Free the brake and your mind will follow

No break on no brakes: Cyclists object to ticketing over fixed-gear bikes -- bpurvis@journalsentinel.com (Milwaukee)

Cory Gassmann is selling fixed-gear bikes at his east side shop about as fast as he can stock them.

Matthew Hewitt, manager at Cory The Bike Fixer shop, 2410 N. Murray Ave., shows how he is able to use pressure to stop his "fixie," a fixed-gear bicycle that has neither hand nor coaster brakes.

In recent years, the bikes have gone from the favored setup for a handful of hard-core bike messengers looking for a low-maintenance ride to a bona fide fad among hipsters and cycling minimalists.

There is one group, however, the bare-bones bikes aren't so popular with: police, who say many of the bikes violate laws requiring a bicycle to have a brake.

Fixed-gear bikes, or fixies, are single-speed bikes without a freewheel. As the bike moves forward, the rider is forced to pedal. The cost varies widely, from bikes built from scrap parts to track racing bikes costing several thousands of dollars.

Fixies can be outfitted with a hand brake, but many are not. For those bikes, the riders slows down by pressing against the forward motion of their pedals.

Nicole LaBrie, a 23-year-old bike messenger, found out the hard way this summer that police don't consider that braking when she got a $64.80 ticket.

She was stopped for going the wrong way on a one-way street, for which she also was fined.

The officer "said, 'You don't have brakes.' I said, 'I do, but you can't see them. I can stop,' " said LaBrie, who plans to challenge the brake ticket in court.

The issue came to light in a recent case in bicycle-crazed Portland, Ore., in which a county judge ruled that 24-year-old bike messenger Ayla Holland violated a state law similar to Wisconsin's; she is appealing the ruling. The case has online message boards abuzz.

In Milwaukee, LaBrie is one of two people ticketed over the ordinance this year. Three were ticketed last year.

Milwaukee's ordinance was adopted from a state statute that reads in part: "No person may operate a bicycle . . . upon a highway, bicycle lane, or bicycle way unless it is equipped with a brake in good working condition, adequate to control the movement of and to stop the bicycle."

A ticket for riding without a traditional brake is reasonable based on how the law reads, but it remains to be seen whether a judge would agree, said Richard Withers of the city's Legislative Reference Bureau.

"It just depends on whether a judge thinks a fixed gear that will stop you is not a brake," Withers said. "In effect, it's a better brake than some of them . . . It's just a question of whether you define the brake broadly to one of those contraptions that pinches the tire."

Wayne Wallner, who owns Breakaway Bicycle Courier, where LaBrie works, said he carries a copy of the ordinance to help his argument.

"We have a brake. It's a chain brake. In fact, it's the simplest of all brakes, and the strongest," Wallner said. "I can show you that I can control the movement of my bicycle, so why give me a ticket?"

Wallner said that if police understand the mechanism, they could be convinced it is a legitimate and reliable braking system.

"We have even more control of our bikes. Our hands are always on our handlebars. Our feet are always strapped into our pedals. There are no gears to shift, no cables to snap," Wallner said. "It's like any other brake except it's done with your legs instead of your hands."

Police say they do understand how it works, and it's against the law.

"It's not a brake," said Mark Buetow, a community liaison officer for Milwaukee's District 1. "If the bike is rolling forward, the pedals are going forward. There is no way to independently stop the bike independent of the rotation of the rear wheel."

Buetow said affixing a hand brake would keep fixie riders from being ticketed.

Some bike activists wonder whether fixies are a legitimate traffic issue.

"There aren't a lot of bicycle crashes in Milwaukee to begin with, and I can't remember the last time I heard about a crash that happened because someone was riding a fixie and couldn't stop," said Jack Hirt, project coordinator for the Bicycle Federation of Wisconsin.

As the debate plays out, fixies continue to fly out of Gassmann's shop, Cory The Bike Fixer, 2410 N. Murray Ave., where he recommends an auxiliary front brake but falls on the side of the fixie riders' defense.

"We just can't keep them in stock to save our lives. There are all kinds of kids riding them," he said.
According to this logic, we need to outlaw skateboards, red wagons, tricycles, pogo sticks, and bowling balls.

In related factoids, I knew that Canadians allowed bicyclists on interstates but did not know that several American states did as well:
Allowed on all interstates: Idaho, North Dakota, South Dakota, and Wyoming

Allowed on certain sections of interstate system: New Jersey (Permits granted for particular use and location), North Carolina (DOT may approve opening certain section), Pennsylvania (DOT may approve opening certain section)

Allowed on interstates where no alternative route exists (usually means access is prohibited in urban areas): Alaska, Arizona, California, Colorado, Montana, Nevada, New Mexico, Oklahoma, Oregon, Texas, Utah, and Washington

Access not expressly prohibited: District of Columbia and Missouri

In all other states, bicyclists are not allowed to ride on interstates. However, even in these states, there are exceptions to this rule where bicyclists are permitted to use a particular bridge that is part of the interstate system (e.g. I-66 in Virginia, I-70 in Kansas).
I have snuck across a few freeway bridges where otherwise it meant a huge detour. Sometimes you got to do what you gotta do.

At It Again

The commenters at HuffPo have universally dumped on the latest oil economics "analysis" by Raymond Learsy. This time Learsy has gone ga-ga over the latest deep-water GOM find and has taken to calling those not imbued his insider commodities trader knowledge as "peak oil pranksters". Learsy has posted regularly on oil and it appears that readers have started to catch on to his strategy of trying to create a populist wedge issue by placing himself against "Big Oil" and the corporatist's manipulation of prices. Take a look and you will find that no one buys his attitude and instead considers him a projectionist shill. One of the only commenters to agree with Learsy amusingly said this:
There is no shortage of oil. Professor of Physics at Cornell University, Thomas God, has proven that natural gas and oil come from deep reservoirs in the earth and are the result of material out of which the earth condensed. Those who believe gas and oil are biogenic hydrocarbons are dupes of the oil industry.

Note the Freudian slip, Thomas God. Say no more, we all realize that God knows all.

Avedon at The Sideshow finds a brilliant quote that pure capitalists such as Learsy deliberately eliminate from their worldview:
A letter in Wednesday's International Herald Tribune:

"President George W. Bush has rightly pointed out that America is addicted to oil, but he fails to note the predictable consequences.

Addicts break into houses, steal stuff and shoot people. America is breaking into countries, stealing stuff and shooting people. Why is anyone surprised that those homeowners object to our addictive behavior? - Sheila Stoll Morcote, Switzerland
"

Stock Cars and Stock Puppet

Look to the right for an endangered species. The hairy NASCAR freak. Fortunately, our continual world-wide oil depletion has likely stopped his de-evolution in its tracks. Instead, human selection will proceed in accordance with the highly advanced hairless prototype road-bikers who would gladly trade in their Lady Bics for a skin-tight model.

I ran across the Neanderthal pic in the process of tracking down a reference by the coke-addled stock-market analyst Larry Kudlow, who said that with the latest deep-water finding in the Gulf, we now can count on "kajillions" of oil in reserve. This audio exaggeration happened on the Spew Spewitt radio show, who alas did not have the particular transcript. But he did have a few other transcripts up, which happened to have got impregnated with some type of latent Y2K virus or more likely follow the new Pat Robertson "special end-times calendar".

Do these right-wing nutters possess any intelligence at all? We just finished the State Fair here and the visiting Spewitt unwittingly got mocked by his sponsor, accurately portraying him as a 'minionist-on-stick.

Looks painful. But hey, definitely worth the ritual sacrifice for the discovery of a hard-to-reach, expensive, and unreliable source of fossil fuel.

And that constitutes the once-a-year right-wing nutter mention of our apparently solved oil predicament -- summed up by a single word: kajillions.

The great Digby elaborates on the Spew's unctuousness.

Fiber: Good for You

I just received my ebay-ordered carbon-fiber road bike today. I probably deserve whatever bad happens, buying a supposedly new bike sight unseen and all, but I suppose I needn't worry about keeping it pristine now as I find a bunch of nicks and blemishes covering the frame. Apparently it tips the scales at 16.5 pounds -- about the minimum attainable without having to spend a few more grand -- but I don't really think I will notice the weight savings much. Taking the bike out for a test ride, I essentially dodged a bullet and concluded that I didn't get taken in completely by an ebay huckster.

Monitoring the way ebay bids pan out on used bikes, the average follows the basic pattern of depreciation of 35% from the manufacturer's suggested retail price on the first year of use and 10% every year thereafter. Overall, the auction participants follow the time-honored traits -- bidders get over-excited and the sellers act like they deserve every penny coming their way.

Best deal on an amazing piece of engineering: the $25 dollar BikeNashbar clipless pedals.


I also received a new pair of XC skate bindings in the mail. One of my currently installed bindings gave out last winter on the clap mechanism. From the looks of it, the makers of the binding, Salomon, actually reinforced the mechanism that broke on me, providing me hope that at least a few companies practice process improvement.

Hot Gas

We should monitor this story as it winds its way into common wisdom or an urban legend.

"Hot Gas" Shorting Drivers $2.3 Billion And Who Cares?

The issue boils down to whether underground-stored gasoline cools off or retains its heat from transport. If the latter, the gasoline's volume expansion upon increasing temperatures means that consumers can get skimmed on the order of few cents to the gallon.

And speaking of hot air, don't you agree that this introspective article reads a bit on the precious side?
I came to the realization that no combination of alternative energy strategies was the messiah I had long thought. This was an emotional period in my life. ...
Please, put me out of my virtual misery before treacle like that emanates from this here anonymous blog.


Word of the day:
alternative energy sources /n. phr./ 1. New locations to drill for gas and oil. 2. Coal mines.

The Great American Oiligarchy

An old-timer journalist calls it:

Stephen Fleischman
The war in Iraq is the best example of an oligarchy at work-produced and managed to make money and to secure the remaining reserves of oil in the world. As they say, the world's oil has "peaked". It's all down hill from here, so we better grab it before somebody else does. To do this, we're got to keep a perpetual war spinning in the best oil-producing areas, the Middle East and the Caspian region. (We'd do it in Venezuela if we could.) With Iraq as a pivotal base, the oligarchy is planning to stay there into the foreseeable future. Any talk about drawing down troops is just that, talk-a tease offered for the 2006 mid-term elections. Using Iraq as a military base also explains the moves on former Soviet states, Kazakhstan, Uzbekistan, Azerbaijan and others in the Russian orbit-targets of the giant oil conglomerates.

Oligarchies operate in secret. ....

Production over discoveries

An oil depletion trend line that should get more pub plots the monotonically increasing ratio of production over estimated discoveries as a function of time. I show this value for each past decade in the following table:
DecadeProduction/Discoveries
1940's0.14
1950's0.2
1960's0.29
1970's0.62
1980's1.07
1990's2.0

I find it portentous that the numbers look like they increase at a roughly exponential rate, but we know that can't keep going forever. At some point it needs to show an inflection point and start to level off and then creep back toward 1 -- which means that we use as much as we find. And although the current decade has not contributed its data point yet, the accumulated numbers have not yet budged from the previous decade. When we look back at the inflected curve, it will point out in hindsight the physical rationale behind what we see in purely economic terms -- i.e. plotting the production peak alone only tells half the story.
