A steering apparatus with forward extended fork legs includes left and right fork legs that extend from a wheel axle all the way up to a handlebar. Top fork portions support a handlebar in a more forward location. A mid-fork portion of each fork leg is positioned in front of the steering column to provide more clearance room for the rider's knees. The top ends of the fork legs are positioned a forward distance in front of the vertical axis defined by the steering column. Each fork leg may be tilted forward with respect to the steering column and may also include a forward bend to direct portions of each fork leg towards the front.
