Uplink, with the Civic the rear seats fold up cinema style, so you can get a couple of bikes in the rear footwell with wheels off, leaving the boot for camping gear etc.
Or should I look for an estate? Yes!
If you go for a Mondeo, you might as well get the estate. Its no longer than the hatch, but is easier to park as you don't have to guess where the boot ends, more space in the boot due to different suspension, there is no lip to the boot, and the light clusters don't narrow the opening.

The Octavia estates boot, although large, is considerably smaller than the Mondeo. Could get four bikes stacked in the boot of the Mondeo estate and still room for five adults, but the bulkiest of the bikes (Fat Possum with triple clamp Maveriks) wouldn't go in the Octavia estate by itself without folding half the rear seats and it was still tight.
Focus...you can get a Mondeo for the same money.
