A personal transport vehicle is provided, which includes a front wheel assembly having a front rim and a front tire seated on the front rim, and a rear wheel assembly having a rear rim and a rear tire seated on the rear rim. The vehicle also includes a motor disposed within the rear rim of the rear wheel assembly and coupled to a mount of the rear rim, where the motor is configured to rotate the rear tire to cause movement of the personal transport vehicle. The vehicle further includes a frame coupled to the front wheel assembly and to the motor disposed within the rear wheel assembly, and a steering arm coupled to the front wheel assembly within the front rim for controlling movement of the front tire for steering the personal transport vehicle.

A bicycle frame is discussed having a battery fully contained within a down tube of the bicycle frame. The battery may be inserted into or removed from the down tube via a through opening through a bottom bracket housing of the bicycle frame. Weakness in the bottom bracket housing due to the through opening may be compensated for, fully or partially, by utilizing a bottom bracket bearing assembly that has a structural component, or structural component assembly, that extends completely through the bottom bracket housing and removably couples to the bottom bracket housing.

Embodiments include an off-road vehicle with a straddle seat, a plurality of ground engaging members, a prime mover and a frame having a removable frame portion overlying the prime mover, wherein at least a portion of the engine extends above at least a portion of the removable frame portion, and wherein at least a portion of the straddle seat extends over the removable frame portion and the prime mover.

This Tandem bicycle design describes a reduced linear dimension, whereby the inherent polar integrity of the tandem structure is reduced.

Due to the close proximity of the cyclist, balance and coordination is more rapid and spontaneous.

The gear construct is comprised of a system of three cranking sprockets, closely arranged in a forward (one) and rearward pair. The forward and rear gears closest to the bicycle frame; coupled to a timing chain, functions as the timing mechanism. The rearward outer gear functions as the driving gear connected by a power chain to the rear wheel sprocket(s).

The handlebars required by the rear cyclist necessitates an innovative base connected to the bicycle frame located behind the front cyclist seat collar.

A locking mechanism on the handlebar coupler allows deployment of handlebars from retracted, to the riding position.

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 battery unit for a drive mechanism for a bicycle comprises at least one decoupling element. This allows for a decoupling of a housing for receiving a battery from the bicycle frame. The battery unit may in particular be mounted in an elastically dampened manner in the bicycle frame.
