pieces together, provide a way to secure the pieces together, and also prevent lateral movement of the hood. A similarly configured adjustable non-braking rear hood is described.

In some embodiments, an electric scooter comprises a deck configured to support a rider, front and rear wheels, a handlebar assembly that includes a handlebar, a left handle, and a right handle, a steering column that includes a steering tube and the handlebar assembly, and an electric motor configured to provide mechanical power to at least one of the front and the rear wheels. One or more of the steering column, steering tube, handlebar assembly, handlebar, left handle, right handle, and deck can be configured to be detachable and comprise one or more rechargeable battery packs. In addition, one or more of the steering column, steering tube, handlebar assembly, handlebar, left handle, right handle, and deck can be configured to receive one or more removable rechargeable batteries.

A foot brake structure for a mobility device includes: a footboard having an upper surface extending in a plane direction and having a rear wheel at a rear thereof; and a friction plate positioned above the rear wheel, having a portion extending forward of the rear wheel and rotatably assembled to a rear end of the footboard by a rotating shaft, and having a lower surface brought into contact with or spaced apart from a surface of the rear wheel depending on whether or not the friction plate is rotated around the rotating shaft, wherein when the friction plate is rotated around the rotating shaft by an external force, the lower surface of the friction plate is brought into contact with the surface of the rear wheel, thereby applying a braking force to the rear wheel.

One variation of a system includes: a cam block mounted to a deck of a scooter and defining cam lobes arranged about a pivot feature and cam heels between the set of cam lobes; a pivot block pivotably coupled to the pivot feature and defining followers riding over the cam lobes; a pair of wheel uprights locating a pair of wheel assemblies; a first lateral link extending between and coupled to the pair of wheel uprights and pivotably coupled to the pivot block; a second lateral link extending between and coupled to the pair of wheel uprights, vertically offset from the first lateral link, and coupled to the pivot block between pair of wheel uprights; and a spring element driving the followers of the pivot block into cam heels to bias the second lateral link toward a neutral position.

A braking apparatus for stopping a children's kick scooter is described. The braking apparatus comprises a hand-held remote control to transmit a command signal when a radio-frequency (RF) signal transmitter is activated. The braking apparatus also comprises a remote control signal receiver located on the children's kick scooter to receive the command signal and convert it to an electric current. The braking apparatus additionally comprises a linear actuator to receive the electric current. The linear actuator comprises a linear actuator electric motor and a linear actuator shaft. The linear actuator electric motor is activated by the electric current and moves the linear actuator shaft from a first position to a second position. The braking apparatus further comprises a brake system to press a metal plate against a rear wheel of the children's kick scooter, thereby stopping the children's kick scooter when the linear actuator shaft is in the second position.
