Fast, refreshing, and efficient ... bronchs

I love Ibike's list giving 60+ advantages in cycling.  A bike can take you to the heart of a city, in this case Bath, England.

It would be worthwhile putting the advantages in order of preference, so how about this for starters:

1. It's often faster cycling short journeys or in cities [No 8]
2. The exercise and freedom refresh body, mind, and spirit [No 10 & 13]
3. I agree that a well maintained bike can give years of service at little expense to the environment [No 1 & 42]

But there's one disadvantage because cyclists often have to breathe in polluted air.  What if they had clean air to cycle in?  The cycleways could be the lungs of a city, its bronchs.

Here's to real investment in clean cycling,
