We tested 13 MTBs at Interbike in 2015. Only 6 are still made today.

Ten years ago, there was this bicycle tradeshow called Interbike. Retailers gathered each September to learn about products for the next season and to place their orders. Brands showed off their latest and greatest. And journalists — including members of the Singletracks team — sampled new bikes and products from brands across the industry.

It’s been almost exactly 10 years since Interbike 2015, and that year, Singletracks test rode 13 different mountain bikes at the Bootleg Canyon Outdoor Demo area. Feeling nostalgic, we wondered: “How many of those bikes and/or bike brands still exist?” Read on to find out which ones made it — and which ones did not.

✅ Surly Wednesday fat bike

Looking back, 2015 was peak fat bike. We published an article from Interbike that year showcasing 22 brand new fat bike models, and pretty much every brand had one, or was rushing to slap their label on a new bike. But as you’ll see below, many of those fat bikes are no longer being produced.

Ten years later, the Surly Wednesday is a survivor and is one of three fat bikes the brand still offers. The Wednesday actually made its debut that year, and was priced at $1,500 for a complete bike. Today, the price isn’t a whole lot higher at $1,849.

✅ Pivot Mach 4 Carbon

Back in 2015, Pivot was still offering most, if not all, of their bike frames in both aluminum and carbon, hence the “Carbon” tacked onto the name of this bike. Technically, the Mach 4 is now the Mach 4 SL, but the bike still targets the same XC race-oriented rider. Even the 115mm of rear travel is the same, though clearly the geometry and kinematics (and sloped top tube!) have been refined significantly over the years. The $5,899 MSRP at the time of testing is within $600 of the price of an entry-level Pivot Mach 4 SL today.

❌ Intense Carbine 29C

The Intense Carbine 29C was a highly regarded mountain bike for its time, with our tester noting how quiet and responsive the bike felt on the rocky, dusty trails outside Las Vegas. Though the Carbine 29C is no longer available, the Intense Primer boasts similar travel specs, though with an all-new linkage system. In 2015, this Intense “Pro” build was priced at $6,700; today, a Primer Pro costs less, at $6,399.

❌ Cannondale Fat CAAD

Cannondale appears to have bowed out of the fat bike market in 2021, and a search on the website today yields no results. The brand’s Fat CAAD was revolutionary for its use of the Cannondale Lefty fork because, at the time, there was only one other fork — the RockShox Bluto — that fit fat tires.

✅ Fuji Auric One.1

Fuji tends to be associated with budget-friendly mountain bikes in the US today, but that wasn’t always the case. In 2015, we tested this $5,400 aluminum build featuring 27.5″ wheels, a Pike fork, a one-by drivetrain, and tubeless tires. To be honest, I’m surprised to see the Auric is still around, and still rocking 27.5″ wheels front and rear. An Auric 27.5 build with Maxxis tires and a Marzocchi Bomber fork sells for $2,999 on the Fuji website today.

✅ Rocky Mountain Altitude

The Rocky Mountain Altitude is still very much alive in 2025! Of course, in 2015, none of us would have imagined an electric version of the Altitude, or even mixed wheels. As best I can tell, the 2015 Altitude was running matched 27.5″ wheels, and there wasn’t a flip chip for adjusting the geo. In his review, Aaron noted the Altitude frame included a spot to mount a front derailleur for those who preferred a two-by drivetrain. How quaint.

❌ Alchemy Oros

Earlier this year, Colorado-based Alchemy announced the brand was up for sale. Though it’s uncertain how that will shake out, what is for certain is that the Oros hardtail is no longer with us. As Jim noted in his review, carbon Oros frames were hand-crafted in Colorado, with complete build prices approaching $10,000. For a hardtail.

Coincidentally, Alchemy announced its full-suspension bike, the Arktos, at Interbike 2015. That bike was available as of earlier this year, though a recent check shows all remaining Arktos bikes are sold out.

❌ Ellsworth Buddha

Ellsworth has always been known for their eye-catching frames, with swoopy lines and strong graphics and finishes. The Buddha fat bike was no exception, and this carbon-fiber wünder-bike was designed to showcase Ellsworth’s parent company’s carbon fiber technology.

It doesn’t appear any bikes are for sale on the Ellsworth website currently, but a message on the homepage promises “Big Changes are Coming” with a note that says “We are taking a break during the summer to go and enjoy our Ellsworth Bikes. We will be back and operational in December 2025.” The Truth and Rogue frames currently shown online look very unique, so I’m excited to see what the brand has in store for the future.

✅ Giant Reign Advanced

Yes, the Giant Reign Advanced is still very much available, though this paint job is not. I’ve got just three words: Bring. It. Back!

In 2015, the Reign sported matched 27.5″ wheels, and today’s bike is offered with mixed wheels with the option of running 29er wheels front and rear. The bike’s enduro intentions remain the same, with 160mm of Maestro rear suspension paired with a 160mm fork. In 2015, a Giant Reign Advanced 1 was priced at $5,200 compared to $6,800 today.

❌ Marin Attack Trail 9

Marin’s current trail bike, the Alpine Trail, is very different from the brand’s 2015 trail bike, the Attack Trail 9. With the ‘9’ in the name, I assumed it was a 29er, but in fact the bike was running 27.5″ wheels front and rear. It came with a fork and shock from BOS, a suspension brand that’s still operating today, though I haven’t seen them specced on a bike in years.

Prices for Marin trail bikes have gone up a smidge since 2015, though the brand continues to provide a pretty good value at the lower end of the price spectrum.

❌ Reeb Donkadonk

The Reeb Donkadonk truly was redonk. Not only was it a fat bike, it came with a Gates Carbon belt drive and an internally geared Rohloff hub. This build featured a RockShox Bluto fork, which made it pretty dang capable overall. Sadly, the market for fat bikes slowly melted away.

Reeb is still going strong, producing full-suspension steel bikes right here in the USA. If anything, the brand’s gravel bike, Sam’s Pants, carries the Reeb Donkadonk mantle as a go-anywhere bike.

❌ Scott Big Ed

Ed’s dead, baby. Ed’s dead.

The Scott Big Ed is another fat bike that didn’t live to see its tenth birthday, discontinued sometime around 2018. Despite the aluminum frame, massive tires, and suspension fork, our test bike weighed just 32lb, less than many of today’s high-end trail bikes. Of course, it’s a hardtail, and there wasn’t a dropper post, but it did have a remote fork lockout!

✅ Transition Patrol

In 2015, the Transition Patrol featured 27.5″ wheels front and rear, though today the bike ships as a mixed-wheel build. The suspension configuration and overall aesthetics haven’t changed drastically over the past decade, though clearly the geometry has been modernized. Of all the bikes in this list, the Patrol seems to have aged the best.

Your turn: What mountain bike were you riding in 2015? Is it still around today?
