I've tried several kinds of reclining sleds, but this one is my hands-down favorite. For one thing, it can take a spill or two and not get damaged. It's varnished, not painted, so you can see the wood grain. The birch rails are a nice touch, too. It's super stable, and turns very nicely, which is good, because this thing is FAST! Loads of fun - when we go sledding, this is the sled that everbody wants to use. 5 stars

I've had my flyer now for a couple of winters and absolutely love it. It's beautiful on display in the living room corner, and we take it up to the Cascade passes as much as we can when we stay at the lodge. I've given Mountain Boy Ultimate Flyers as gifts to friends with young kids, and there's nothing more exciting than a wintery sledding get-together. These things are fantastically fast, very well-built, and totally controllable with the steering. Beats anything I had as a kid!! 5 stars

We used our new Mountain Boy Ultimate 52" on our Christmas trip (2007) to Estes Park, CO. On the third trip down a hard-packed hill, our sled stopped dead with my husband on it. Looking underneath we discovered both black plastic pieces had chunks broken off and missing and cracks running from the broken sections. This occurred without striking anything with a measurable impact. It was irreparably damaged. Boy were we disappointed! Later, upon further inspection, we also discovered the middle plank of the long (lower) section cracked almost up to the pivot point. That seemed even worse than the broken undercarriage since the wood on the sled is so beautifully finished.
We contacted Mountain Boy Sleds in Silverton, CO upon our return home (to Houston) and sent them pictures of the damaged sled. Brice Hoskin,of Mountain Boy, handled the matter quickly and better than we could have hoped. Thank you, Brice.
Pros: It is the most beautiful sled I've ever seen. (We're going to hang it on the wall as a display.)
Travels at a good speed. Faster and longer distance than most other sleds.
Turns okay.
Great customer service. They care about your sledding experience.
Cons: It's heavy. Parents will be toting that thing up the hill for the kids after most every run.
The Flexible Flyer had greater speed (but we only got to use the MB on three runs, so this might not be totally fair.)
Our sled didn't turn as smoothly as we expected, but that could be that it needed time to loosen up.

I still don't have a lot of confidence in the black, plastic undercarriage and really prefer the runners like those on a Flexi-Flyer, but we bought what we bought. MB offers sleds with the metal runners if you prefer that style. If you want a beautifully crafted sled that performs on par with the Flexible Flyer, then buy this sled. 4 stars

I purchased this sled as a birthday present for my grown son. He has two young boys and there is enough snow in Illinois to make use of the sled. It turned out to be an excellent gift as they use it to spend family time together. The sled is a beautiful wood grain. It is a little more narrow than I expected and the runners on the bottom are a wide plastic although my son feels that makes it much safer. The front steers very easily. My son and his boys are winter outdoors people and love the sled. 5 stars
