Find Your Size

Size and fit the most important things when it comes to bike helmets. A helmet that doesn’t fit properly won’t protect you as well as it should.

First, you’ll want to find the right size. Start by measuring the circumference of your head. Simply wrap a tape measure around your head one inch above your eyebrows. Compare this measurement to the Schwinn Helmet Size Chart to find the right size helmet for you.

Adjust the Fit

Once you’ve found the correct size, make sure it fits correctly. Place the helmet squarely on your head so that the front of the helmet sits one finger-width above your eyebrows.

Next, use the rear dial to find a snug fit - right to tighten, left to loosen. You should be able to shake your head without the helmet slipping off, while still feeling comfortable.

Now you’re ready for the straps. Adjust the side clasps to hit just below your ears, forming a “V” shape. Then buckle the chin strap and tighten it so that no more than one finger fits under the strap.

Note: Be sure to check your helmet regularly to insure it still fits correctly. Adjustments may be needed now and then due to use.

Style of Riding

When shopping for a helmet, you’ll also want to consider the style.  Are you a purely recreational rider, a road cyclist, or do you like to take on rugged mountain trails?  There are helmets for each one of these categories, which are tailor made for each style of cycling.  For example, road helmets will be very light weight and aerodynamic, whereas mountain helmets are more likely to offer extended coverage in the back.  Consider what kind of riding you like to do and make sure you get a helmet suited for that.


There are lots of features to consider when looking for a new helmet – and that’s the fun part! If you live in a warm climate, you might want a helmet with lots of vents. If you like to ride in the early morning or late at night, a helmet with a rear light is a great choice. And then of course, there are a myriad of colors and designs to choose from.

A bike helmet is an important part of any ride, and with these guidelines you should be well on your way to finding the right helmet for you.
