Sometimes a small push is all that's needed to open up a whole new world of exploration. The eSILEX 400 pairs a sleek, lightweight frame with versatile gravel tyres on 700c rims to the helping hand of the MAHLE ebikemotion X35+ hub drive motor and a 250 Wh battery to help expand your riding horizons. A fully-featured frame and carbon fork with plenty of mounts is ideal for overnight bikepacking trips or smaller adventures, while the smooth shifting and powerful braking of the Shimano GRX groupset with double chainset makes for reliable companions, on or off the road

If you are often looking for the off-road alternative when you are out on your bike or simply enjoy exploring the path unknown, then the eSILEX might be the perfect assisted bike for you. The rear-hub MAHLE system with integrated battery offers a neutral support level whenever your journey requires some e-motor assistance. You can even use an externally mounted 208 Wh MAHLE Range Extender to boost range. Similarly to the non-assisted SILEX, the eSILEX is available in the more rugged 650b or the more fast-rolling 700c set-up. Both versions come with gravel/off-road tyres for extra grip. A large number of fixing points on the frame as well as the fork, turn the eSILEX into an adventure rig without any fuss.

  • MAHLE ebikemotion X35+ hub motor gives natural feeling assistance
  • Triple butted aluminium frame with built-in 250 Wh battery
  • Sleek 'normal bike' silhouette and low weight
  • Shimano GRX drivetrain and hydraulic brakes
  • Fast-rolling 700c wheels with gravel tyres

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.

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.

IMAGE

WIRE PORT

MERIDA designed headsets that enable all control cables from the handlebar to enter the frame through the headset cover, creating a clean and uncluttered look, allowing for a lighter, stronger and more aerodynamic frame structure than with conventional cable ports. Depending on the model, the cables are run completely internally (including the bar and stem) or semi-integrated, where the cables enter the frame underneath the stem.
