A wheeled, manually propelled vehicle with vertical support structure has an ergonomic handle attached to the support structure, the handle having a central section extending substantially horizontally in use and inclined sections which incline downwardly from the opposite ends of the central section and respectively terminate in curved end sections which curve toward the support structure and are integral for attachment plates for attachment to the support structure. The inclined sections facilitate grasping of the handle with an ergonomic arm position when a user is pushing the vehicle and facilitate maneuvering the vehicle around corners.
