Hand-picked for this exact result — no generic lists.

Trunk, roof and hitch are three different sports — pick honestly.

Trunk: wheels off.
Front wheel off and the bike nearly halves in awkwardness.
Roof: mind the weight.
75 kg total system limit — e-bikes add up fast.
Hitch: easiest daily.
Low loading, rear access, small fuel penalty.
Lock everything.
Racks need locks; bikes need locks on the rack.

One concrete case, with the assumptions spelled out.

~840 L × 60% ÷ 500 L gives 1–2 bikes wheels-off — a hitch rack carries 4 with less Tetris.
