    "A carbon XC bike that makes light work of the longer rides...As a package the Merida BIG.NINE 5000 delivers good performance from its carbon frame and RockShox fork, and both feel good enough to make upgrading the rest feel worthwhile."
    - Matt Page

    Off Road CC

    The Merida Big Nine 5000 is a high-quality hardtail which combines aggressive agility with smooth stability to form an excellent modern XC bike. The CF3 Carbon frame is light, stiff and tough so that you can get the most of every ride, paired with a RockShox Reba RL Fork (51mm offset) with 100mm travel and remote lockout. It is designed with Merida's race-proven geometry with a shorter top tube and a higher head tube for a slightly upright position that gives you improved visibility.

    A great frame needs to be matched with a great groupset and the 1x12 speed Shimano drivetrain offers smooth shifting and the simple efficiency of the 1x is now standard on all good mountain bikes. This will give you the range of gears you need to tear up the trails on the Maxxis Ikon 29" tyres and Merida Expert CC Rims. The Shimano M6100 2 piston hydraulic disc brakes give you the control you need with all of that easy speed, you can attack every corner and descent with confidence. The Merida Big Nine 5000 is a capable climber which comes into its own on longer rides thanks to the carbon frame and excellent components.

    Modern Trail Geometry

    Our carbon and LITE aluminium models feature a long 422 mm reach, steep 73.5° seat angle, slack 70° head angle and an 80 mm stem (BIG.NINE – M), affording the BIG.NINE next-generation XC geometry.

    Dropper Post Ready

    All models down to the BIG.NINE LITE frame level feature a 30.9 mm seat post, the enhanced connection area increases the strength around the top tube/seat tube join and allows the option of fitting a dropper seat post. 

    Classic Hardtails

    Hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we were able to gain in 48 years. The BIG.NINE range symbolises the symbiosis between modern frame technology, attention to detail and craftsmanship.

    About Merida

    In September 1972, Ike Tseng (1932–2012) a brilliant engineer and visionary founded MERIDA. While visiting the USA, Ike saw a sign in a bike shop that stated refusal to repair any Taiwanese bikes, due to the unfavourable quality. As a result of this he set out to fulfil his dream of high quality bikes made in Taiwan and formed the MERIDA Industry Company Ltd.

    The MERIDA name has three syllables Me-Ri-Da and it is the company’s intention to manufacture beautiful, high quality bikes that enables everyone to reach their destination enjoyably. MERIDA created a world-leading bike factory but Ike still wasn’t satisfied, so in 1988 the MERIDA brand was launched. Ike’s vision is still very much a part of MERIDA, manufacturing all kinds of bikes from children’s bikes to world-class professional road and mountain bikes for the Bahrain- MERIDA team riders. Everybody has a different journey, and everyone can benefit from a MERIDA.
