We're currently rolling with a 2014 RTS but finally got to ride F3s set up for me (6'2") and my wife (5'2") at Bike, Blues and BBQ. Previously I had only been able to ride an F3 with the footing set up in the "3" position. The ride was preferable enough that we'll be looking to go to the F3 sometime in the future. Can the foot position be changed easily so that we can quickly accommodate whichever of us wishes to ride or is it a bit of an ordeal?
