A bicycle frame includes a substantially rigid front frame portion and a substantially rigid rear frame portion. A link is connected to the rear frame portion by a first pivot and to the front frame portion by a second pivot. A frame segment is rigidly connected at a first end to one of the rear frame portion and the front frame portion and pivotably connected at a second end to other of the rear frame portion or the front frame portion by a third pivot. The frame segment is flexible proximate the second end.

An adjustable assembly for a bicycle includes a first support having an interior surface and a second support slidably positioned within at least a portion of the first support. One of the first support and the second support is adapted to attach to a first bicycle portion, and the other of the first support and the second support is adapted to attach to a second bicycle portion. Further, the second support comprises an expansion portion configured to be moved between an expanded position and a retracted position. The expansion portion is configured to engage the interior surface of the first support when the expansion portion is in an expanded position. In addition, the first support is configured to be selectively moved relative to the second support when the expansion portion is permitted to assume a retracted position.

A kick scooter includes a frame having a head tube for supporting handlebars and a front fork, an elongated frame member extending along a length of the frame, the frame member having a first end attached to the head tube and a second end configured for attachment to a rear wheel, the frame member being angularly disposed relative to the head tube. The frame includes support member coupled to the frame member for adjustable movement along a length of the frame member, a knee pad is attached to the support member for supporting a rider's knee and shin. The support member is movable relative to the frame member for adjusting a position of the knee pad relative to the head tube and a riding surface. The kick scooter further includes front and rear wheels, and a handlebar attached to the frame.

A personal mobility vehicle, such as a scooter, includes a plurality of wheels supporting a deck or other vehicle body portion. The vehicle has a movable portion that is movable relative to another portion of the vehicle.
