Urban bike riding as training for tree-skiing season:

Riding (er, snowboarding) through trees / down chutes requires you to make pretty quick decisions at decent speeds.

(Via teendrama :: hello my name is dennis.)

Bicycle riding has a lot of inputs. Curbs, people, dogs, oncoming cars, driveways, other cyclists, waters, leaves, etc.

This rapid flow of incoming stimuli requires the mind to analyze a lot of data and to make rapid decisions to prevent bad outcomes. Falls, slops, slides, flips and other injuries to people and property.

The ability to make correct decisions quickly is important in life and in business.
