Ohio State bikers should be ‘extra careful’ as fall and winter loom [The Lantern]

The first month of classes was riddled with bicycle-related accidents on and around campus, and as the leaves begin to fall, bikers will have even more obstacles to dodge.

Bicyclists face various challenges to safety when riding in the fall and winter, including wet or slick roads, ice, snow or wet leaves on the roads, potholes and less daylight.

Meredith Joy, executive director and founder of Yay Bikes!, a nonprofit organization that promotes bicycling as an alternative to driving in Columbus, said there are several factors that cyclists should be aware of when riding in the winter.

“Wet leaves can be really slippery, wet leaves can also obscure things underneath on the road, and potholes can all lead to crashes,” Joy said. “Reducing the air pressure in your tires a little bit can be helpful in accommodating for the road conditions.”

Despite the additional obstacles with the change of seasons, NickChenoweth, a third-year in mechanical engineering, said he expects the number of bike-related accidents on campus to decrease in the winter.

“I feel there are a lot of people that ride their bikes right now that will not be riding in the winter time,” Chenoweth said. “There will be less cycle traffic, and therefore probably less accidents.”

PSU research makes connection between bike-friendly and bottom line -@yaybikes gets it! [bikeportland]

Researcher Kelly Clifton at a presentation at City Hall today.

Portland State University researcher Kelly Clifton has shared more detailed data on her research into how mode choice impacts spending behaviors. After talkingto Clifton at the outset of her research and then sharing some initial findings back in July, I learned more about her findings at the Bureau of Transportation'smonthly Bicycle Brown Bag discussion series held at City Hall today.
According to data from 1,884 surveys taken outside various establishments, non-driving customers — those who show up by bike, on foot, or via transit — are often more valuable in terms of dollars spent than customers who arrive in a car. This data flies in the face of the often heard perspective that automobile access should be the highest priority to ensure business success.

Is this thing sexist? Introducing the “Bike Test” [Taking the lane]

This post is drawn from a presentation I developed for the first-ever National Women’s Bicycling Summit in September, 2012.
As the influence of women grows across all types of bicycling, there has beenquite a bit of debate about the representation of gender in everything from ads to advocacy campaigns, race tracks to board meetings. Is that photo of a sexy woman on a bike sexist, or is it empowering? Objectifying, or compelling? Tokenizing, or inclusive? Is it different if the photo was taken by a woman? What if the woman depicted is an avowed feminist? Does this mean we are never allowed to depict women wearing skirts and heels? These discussions tend to get frustrating, in part, I think, because we don’t always have a shared idea of what these terms mean.
I saw the need for an analytical tool that could be used by both media creators and consumers to evaluate images of women in bicycling. So, inspired by theBechdel Test for women in movies (still as relevant today as it was in 1985), I created…

The Bike Test:

Here are the criteria:

1. Are women present or represented at all?
2. Are the women presented as active subjects rather than passive objects?
3. If the gender were reversed, would the meaning stay more or less unchanged? (Or would the image become hilarious?)
Going down this list is a surprisingly effective way to evaluate inclusiveness of a wide range of representations and entities, including advertisements, movies, news coverage, organizations, corporate or nonprofit boards, events, conference lineups, curricula…whatever happens to be in front of you. And needless to say, this all applies well beyond bicycling.

The bicycle party known as Critical Mass turns 20 on Friday. Hundreds, possibly thousands, of riders in all manner of dress and - if recent history holds true, no dress at all - will band together for a commemorative, congestion-causing cruise through downtown San Francisco.
The event comes at a time of enormous growth in the number of people who are engaging in what 20 years ago was still considered rebellious behavior - commuting by bicycle.
Chris Carlsson, the Critical Mass spokesman, said he expects 5,000 to 10,000 riders on Friday, more than 10 times the number of riders who routinely participate.
"It's going to be a gigantic mess, but it is going to be fun," Carlsson said.

GearJunkie Top 10 Gear from Interbike

The GearJunkie crew is back from five days of bike-centric living at the Interbike Expo trade show in Las Vegas. We rode, demo’d equipment, watched a race, and saw loads of great new bike gear that will be coming to market later this year and early in 2013. As a bonafide bike junkie, here are my top 10 picks from the show. —T.C. Worley
#1 — SRAM XX1 Group. A first of its kind, this group uses a 1×11 system (one front chainring, an 11-speed rear cassette) that offers similar gearing range as a double chainring setup. You cut weight, lose a front derailleur, and end up with a more simplified system for cross-country and all-mountain riding. TheSRAM XX1 Group will be sold in several configurations when it comes to market next month.

Less is More: SRAM 1×11 Mtb Groupo
#2 — Salsa Warbird Ti. Just when you thought you’d seen every bike genre, Salsa adds another. The Warbird model is specific to road racing on gravel. (Think the Almanzo 100, as one example.) Before you assume it is just a cyclocross bike, I’ll explain that the geometry involves a longer wheelbase, a lower bottom bracket, and a more upright position for long days in the saddle. Shoot down a high-speed, slowly banking gravel hill and you’ll know why this bike is different — the operative word is “stability,” Salsa cites. Highlights include a titanium frame, ENVE carbon fork, and disc brakes. Offered in a less-expensive aluminum version as well, either Warbird model might just help you get off the blacktop, turn down a country gravel road, and see that pavement is overrated. Price is TBD.

Photos of Famous Authors and Their Bicycles [Flavorwire]

It’s the height of bike riding season here in New York — it’s no longer so hot that you can’t do more than duck from air conditioned shop to air conditioned shop, but it’s still beautiful, and as the air continues to crisp, the cyclist will be out in numbers. And hey, in another life, one of them might have been Leo Tolstoy. We spotted this delightful photo of Leo Tolstoy and his bicycle — he learned to ride at 67! — over at Open Culture, and we were intrigued. Bike riding seems like an appropriate pastime for authors (all those bike-powered book tours and long lazy afternoons), so we thought we’d hunt around to see how many other famous writers liked to zoom about on two wheels. Click through to check out our gallery, and let us know if we missed your favorite snap of a writer on a bike in the comments.

Cyclists who are a law unto themselves make a recipe for anarchy [theguardian]

Cycling in New York City
Cycling in New York City. Photograph: Alamy
Walking just a mile from my apartment to my parent's house in Brooklyn,New York on Monday evening, I witnessed three bicyclists riding in an alarmingly dangerous manner: one nearly ran me over as he turned on a red light while I crossed a street; one was going the wrong way on Flatbush Avenue, Brooklyn's busiest street; and one forced me to wait to cross on a green light because he ran a red without even slowing down, much less stopping. By the time I was safely indoors, I had decided that New York City ought to start much more aggressively enforcing the traffic laws on bicycles.
So, imagine my surprise when I got to my parents house, opened theNew York Times Sunday Review, and saw that Randy Cohen, The New York Times Magazine's erstwhile "ethicist", had written an op-ed in favor of these irresponsible behaviors. To be sure, Cohen did not endorse each of the foolish choices, but his distinctions between the ones he proudly engages in and all others are pure sophistry. Cohen writes:
"I routinely run red lights, and so do you. I flout the law when I'm on my bike; you do it when you are on foot, at least if you are like most New Yorkers. My behavior vexes pedestrians, drivers and even some of my fellow cyclists …
"But although it is illegal, I believe it is ethical … I roll through a red light if and only if no pedestrian is in the crosswalk and no car is in the intersection – that is, if it will not endanger myself or anybody else. To put it another way, I treat red lights and stop signs as if they were yield signs. A fundamental concern of ethics is the effect of our actions on others. My actions harm no one. This moral reasoning may not sway the police officer writing me a ticket, but it would pass the test of Kant's categorical imperative: I think all cyclists could – and should – ride like me.
"I am not anarchic; I heed most traffic laws. I do not ride on the sidewalk (OK, except for the final 25ft between the curb cut and my front door, and then with caution). I do not salmon – ie, ride against traffic."

A tour of Detroit's past glory [Windsor Star]

People called, "Good morning!" A little boy stuck his head out of the secondstory window of a ramshackle house and waved. Cops highfived the public. It was Detroit like you've never seen it.
The Motor City may be on its knees, but on a late summer morning, the sun warm, the sky translucent, there was nothing more fascinating or fun than sailing along the streets in the Tour de Troit.
Magnificent architecture - and burned-out shells. Resplendent parks and vacant, weed-filled lots. We saw it all on the annual bike ride last Saturday.
The 30-mile (my husband and I did that one) and 62-mile rides started in Roosevelt Park at Michigan and Vernor, at the foot of the old Michigan Central Station. I'd never stood in front of the landmark; I'd only seen it from afar. Designed by the same two firms that did Grand Central Station in New York City, now a symbol of Detroit's ruin, it's breathtaking, grander - and more tragic - than I'd even imagined. One after another, people snapped photographs of themselves in front of it.
With the roads closed to cars, we headed west to begin our loop around Southwest Detroit, downtown, midtown and Belle Isle. We passed the handsome and historic Bowen Branch Library, built in 1912 of buff Ohio stone and red vitrified brick (there's a fireplace inside made from tile from a noted local pottery still in business). Right after was Clark Park, the only place in Detroit with a regulation outdoor hockey rink. We pedalled through North Corktown, part of Detroit's oldest neighbourhood, founded in 1834 and named after County Cork, Ireland, were many of its first residents were from.
Remember the love scene in the boiler room in the movie Eight Mile? That was filmed at New Center Stamping, built in the 1930s and still in business as a parts manufacturer. We passed that, too, followed by GM's Detroit Hamtramck Assembly, where the Chevy Volt is made. Then it was on to the massive Packard Plant, designed by Albert Kahn, the foremost American industrial architect at the turn of the last century. It's crumbling and still beautiful.
We rode through Indian Village, where the barons of industry built their elegant mansions between 1895 and the 1920s. On Saturday, the gracious homes were dotted with yard sales. Just before the bridge to Belle Isle is Gabriel Richard Park, a beautiful park at the east end of Detroit's Riverwalk.
We cycled the perimeter of Belle Isle, a treasure of a park with almost 1,000 acres laid out by Frederick Law Olmstead, who designed Central Park in New York City. There's a plan for the state to take it over and refurbish it. On our loop, we passed the Detroit Yacht Club, one of the oldest and largest in the country, and the Dossin Great Lakes Museum, where the bow anchor of the doomed Edmund Fitzgerald is kept.
Heading back east, through Corktown again, we bumped along on one of the old red brick streets.
All along the way, riders and spectators called out, "Good morning!"
The riders waved back at the little boy perched in the window. Many people took pictures and video. Even the police took pictures. One cop held up a sign, "Five miles to go."

People Don't Want to Drive More - But How to Get Them on Bikes? [Treehugger]

Earlier this summer, the Natural Resources Defense Council (NRDC) used a bi-partisan polling team to pose questions about transportation to 800 Americans.
Those polled seemed to agree that our current transportation system needs change. According to NRDC, of those 800 polled:
-59 percent feel the transportation system is “outdated, unreliable and inefficient”
-55 percent prefer to drive less, but 74 percent say they have no choice
-58 percent would like to use public transportation more often, but it is not convenient or available from their home or work
-68 percent support more local investment in improvements to public transportation (including 63 percent of those who do not use transit), with 39 percent supporting it “strongly”

How to Take Your Bike on Transit [Momentum]

Bikes are permitted on Greater Toronto and Hamilton Area GO Trains anytime on weekends and holidays, and on weekdays except during rush hour.
David Rice
Bikes are permitted on Greater Toronto and Hamilton Area GO Trains anytime on weekends and holidays, and on weekdays except during rush hour.
Often, the quickest way to get somewhere in the city requires using more than one form of transportation. If your trip is longer, combining bicycling with other forms of transit is a great option. Here are a few things you can do to make your multi-modal commute a hassle-free experience.
Research Transit Regulations in Your Area
Check out your regional transit website. Not only can you look up bus, train and subway schedules, but you can find cycle specific transit information for your city. For instance, some cities permit bikes to travel on trains at any time, while some prohibit bikes from boarding during peak hours. To find out what regulations you need to be aware of, consult your city’s transit website.
Get a Map
A transit specific map, preferably one that incorporates bike routes as well as transit stations, will take the headache out of trip planning on-the-go. You can usually find maps at transit kiosks, or view the digital version on your regional transit website from your smart phone. Making route choices while you navigate from home, work or school to a transit station and continue on by bike to your end destination is simplified when you have a reliable map in front of you

Review: Surly Disc Trucker - Very well thought out tourer with bags of character

I've long been an admirer of Surly's Long Haul Trucker, so I was well pleased to have a chance to play with the disc equipped version. The downside is that I've got to give it back.
The Trucker is one of those understated 'do-anything' bikes. It's happy hauling rider and luggage on anything from a commute to a round the world tour. The version we tested was the slightly more unusual 26" wheel version, which does make the frame look a little gappy, even in a medium 54cm size. I'll come to that later.
Surly's marketing and branding may be a little too cutesy and hip for some, but the bikes have a good rep for being practical and unfussy. The Trucker amply demonstrates this, with a non-nonsense steel frame in humble 4130.
It's tough, rides well and of course can be repaired by pretty much anyone with a welder. Build quality is excellent with nice tidy welds and the paint job is also very good, with little or no flaking. The graphics are less tough, being decals that have been applied on top of the paint, and the head badge is just glued on. It's not the end of the world but a half scraped off decal does look a bit scruffy...

Letters to the Editor: Ban bicycles during rush hour [Cinci]

In response the letter “Drivers and cyclists must make peace” (Sept. 24). I have a suggestion to at least make things better, as there is no perfect fix. I propose making it law that bicyclists be excluded from riding on streets during the hours of 6:00 a.m. to 8:00 a.m. each weekday morning and from 4:00 to 6:00 p.m. each weekday evening. While I realize this can be a burden to the cyclists, I believe there are more drivers than cyclists and we have a right to be able to get to work on time and to be able to get home in a timely manner after working hard for 8 to 10 hours a day. I know that my road rage knows no bounds after driving up Cornell Road and having to drive 10 miles an hour because cyclists can’t go any faster up hill and there is too much traffic to get around them and I am trying to get home after work.

Letters to the Editor: Driver and cyclists must make peace [Cinci]

Regarding “Bicyclist run over and killed by a Metro bus” (Sept. 12): What do we do about this situation? The law is clear; bicycles are permitted to use pubic streets. What is also clear is that this system is not working. No one should die because of their transportation choice. This situation cannot be allowed to continue.
Vehicle traffic of all types will be increasing in and around the Cincinnati area in the coming years. The time for addressing the problem is now. All sides in this issue have to find a workable solution. The bicycles are not going away and neither are the motorized vehicles.

Leaf Peepers 2012 UPDATE

Hi Folks,
We are 4 weeks away from the 2012 event and I wanted to give you a shout out and invite you out to what may be your last chance at an organized ride in 2012.
We had 25 riders for the first event in 2010 and with their feedback we made significant changes for the following year. The 2011 route got rave reviews - so we didn't change much, only the start from Hocking College to the Square in Nelsonville to get started.

I rode the route on Saturday, 70 miles and I was passed by less than 40 cars - I think that qualifies as a low traffic route despite spending about 30 miles on State highways.
We also have a really nice 35 mile route that will give you some of the best parts of the longer route, but less hills (and miles)

#1) No significant changes on the route - we are starting in the same location but using the bike path to Nelsonville. This takes you right to the light that crosses into the square and then straight onto the route out of Nelsonville.

#2) 3 Rest stops are the same location, these worked really well.

#3) We have added 2 more charities to the support crew, the Lancaster Peloton for Pelotonia and the Tour de Cause. Each of the 3 charities will man a rest stop and you will get to vote on who gave you the best grub.

#4) BIG ADDITION: King of the Mountain and Queen of the Mountain competition. All you have to do is record your ride using a smart phone or GPS recording device and we will help you upload to STRAVA at the end of the ride.
Winner of each division will get their choice of a CCR Jersey or wind vest. At least 2 Men's divisions and 2 Women;s divisions will be awarded.
I rode the route on Saturday and recorded it on my HTC Evo using My Tracks:

#5) The date! Saturday October 20th.
In July my wife was diagnosed with brain cancer and that put Leaf Peepers on the back burner for me. Mitzi's Crusaders that worked the ride are Penny's nieces and family. Since they knew what we were going through, they didn't bug me about a cycling event and just assumed we wouldn't do it.
But we are doing it, and we have enlisted some more support to help with the route.
Mitzi's Crusaders will support the Burr Oak rest stop
Tour de Cause will support the Moxahala rest stop
Lancaster Peloton (Penny's Pals) will support the New Straitesville rest stop

I will keep updating you as we get closer to the event.

Here is the link to the Leaf Peepers page on the CCR website:

Why You Hate Cyclists [Slate]

Partly because of jerks like me. But it’s mostly your own illogical mind.

City cyclist.
Data from nine major North American cities showed that, despite the total number of bike trips tripling between 1977 and 2009, fatalities per 10 million bike trips fell by 65 percent
Photograph by Val Goretsky/Hemera/Thinkstock.
I'm an asshole cyclist. I'm that jerk weaving in and out of traffic, going the wrong way down a one-way street, and making a left on red. I'm truly a menace on the road.

But it’s not because I’m on a bike—I'm an asshole on the road no matter what. I’m also a stereotypical Jersey driver, someone who treats speed limits as speed minimums and curses those who disagree. And I'm just as bad as a pedestrian, another jaywalking smartphone zombie oblivious to the world beyond my glowing screen. If I’m moving, I’m an accident waiting to happen.
Biking is my primary means of transportation, so when someone defames cyclists, I feel particularly bad. The fact is, unlike me, most bicyclists are courteous, safe, law-abiding citizens who are quite willing and able to share the road. The Bicycle Coalition of Greater Philadelphia studied rider habits on some of Philly’s busier streets, using some rough metrics to measure the assholishness of bikers: counting the number of times they rode on sidewalks or went the wrong way on one-way streets. The citywide averages in 2010 were 13 percent for sidewalks and 1 percent for one-way streets at 12 locations where cyclists were observed, decreasing from 24 percent and 3 percent in 2006. There is no reason to believe that Philly has particularly respectful bicyclists—we’re not a city known for respectfulness, and our disdain for traffic laws is nationally renowned. Perhaps the simplest answer is also the right one: Cyclists are getting less aggressive.
recent study by researchers at Rutgers and Virginia Tech supports that hypothesis. Data from nine major North American cities showed that, despite the total number of bike trips tripling between 1977 and 2009, fatalities per 10 million bike trips fell by 65 percent. While a number of factors contribute to lower accident rates, including increased helmet usage and more bike lanes, less aggressive bicyclists probably helped, too.
