Merida ONE-SIXTY FR 600

About the Merida ONE-SIXTY FR 600

Merida's ONE-SIXTY FR 600 sits somewhere between enduro workhorse and downhill bruiser, and it wears that split personality with pride. The FR badge signals freeride intent - think repeated bike-park laps, rock-garden plunges, and the kind of riding where you're more interested in how fast you can scrub speed into a berm than how quickly you topped out the climb. Built around a stout aluminium frame with 180mm of DVO travel up front and a coil-sprung 171mm rear, this is a bike that prioritises composure when gravity takes over. The mullet wheel setup - 29-inch front, 27.5-inch rear - adds a flick of playfulness to what could otherwise be a one-dimensional descender, and the result is a machine that begs you to pop off lips and manual through flat sections rather than simply point and shoot.

Merida hasn't chased grams here. Instead, the focus lands squarely on durability and descending performance, with TRP's four-piston Trail EVO brakes and Continental's Kryptotal rubber underscoring the brief. The frame carries ASTM Category 5 certification - the highest rating for gravity use - and a five-year warranty that suggests Merida expects you to test those limits. Shimano Deore 12-speed keeps things simple and reliable, while the DVO Onyx 38 fork and Jade X coil shock deliver the kind of small-bump sensitivity and mid-stroke support that flatter rough trails and tired arms. You're not buying a featherweight here, but you are getting a bike that'll handle abuse, inspire confidence on steep chutes, and still pedal back to the top without feeling like a boat anchor.

The Agilometer sizing concept lets you choose frame size based on reach and handling preference rather than inseam alone, so shorter riders can opt for longer wheelbases and stability, while taller riders can size down for a more flickable feel. A flip-chip in the rear linkage allows you to swap between the stock mullet configuration and a full 29er setup if you want to prioritise rollover and traction over that rear-wheel lift. It's a thoughtful touch that broadens the bike's appeal beyond pure park rats to anyone who wants enduro capability with a freeride edge.

Merida ONE-SIXTY FR 600 geometry

Merida describes the geometry as progressive, and the numbers back that up even if the brand doesn't shout them from the rooftops. The head angle sits slack enough to inspire confidence when the trail pitches down, while the seat angle keeps your weight forward enough to avoid that dreaded back-seat shuffle on climbs. Reach options span a wide range thanks to the Agilometer sizing - five frame sizes from XShort to XLong - so you can dial in the cockpit length that suits your riding style. Longer reach frames plant you over the front wheel for stability at speed and in rough terrain; shorter options tighten the wheelbase and quicken the steering for riders who prize agility and manual-ability over outright composure.

The mullet wheel configuration shortens the rear centre compared to a full 29er, which lifts the rear wheel more easily and makes the bike feel livelier through tight switchbacks and jump transitions. You'll notice that playful character the moment you try to loft the front - there's less inertia to fight. The flip side is a touch less traction and rollover at the back, though the 27.5-inch wheel's lower axle path also helps the suspension track the ground through square-edge hits. If you prefer the planted feel of dual 29-inch wheels, the flip-chip lets you convert the geometry to suit, raising the bottom bracket slightly and slackening the angles a fraction to accommodate the taller rear wheel.

Standover height stays low across the size range, a deliberate choice that pairs with Merida's long-travel dropper posts to give riders more freedom in frame selection. You're not locked into a size by leg length, which means you can prioritise handling feel over fit charts. The result is a bike that can feel stable and confidence-inspiring in a longer size, or nimble and poppy in a shorter one, depending on what you're chasing on trail.

Component choices & upgrades

The stock build punches well above its price point, particularly in the suspension and braking departments. DVO's Onyx 38 fork is a serious piece of kit - air-sprung with low-speed compression and rebound adjustment - that you'd normally find on pricier builds, and the Jade X coil shock delivers the kind of mid-stroke support and small-bump sensitivity that makes rough descents feel smoother than they have any right to. TRP's four-piston Trail EVO brakes offer powerful, consistent stopping with 220mm front and 203mm rear rotors, and they've earned a reputation for reliability under hard use. Continental's Kryptotal tyres - Enduro Soft casing up front, DH Soft at the rear - prioritise grip and durability over rolling speed, which suits the bike's gravity focus perfectly.

Shimano Deore 12-speed is the workhorse drivetrain choice here, offering a 10-51T cassette range that covers steep climbs without fuss. It's not the lightest or flashiest option, but it shifts cleanly, takes abuse, and parts are easy to source when you inevitably wear through a chain or cassette. The Merida-branded alloy cockpit - 780mm bar, 40mm stem - sets a sensible baseline for aggressive riding, though riders with narrower shoulders or a preference for even shorter stems might swap the bar or stem to fine-tune fit.

If your skills or terrain demand more, the most obvious upgrade path is tyres. Swapping the DH-casing rear for a lighter Enduro casing or a faster-rolling tread will wake up the bike's pedalling manners without sacrificing much grip, especially if you're spending more time on trail than in the park. A lighter wheelset would shave rotating weight and improve acceleration, though the stock Merida Expert TR II rims with their 28mm internal width are plenty capable and won't leave you wanting unless you're chasing marginal gains. The coil shock is a boon for descending but can feel a touch dead on long climbs; if you're planning big days with extended pedalling sections, an air shock swap would liven things up, though you'd lose some of that coil's magic on the way down. Beyond that, the build is well-sorted - grips, saddle, and dropper post are all functional, and there's little reason to throw money at them unless personal preference dictates otherwise.

Where the Merida ONE-SIXTY FR 600 excels

This bike is outstanding at one thing above all: descending fast, rough terrain with your arms and brain still fresh at the bottom. Bike parks, steep natural trails, rock gardens, root-strewn chutes - anywhere gravity does the work and you're managing speed rather than generating it - the ONE-SIXTY FR 600 thrives. The suspension soaks up repeated hits without packing down, the geometry keeps you centred and confident, and the brakes let you scrub speed late into corners without drama. The mullet setup adds a dose of fun to proceedings, making it easier to manual, pump transitions, and generally ride with more flair than a pure DH sled would allow.

It's also very good at aggressive trail riding where the descents matter more than the climbs. If your local loops feature long, technical descents punctuated by shorter, punchy climbs, the FR 600 will reward you on the way down and won't punish you too badly on the way up. The coil shock and DH-casing rear tyre do cost you some pedalling efficiency, but the Deore drivetrain's wide range and the bike's composed climbing posture mean you're never stuck walking. Riders who value a forgiving, confidence-inspiring ride over outright speed will appreciate how the bike flatters rough trails and tired legs.

Where it's not ideal: long, sustained climbs, especially on smoother surfaces where the extra weight and rolling resistance become more noticeable. If your rides involve big elevation gains on fire roads or you're chasing Strava times uphill, lighter enduro bikes with air shocks and faster-rolling tyres will leave the FR 600 behind. It's also overkill for mellow trail centres or cross-country loops - the suspension travel and burly build are wasted on terrain that doesn't demand them. This is a bike for riders who accept that climbing is the price of admission for the descents they really care about, not for those who want a balanced all-rounder.

Merida ONE-SIXTY FR 600 FAQs

What is the travel of the Merida ONE-SIXTY FR 600?
The fork offers 180mm of travel via the DVO Onyx 38, while the rear shock delivers 171mm through Merida's FAST kinematic suspension. That's enough cushion for bike-park laps and rowdy natural descents without feeling like you're riding a full downhill rig on the climbs.

Is the Merida ONE-SIXTY FR 600 good for climbing?
It climbs adequately rather than enthusiastically. The coil shock and DH-casing rear tyre add weight and drag, and the geometry prioritises descending stability over climbing efficiency. You'll get to the top without drama, but lighter enduro bikes with air shocks will feel livelier and faster on sustained ascents.

What type of riding is the Merida ONE-SIXTY FR 600 best suited for?
Bike parks, aggressive trail riding, and gravity-focused descents where you want confidence, control, and a bike that won't complain when you push hard. The mullet setup adds playfulness, so it's also a solid choice for riders who like to manual, pump, and session features rather than simply point downhill.

What are the key features of the Merida ONE-SIXTY FR 600 frame?
Lite aluminium construction with large TIG-welded joints, ASTM Category 5 certification for gravity use, internal cable routing via the Acros headset, ISCG chain guide mount, and a flip-chip that lets you switch between mullet and full 29er setups. The frame also carries a five-year warranty, which speaks to Merida's confidence in its durability.

How does Merida's Agilometer sizing work?
It decouples frame size from leg length by offering low standover heights and long-travel dropper posts across the range. You choose size based on desired reach and handling - longer frames for stability and composure, shorter frames for agility and quicker steering - rather than simply matching your inseam to a size chart.

What are the advantages of a mullet wheel setup on a mountain bike?
The 29-inch front wheel rolls over obstacles more easily and provides better traction and stability, while the 27.5-inch rear wheel reduces rear-centre length, making the bike easier to manual, flick through tight corners, and pump through transitions. You get the planted feel of a big front wheel with the playful, poppy character of a smaller rear.

What is the warranty on the Merida ONE-SIXTY FR 600 frame?
Merida backs the aluminium frame with a five-year warranty, one of the longest in the category. It's a clear signal that the brand expects the frame to handle the abuse that comes with bike-park laps and aggressive trail riding.

Can the Merida ONE-SIXTY FR 600 be converted to a full 29er?
Yes. The flip-chip in the rear linkage allows you to swap from the stock mullet configuration to a full 29er setup. Doing so raises the bottom bracket slightly and adjusts the geometry to accommodate the taller rear wheel, prioritising rollover and traction over the mullet's playful lift and flick.
