Giant's entry into the fat bike market was long overdue, but it seems they did their homework when creating the excellent Yukon 1. This bicycle is our top choice for those riders looking for a fat bike solely for riding on snow. This fully rigid model features a sleek-looking aluminum frame paired with a composite fork. The moderate geometry that feels just right is also quite intuitive. It's stable at speed yet plenty maneuverable and reasonably capable on steeper rougher terrain with a skilled rider. It also comes with a dropper post which boosts the fun factor and takes its performance on descents to the next level. The Yukon climbs as well as it descends, with a great body position and a quality component specification and massive tires with decent rolling speed and loads of climbing traction. 
We found little not to like about the Yukon 1, but there are still some factors worth mentioning. While we loved it as an on-snow fat bike, it isn't the best choice for regular trail riding. While it is a competent descender, it is still a rigid bike and can be a bit jarring. It's also moderately heavy, and the massive tires can feel a bit draggy outside of the typical fat bike conditions. That said, for proper fat bike riding, the Yukon 1 really impressed us with its well-rounded performance.

The Rocky Mountain Blizzard 20 is not only reasonably priced but also an impressively capable fat bike. Rocky Mountain broke the traditional mold by giving the Blizzard a somewhat more aggressive geometry, especially the slacker headtube angle of 67-degrees. Due to the fact that it is longer and slacker than the competition, this bike has a notably more confident feel when pointed down steeper or slightly rougher terrain. It's still a rigid bike, but it feels more composed than most other models with more conservative geometries. The seated pedaling position is comfortable, and this bike plods along flat terrain and moderately pitched climbs just fine. The build is budget-oriented but perfectly functional, and the massive 4.8-inch tires have heaps of traction to help dampen the ride.
The biggest gripe our testers have with the Blizzard 20 is the weight. At over 35 lbs, the Blizzard is among the heaviest models we tested. This weight makes it feel a bit sluggish all around but is especially apparent when climbing. Our other concern is that with such massive rims and tires, the Blizzard's dirt riding versatility is somewhat diminished by the weight and drag. Despite these issues, we feel this is a great fattie for snow, sand, or adventure riding, and an affordable one at that.
