Just got a trailer hitch installed by Curt at a local U-Haul. It will be used for a bike rack system by Thule. I found this is one of the best set ups for carrying bikes long or short distance.
The rack can be found here
http://www.thehitchstore.com/class-i-receiver-hitch-p-2096.html I bought mine direct from U-Haul since they can order almost any brand, of course they put their name on it Curt makes them for U-haul.
I will post a photo with the rack on the hitch later at least you can see how it looks on a Cube.

Highly recommend having it installed by U-Haul or someone with the right tools and a ramp. Drilling is necessary on the frame to make two holes on each side larger for spacers for the hitch. The exhaust had to be removed to fit the hitch in properly.
