Merida ONE-SIXTY FR 400

About the Merida ONE-SIXTY FR 400

The Merida ONE-SIXTY FR 400 exists to answer a simple question: what if you could afford a bike that actually survives bike park season? Built around a triple-butted aluminium frame that wears its Category 5 rating like a badge of honour, this is Merida's statement that freeride progression needn't cost mortgage money. The 2026 model brings DVO suspension front and rear - Onyx 38 fork up top, Jade X coil out back - paired with a geometry that's slack enough to inspire confidence yet playful enough to reward commitment. It's a bike that prioritises suspension performance and durability over gram-shaving, and that focus shows the moment you point it downhill.

Merida's FAST kinematic suspension platform underpins the whole package, working with that coil shock to deliver sensitivity at the top of the stroke, support through the middle, and proper bottom-out resistance when you overshoot the landing. The P-FLEX flexstay design ditches the traditional seat stay pivot, shedding weight and maintenance while adding a touch of natural compliance that takes the sting out of square-edged hits. You're looking at 180mm of fork travel and 171mm at the rear, wrapped around a mullet wheel setup - 29-inch front, 27.5-inch rear - that balances stability with the ability to flick the bike around tight sections. If you prefer full 29er manners, a flip chip lets you convert without fuss.

This isn't a bike that pretends to be a lightweight trail dancer. At around 17.6 kilograms, it's honest about its intentions: bike park laps, rowdy enduro stages, and trails where robustness trumps race-day weight. The aluminium frame might not win stiffness-to-weight contests, but it'll shrug off impacts that would leave carbon frames weeping in the workshop. For riders who want maximum fun and progression without the premium price tag, the ONE-SIXTY FR 400 delivers exactly what it promises.

Merida ONE-SIXTY FR 400 geometry

Merida's Agilometer sizing concept lets you choose reach independently of your height, which means you can dial in the handling character you want rather than simply fitting onto a frame. The head angle sits at 63.5 degrees across all sizes - slack enough to inspire confidence on steep, technical descents without feeling like you're wrestling a shopping trolley through tighter sections. Paired with a 78-degree seat angle, you're positioned forward enough to weight the front wheel on climbs and keep traction when the gradient kicks up, yet the overall stance remains balanced when you're charging downhill.

Reach grows progressively from 409mm on the XShort through to 519mm on the XLong, and Merida's deliberately kept chainstay length varied by size - from 400mm on the smallest frame to 470mm on the largest - so the bike's agility and suspension feel scale with the rider. Shorter stays on smaller sizes keep the bike flickable; longer stays on bigger frames add stability without sacrificing playfulness. Stack height climbs from 620mm to 643mm as you move up the range, ensuring taller riders aren't folded into a cramped cockpit.

The 44mm fork offset and moderate bottom bracket drop work together to deliver a front end that's planted yet responsive. You'll feel the bike settle into rough ground rather than skitter across it, and when you need to change direction mid-descent, it responds without the vague, ploughing sensation that overly slack bikes can suffer. The mullet wheel setup shortens the rear centre slightly compared to a full 29er, which sharpens turn-in and makes manual-ing over obstacles easier, while the big front wheel rolls over chatter and holds momentum through rock gardens. If you want the calmer, faster-rolling feel of dual 29-inch wheels, the flip chip conversion is there, though you'll trade a little of that playful rear-end snap.

Component choices & upgrades

The stock build on the ONE-SIXTY FR 400 is already well-sorted for its intended use. DVO's Onyx 38 fork and Jade X coil shock are proper enduro-grade suspension components, offering the kind of damping performance and tunability that used to live only on pricier builds. The coil shock comes with progressive spring rates matched to frame size - 300 pounds for XS, scaling up to 500 pounds for XL - so you're not left hunting for the right spring out of the box. Four-piston brakes (Tektro Gemini or SRAM DB4, depending on final spec) with 203mm rotors front and rear deliver stopping power that won't fade halfway down a long descent, and Continental Kryptotal tyres - Enduro compound up front, Downhill compound at the rear - give you grip where it counts.

The Shimano CUES drivetrain is durable and shifts cleanly under load, though it's not the lightest or most refined option. If you're chasing marginal gains or prefer crisper, faster shifts, an upgrade to Shimano Deore XT or SRAM GX would sharpen the experience, but for most riders the stock setup will handle everything from bike park abuse to long enduro stages without complaint. The 32-tooth chainring and 11-48 cassette (or 10-50, depending on final 2026 spec) offer enough range for steep climbs without leaving you spinning out on fire roads.

Where you might consider upgrades is if your riding consistently pushes beyond the bike's stock intentions. A lighter wheelset would wake up acceleration and climbing, though the Merida COMP TR II rims are tough enough to survive repeated impacts. If you're racing enduro rather than sessioning jump lines, swapping to a lighter saddle and grips will shave a few hundred grams without compromising durability. The dropper post travel varies by size - 150mm on XS/S, 170mm on M, 200mm on L/XL - which is generous, though taller riders on the XL might appreciate a 230mm post if their inseam allows. Tyres are always personal, but the Kryptotal pairing is a smart choice; if you want more rolling speed on hardpack, a faster rear tyre won't hurt, though you'll sacrifice some braking traction.

Where the Merida ONE-SIXTY FR 400 excels

This bike is outstanding at bike park laps and aggressive trail riding where suspension performance, durability, and confidence-inspiring geometry matter more than outright weight. Point it at a jump line, a rock garden, or a steep, root-strewn chute, and it rewards commitment with planted, predictable handling and suspension that soaks up mistakes. The coil shock delivers consistent damping lap after lap, and the robust aluminium frame shrugs off the kind of abuse that would leave lighter bikes creaking and cracked. If your weekends involve shuttle runs, lift-accessed descents, or trails where you're more concerned with survival than Strava times, the ONE-SIXTY FR 400 is in its element.

It also handles enduro racing and long, technical descents with composure. The geometry keeps you balanced through steep sections, and the mixed-wheel setup gives you the stability of a big front wheel with the manoeuvrability of a smaller rear. When the trail tightens or you need to hop over an obstacle, the bike responds without feeling sluggish. Climbing is competent for a long-travel freeride machine - you'll notice the weight on sustained fire road slogs, but the steep seat angle and suspension platform mean you're not fighting the bike on technical ascents. It's not a trail bike that moonlights as an enduro rig; it's the other way around, and that focus is deliberate.

Where it's not ideal is if you're chasing lightweight performance, racing cross-country, or spending most of your time on mellow, flowing trails. The weight and travel are overkill for less demanding terrain, and you'll feel every kilogram when you're trying to accelerate out of corners or sprint up short climbs. If your riding is more trail-centre loops than bike park carnage, a shorter-travel enduro bike or an aggressive trail bike will feel livelier and more efficient. The ONE-SIXTY FR 400 is built for riders who want maximum capability on descents and don't mind carrying a bit of extra weight to get it.

Merida ONE-SIXTY FR 400 FAQs

What is the Merida ONE-SIXTY FR 400 best suited for?
Bike park laps, aggressive trail riding, freeride, and enduro racing where suspension performance and durability are priorities. It's built for riders who want a robust, capable bike that handles rough terrain and repeated impacts without breaking the bank.

Is the Merida ONE-SIXTY FR 400 a good bike for bike parks?
Absolutely. The 180mm fork, 171mm coil-sprung rear, and Category 5-rated frame are designed to survive the demands of bike park riding. The suspension soaks up landings and rough sections, and the geometry inspires confidence on jumps, drops, and technical features.

What are the key differences between the Merida ONE-SIXTY FR 400 and other enduro bikes?
The FR 400 prioritises suspension performance and durability over lightweight components, with a coil shock and robust aluminium frame. It's heavier than some competitors but offers excellent value, and the mullet wheel setup (convertible to full 29er) adds versatility that many rivals don't offer at this price point.

How does the mixed wheel setup on the ONE-SIXTY FR 400 affect its ride?
The 29-inch front wheel rolls over obstacles and holds momentum, while the 27.5-inch rear keeps the bike playful and easier to manual or flick through tight sections. It's a balance of stability and agility that suits aggressive riding, though you can convert to full 29er if you prefer calmer, faster-rolling handling.

What is the warranty on the Merida ONE-SIXTY FR frame?
Merida typically offers a limited lifetime warranty on frames, but specific terms vary by region and retailer. Check with your local Merida dealer for exact coverage details, as warranties often depend on proof of purchase and proper maintenance.

Can the Merida ONE-SIXTY FR 400 be converted to a full 29er?
Yes. The frame includes a flip chip that lets you swap from the stock mullet setup (29-inch front, 27.5-inch rear) to full 29-inch wheels. You'll need a 29-inch rear wheel and tyre, but the conversion is straightforward and doesn't require additional parts.

What are the recommended suspension settings for the Merida ONE-SIXTY FR 400?
Start with 25 - 30% sag on the coil shock and around 20 - 25% on the fork, then adjust based on your weight, riding style, and terrain. The coil shock's progressive spring rates are matched to frame size, so most riders will find the stock spring works well. Fine-tune rebound and compression damping to suit your preferences.

Is the Merida ONE-SIXTY FR 400 suitable for long enduro races?
It's capable on enduro stages, especially technical descents, but the weight will be noticeable on long liaison climbs. If your races involve significant pedalling between stages, a lighter enduro bike might be more efficient. For shuttle-assisted or lift-accessed enduro events, the FR 400 is a strong choice.
