Just bought a Rail7, seem like an accident waiting to happen with the exposed wires under the Armor plate. I am on my 2nd Armor Plate and cracked in in two days of riding. Bad design, same weak spot. The wires to the motor are not protected, who design something like that. Trek really needs...
Smart fix would be to redesign the area that is weakest, as shown in the photos above. 2 plates that crack at the same exact point. They seem to be poured ejected molded aluminum. Ive seen the other plates and they do not seem that much better. Either that or just lower the replacement price...
