A handheld device may include a support shaft, a power source, a working assembly operably coupled to the support shaft and powered by the power source to facilitate performance of a working function of the handheld device, and a handle assembly operably coupled to the support shaft. The handle assembly may include a handlebar coupling a first handle disposed at one end of the handlebar and a second handle disposed at an opposing end of the handlebar, a handlebar coupler rotatably coupling the support shaft and the handle assembly, and a locking lever. The handlebar coupler may be configured to selectively enable rotation of the handlebar about a first axis and a second axis based on a position of the locking lever.
