Systems and methods are described for providing a high-rise ahead-type handlebar stem for a bicycle. Embodiments of the high-rise ahead stem include a main stem tube and a handlebar stem tube. The main stem tube includes a proximal region non-overlapping with a distal region. The proximal region includes a rotational securement structure. The handlebar stem tube extends from the distal region and terminates in a handlebar interface structure. The high-rise ahead stem provides various features, including relatively simple adjustment of handlebar height over a relatively large range of heights, while maintaining a high level of strength.

A stem assembly and an electric vehicle are provided. The stem assembly includes: a stem telescoping mechanism including a first hollow tube, a second hollow tube, and a locking mechanism, the locking mechanism having a locked state and an movable state; a handle folding mechanism arranged to the stem telescoping mechanism, the handle folding mechanism including a handle assembly and a first limiting member, the first limiting member being movably arranged, and having a first limiting position and a first evading position; and a driving mechanism connected to both the locking mechanism and the first limiting member, and configured to be operated to control the stem telescoping mechanism and the handle folding mechanism to synchronously move.

Apparatus is for, or is included with, a vehicle having a vehicular handlebar, and also having first and second pipe portions. The first elongated portion is configured to receive and support a vehicular handlebar, and to be slidably received, at least in part, in the second elongated portion. An engagement device is configured to selectively engage the first and second pipe portions with each other. The engagement device, in use, prevents the first and second pipe portions from rotating relative to each other. The engagement device is also configured to selectively disengage the first and second pipe portions from each other. The engagement device, in use, permits the first and second pipe portions to rotate relative to each other. A clamp assembly is configured to selectively clamp the first elongated portion and the second elongated portion with each other.

Aspects of the disclosure relate to saddle type vehicles having at least one seat and at least two wheels, at least one electric motor, and a rechargeable electric energy storage system, such as a battery and battery management system. A vehicle seat may be mounted on an adjustable inner seat post, where the adjustable movement may be vertical, substantially vertical, or at least partially vertical. Vehicle handlebars may be mounted on an inner shaft which allows movement parallel to the steering axis and is indexed to an outer steering stem that allows the handlebars, a chassis fork and front wheel to be steered together. In some examples, the inner seat post and handlebar inner shaft are electronically raised and lowered, for example by one or more electrical stepper motors, such that position of handlebars and seat may be selected by rider.
