I have a 52cm bike... I drive an Accord Coupe... as I have been too cheap to buy a bike rack... and I don't want someone trying to steal it...

I just drop the back seats down... take the front wheel off the bike... and I put the bike in with the forks in first... they fit perfectly between the two seats...

Have you tried to fit the bike in the trunk? Do your seats fold down?

And if you have multiple bikes (I can't remember???).... then forgive me for the suggestion.
