Jogging stroller
A jogging stroller that operates in a walk mode and a run mode. The stroller has a frame having a handle, a front wheel and two rear wheels. The stroller also has a wheel locking mechanism to lock and unlock the front wheel from rotating about a pivot axle of the wheel. The wheel locking mechanism is operated by a twist assembly of the handle. The stroller also has a handle locking mechanism to lock the twist assembly and the wheel locking mechanism in one of the walk mode and the run mode. Additionally, a user can temporarily move the twist assembly to an actuated position when the handle locking mechanism is in the run mode to allow the front wheel to rotate about the pivot axis until the twist assembly is returned to the normal position.
