This is a tricycle with a pretty good rig. When you move it, the wheels rotate and the petals remain parallel with the ground. That way its ready for a rider too! To use it, simply move the empty marked move, in any direction or stick it to a path or whatever! And to steer (who rides in a streight line right!) just rotate the empty marked Steer. This is my 1st rig like this and I am not very praticed at it, and thanks to Olson I somehow managed to get it to work! Thanks again Olson for showing me how to set up the front wheel.
