My wife had a great time on the TW yesterday riding with a couple of friends on their ATV. I've still been experimenting with the best off road air pressure. Yesterday I tried 10 in the front and 6 in the back. That worked very well as less than 10 in the front made the steering difficult. The TW works very well 2-up but of course caution and slow speed when riding two in the backcountry is always advised.
