Aluminum Jonny's EZ3 Leaner
It has two MTB rear suspension swingarms pivoting on either end of the original axle and controlled by a lateral “wobble bar” that attaches to the back of the frame through a rear suspension shock in the middle to provide a little suspension action too. The bar makes the swingarm toward the outside of a turn go “down” when the inside swingarm goes “up”, thus allowing the trike to lean into turns.
