Merida Big.Seven 650b Hardtail MTB | Agile, Reliable & Trail-Ready
Backed by over 50 years of manufacturing expertise, Merida's legendary line of aluminium hardtails is engineered to deliver bombproof reliability and modern off-road capability. Following progressive mountain bike design, this 650b (27.5") hardtail features a longer reach paired with a shorter stem to give you sharp, responsive handling. The trail-ready geometry incorporates a steeper seat angle for efficient climbing and a slacker head angle to give you absolute confidence on steep, loose descents, all without compromising everyday usability.
At its core is a sophisticated, updated TFS aluminium frame that perfectly balances trail ruggedness with everyday versatility. Packed with premium details, it offers full internal cable routing for a clean look, inboard disc brake mounts that keep the caliper protected while maximizing stopping power, and a tapered headtube ready for future upgrades. It is even dropper-post ready for when you decide to take on more technical terrain. Up front, a high-performance 120mm SR Suntour suspension fork with an integrated lockout smooths out heavy impacts, roots, and rock gardens with progressive efficiency.
Powering your trail sessions is a modern, simplified Shimano 1 x 8 drivetrain, offering a clean handlebar cockpit and dependable single-ring shifting with less maintenance. When it is time to slow things down, Shimano MT200 hydraulic disc brakes deliver effortless, one-finger stopping power in mud, rain, or dust. Rolling on nimble 27.5" wheels built with smooth-rolling Shimano hubs and wide 2.4" Kenda tyres, this machine is size-tuned to maximize agility, quick acceleration, and sharp handling on every singletrack session.
