Been riding every day with 13.1 and 13.2 on my trails. It's awesome to be able to step out the front door and do some pretty good rides. Once Hickory Hills lake is frozen will attempt the trek to #3's on sleds. Yesterday I rode the Safari with 13.2 on the Ovation and 13.1 on the Scoot and we did every trail in my system and had a great time (total ride 15.2 mles). Riding the Safari that far was like a flash back to my youth!! Both kids are really loving it which the best - 13
