Bicycle Helmet Use Is A Must!


     A word to the wise:  NEVER even put a leg over the top tube of a bicycle frame without wearing a helmet!  If you accidentally snag your foot on the top bar or put your foot down on a loose rock and lose your footing -- or your balance -- you’ll come crashing down HARD:  right on your unprotected skull!  It's a very hard way to learn that the cost of a good ("ANSI"-, or "SNELL"-approved) bicycle helmet is much less than the cost of the insurance deductable for a visit to a hospital emergency room; along with diagnostic x-rays and follow-up treatment, etc.  And that's not evening considering the potential avoidance of pain and suffering of a cracked skull!

     By the way, generally what determines the severity of the injury to your skull is mostly a factor of the height -- and gravitational acceleration -- from which your head falls to the ground.  It's not necessarily a factor of the "speed" at which your going forward on a bicycle:  The speed your travelling forward mostly determines the number of times your head hits and bounces off and re-impacts the ground, or other objects: such as a curb, tree, car bumper/windshield, another bicycle rider, and/or pedestrian, etc.

      This does not necessarily mean that you might not still suffer a concussion while wearing a bicycle helmet, as your brain still can "slosh around" and impact the inside your skull in any sudden abrupt-halt accident.  BUT, the helmet most definitely can soften the blow and lessen the possible severity of such an accident.  Of course, there is always the possibility of neck injury with (or without) a helmet on. Regardless, you're still much better off wearing a helmet in all cases at all times when you’re riding. That holds true even if your "just going around the block," as most bicycling accidents -- at least for the less-experienced, occasional, or moderate-mileage bicycle rider -- occurs on short rides, closer to home.

Head Injury Can Blight Survival Up to 13 Years Later

Concussions: An Overlooked Epidemic - (51 min. - audio) - (Sept. 12, 2011 - The Diane Rehm Show/NPR) - The U.S. Centers for Disease Control estimates between two and four million people suffer from concussions every year. Brain injuries are vastly under-reported and diagnosis is difficult because the damage is invisible to brain scanners. Concussion victims often fail to link headaches, fatigue and memory loss to what seems like a minor injury. While most concussions are sports-related, a sizable number affect victims of car accidents or falls. The science and symptoms of brain injuries and why they’ve become an overlooked epidemic.  -

Helmet Crash Tests: Don't Hit The Road Without One - June 13, 2013 — Bicycle helmets certified to Australia's national standard significantly reduce the causes of head, skull and brain injury -- linear and angular head accelerations, and the impact force of a crash -- a new laboratory study has found.

Crashing without a helmet exposes the head to accelerations and forces -- or loads -- up to 9.5 times greater than with a helmet and so greatly increases the risk of head, skull and brain injury, according to a detailed biomechanical study published in the journal Traffic Injury Prevention.  -

Bicycling Beats Brown Haze Daze


[Here's an interesting quote from the 'Paceline' column

on page 32 of the April, 1990, issue of "Bicycling" magazine.

It concerns the hazards to your lungs/heart and health in relation to bicycling,

urban air pollution and cigarette smoke.]:


   "If you've ever wondered how dangerous it is to bicycle in a polluted urban area,

take a deep breath and relax.

  A recent study found that riding a bicycle in New York City

is far less damaging to the lungs than smoking cigarettes

or even being in a room full of smokers.

  In fact, the amount of carbon monoxide in the blood of midtown bicycle messengers

actually declined during the course of a day,

prompting speculation that hard breathing may expel pollutants from the lungs."

Medical Sleuthing Linked Muscle, Kidney Problems to Kava Tea - ScienceDaily (Apr. 27, 2011) — When a 34-year-old bicyclist was found collapsed on a roadside and rushed to the University of Rochester Medical Center emergency room on the verge of kidney failure and muscle breakdown, doctors were surprised to discover that a trendy tea derived from the kava plant was the cause of his ills.

The URMC team reported the case study, believed to be the first of its kind in the scientific literature, in the American Journal of Emergency Medicine. They described it as a cautionary tale, emphasizing the importance of taking a thorough medical history, including the use of any and all herbal remedies and pharmaceuticals.  -

The Bikenomics Series - (2011) - Bicycle transportation is good for a lot of things—it’s healthy, it’s green, it’s quiet, it’s fun, it builds community. It also makes financial sense, and the magnitude of bicycling’s economic impact gets far less attention than it deserves. In the Bikenomics series, Elly Blue explores the scope of that impact, from personal finance to local economies to the big picture of the national budget. In the grassroots and on a policy level, the bicycle is emerging as an effective engine of economic recovery.  -

Cardboard Bike Helmet Better than Plastic  - (June 7, 2011 - by Charlie Sorrel - Wired) Kranium is a bike helmet that is made from the same cardboard used for the boxes you find at the supermarket. This material, along with some clever construction, turns out to be a lot better at absorbing impact than the more usual polystyrene-filled lids.

Anirudha Surabhi’s design absorbs four times more impact energy that the polystyrene equivalent, and — unlike regular helmets which break on impactit survives longer. One Kranium was smashed five times in a row and still passed the British Standard (EN 1078) test.

What about rains and sweat? No problem. Surabhi’s helmets mix the cardboard with a “waterproof acrylic compound” which makes them just as rain-resistant as the helmet you have now.

The Kranium is better than regular helmets in another way too. Because they are easy to build to order by scanning the buyer’s head and cutting the cardboard to order, it fits perfectly. This means that it will stay in place if you crash, offering much better protection.

Surabhi’s design has already been licensed by some major manufacturers, so this is one student project that may make it into stores.  -

Full-Sized Electric Scooter Legal in Bike Lanes - (Sept. 28, 2011 - by Charlie Sorrel - Wired) - What would you say if I told you that the scooter you see above will soon be shooting around your town or city, nipping in and out of bike lanes, piloted by untrained, unlicensed drivers? If it makes you angry, prepare to get angrier still, because what I just told you is the truth.

The scooter, called the FlyKly, is a rechargeable electric motorbike with vestigial pedals. Because it can reach just 20mph and has a motor of less than 750W, it qualifies under Federal electric bicycle law as a pushbike. 20mph (or 32km/h) isn’t fast enough to ride in traffic, but is fast enough to be a danger to cyclists.  -

Increased Use of Bikes for Commuting Offers Economic, Health Benefits - ScienceDaily (Nov. 2, 2011) — Cutting out short auto trips and replacing them with mass transit and active transport would yield major health benefits, according to a study just published in the scientific journal Environmental Health Perspectives.

The biggest health benefit was due to replacing half of the short trips with bicycle trips during the warmest six months of the year, saving about $3.8 billion per year from avoided mortality and reduced health care costs for conditions like obesity and heart disease.

The report calculated that these measures would save an estimated $7 billion, including 1,100 lives each year from improved air quality and increased physical fitness.

Moving five-mile round trips from cars to bikes is a win-win situation that is often ignored in discussions of transportation alternatives, says Jonathan Patz, director of the Global Health Institute at the University of Wisconsin-Madison. "We talk about the cost of changing energy systems, the cost of alternative fuels, but we seldom talk about this kind of benefit," he says.  -

Biker's Warning! EPO Hits Blood Vessels to Raise Blood Pressure in the Brain - ScienceDaily (Dec. 9, 2011) — Erythropoietin or EPO might be considered a "performance enhancing" substance for athletes, but new research published online in The FASEB Journal shows that these enhancements come at a high cost -- increased risk of vascular problems in the brain. According to the study, short- or long-term use of EPO raises blood pressure by constricting arteries, which reduces the flow of blood to the brain. This finding also contradicts earlier evidence suggesting that EPO may be a viable early treatment for stroke victims.  -

I'm a frequent cyclist who uses my bicycle to go places and do things. I ride to clients, to the grocery store, to the bank - wherever. And I really hate what Trailnet & Company are doing, because it makes me less welcome on the very roads I'm using today. Across the region, they push bike lanes, which you might as well call bike ghettos. And they advocate sharrows, which are almost always put right at the edge of traffic lanes, where it is dangerous to ride.

State law already provides me with a very useful network of bike lanes: The lanes in which the rest of you drive your cars also serve me quite well. I use them safely and comfortably, and with the exception of an occasional hostile or inattentive motorist, without incident. Pushing me onto bike lanes, a "separate and unequal" place, is a big step in the wrong direction.

It's Not About the Lab Rats  - (February 2012 - by Bill Gifford - Outside Magazine) - If Lance Armstrong went to jail and Livestrong went away, that would be a huge setback in our war against cancer, right? Not exactly, because the ­famous nonprofit donates almost ­nothing to scientific research. BILL GIFFORD looks at where the money goes and finds a mix of fine ideas, millions of dollars aimed at “awareness,” and a few very blurry lines.

IN ONE CASE, ARMSTRONG himself stood to profit from the sale of a major Livestrong asset: its name. Most people are unaware that there are two Livestrong websites. is the site for the nonprofit Lance Armstrong Foundation, while is a somewhat similar-looking page that features the same Livestrong logo and design but is actually a for-profit content farm owned by Demand Media. 

In 2008, the foundation licensed the Livestrong brand name to Demand, the online media company behind eHow and, among other properties. was positioned as a “health, fitness, and wellness community,” offering an online calorie counter, exercise and yoga videos, and articles about such topics as “What Are the Signs and Symptoms of Rejecting Belly Button Rings?”

As compensation for the use of its name, the foundation received about 183,000 shares of stock, which it sold for $3.1 million when the company went public in January 2011. Armstrong also received 156,000 shares of his own as part of a spokesperson agreement. (His agents, Bill Stapleton and Bart Knaggs, also received shares.) After the deal was criticized in the media, Armstrong donated his initial sale proceeds—roughly $1.2 million—to the foundation and said he planned to donate the rest, too.


Adds Ulman: “They guaranteed us certain levels of traffic. They said, ‘We will build a site, and we will ultimately send people to the foundation.’ ” But traffic to the for-profit Demand Media site has surged, in part thanks to Lance’s promotional work, while the foundation’s traffic has remained essentially flat. And it was the foundation that paid to defend their joint trademark....

It’s definitely questionable,” says Mark Zimbelman, the Brigham Young University professor behind Fraudbytes. “Imagine if the American Red Cross sold its name to, and you can go there and buy vitamins. You think you’re donating or helping the American Red Cross, but you’re really not. It’s unheard of.”  -

Seeking Revenge In 'Underworld Of Vanished Bikes' - (17 min. - audio) - (Feb. 6, 2012 - Talk of the Nation/NPR) - In 2006, thieves stole writer Patrick Symmes' bike in broad daylight on a crowded, New York City street. This inspired Symmes to set out to catch a bike thief — any bike thief.

He tells the tale of this revenge-fueled, cross-country journey in the Outside magazine piece "Who Pinched My Ride?" The story is filled with GPS trackers, police stake-outs and undercover stings.

By some estimates, more than one million bike thefts go unreported annually. The annual value of stolen bikes is as much as $350 million, according to the FBI and the National Bike Registry. Still, some police departments are not following up on the crimes.

Symmes talks with NPR's Neal Conan about the world of organized bike crime and the measures bike owners will take to retrieve their stolen property.  -

Bike Sharing Takes Over America - (Oct. 25, 2012 - by Alexander George - Wired) - Bike share programs are spreading across the United States like carbon-reducing wildfire. Since the launch of the first modern U.S. bike-share system in 2008 (yes, the system has been around for decades, but 2008 was the first theft-proof and functioning system), 29 have popped up. In 2012 alone, eight new cities have set up bike share programs with more scheduled to begin in cities like New York, Los Angeles, and Fort Worth.

Capital Bikeshare in Washington, D.C. is the model share program of the moment. Starting in 2010 with 1,100 bikes and 18,000 members, the program now has over 1,670 bikes and 175 pick-up and drop-off stations, making it the largest sharing consortium in the country.

The major reason that bike shares actually work is the technology that keeps a share organization’s inventory in check. Free and coin-operated programs usually succumbed to theft, but new innovations in inexpensive bicycle tracking technology keep the fleet intact.  -

Less Than 25 Percent Of Americans Walk For More Than Ten Minutes Continuously In A Typical Week - ScienceDaily (Nov. 30, 2012) — Many people in the U.S. do not walk, bike or engage in other forms of active transportation, missing an important opportunity to improve their cardiovascular health, concludes a new study in the American Journal of Preventive Medicine.

Active transportation refers to any form of human-powered transportation, most commonly walking and cycling, but also using a wheelchair, in-line skating or skateboarding. The study's researchers suggest active transportation is "an untapped reservoir of opportunity for physical activity for many U.S. adults."

"We knew that many studies have demonstrated that physical activity can help prevent a variety of conditions like high blood pressure, obesity, diabetes and serum lipid abnormalities -- all risk factors for developing cardiovascular disease," said lead study author Gregg Furie, M.D. of the Yale School of Medicine, who specializes in adult primary care medicine. However, the majority of previous studies done on physical activity primarily focused on its use in recreational activity or leisure time activity, he noted.


The U.S. has one of the lowest rates of active transportation in the world, said James F. Sallis, Ph.D., chief of the division of behavioral medicine at the University of California, San Diego."This is not an accident. U.S. transportation policies and funding prioritize travel by car, unwittingly discouraging active travel," said Sallis, who is also director of active living research at UCSD. "This situation is made worse by land use and zoning policies that separate residential and commercial zones to the extent that it is not feasible to walk for daily needs. These new findings point out how transportation policy is health policy."

He called the study "powerful evidence from a large national sample that active transportation is just as beneficial to health as leisure-time physical activity. Not surprisingly, the findings highlight that transportation policies that essentially ignore walking and cycling appear to be contributing to the major chronic diseases that account for 80 percent of healthcare costs."

There's a need for better understanding of the overall benefits of active transportation, Furie said. "This information adds to the weight of evidence that suggests more work is necessary to develop environmental policies that make it safer, easier, and more desirable for people to walk and bike for transportation."  -

Ferguson (Missouri) Street Signs Mark Safety Advance For Bicyclists - (Dec. 3, 2012 - by Paul Hampel - Political Fix/St. Louis Post-Dispatch) - Martin Pion resisted getting pushed to the curb, and now bicyclists have a safer ride through Ferguson.

Prompted by Pion's pro-bike activism, Ferguson recently installed street signs that reflect a change — perhaps the first like it in the state — to a traffic ordinance regulating lane usage.

Two custom-made signs at each end of Ferguson-controlled Florissant Road, a major north-south route, indicate that bicycles now may use the full lane and that other vehicles may change lanes to pass.

The signs follow the repeal in June of the city's so-called “Far to the Right” ordinance that required cyclists to “ride as near to the right side of the roadway as safe.”

Pion spearheaded the change after one of the city's police officers pulled him over for violating the ordinance. Pion had been riding his bike in the center of the right lane on Florissant Road.

“I was controlling the curb lane near my home while bicycling to Ferguson's downtown,” Pion, 76, of Ferguson, said on Monday.

The English-born Pion is a longtime champion of bicycle commuting who has taught classes on cycling safety. - [NOTE: Martin Pion is a registered Effective Cycling Instructor.  --Bike Bob]

He prefers riding in the center of the curb lane, asserting that, contrary to the provisions of the old ordinance, cycling becomes more dangerous the farther one rides to the right.

The far right side typically is the worst part to travel on. You have drain grates, debris that accumulates and gets swept infrequently, there's also a joint there and you are less visible to motorists."

He added, By riding far to the right, you are more likely to get crowded by large vehicles trying to pass you. By controlling your lane, you are signaling to following motorists that they should change lanes to pass you because they won't be able to do it safely within the lane.

Pion said he regards "Far to the Right" laws as “discriminatory to bicyclists.” He said his research has indicated that Ferguson is the first entity in the state to repeal such an ordinance.

"Hopefully, other cities will follow suit," he said.

Partly because of Ferguson's strong support of the bicycling movement, statewide health officials have pointed to the city as a leader among area communities in efforts to promote healthy living.

Spidey-Sense Suit Tingles When Someone Gets Too Close - (February 22, 2013 - by Hal Hodson - NewScientist) - The suit, called SpiderSense and built by Victor Mateevitsi of the University of Illinois in Chicago has small robotic arms packaged in modules with microphones that send out and pick up ultrasonic reflections from objects. When the ultrasound detects someone moving closer to the microphone, the arms respond by exerting a growing pressure on the body. Seven of these modules are distributed across the suit to give the wearer as near to 360 degree ultrasound coverage as possible.

"When someone is punching Spider-Man, he feels the sensation and can avoid it. Our suit is the same concept," says Mateevitsi. SpiderSense could help blind people to find their way more easily, he says.

Mateevitsi tested the suit out on students, getting them to stand outside on campus, blindfolded, and "feel" for approaching attackers. Each wearer had ninja cardboard throwing stars to use whenever they sensed someone approaching them. "Ninety five per cent of the time they were able to sense someone approaching and throw the star at them," says Mateevitsi.

"I'm very excited about this," says Gershon Dublon of the Massachusetts Institute of Technology, who also works on augmenting parts of the human body. Mateevitsi's work is a step on the road to giving humans truly integrated extrasensory perception, says Dublon.

Mateevitsi wants to use the suit, or just a few sensors on the arms and back, to boost cyclists' awareness of other traffic on the road. SpiderSense is due to be presented at the Augmented Human conference in Stuttgart, Germany, in March. The team now plans to add more sensors to the suit to increase its resolution.  -

According to a 2011 study, some 320,000 severely brain-injured servicemen and women have returned from Iraq and Afghanistan, most of the trauma the result of concussive IED blasts.  ….


The Centers for Disease Control and Preven­tion estimates that between 1.6 million and 3.8 million sports-related concussions ­occur in the U.S. each year. A report funded by the City of New York found that brain injuries are responsible for 74 percent of bicycling deaths. Nationwide, according to the ­American Asso­ciation of Neurological Surgeons, ­roughly 600 bicyclists die annually as a result of head injuries, and in 2009, some 85,000 concus­sed bicyclists ended up in emergency rooms.


Axons are the fibers that serve as your brain’s messengers, and neurons are the command centers tasked with the functions that make up who you are. One neuron might be involved with short-term memory, another with balance, another with impulse control. Simple, except that there are an estimated 100 billion neurons in the human brain.


One thing neurologists are certain of is that even mild concussions are more serious than they once thought. Axons can be stretched hard only once, or lightly many times, before rupturing. And when they do, brown balls of protein—scars left from the brain’s attempt to heal itself—form in the pathways, shutting down communication. The resulting chronic traumatic encephalopathy has been linked to everything from depression and dementia pugilistica (punch-drunk syndrome) to diseases like Alzheimer’s and Parkinson’s.  -

Biking Across America On A Diet Of Fast Food - (Dec 8, 2015 - by Tom Vanderbilt - Outside Magazine) - Fueled by Pop-Tarts and Little Debbies, 52-year-old software engineer Kurt Searvogel is out to break the record for the greatest distance pedaled in a year. What motivates a man to ride more than 200 miles a dayevery day, rain or shine, hot or cold, sunrise to sunset?


Surely all this exertion, fueled by the cornucopia of the American drive-through lifestyle, can’t be good for you. I put the question to Michael Joyner, a physician at the Mayo Clinic who specializes in exercise physiology, particularly “human limits” (the title of his website). Joyner doesn’t have a problem with Searvogel’s diet: a calorie is a calorie, he believes (at least in the short term), and he’s always wanted to do a study with endurance athletes to prove it. What’s more, he points out, many people have persisted at these levels of exertion all day, every day, throughout history: it’s called work.

But as long as a rider is not constantly pushing the red zone in terms of heart rate, Joyner says the biggest risks are from injury, overuse, and illnesses that can be worsened by intense physical effort. What these cyclists are doing “sounds incredible, and it is incredible,” says Joyner. “But if you do the math behind it—the fuel, the caloric consumption—and make a few assumptions about the individual’s maximum oxygen consumption, the fact is that humans can work at about 40 percent of their maximum all day. As long as they don’t get dehydrated, they’re good to go.” 

Which is not to say the road has been clear of obstacles. Searvogel has been hit by cars twice, both times at the intersection of a bike path and a road. -
