Summary
The Specialized Fuse is a highly capable cross-country bike that excels in climbing and handling, offering a unique blend of fatbike-like traction and trail bike-like agility. Its playful geometry and reliable components make it a fun and economical choice for riders looking to tackle a variety of trails without the maintenance of full suspension. While the 6Fattie tires provide excellent traction, they can feel sluggish compared to narrower options, and some components may not meet expectations for the price.
Climbs incredibly well
Fatbike-like traction and trail bike-like handling
Playful and easy to coax from one corner to the next
Well-constructed aluminium frame
Reliable, economical parts
6Fattie tires are a little sluggish compared with normal 2.3-inch-wide rubber
Rear tyre prone to sliding out on corners
Raidon fork is a spec disappointment for the price
The Fuse climbs incredibly well.
Ignore the spec, this is a capable plus-hardtail ideal for letting loose on fast flowing trails.
The Fuse is an exceptionally fun bike that delivers without a huge outlay of cash.

But plus-bikes like the Specialized Fuse Comp are more than just boisterous playthings — despite their portly appearance, the best of them are capable of going seriously damn fast.. .

Hardtails aren’t dead. Not by a long shot. Specialized’s new Fuse Expert Carbon 6Fattie proves that thanks to its fun geometry, excellent parts spec, and agreeable price point. - Mtbr.com

3″ tyres on mountain bikes. Yes, ‘semi fat’ is now officially a thing. Get used to it, we’ll be seeing ‘semi fat’ bikes popping up a lot as we roll toward 2016. The new standard will surely provoke heated discussions and much throwing of hands in the air. But for now we’ll cast all opinions …
Boat loads of fun.
All the excitement of riding a hardtail.
Traction!
Corners and climbs anything in its path.
Sluggish on buff trails.
Clunky Manitou fork.
Pricey for the spec.
