The electronics are dispersed over the whole bike. frontlight, backlight, camera's (I'm thinking 3 or 4), integrated mapping,, electronic lock, possible electric steering make it impossible to put all tech into a detachable unit. It's simply out of the question for a well-designed bicycle. I can see it adding some value for current bicycles though.
For the frame I probably want aluminium, because it's cheap and light enough. Shocks are not needed as my country has excellent biking paths. For most other countries shocks don't add too much value, especially not when using the bike in an urban environment. Then they are just maintenance-prone weight-gainers.
