"Kinetic energy is the energy an object possesses when it’s moving. For example, a 2,000-pound car traveling 65 mph has slightly more than 283,000 foot-pounds of energy." http://www.vcu.edu/cppweb/tstc/crash...n/kinetic.html

"KE = (.0443*W*V^2)/2 , where:
KE is Kinetic Energy in foot pounds (ft. lbs.)
W is your aircraft's Weight in pounds (lbs.)
V is the aircraft's speed in knots (KIAS) squared (to the 2nd power)"

And here, just for your entertainment, is an online energy calculator. You can use it to determine the kinetic energy of an object expressed in foot pounds. Enjoy!

Well there you go! I stand corrected.

One day you folks down there will take up the metric system and then we'll all be able to understand each other! :p

I do know that there are 40 rods to a furlong, and 504 pints in a hogshead, so I'm learning!

I'll also keep wearing my helmet so I can continue to use my brain in it's current capacity!

I've got this one as my "dressy helmet". :)

Have you corresponded with the folks at Nutcase, Sammy? I met the wife in a LBS here - she is so nice. Her husband designs them, she keeps it all organized. :D

just get the cheapest bell. $35 bucks and so many damn vents you'd think you were some sort of fancy cycling super hero sorta thing.

Goodness! I'm looking for a helmet and innocently clicked on this thread thinking I'd get tips on interesting sites for helmets, maybe some pointers on buying a helmet. Didn't expect the huge arguement since the post was about getting a helmet.

This is the EXACT helmet I was going to point out. Saw it in their newest catalog and thought it was the coolest looking bike helmet I've ever seen.

Personally, I'd probably wear a skate helmet like everyone's talking about but I will DEFENATELY check out the one Winston posted...that's SICK!

Absolutely. Kinda like the people that argue not to wear seatbelts except that seatbelts have been statisticly proven to save lives (I'm one of those statistics) over and over again.

If you don't wanna wear one...cool...but I will.

Yep, this is a great example of a "thread jack". However, some were able to sneak in a couple of sites pertaining to the thread......seems to be some cool choices.

Well, the OP did start out by saying he was concerned about looking stupid in a helmet, and wanted help in finding a non-stupid helmet.

If a fellow started a thread about how he thinks he looks stupid on a red colored bicycle, and could somebody please help him find a red colored bicycle upon which he looked the least stupid, I don't think it would take too long before someone pointed out that he doesn't have to ride a red colored bicycle.

Of course, I'd be lying if I pretended not to know that the mere suggestion that zillions of people around the world get by without helmets just fine was going to rile the helmet Nazis and derail the thread. But if I'd shown up at a meeting of regular Nazis and suggested that maybe Jews weren't so bad after all, would I be the bad guy? :roflmao2:

Six jours,
Not cool. Really, try a better metaphor.

This is not a cool helmet.

The only surprise is how long it took someone to whine.

How are those nutcase helmets for heat? I love the way they look, and I'm seriously considering getting one, but I'm concerned that there may not be enough ventilation.

I like the helmet the bicyclist wore in the Top Gear episode where he beats the car driver, the subway rider, and the boat guy. Not sure what brand it is/was but it looked very cool.

Yeah, well I bet you're not Jewish.

Yeah yeah yeah, everyone's a victim.

Heres my problem, I haven't been wearing a helmet during my commute because a can't find one that fits right. I ordered an XL through my LBS but I couldn't try it on so I'm not sure if it'll fit right. Oh yeah I don't have a huge head, lol, I have dreds so I need something larger. Any suggestions?

I dunno... dreds are kinda styrofoam-like. You kind of have a built-in helmet! Cool! :thumb:

Take a look at this Trek helmet... not real fancy... bit it is very large. It should get the job done.

Yeah they really are. They soak up more impact than you would think. :o


And that Treck helmet looks decent I'll have to look into it.

Get a helmet with HUGE vent holes, then thread the dreds through the vents. :thumb: ;)

The poster said "in the world". The statement may or may not be true for the US, but for the world - remembering the number of people who cycle commute in China and India - it's unquestionably correct.

even in the US, helmet usage is below 50%.

In my MHL province where they fine people and take away their bikes if you don't wear a helmet, the usage sits at 50%

Just because there is a vocal group that loves helmets, doesn't mean everybody feels the same kind of love.
