Description

A perfect introduction to trail riding or adventurous commuting, the Merida Big Seven / Big Nine hardtail is built around Merida’s sophisticated TFS aluminium frame, delivering confidence-inspiring geometry, excellent durability, and smooth handling on varied terrain.

Designed with trail capability in mind, the updated frame features modern MTB geometry: a longer reach, shorter stem, steeper seat angle, and slacker head angle — giving riders the stability they need off-road while still being agile and comfortable enough for everyday use. The frame includes thoughtful touches like internal cable routing, inboard disc brake mounts, and dropper post compatibility for future upgrades.

Equipped with a 100mm SR Suntour suspension fork, Shimano mechanical disc brakes, and a 2x7-speed Shimano drivetrain, this build balances cost-efficiency with real trail performance. The Kenda tyres, paired with either 29” or 27.5” wheels, offer great grip and stability, while the Shimano hubs, cassette, and chainset ensure reliable long-term performance.

Merida’s Agilometer-inspired sizing approach ensures everyone gets the right fit — the Big Seven (650b) for shorter riders and agility-focused handling, and the Big Nine (29er) for taller riders or those prioritising rollover speed and efficiency. The new XXS size option opens the door to even more riders.

With over 50 years of hardtail development expertise, Merida has created a confident, capable aluminium hardtail that’s ready for anything from gravel paths to green trails — with real upgrade potential for the future.

Description

Designed to deliver unbeatable value for riders looking to hit the trails without breaking the bank, the Merida Big Seven is a 650b hardtail equipped with a sophisticated TFS aluminium frame, making it ready for adventure and everyday use. With clearance for up to 2.4" tyres, the frame is built to handle rugged trails and rocky paths with ease.

The 120mm Suntour suspension fork offers superior comfort and control, while the lockout feature ensures efficiency on smoother sections. The Shimano MT200 hydraulic disc brakes provide smooth, consistent braking power in all weather conditions, and the Shimano 1x8 drivetrain simplifies shifting while still offering a versatile range for both technical climbs and fast descents.

Merida's trail-ready geometry includes a longer reach, shorter stem, and a slacker head angle, resulting in greater off-road capability while maintaining everyday usability. This geometry, combined with the internal cable routing and tapered headtube, ensures a clean look and plenty of potential for future upgrades.

The 27.5” wheels paired with Kenda tyres and Shimano hubs provide excellent traction, while the frame’s compatibility with a dropper post means you can upgrade as your skills progress.

Merida’s Agilometer sizing concept ensures the right fit for riders of all sizes. The Big Seven is ideal for shorter riders who prefer more agile handling, while the Big Nine (29er) suits taller riders seeking a bit more speed and efficiency. For riders in the middle, choosing between the two models can depend on riding style: Big Nine for speed, Big Seven for agility.

With over 50 years of experience in building durable, high-performance hardtails, the Big Seven is a true testament to Merida's expertise and commitment to quality. Whether you’re new to mountain biking or looking for a dependable trail companion, the Big Seven delivers on both performance and value.
