  • Entry-level 27.5" wheeled hardtail built around our double butted aluminium frame with a more comfort inspired geometry. The 27.5" wheels help to cover ground efficiently and in perfect control and impress with easy acceleration and nimble riding characteristics. The Suntour fork helps to improve the comfort even further, and the broad gear range of the triple chainring Shimano drivetrain let you conquer even the steepest hills with ease.

    The alternative to our BIG.NINE 29er hardtails for riders who prefer the smaller 27.5" wheels. The latest aluminium frame generation of our BIG.SEVEN TFS and SPEED mountain bikes featuring slim tube shapes create a new look and a more relaxed geometry. A shorter top tube and a higher head tube offering a more upright riding position and enhanced trail visibility. Similarly to our 29er wheeled BIG.NINE range, our classic BIG.SEVEN hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we could gain in over half a century of bike production and manufacturing. They represent the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan' symbolises.

    RACELITE 61 ALUMINIUM

    We use a minimum of 6061 grade aluminium on all our bikes. It’s particularly well suited to being shaped with our hydroforming and technoforming processes, which allow us to vary the wall thickness to create double-butted tubing and complex frame shapes. It’s also an alloy that welds easily, and once it has been carefully heat treated to maximise strength, it means we can create strong and lightweight bicycle frames for you to enjoy.

    TFS - TECHNO FORMING SYSTEM

    Manipulating the tube shape and thickness greatly impacts the appearance, weight and functionality of our aluminium frames. One technology that allows us to do that is TECHNO FORMING, where plain aluminium tubes get mechanically formed by using an external form and an internal metal core. The result, beautifully shaped tubes with varying wall thickness, ready to be used to create our technoformed aluminium frames.

    F-MOUNT

    Being able to turn your bike into an all-weather commuter that has mudguards and other fittings can be a real plus, in particular when riding on wet and perhaps muddy roads and tracks on a regular basis. To make fitting easy, some of our bikes are F-MOUNT equipped. These integrated fittings mounts make adding mudguards fast and simple. Please note that some bikes require model-specific mudguards.

    K-MOUNT

    When using your bike in an urban environment, where you might not always have the option to use a specific bike stand, a kickstand is an ideal solution to park your bike safely. Some of our bikes come with a neatly integrated K-MOUNT, which makes fitting a MERIDA kickstand (or any commercial kickstand) easy. And if you don’t want to have a kickstand and prefer the clean appearance of your frame, the K-MOUNT is neatly tucked away underneath your chainstay, difficult to spot if you don’t know it is there.

    C-MOUNT

    Similar to our F-MOUNT, where various fixing points for mudguards are part of the frame offering, the C-MOUNT equipped bikes have the fixing points for a rear rack already integrated, making fitting fast, simple and reliable. The C-MOUNTS are an additional feature that improves the day-to-day versatility by adding loading capacity to your bike, ideal for commuting and shopping trips. Please note that some bikes require model-specific rear racks.
