I find my motorcycle gear is designed to keep the rider warm in 50mph winds (i.e. riding on highways). I has actually been very useful bicycling - leather jacket, mittens, boots.

I used to find bicycling cold around 25-28 F, but after finding the motorcycling gear I had no trouble commuting to work on 8-11 F days. (20-40 minute commute). I wouldn't choose to wear much of this clothing in the summer.

I did find a reflective vest good for both the bicycle and motorcycle. It has very large reflective stripes, but is not heavy enough to block breeze.
