My brother and I have ICE Adventure fs's. Love their ability to fold; we can pack two in my Pontiac Vibe when we go on a trip. Not a fan of hanging them off the rear bumper; too afraid of being rear-ended, and of there being too great a temptation to thieves. Am impressed with the front and rear suspension; it's not for severe off-roading, but it is a great help when the road, or more often trail is rough.
