Nothing new, just a reminder that all these trailers become instant handcarts the minute they are disconnected from the bike. The seat-post hitch is a snap no bending and groping around in the crud at your rear axle,-just pull a pin and voila a nice padded handle at exactly the right height for moving your trailer around. AND YES! THAT INCLUDES OUR SINGLE WHEELERS. Just another good reason to choose Tony's Trailers.
