Best Bike to ride before a good listening session

I'm on a tricked out Giant advanced TCR. at 14lbs (yes actual weight on a scale) it is a pleasure in the Bay Area hills

Serotta Legend ST or my Harley Davidson Street Glide (if I'm feeling lazy).

Well, despite the cooler and wet weather I have managed to get a few rides on my new R3. All I can say it is amazing. Fast, rigid, light, and surprisingly comfortable. Just sweet going up hill (under 16 lbs loaded). And all the roads feel like they were newly paved, whether they were or not. Beautiful in the turns. Love the compact crankset. No complaints, other than it took 4 months to get. see picture on my system page

If your on 2 wheels you should know.
