700c wheel gravel eBike with Shimano GRX400 2 x 10 drivetrain powered by MAHLE ebikemotion 40Nm hub motor and 250Wh internal battery.
 
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 as well as offering 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.
