Is there a difference in bicycle helmets?

I am looking through a bicycling catalog and the prices range from $25 to over $150 for bicycling helmets. I would assume they all have to meet guidelines for protecting your head - surely the more expensive ones will not protect it 5 times better. There seems to be a thing about the number of air vents. I notice the weight between them all is nearly the same. Other than air vents, what advantages would I notice as a user if I went with a mid priced helmet over the cheapest helmet?


Answer
Weight, venting, and marketing make up the biggest differences in the cost of helmets. Helmets must meet the same standards, so the function of all the helmets is presumably equivalent. However, one way that manufacturers make some models less is expensive is to make less sizes. For example, using 2 molds instead of 3 saves the company development, manufacturing, and distribution costs, but it means less size options for you to get a helmet that fits well.

When it comes to comfort and safety, a good fit is the most important factor. More expensive helmets tend to come in a larger variety of sizes with more control over chin strap and back-of-the-head adjustments. I have found helmets with tensioning systems on the back of the helmet to be the most comfortable and to have the most secure fit.

Definitely go to a bike shop with lots of models and sizes in stock, and then try on a wide variety of options to see what fits your head and your wallet best.

How much speed will I lose on average if I wear a bicycle helmet? So far I average about 35km/h without one?

Making your head bigger I assume there is more air resistence that will cause drag reducing my speed. I'm planning on buying a helmet this month because I do a lot of dangerous night riding.

Lets see the pros wear one on every ride. And , they care about 10ths of seconds per ride. It actually should make you faster. While it is bigger the curved symmetrical shape should be more aero. But, lets face any speed gained or lost is insignificant relative to the safety issue.
