  • The power to do more of what matters. That’s what the eBIG.NINE 400 offers. More fun when you’re riding off-road, with a powerful Shimano EP8 drive unit to help you up the hills. More time on the bike, with a 630 Wh battery that’ll keep you going for miles. More control, thanks to a Suntour suspension fork, chunky tyres and powerful Shimano brakes. More of everything except unnecessary weight, thanks to a high-quality aluminium frame that’s also got a lifetime warranty.

    Arguably the most versatile e-bike in our range, the tried and tested eBIG.NINE embodies the perfect balance of day-to-day usability and sporty leisure activity. It’s a bike that can handle serious off-road riding but can also handle the commute to work with ease - especially if you want to have some fun on the way. The high-quality aluminium frame integrates a choice of 630 or 750 Wh battery sleekly into the downtube, with a more economical frame featuring semi-integrated 504 Wh battery on some models. All feature powerful and smooth Shimano drive units that will power you up any hill. Ready to be equipped with mudguards and even a side stand (or available as the EQ fully equipped version), the eBIG.NINE will help you make the most of any situation.

    To reduce production and delivery times, we are sometimes forced to make last-minute specification changes. Please be aware that those changes might not be reflected on these product pages and images.




    Our proven high-end aluminium (6066) is extremely light and durable. Using triple butted wall thicknesses and hydroforming technology, we can tune the aluminium tubes to give the best possible stiffness to weight ratio.



    Tubes are inserted into negative moulds and a hot emulsion of water and oil is forced through at pressure, enabling them to be formed into complex shapes.



    Our X-Tapered headtube offers the space for a tapered fork to be fitted. Tapered forks offer superb stiffness and precise and deliver confidence-inspiring steering.



    Sometimes called ‘double pass welding’, a second pass over the weld gives a clean organic look to the frame. At first glance, you will be convinced it is carbon.



    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.



    Cables, housings and brake hoses are clamped under tension to prevent rattling when the trails or roads get rough. All inlets are completely interchangeable to deal with Di2, hydraulic hoses, brake cable and gear cable housings etc.



    Bikes/frames with the symbol ‘Di2 Ready’ are prepared for the installation of Di2 technology with battery mounting in the seat post or within the fork steerer.



    ‘F-Mount’ equipped bikes have integrated fittings for mud guards (some bikes require model specific mud guards), making fitting fast and simple.



    Integrated mount on the chainstay to fit a MERIDA kickstand (or any commercial kickstand).



    ‘C-Mount’ equipped bikes have the fixing points for a rear rack already integrated (some bikes require model specific rear rack), making fitting fast, simple and reliable. 



    Sophisticated shape only possible due to casting technology, creating an integrated appearance as well as an extremely strong connection between the E-bike motor and frame for improved performance and reliability.



    Twist lock mechanism that is located at the top end of the 'Energy Guard' battery cover, for easy locking and unlocking of the protective internal battery cover.
