A two wheel vehicle is propelled by hand-grasped poles. A front wheel on a forward member and a rear wheel on a rearward member align along a longitudinal axis. The forward member pivots about a substantially vertical steering axis. A saddle and footholds support the rider and together with an accessory contact allow the rider to balance and steer the device. The rider's hands do not contact the vehicle but are used to propel the vehicle with the poles.
