So my brother's wife wants a cruiser, and that means my brother does too, so they can ride together. He's REALLY into roadbikes, has a Felt that he paid more than I've ever paid for a car for, and has a thule roofrack type rack with the trough for the back tyre, and the brace/skewer set-up for the fork. He wants to know if this will be sufficient for a cruiser, or if he should just get a trunk-mounted one, like I have. Any ideas?
