Much has been made of late about the U.S. devolving into a country divided.

It’s serious stuff.

Taking a lighter approach, Appleton author Mike Magnuson has analyzed cyclists divided and crafted a new book called “Bike Tribes: A Field Guide to North American Cyclists.

Much as the political order has been sliced into conservative, liberal, tea-party and socialist, Magnuson parses the biking world into The Commuter, The (Serious) Roadie, The Overwhelming Majority, The Vintage Lover and The “Fixie” Rider.

Like a political pundit, he skewers each, but with humor.

A few examples: The Commuter rides 6 miles to work every day, even in the rain; only employee to use company bike rack; secures briefcase with bungees; believe commuting helps them think.

The (Serious) Roadie is decked out in spandex; pencil-thin arms; often thinks they’re the next pro; despises triathletes and loves to bicker on web message boards.

And the Vintage Lover prefers 1960s bikes, considering them works of art; likes to ride to social functions or the farmer’s market; well-dressed; hopes people are watching them.

Magnuson will be sharing his book and his humor during a book-signing event at 6:30 Tuesday night at Crank Daddy’s Bicycle Works, 2170 N. Prospect Ave. Bike Tribes, Magnuson’s fifth book, is published by Rodale Inc., and you can check out his blog here.
