The Merida One Forty is a versatile and fun trail bike that excels in climbing and offers a balanced, efficient ride. Its suspension is smooth and supportive, making it a great all-rounder for various trail conditions. The bike's geometry and handling are praised for their stability and intuitiveness, though some note it could be more stable at high speeds.
Super friendly and forgiving vibe
One of the best climbers out there
Smooth, efficient and fast across the ground
Versatile all-round trail bike
Great balance between stability and nimbleness
Hefty for a carbon frame
Not as stable at high speeds
Headset cable routing makes servicing a pain
Steep seat angle puts more weight through your wrists
Despite looking rad on paper, the Merida actually feels super balanced on the trails.
The One-Forty is one of the best climbing mountain bikes I’ve ever ridden.
The new Merida One-Forty is a fantastic example of a modern, do-it-all trail bike.

If first impressions are anything to go by, Merida’s latest logically-named One-Forty trail bike, looks like the kind of do-it-all rig you’d expect from a mainstream brand – with a well-finished, smooth-lined carbon frame and fancy big-name kit. Dig a little deeper though, and Merida’s latest creation kicks any conservative ideas to touch faster than you can say ‘Rishi Sunak’. With real attitude and some of the most radical trail bike geometry around, the new One-Forty is seriously cutting edge. Buyer’s guide to the best full-suspension trail bikes Buyer’s guide to the best mountain bikes Need to know The new One-Forty shares the same frame with the One-Sixty, which means it’s a little ‘overbuilt’ as a trail bike and subsequently heavier than some. Merida’s ‘Agilometer’ sizing sees super long frames extending to a massive 535mm reach in size X-Long Thankfully the 80º seat tube angle is not as steep as claimed Fully Mullet compatible and gains 10mm more travel (153mm) with the smaller rear wheel. Low standover heights are paired with the brand’s own adjustable dropper post that extends up to 230mm. While most brands have scaled back the leaps in frame length that have revolutionised sizing over the last decade, Merida has gone full throttle. The mid (medium) bike here has a 480mm reach, a near vertical 80-degree effective seat angle, which we’ll get to in just a minute. It’s so long in fact, that the 535mm reach on the X-Long frame makes it the same length as an XL Nicolai Geometron – one of the pioneers of the longer frame philosophy. Merida’s new ‘Agilometer’ sizing system goes on frame length rather than seat tube height, so all five sizes come with very low seat tubes with stacks of standover clearance. This leaves tons of room for the rider to be dynamic on the bike and lowers the centre of gravity. But let’s get back to the 80º effective seat tube angle. It sounds crazy steep, right? That’s because Merida measures it with a saddle height that would correspond to the top of the head tube, not very useful for seated pedalling. Raise the saddle to something normal, say 740mm, and the effective seat tube angle decreases to 78º or thereabouts. Which is spot on. Choosing your optimum saddle height isn’t an issue either, thanks to Merida’s clever adjustable dropper post with a maximum 230mm of drop. Bigger frames also get a different suspension tune with more damping and support for heavier riders that typically opt for longer sizes. Now, part of the explanation for the progressive geometry on the One-Forty is that it shares its frame with the new One-Sixty enduro bike. By fitting a shorter stroke (57.5mm) shock (rather than 65mm) travel is limited to 143mm. It also gets a shorter travel 150mm fork, which steepens the angles, drops the BB and increases the reach over the One-Sixty. To compensate for the steeper seat tube angle, Merida fits a 10mm lay-back head on the dropper post. Yes, …Continue reading »
Consummate all-rounder that’s a fantastic climber. Smooth, efficient and fast across the ground and very stable at speed. Category 5 frame is rated for bike park or even DH use.
Shock tune on Fox DPS shock lacks a smidge of mid-stroke support. Reynolds Black Label carbon wheels are a bit sharp and stiff. Adjustable dropper post adjuster ‘box’ can occasionally catch on your thighs. At 14kg, it’s not as light as you might expect for an £8K trail bike.

On paper Merida’s brand-new One-Forty platform looks rather mental but, in reality, it’s a very different animal than its geo chart suggests. It offers a unique-but-welcoming and practical ride that balances predictability with all-out fun. Its build kit has been wisely picked considering its asking price, too; making it one of the best trail mountain bikes you can buy.

Awsome bike for all day riding in alpine regions. Steep trails up and down are its habitat. Can do also trail parks, as long you stay on small jumps (
Awsome and fast climber
efficient rear suspension and kinematics,
no bobbing even at open schock,
front stays glued to the ground even on very steep terrain,
masters everything' possible uphill,
fun and forgiving ride downhill,
bike has veey long wheelbase so it's very stable at any speed,
I just can't stop riding it,
the geo somehow motivates you, to run faster, harder, more,
1x11 drivetrain deore is super, reliable and cheap,
Bike and frame worth upgrading and keeping for longer time,
lifetime warranty for first owner,
looks that could kill: aesthetic,, nice,
strong brakes (deore 4 piston)
Fork durability: mine died on me after three days (3500 altitude meters and 90km). It seezed up. marzzocchi couldn't service it in four weeks. When they finally did, it was assembked wrong (140mm airshaft, instead of 150). Returned it. Waiting for another 3. weeks So the fork Marzzocchi Bomber Z2 is super sharp, plush, but durability is worse than some suntour. To bad, this means $$ for a new fork (no Marzzocchi any more),
32T chainring is a bit heavy for steep climbs. But you can get cheap steel 30 or 28 T.
