eBIG.NINE 475

 

The power to do more of what matters, whether you want e-assisted off-road fun or a hassle-free commute, all wrapped up in a sleek, high-quality, fully integrated frame.

The power to do more of what matters. That’s what the eBIG.NINE 475 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 high-capacity 750 Wh battery that’ll keep you going for miles. More control, thanks to a SR 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.

PROLITE 66 TRIPLE BUTTED ALUMINUM

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.

IMAGE

HFS - HYDRO FORMING SYSTEM

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.

X-TAPER HEADTUBE

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.

IMAGE

SMOOTH WELDING

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.

IMAGE

INTERNAL CABLE ROUTING

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.

IMAGE

SMART ENTRY

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.

DI2 READY

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.

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.

IMAGE

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.

IMAGE

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.

CASTED MOTOR BRACKET

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.

ENERGY GUARD TWIST

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.
