A snowboard has a removable tripod at the rear. A tiller mounts atop the tripod. The rider end of the tiller supports a motor. The distal end of the tiller supports a powered wheel. The power assembly doesn't compromise the shape and dynamics of a traditional snowboard as much of the prior art has. Another advantage is that it can be made integral with the snowboard and also easily removed. The ease of control with the handle and radical turning ability of over 180° make it unique in this field. The tripod mounting and balancing are also unique and useful. It is lighter in weight and simpler than previous embodiments in this are. The tiller can be locked with the wheel up for freestyle snowboarding.
