How do I choose a bicycle to purchase?




Jinx U


I want to buy a bike to ride to work, but I have no idea how to go about finding a good one. (Heck, I thought bikes cost $150...they do, at Target, but I'm told those aren't the best bikes.)

What makes a bike good? How do I pick one out for myself? What should I expect to pay?

I figure I don't need a mountain bike since I'll be riding on asphalt bike paths, and obviously, I'll want a woman's model, but other than that, I'm clueless.

And what about helmets, ect? I know I need a helmet, but how do I pick one out and what makes a good one?

Any advice, tips, or suggestions you can give me will be appreciated! Thanks!



Answer
Go with Consumer Reports on the bike or helmet. They are not biased by brand name or company image.

can you paraphrase this texts ?

3.Of the more than 1000 bicycling deaths each year, three-fourths are caused by head injuries. Half of those killed are school-age children. One study concluded that wearing a bike helmet can reduce the risk of head injury by 85 percent. In an accident, a bike helmet absorbs the shock and cushions the head. From "Bike Helmets: Unused Lifesavers," Consumer Reports (May 1990): 348.
4.Matisse is the best painter ever at putting the viewer at the scene. He's the most realistic of all modern artists, if you admit the feel of the breeze as necessary to a landscape and the smell of oranges as essential to a still life. "The Casbah Gate" depicts the well-known gateway Bab el Aassa, which pierces the southern wall of the city near the sultan's palace. With scrubby coats of ivory, aqua, blue, and rose delicately fenced by the liveliest gray outline in art history, Matisse gets the essence of a Tangier afternoon, including the subtle presence of the bowaab, the sentry who sits and surveys those who pass through the gate. From Peter Plagens, "Bright Lights." Newsweek (26 March 1990): 50.
5.While the Sears Tower is arguably the greatest achievement in skyscraper engineering so far, it's unlikely that architects and engineers have abandoned the quest for the world's tallest building. The question is: Just how high can a building go? Structural engineer William LeMessurier has designed a skyscraper nearly one-half mile high, twice as tall as the Sears Tower. And architect Robert Sobel claims that existing technology could produce a 500-story building. From Ron Bachman, "Reaching for the Sky." Dial (May 1990): 15.

3. Head injuries account for 75 percent of all bicycling deaths and half of the 1000 fatalities are school-age children. One study concluded that a bike helmet can cushion the head and absorb shock, thereby reducing head injuries by 85 percent. From "Bike Helmets: Unused Lifesavers," Consumer Reports (May 1990): 348.

4. Matisse was an expressive painter, capable of effectively placing the viewer in the midst of his scenes. As a realistic modern artist, Matisse seemed to incorporate the feel of the breeze and the smell of oranges into his still life. "The Casbah Gate" depicts the well-known southern gateway Bab el Aassa, near the sultan's palace. Matisse captured the essence of an afternoon in Tangier by his subtle use of color set against perhaps liveliest gray outline in art history. Even the bowaab, or sentry, surveys all who pass through the gate and all who view the painting. From Peter Plagens, "Bright Lights." Newsweek (26 March 1990): 50.

5. When the Sears Tower was completed it was considered the greatest example of skyscraper engineering. Architects and engineers still dream of designing the world's tallest building, but just how high can a building go? Structural engineer William LeMessurier has already designed a skyscraper nearly one-half mile high, or twice as tall as the Sears Tower. Another architect, Robert Sobel, claims that existing technology could produce a 500-story building. From Ron Bachman, "Reaching for the Sky." Dial (May 1990): 15.

1. "The Antarctic is the vast source of cold on our planet, just as the sun is the source of our heat, and it exerts tremendous control on our climate," [Jacques] Cousteau told the camera. "The cold ocean water around Antarctica flows north to mix with warmer water from the tropics, and its upwellings help to cool both the surface water and our atmosphere. Yet the fragility of this regulating system is now threatened by human activity." From "Captain Cousteau," Audubon (May 1990):17.

The question is : Just how high can a building go? Structural engineer William LeMessurier has designed a skyscraper nearly one-half mile high, twice as tall as the Sears Tower.

Answer
1. The Antarctic is very cold on our planet. The sun has a lot of control with our climate. The water around Antarctica goes north and mixes with warmer water, and it helps cool our surface water and atmosphere. This system is fragile.

2. Three-fourths of bicycle deaths are caused by head injuries. Half were school kids. Wearing a helmet can reduce injury to the head. A helmet cushions the head in an accident.

3. The Sears tower is possibly the best achievement in skyscraper engineering. A structural engineer has made a skyscraper about one and a half mile tall. That's twice as tall as the sears tower.

Honestly? Are the $70-$120 (Louis Garneau,Giro,etc) helments any safer then a $20 dollar Bell or Shwiinn???




Yalow


Bell of Schwinn from Target or Walmart??

I'm sure there is a difference in aerodynamics but is there really that much of a difference in safety?

Thanks
Excuse the massive amount of typos there...thanks for you input.
And if there is a difference....How so?



Answer
Taken from a FAQ page from www.helmets.org:

Is a cheap helmet as safe as an expensive one?

Maybe. Probably. Almost. Maybe safer. Apart from the models Consumer Reports rates, we don't have lab test data on the helmets out there. All of them manufactured after 1999 must meet the CPSC standard by law to be sold in the US. If money buys you a better fit, with more stability on your head in a hard crash, then the more expensive helmet is worth it. If it just buys you a spiffy-looking, squared-off, poorly-rounded exterior with points to snag, definitely not.

What about helmet standards?

Helmet standards test for things you can't judge in a store: impact performance and strap strength. The US Consumer Product Safety Commission's bike helmet standard is law now for every helmet made after 1999. So CPSC is the benchmark standard. ASTM and Snell B-90 are similar to it, and Snell B-95 is a little better, if you can remember all that in the store. (The old 1984 ANSI standard you may remember is dead.)

********************************************************************

My input:

The primary differences in helmets comes from the comfort, weight and cooling properties of the helmet design. Yes, you could get a $30 Walmart helmet and it will more or less have the same safety standard as the $70, $80 or even $150 helmet. But it probably won't fit as nicely, will weigh several ounces more and probably not do a very good job of keeping your head cool. These may not be big issues for you, but if you're grinding up a 10 mile climb in 90+ degree temps the weight and cooling properties of a helmet design might be very important to some. It certainly is to me and that is why I would gladly pay $150 for a helmet that offers the same amount of protection a $30 Walmart helmet would.

Also, as a general rule of thumb if you damage a bicycle helmet in a crash it is best to replace it. Sure, you may not be able to visibly see any damage to a impacted helmet, but bicycle helmets by design are manufactured to absord impact energy. If you hit your helmet upon crashing you may have caused internal structural damage to the helmet material that may cause a failure the next time it is impacted.

Yeah, I know it sucks to have to replace a $150 helmet, but for my money that is a small price to pay to potentially save my life or at least not become a vegetable.
