The EMX-1 2013 Road Bike features CL+ and OSR technology. CL + // Carbon Laminate : Carbon fibre bikes are made using sheets of carbon fibre, and these are built up in layers one on top of the other. The Carbon Laminate process, developed by and for Eddy Merckx cycles, assemble the sheets together in ways that maximise the strength and rigidity of the resulting frame. The result? Optimized performance, comfort and weight. OSR // Optimized Structural Reinforcement: Advanced high modular stiffness fibres are used in combination with high-strength fibres to achieve unparalleled performance. They are used in different strategic areas of the bike, as and when required. The front fork for example needs both for optimum weight reduction and improved stiffness and feel.
I would suggest the most suitable size given your height would be the 48cm frame of this bike. The Eddy Merckx sizing are unique so I would suggest test riding the bike as the best way to select the correct size which can be done by contacting your local Evans Cycles store.
