I also bought a Safari this year. Pretty happy with the bike so far. One feature that attracted me was the offering of a "29er" wheels on the Large and XL frames. Ended up the Medium was the "correct" size for me. The M bike is spec'd with 26" wheels. Overall I like the bike. I did notice the extra weight of the wheels when accelerating the bike and so just as happy I ended up with 26 vs 29er wheels. I do notice the lack of a second water bottle mount on the compact style frame on the bike.
