Versatile
Solid all-around performance
Excellent build for the price
The YT Jeffsy AL Base is the clear winner of our Editor's Choice Award for a mountain bike in this price range. The Jeffsy truly punches above its weight class and could easily compete with bikes that cost thousands of dollars more. This is largely due to the fact that YT sells direct to the consumer, giving them a serious upper hand in the price to component spec/performance ratio. Testers found virtually nothing they didn't like about this versatile and well-rounded mid-travel trail bike. It has relatively middle of the road geometry numbers that help to make it comfortable and competent climber. That same geometry also works in its favor on the descents, with moderate angles that perform well in all situations and quality components that you can have confidence in. The Jeffsy is balanced and composed, stable yet surprisingly playful, and a straight-up joy to ride.
It's hard to find fault with the Jeffsy, but it isn't exactly lightweight at 31 lbs 10 oz. Interestingly, the weight of this bike never seemed to be an issue, maybe we were having too much fun to notice. Beyond that, it's all gold stars for the Jeffsy, a solid all-around mid-travel trail bike, and an amazing one at this price.

Climbing - 35% 8
Excellent price to build ratio
Well-rounded performance
Versatile
Came with wrong length dropper post
Moderately heavy
When we tested the Siskiu T8 it was the most expensive model in the test. It was a solid value at that price, and since then the price has come down by $300 making it an outstanding value. Polygon is another consumer-direct brand and this bike has a price to build kit ratio that other models just can't touch. Much like the YT Jeffsy, the Siskiu impressed our testers with its especially well-rounded performance and components that take its performance to another level. Its geometry is modern yet moderate, helping to make it comfortable and capable on both the climbs and the descents. This bike rips on the downhills, with an outrageous blend of stability and agility along with composure and balance that performs well at a huge range of speeds and trail conditions. It's no slouch on the climbs either, it rolls fast and has a comfortable seated pedaling position, direct and precise steering, and handles technical and tight uphill sections well.
The Siskiu is great but not perfect. Our test bike came spec'd with the wrong length dropper post, 125mm instead of 150mm. This didn't affect the way the bike performs or how much we enjoyed it, but it's not impressive from a quality control standpoint. With a weight of 31 lbs 8 oz, it's a little bit portly but it manages to feel lighter underneath you than that number suggests. We also experienced a very slight knocking sensation in the lower rear shock mount that we had a difficult time getting rid of, though it generally wasn't an issue out on the trail.

Burly aggressive feel
Modern trail bike geometry
Long dropper post
Proper beefy tire specification
Heavy
Mediocre fork
sluggish climber
The Process 134 29 is a ripping mid-travel trail bike that is capable of charging way harder on descents than our testers expected for a bike in this price range. Kona's bikes typically perform well on the downhills, and even the entry-level version of this bike handles speed and aggressive terrain with the confidence and composure we've come to expect from the brand. The 134mm of rear-wheel travel is paired with a 140mm fork which is ideal for a huge number of riders and locations and will rarely leave you wanting for more. The geometry is modern and progressive, spot on by today's standards and the primary reason this bike rips so hard. Add to that some thoughtful component specs like a dialed cockpit with proper 170mm dropper post as well as beefy durable tires that enhance this bike's aggressive performance.
The Process 134 29 isn't without fault. At over 34 lbs, it's the heaviest bike in this review and that weight is very noticeable, especially when compared to the lighter bikes in this review. While some aspects of its build are dialed, the important job of handling the front end travel is left to a low-end RockShox Recon fork. The fork works fine, but it isn't ideal for handling the hard-charging nature of this bike. That said, the rider who prioritizes downhill performance and isn't that concerned about weight should give the Process 134 a look.

Energetic playful feel
Lighter weight

Marzocchi fork
Fork needed immediate service
Limited by modest travel numbers
The Giant Trance 29 3 is a sporty short travel trail bike and a solid all-around performer. This bike's liveliness and playful attitude make it one of the most fun bikes to ride in this review, and its downhill capabilities far exceed its short-travel pay grade. It feels like it has more than 115mm of rear-wheel travel thanks to Giant's excellent Maestro suspension platform that pairs very well with the 130mm Marzocchi Z2 fork. The Z2 is a departure from the typical budget fork specs, and after having it serviced it outperformed those found on other bikes in this price range. The Trance 29 has a moderate modern geometry that gives it excellent versatility, and it feels highly maneuverable and comfortable at a range of speeds and terrain. It's also one of the most energetic and efficient climbing bikes of the bunch.
There was little not to like about the Trance 29 3. Testers did find, however, that it could be overwhelmed in aggressive terrain due mostly to the fact that it has less travel. You can ride just about anything on this bike, it just requires a little finesse and good line choices when the trails get rough and rowdy. Otherwise, testers were quite impressed with the playful, versatile, and affordable performance of this short travel ride.

Analysis and Test Results
There's no question that mountain bikes are expensive, and these days many complete full suspension bikes can cost about as much, or more, than your first car. Fortunately for consumers, many brands are making affordable models that are actually trail-worthy and you won't need to sell a kidney or take out a second mortgage to purchase. Yes, you can spend upwards of $10K on a fancy new mountain bike, but we're finding that some of these budget-friendly models are just as much fun and won't break the bank.
Over the course of several months, our Tahoe based mountain bike testers rode the trails throughout the Tahoe Basin and surrounding areas. All the bikes in our test selection were put through their paces on a wide range of trail types, with test laps that aimed to hit the full spectrum of mountain bike riding. Every aspect of each bike's performance was scrutinized and scored on three rating metrics that are discussed in greater detail below.
We ride these bikes as if they are our own, pushing them to determine their strengths, weaknesses, and ride characteristics.
All of the bikes reviewed here are different, with varying geometry numbers, component specifications, and strengths and weaknesses that define the way they perform out on the trail. When our testing concluded and the dust settled, the YT Jeffsy AL Base was the clear winner of our Editor's Choice Award, offering performance and a very high component to price ratio. Other bikes excelled for different reasons, like our Best Buy Award winner the Polygon Siskiu T8 for its confidence-inspiring trail manners, solid component specification, and well-rounded versatile performance. The Giant Trance 29 3 earned our Top Pick Short-Travel bike award with a lively and playful character, solid climbing performance, and downhill chops that exceeded our short-travel expectations. Kona's new Process 134 29 also earned itself an award by setting itself apart from the competition with its hard-charging downhill capabilities.

Value
If you're reading this review, chances are you're interested in finding the best budget-friendly mountain bike under $2,500 for your riding style. The bikes in this review all fall within a few hundred dollars of each other and the differences in price really aren't very extreme. On the other hand, the differences in performance and component specifications are quite apparent, although pretty much every bike we tested qualifies as being a pretty good value. While the Polygon Siskiu T8 may not be the least expensive model we tested, it does have a very impressive component specification for the price, making it the best value in the test.
Fun Factor
We ride mountain bikes because it's fun, and we assume that you do too. We rated each bike in this review on our tester's impression of how much fun they had while riding each model. Some bikes are more fun to ride than others, with a playful demeanor and versatility that makes them perform well at all times. When the rider and bike become one unit and you can forget about the bike to focus on the trail, you're probably having lots of fun. Other bikes are less fun to ride, inspiring less confidence, have a less well-rounded performance, or are built with components that hold you back from having a great time. We find it's easy to differentiate between bikes that are simply a blast to ride, and those that keep you on edge the entire time.
Our Best Mountain Bike Under $2500 Editor's Choice Award winner, the YT Jeffsy AL Base, was the clear winner in this rating metric, with a geometry and component specification that is especially keen to party on the trail. The Jeffsy is impressively well-rounded, a capable climber that has the ability to keep it mellow or get as aggressive as you want on the descents, and a build that inspires the confidence to do so.
The YT Jeffsy AL Base knocked our socks off with a great well-rounded performance, impressive build for the price, and a higher fun factor than the competition.
The Best Buy Award-winning Polygon Siskiu T8 is another bike that is shockingly capable with a well-rounded performance that simply performs well everywhere. Bikes like this are fun to ride since they have such balanced trail manners that can handle a huge range of speeds, trail types, and conditions. The Giant Trance 29 3 also proved to be a blast to ride and it earned our Top Pick Short Travel Award. The Trance brings a high degree of liveliness and a playful demeanor to the table in a short-travel package that really impressed us with its versatility and well-rounded performance.
The Process 134 rips on the descents. This bike is almost too much fun when it's pointed downhill.
The new Kona Process 134 29 is a mid-travel downhill slayer that comes to life when pointed down the hill and speeds increase. This bike is far more capable and confidence-inspiring on the descents than most bikes in this price range, and an absolute blast when riding fast or tackling more aggressive terrain.
If you like to ride fast you might enjoy the Habit 6.
Downhill Performance
Arguably the most important element of a mountain bike's performance for most riders is how it performs on the downhill. There are a number of factors that dictate the way a bike descends, most notably geometry and component specification. When everything comes together a good downhill performer is versatile, responsive, and inspires confidence in the rider.
Three bikes battled for supremacy in the downhill performance rating metric. The Editor's Choice Award-winning YT Jeffsy AL Base, the Best Buy winning Polygon Siskiu T8, and Kona Process 134 29 are pretty evenly matched on the descents. Both YT and Polygon sell direct to the consumer and both have the most impressive build kits of all the models in this test. It's not all about the components, but there is absolutely no question that their beefier suspension, wheels, and tires do a lot to enhance their capabilities on the descents. In addition to their builds, both bikes share similar modern, but reserved, geometries that help to give them their well-rounded trail manners. While some bikes take their geometry to extremes, the YT and the Polygon strike a great balance that enhances their versatility. Both bikes perform well at a range of speeds and manage to stay somewhat playful and surprisingly stable at the same time.
The Polygon Siskiu is a very capable bike on the descents thanks to its geometry and impressive component specification.
Earning out Top Pick Award for its hard-charging downhill performance, the Kona Process 134 29 impressed our testers with its impressively capable and confidence-inspiring performance on the descents. This bike is ready for anything and really comes to life when you let it run or get into steeper, rougher terrain. It may lack the higher-end suspension components of the YT or the Polygon, but it feels plenty capable regardless.
The short-travel Giant Trance 29 3 may not be the hardest-charging bike on the descents, but it brings a playful attitude and more capability than its short-travel numbers might suggest. If you're more interested in popping side hits than plowing through the gnar at speed, then the Trance 29 might be right up your alley. The Trek Fuel EX 5 is a very comfortable and competent bike on the descents. This mid-travel ride has supple suspension and a smooth ground-hugging feel. It may not have a lot of pop or pizzazz, but it certainly was capable and fun to ride on a huge range of terrain and speeds.
Most mountain bikers spend the majority of their time riding bikes uphill. Fortunately, the Trance 29 3 is as good going up as it is fun to ride back down.
Uphill Performance
You gotta get up to get down, and as mountain bikers, we typically spend the majority of our time riding while going uphill. A bike's weight, geometry, suspension design, and components all play a role in how well a bike performs while climbing, and some are better suited to it than others.
Considering their downhill performance scores, both the YT Jeffsy and the Polygon Siskiu perform very well on the climbs. Both bikes feel fast-rolling and have similar seated pedaling positions and geometries that perform well in a range of uphill riding situations. They've got predictable and consistent traction that combines with precise and direct steering to make earning those descents more pleasurable than most.
You've gotta get up to get down, and the Jeffsy is great at both.
One of the fastest and most comfortable climbers, the Giant Trance 29 3 is a short travel ripper that performs almost as well on the ups as the downs. The Trance 29 feels quick and energetic when pointed up the hill, with comfortable geometry and reasonable weight compared to many of the other models in this test. The Giant Trance 3 2019, wasn't a standout on the climbs, but its geometry and Maestro suspension made for a comfortable and reasonably efficient uphill performance.
Neither the Kona Process 134 29 or the Trek Fuel EX 5 are the fastest climbers, but both bikes get the job done.
Both the Kona Process 134 29 and the Trek Fuel EX 5 were plenty competent but relatively unimpressive on the climbs. Both bikes work just fine, but their heavier weights definitely contribute to lethargic and unexciting climbing performance. The Cannondale Habit 6 is more of a descent oriented bike, and it had somewhat awkward uphill handling due to its long wheelbase and reach plus a slack head tube angle that results in a vague and sluggish feel uphill.
Build
Every bike we tested comes with a different component specification, or build, that is determined by the manufacturer. The components of a mountain bike are one of the primary factors that influence not only performance but also the retail price. In the sub $2500 price range a few hundred dollars goes a long way in the quality of components attached to a frame, and generally speaking, you're better off spending a little bit more for a better build. It took a while, but in recent years higher-end technology has finally begun to trickle down to less expensive mountain bikes and sometimes the differences between the high and low-end versions of components is negligible. One thing is certain, most of the budget-conscious bikes in our test selection are trail-worthy and shred-ready. It's important to note that all of the moving parts on mountain bikes eventually require maintenance. Brakes, drivetrains, suspension, dropper posts, if they move they will eventually wear out, and the more you ride the faster it will happen.
The component specification or build of each bike varies significantly and is a huge factor that affects each model's overall performance. The Polygon Siskiu T8 has a great build.
One of the most impressive builds in our test selection is that of the YT Jeffsy AL Base. This bike is ready to rip with beefier suspension, powerful brakes, a 1x12 speed drivetrain, meaty Maxxis tires, a dropper seat post, and a comfortable cockpit set up. The component spec to price ratio and performance that this bike delivers is incredible. This bike is seriously ready to go straight out of the box with a build you'd normally find on much more expensive bikes. The Polygon Siskiu T8 is similarly well-equipped to the Jeffsy. It also boasts a stout suspension package, powerful brakes, quality wheels and tires, a dropper post, and a Shimano XT/SLX drivetrain.
The Giant Trance 29 3, has a good component specification for the price. It can't match the build on the YT Jeffsy, but it gets the job done for less. It has a comfortable cockpit, plush suspension, a 12-speed drivetrain, and an especially shred-ready set of wheels and tires. The 27.5-inch wheeled Trance 3 also came quite well equipped for the price with a stout fork and burly wheels and tires.
The builds of bikes in this price range have improved dramatically in the past couple of years. Most now come with quality tires and dropper seatposts helping to make them more shred-able than ever before.
The Kona Process 134 and the Salsa Horsethief came with relatively similar builds. Both bikes have the same front suspension in the form of a RockShox Recon fork. They also both sport similar wheels and tires that are tubeless-ready and beefy enough to stand up to hard trail riding. Their cockpits are generally dialed too, with short stems, wide handlebars, and dropper posts to enhance their handling. The Cannondale Habit 6 has an okay build and it performs relatively well on the trail. The lack of a dropper post is the most egregious aspect of the build, especially for a bike that is so good on the descents.
You don't have to spend a fortune to get a bike that performs well on the trail. There are several worthy options in this review that'll put a smile on your face.
