I'm doing a new build soon (to sell), and the one thing that annoys me is always how messy the cockpit looks with all the cables going everywhere. So can you drill into the bike to run the cables through the tube? and also how would you go about actually routing the cables?
 
Well you can, just use a wire fisher or a nail on a string use a magnet to drag it between. Now should you be doing this? Almost absolutely not, and especially so if you plan to sell it, holes in frames are not to play around with.
 
i cant see drilling two small holes into the frame being an issue. expensive premium ebikes have their wires internally routed also. a couple probably obvious points...

- want to drill the holes so water does not get stuck in the tube
- need to either remove the sharp edges from the hole really well. you be actually surprised that in some of the expensive ebikes ($4-5k) that the plastic coating on the wires and wire themselves do get damaged after some time because an extra 5-10 mins of effort wasnt done

It's not the drilling of holes, it's the drilling of holes by someone who probably doesn't know where or how the beat way is..
 
The thing is good bikes have machined tubes, many bikes have tubing that is thicker at the welds and tapers to thinner wall towards the middle where there is less stress not plain tubing. I would assume bikes with in frame cable routing have tubing that is thicker where the cable enters and exits the tube. There is more engineering and stress analysis put into better frames and internal routing is part of that.
