The bicycle has been with us for over a century, and in that time has evolved into a variety of forms and attracted wide variety of riders, all united to some degree by their love of fast, human-powered transportation. The internet has been around for a few decades, and in that time has managed to divide the cycling world into a wide array of disparate and occasionally bitterly-divided factions.
Every cycling blog, forum and chat room, as well as just about any news article even vaguely related to cycling will draw out these folks en masse, each one of them ready to offer their take on the One True Way to enjoy the use of their two-wheeled conveyance.
While it's impossible to keep up with the subcultures and fads that are rising and falling every moment on the internet, I've tried to compile a list of some of the most notable sorts. It's also worth noting that there are many hybrid cyclists, who show traits of one or more of these breeds. Please note that, while I've listed these various species using male pronouns for the sake of brevity (English being lacking in gender-neutral words to describe humans) each type has its female variant as well.
The Weight Weenie:
Rides a road racing bike, although the chance that he or she actually races is only 50/50. Will spend hours poring over spec sheets to find the way to shave two paper-clips'-worth of weight off their bike. Will dismissively refer to other forum members' 20lbs bikes as "tanks" and sneer at the idea of carrying anything so bulky as a lock or multitool. Usually buys parts online and upgrades compulsively.
Quote: "Well, it's an OK bike, but with a 32-ounce wheelset you might as well be dragging a coffee table behind you."
The Bicycle Creationist:
To the Creationist, bicycle technology began and end at some fixed date in the past, usually somewhere around 1970. Since then, everything about cycling has deteriorated, including frame materials, shifting quality and even the clothes riders wear. What modern riders might consider "dangerous flaws" in some older equipment, the Bicycle Creationist refers to as "endearing quirks." Hates clipless pedals and integrated brake-shifters with a passion and considers Rivendell Bicycles to be a bit "newfangled"
Quote: "Well, it's true that those stems did snap off and cause fatal crashes on a couple occasions, but you have to admit they were a lot better looking and had much more SOUL than these modern gadgets."
The Dutchie is a hardcore transportation cyclist who believe that "proper" cycling can only take place on upright city bicycles whilst wearing street clothes. Will constantly talk up how much better bicycle culture is in European cities such as Amsterdam and Copenhagen, and sneer at people who ride their mountain bikes to work. Will often spend upwards of $1,000 to import the European equivalent of a Schwinn Varsity.
Quote: "Yes, it takes me and two friends to lift my bicycle over a curb, but in in Denmark they have 43 miles of dedicated bicycle paths leading to each picnic table, so I would never have to go over a curb to get to a public park."
It's a dangerous world out there, and Safety Man is prepared for the worst. He never gets on a bike without a helmet, hi-visibility vest, gloves, protective eyewear, at least four taillights, a 300-lumen headlight, a backup headlight, pepper spray, a safety whistle, non-slip footwear, raingear (with reflective strips) a safety flag and six forms of ID. To Safety Man, "reasonable safety precautions" involve getting ready for "Mad Max" road scenarios.
Quote: "You can quote all the statistics you want, but if you're not wearing a reflectorized helmet with an emergency locator beacon, you're nothing more than an organ donor in training."
Anti-Helmet Guy does not like to wear a bicycle helmet when riding. He really, really does not like to wear a helmet. However, instead of simply saying "I don't think my activity is risky enough to warrant protective headgear," Anti-Helmet Guy will, at the drop of a (non-protective) hat reel off a list of statistics, factoids and anecdotal stories that will tell you under certain circumstances, when the moon is right and the wind from the Southwest if you land just so and are moving at a particular velocity in relation to a particular type of blacktop at a certain temperature a helmet just might result in slightly worse fatal injuries than the fatal injuries you would have incurred while not wearing a helmet in the same circumstances, therefore no one should ever wear a bicycle helmet.
Quote: "Antarctica has no mandatory helmet laws, yet in 2009 there were no fatal cycling-related head injuries reported on the entire continent, see how forcing people to wear helmets puts them at risk?"
The Gaspipe Ironman:
The Gaspipe Ironman is the polar opposite of the Weight Weenie. He not only isn't worried about how heavy his bike is, he's proud of it. His greatest cycling-related joy is to describe how many lycra-clad road racers he's passed on tough climbs while riding a $79 girls' cruiser with a rusty chain he bought from the local department store 3 years ago. If the Gaspipe Ironman is to be believed, on a bike that actually fit him and had working gears, he'd have won last year's Tour de France by four hours. Fortunately for the cycling world, he has a 75 lbs Roadmaster to hold him off from a Championship Jersey monopoly.
Quote: "The local professional road racing team has learned to fear the squeaking of my unlubricated chain."
This cyclist won't buy so much as an inner tube without logging on to a cycling forum to ask if a particular brand is any good. Every day he'll post a question on some trivial bike-related matter, often prefaced by "the guy at my local shop told me I should do this, but..." The input of a dozen anonymous voices on the Internet are of more value to the Poller than any individual he could actually meet face-to-face. If the Poller's query is not answered on a cycling forum within 15 minutes, he will quickly reply to his own discussion thread with "hello?" or "does ANYBODY know anything about this?" The Poller is often most easily satisfied by running a Google search of his question and copy/pasting the results.
