HI,
We have hybrid bikes and have bought this rack....
Saris Bones RS Rack for £152.99 | Saris Car Racks | Cycle | Wiggle
It fits the OH BMW 6 and is supposed to fit the Mini too - although as yet we haven't tried it.
It was great on the 6 - we took the bikes to France last month and had no problem. Once set correctly it's easy to fit - one person could do it.
