Here it is. A quick and easy - and very tongue-in-cheek - guide to determining if you live in a city with bike culture. All from the good people here at Copenhagenize.com.
1. ”Fixed gear” is something than happens after you take your old Raleigh down to one of the 20-30 bike shops in your neighbourhood to have them look at ”broken gear”.
2. If a car honks at you in traffic, you hardly notice. Instead it makes you think that it's been a while since you took your kids to the park to feed the ducks... Hmmm... maybe this Sunday?
3. You think nothing of riding home in 35 degree heat, with your four year-old on the bike seat, two bags of groceries dangling on your handlebars, talking to your partner on the phone about dinner - all the while heading up a steep hill and STILL being able to growl ”Stay on the right!” in three languages at the weaving, gasping tourists on their rental bikes whom you just flew past as though they were carved in stone.
4. When you feel yourself start sweating on the bike lanes on your way to work... you just ride slower. And if the forecast is for hot weather, you leave for work a bit earlier so you don't have to ride so fast and get too sweaty.
5. The only place you ever see Lycra or spandex is in old Jane Fonda workout videos or on joggers in the parks.
6. And you're quite sure that Gortex is that guy who plays midfield for Bayern München.
7. When your bike breaks down and is in for repairs you take your other bike, or you take the train or bus. Even though your car is parked out front.
8. Of the few people who wear those helmet things in the world's safest cycling nation, only a handful are actually wearing them correctly and many just carry their helmet in their basket.
9. The odd-person out in your circle of friends is the one who has never fallen off their bike while riding home drunk. You mock him/her regularly.
10. You have, at one time or another, checked to see if your clothes match your bike.
11. You and your friends have repeated discussions about which bike repair shop in your neighbourhood is the best for price and service.
12. When you see somebody with rolled up trouser legs you think, ”what a shame that fellow can't afford a chain guard”. You consider rolling up next to him at the next light to give him some money.
13. You don't even know that you live in a ”bike culture” and have never used the expression. You just ride.
14. You use your time waiting at a red light in bicycle rush hour with over 100 other cyclists to check out new fashions. ”Wonder where she got those shoes? Cool sunglasses on that guy... must be Prada.”
15. Your entire wardrobe can be classified as ”cycle wear”. Espeically those stilettos from Christian Louboutin or your new double-breasted trenchcoast from Tiger of Sweden.
16. When the odd motorist cuts you off you fix him with an icy stare and shake your head in pity before riding off and forgetting the whole episode 50 metres farther down the bike lane.
17. You find rust on bicycles to be charming and aesthetic. Shiny new bikes are somehow gaudy.
18. It takes you over fifteen minutes to find your parked bike at the train station.
Addendum: 14 June 2010: Read this interesting criticism of the Copenhagen Wheel from Steven, Architectural Historian and cyclist: Two thumbs down for The Copenhagen Wheel. The City of Copenhagen and MIT have been working on a project for a while and it was finally revealed here in Copenhagen this week. The Copenhagen Wheel. An electric assist device on a back wheel that is also filled with a host of functions. Smart, responsive and elegant, the Copenhagen Wheel is a new emblem for urban mobility. It transforms ordinary bicycles quickly into hybrid e-bikes that also function as mobile sensing units. The Copenhagen Wheel allows you to capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost. It also maps pollution levels, traffic congestion, and road conditions in real-time. 
The Copenhagen Wheel with Lord Mayor Ritt Bjerregaard in the background. Now I certainly didn't write that, above. They did. Of course they did. The most interesting aspect of the gadget, in my opinion, is that it can be retrofitted onto existing bikes. That's geekspeak for "take off the wheel you have now and put this new one on". It might also be an interesting idea in that it eliminates the need for many electric bikes and all the large, cumbersome batteries that are so difficult to dispose of. Simple, elegant and symbolic. I just hope you can get versions of the wheel in different colours to match your existing bike. In Copenhagen rust-coloured wheel hubs would be a big hit. Oh, except it weighs 15 kg. Nevermind. We also have to question the wisdom of e-bikes in cities. Are we supposed to send fast moving, silent machines into mainstream bicycle cities like Copenhagen where the average speed for Citizen Cyclists is 16 km/h? We have enough problems with scooters. Do we need SILENT scooters flying past? If you think about it, everything we need for cycling in a city has already been invented. Over a century ago.
