A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.

Convertible caster board

A vehicle may include a pedal assembly, a motor assembly, and a drive unit that may be used to allow selective usage of one or both of the pedal assembly and the motor assembly to convey power to a driven wheel of the vehicle. The drive unit can include a gearbox that may enclose components which form at least part of a first power path between the pedal assembly and the driven wheel and a second power path between the motor assembly and the driven wheel. The first and second power paths can converge at a component within the gearbox. One-way bearings at points in the first and second power paths prior to the convergence of the power paths can inhibit or prevent the pedal assembly from being affected by operation of the motor assembly, and vice versa.

Motorized mid-drive unit

Various personal mobility vehicles, such as scooters, are disclosed. The scooter can include at least one battery and motor for powering at least one driven wheel. The vehicle can include a gear assembly to convert a torque produced by the motor to a different torque to a driven shaft to power the at least one driven wheel. The battery can be removable.

Electric scooter

Various hub motor arrangements, systems, and methods are disclosed. The hub motor arrangement may include a transmission assembly to provide increased torque. The transmission assembly may include a motor gear, a planetary gear, an idler gear, and a ring gear. The idler gear may be positioned farther away from an axis of rotation of the hub motor arrangement compared to the planetary gear. The motor gear may drive the planetary gear, the planetary gear may drive the idler gear, and idler gear may drive the ring gear. The rotation of the ring gear may rotate a housing of the hub motor arrangement to propel a vehicle incorporating the hub motor arrangement.

Hub motor arrangements, systems, and methods

Various electric balance vehicles are described. In some embodiments, the vehicle has first and second housings with platforms to support a user's feet. The first and second housings can be rotatable relative to each other. The vehicle can have first and second wheel assemblies. A support member can extend within tapered portions of the first and second housings. In some embodiments, one of the first and second housings can rotate relative to the support member and the other of the housings can be rotationally fixed relative to the support member. The vehicle can balance and provide locomotion to the user. The vehicle can be light, compact, and/or have a low center of gravity.

Electric balance vehicles

An electric powered personal mobility vehicle that includes at least one front wheel and an electric motor that provides rotational force to a wheel of the vehicle. The electric motor is supported by the vehicle and is powered by a rechargeable battery that is also supported by the vehicle. The vehicle can also include swivel caster wheels each configured to rotate about a wheel axis.

Powered personal mobility vehicle with rotating wheels

A personal mobility vehicle or scooter includes a least one swivel caster wheel supported at the rear of the scooter. The scooter has a body that includes a deck and a handlebar assembly. The scooter includes at least one front wheel with the deck extending between the at least one front wheel and the at least one swivel wheel. The scooter can also include an angled rear portion supporting a rear swivel caster wheel such that the pivot axis of the swivel wheel is inclined with respect to the top surface of the deck. Embodiments of the scooter also include a swivel braking assembly configured to apply a braking force to the at least one swivel wheel.

Scooter with rear swivel wheel

A locking mechanism can be used for securing a scooter or other vehicle. The locking mechanism can secure a wheel of the scooter in a left or right steering position. The locking mechanism can be manually actuated by the user, such as by a foot or hand of the user. Once the wheel is secured in place, the scooter may be difficult to ride without unlocking. The locking mechanism can be unlocked through a wireless connection with a remote control (e.g. a phone).

Scooter steering lock

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.
