The rear seats dont fold down so its not the most practical of things unfortunately. It does have ski hatch but I think you might be pushing it getting a bike through
In all seriousness though, I haven't ridden a bike in a long time, the boot on the coupe is pretty chunky and the opening is quite wide. I dont think a bike would have any problems going through the gap, somehow I think you would need to remove both wheels to actually get it in though given that the rear seats are fixed.
Comments like this are exactly what I was refering to in my earlier post, its blatent hatred with no justification or cause. Would you actually rather push a broken down Focus however many miles home rather than arrive in comfort in a fully working Astra or Insigna? Dont be so daft.
