How should I transport Cannondale Bad Boy 5 INSIDE a BMW 4 Series Coupe? So, I have a Cannondale Bad Boy 5 and I'm LOVING it.



I'd like to understand how to transport it. I have 2014 BMW 4 Series coupe. Even though I folded back seats (to maximize trunk storage), bike won't fit there (well at least not all the way anyway), so I gotta take one of the wheel off. The wheels are 700c discs and the fork is a Cannondale Lefty fork (i.e. attaches only on one side). 

my main concern is since i cannot easily take off front wheel due to lefty fork and i can use quick release to take the rear wheel off; What's better way to handle derailleur (without ruining your cloth, car, etc).

Ideally I'd like to:


use quick release to remove rear wheel,
place chain into some sort of container (suggestions?),
place bike along with separated wheel (derailleur up) inside of the car, 
go to wherever, and revert procedure.
None of the other answers deal with the OPs desire to keep the bike inside the car, i.e. not on a rack.

To put the bike in the car, you have to take off at least one of the wheels.

Pedro sells a "chain keeper" which is designed to keep the chain on or near the derailleur when the rear wheel is off:




This should help you considerably (along with old towels and maybe a moving blanket) to put the bike cleanly in the car with the rear wheel off.
