I rode the trike today, albeit without the motor turning the back wheel. It was a fun ride. I had to figure out how to steer the trike (which I did after the video below). I tightened the back wheel too much and then had a hard time loosening. Please note that I had to take the trike to a bike shop to get pump the wheels with air. I felt like I was in a Strong Man competition (that thing is heavy)!
