Integrated ROAD e-Bikes with Hidden Motors: game changer or just a massive cheat?

We look at latest integrated Road e-bikes, with "hidden" motors and concealed batteries: these bikes look like regular road bikes but offer power boost when needed (up to 200mins, 250w ave, 400w peak). But do you prefer old school real cycling? Indeed are ebikes a good idea for regular cyclists or will they destroy your work ethic and training gains? Whatever your view on ebikes you have to admire the technology.
