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.

Technology

PROLITE 66 TRIPLE BUTTED ALUMINUM

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.

IMAGE

HFS - HYDRO FORMING SYSTEM

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.

IMAGE

X-TAPER HEADTUBE

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.

SMOOTH WELDING

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.

INTERNAL CABLE ROUTING

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.

INTERNAL CABLE ROUTING
IMAGE

DOWN TUBE EXIT

Ensures that internally routed cables and wires can’t move freely and remain easily accessible for servicing.

IMAGE

F-MOUNT

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

IMAGE

K-MOUNT

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

K-MOUNT
IMAGE

C-MOUNT

‘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.

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.
