An adjustable handlebar assembly for fitting a bicycle to a user having disparate arm reaches includes a handlebar, which comprises left and right sections. A lower end of the left section and a bottom end of the right section are rotatably engaged and define a midpoint of the handlebar. The handlebar is mountable by its midpoint to a handlebar stem of a bicycle. Left and right grips of the handlebar are independently positionable relative to a rotatable plane, which is perpendicular to a front wheel of the bicycle and which extends longitudinally through the handlebar stem. The left and right sections are fixedly engageable so that the left and right grips are fixed relative to the rotatable plane. The left and right sections being selectively positionable allows them to be engaged by left and right hands, respectively, of a user having a reach disparity between their arms.

A bicycle handlebar accessory (or bicycle pod) 20 is disclosed which may be secured in a bicycle handlebar tube 24 and arranged into a deployed configuration 500. A host bicycle 10 with a pair of bicycle pods 20 secured in opposite ends of the handlebar tube 24 may be inverted for inspection or repairs while the bicycle pods 20 stabilize the inverted bicycle and keep the handlebar 24 (and any accessories mounted thereon) spaced from the ground 26 and away from potentially hazardous materials and conditions, including water, ice, frozen or super-heated pavement, sand, gravel, or other surface hazards such as road salt or deicing chemicals. The disclosed bicycle pod 20 may include a main body 28, a distal shaft 30, a proximal shaft 32, and a coil spring 34.

A powered handlebar adjustment assembly adapted for use with a vehicle having first and second forks aligned in a parallel relation along a first longitudinal axis, first and second triple tree supports aligned in a second axis transverse to the first axis, and a set of handlebars mounted parallel to the first and second triple trees and transverse to the first and second forks. The assembly includes a first and second telescopic supports, each having a first section thereof mounted between and in parallel with the first axis of the first and second forks and between and transverse to the axis of the first and second triple tree supports. A second section is mounted between the first triple tree and the handlebars at a proximal end of the second section and concentric with the first section at a distal end of the second section for translation relative thereto between the first and second forks and parallel thereto. First and second actuators are mounted between the first and second forks and between the first and second triple tree supports. Each actuator is operationally coupled to the second section of a telescopic support via the first section thereof. Actuation of the actuators via a switch mounted on the handlebars is effective to cause the second sections of the telescopic supports to translate relative to the first sections thereof and thereby move the handlebars from a first position to a second position.
