Bike Helmet(头盔) Safety
Bicycle riding is about as safe as walking. But when you’re riding in traffic or down a mountain trail, it can be dangerous. Wearing a safe bicycle helmet correctly is the best way to protect your head in a crash.
Helmets have changed over the years and there are helmets made for lots of different activities.
To choose a helmet, first find the size of your head where a hatband or sweatband might sit. Use a fabric tape measure or a piece of string and measure it with a ruler.
Adjust the helmet so that the front edge is level across your forehead, and 1 or 2 fingerbreadths above your eyebrows.
Finally, look in a mirror to check your work—and make sure you look great! Things can shake a bit as you ride, so you may need to adjust a bit along the way. And remember that for most helmets, once you’ve crashed, the helmet is trash, and it’s time to get a new one.
Alright, make a quick summary:
| A．Straps often loosen. |
| B．So it protects your head and face. |
| C．Then check if the helmet suits you. |
| D．Next, make sure the helmet’s not on backwards. |
| E．Select a helmet that is safe for biking and fits your head. |
| F．Some are multi-purpose, but they may not be made for riding. |
| G．If you feel a bit of tension when you speak, you’ve done it right. |
