Contact Local Shop

The dream ticket when discussed in the Merida UK office. A gravel bike with motor assistance, allowing you to go further, tackle more and generally just grin a lot.

MAHLE's ebikemotion system uses a 40Nm rear hub motor powered by a fully integrated 250Wh battery hidden in the downtube.

The low system weight combined with a carbon fork and sophisticated aluminium frame means the bike also feels lively without power assistance. There is almost no drag at all from the motor when it's not engaged.

The system has an iWoc button for controlling support levels and a sophisticated app provides an opportunity to adjust the riding feel and also offers post-ride analysis features.

The frame has mounts for mudguards and rack and a neat hidden kickstand mount. Cable routing is through the frame with cables entering through a specific headset cap to keep the cockpit neat.

The eSilex can be run with either 700c or 650b wheels.

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.

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

DOWN TUBE EXIT

DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

IMAGE

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

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

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.

IMAGE

WIRE PORT

All control cables like gear, brake and dropper post cable enter the frame through a specifically shaped headset cap, cleaning up the cockpit area while also keeping them out of harm's way. Only the internally routed cable for the rear shock lockout enters the frame directly into the top tube for extra smooth lockout action.
