  • Joining together urban practicality with the willingness to explore is no easy feat, but the eBIG.TOUR 400 EQ does just that, with the latest Shimano EP6 drive unit giving you smooth yet powerful assistance whenever you need it. Large volume tyres, a suspension fork and mountain bike inspired geometry deliver capable and confident handling whenever you want an adventure, but the low-step-through frame design with integrated 630 Wh battery and generous standard fit equipment including mudguards and lighting have your everyday needs covered, so there’s no need to compromise.

    Are practicality and excitement mutually exclusive? We don’t think so - and neither does the eBIG.TOUR. It’s a reliable day-to-day companion for riding to work that’s equally happy taking you on big adventures off the beaten track, thanks to a winning combination of mountain bike inspired geometry with low step-through frame practicality. A powerful and smooth Shimano pedal-assist motor is integrated cleanly into the aluminium frame, while a suspension fork and high-volume tyres provide comfort and safety. Add in standard fit mudguards, racks, lighting, wheel lock and a kickstand plus long-lasting 630 Wh battery and you’ll realise you’ve got the best of all worlds.

    When creating high-end aluminium frames, we use our proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

    To get the most out of an aluminium tube in terms of shape or varying wall thickness, we apply various forms of manipulation. The most complex but also the most effective is hydroforming, where an aluminium tube is inserted into a negative mould, and a hot emulsion of water and oil is forced through at pressure. The end result is a perfectly shaped aluminium tube that enables us to create beautifully crafted and lightweight aluminium frames.

    Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

    This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

    On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

    Many of our frames offer internal cable routing, where the gear and brake cables are run through the frame for maximum protection and a clean look. Some internally run cables can rattle when riding over uneven surfaces, but our SMART ENTRY system prevents this from happening. Cables, housings and brake hoses are clamped under tension to prevent noisy cable movement. All inlets are completely interchangeable to deal with any kind of cable or wire.

    Shimano's Di2 electronic shifting system offers fast, smooth and reliable shifting. In particular, in the road world, it has proven itself as the primary choice when top performance is at the top of the agenda. With that in mind, we have a broad selection of performance road frames that are Di2 READY and can accommodate the electrical cable, battery and other little tweaks that the system requires.

    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.

    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.

    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.

    The e-bike motor mount has a sophisticated shape that is only possible to create with casting technology. Casting this piece allows us to create a complex yet lightweight shape that gives an extremely strong connection between the motor and the frame for improved performance and reliability. It also gives the bike and motor a smooth and cleanly integrated appearance.

    A two-component battery cover fitted to bikes with an internally mounted battery. It protects the battery from dirt and moisture, with a softer outer layer that absorbs impacts. An easy-to-use twist lock mechanism secures the cover in place without the need for tools with a simple and light action that makes it easy to access the battery for off-bike charging, but prevents the cover from falling off, even when riding on the roughest terrain.
