The Merida Big Seven 20 Mountain Bike is an affordable hardtail with design and spec built for an all-round ride. The lightweight Big Seven Alloy frame is durable and easy to control for a simple and comfortable ride. It runs a 2x8 speed Shimano Drivetrain which is more than capable when it comes to those hard climbs as it rolls with smooth efficiency and clean gear changes. The Suntour XCT30 HLO Fork with 100mm travel and lockout is in the sweet spot for fun and adventure, enough to handle the rough stuff yet still gives you an agile ride.
It wouldn't be the Big Seven without 27.5" Merida CC Wheels and 2.2" Tyres for a dynamic ride that is better suited to smaller riders. Ride with confidence, hitting every descent or turn hard thanks to the reliable Shimano Hydraulic Disc Brakes which give you excellent braking control. When compared to the lower end Big Seven 15, you get a simplified 2x8 drivetrain instead of 3x8, as well as a better fork and minor spec improvements across the bike. The Merida Big Seven 20 is an entry-level bike with a relatively lively and agile feel for an enjoyable ride that is comfortable on or off-road.
- Internal Cable Routing: Cables are routed through the frame, entering and exiting through smooth sockets. The bike looks neat, whilst the cables are protected from moisture and dirt.
- Racelite 61 Aluminium: We use a minimum of 6061 aluminium. The pay back is that it’s possible to make lighter and more advanced frames. We use an additional heat treatment and double-butted wall thicknesses to produce light and stiff frames.
- TFS: Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with an internal metal core.
