They say you never forget how to ride a bike, but what about bike rides that are unforgettable?

It's National Bike Week, a great excuse to hop on a two-wheeled vehicle asap. Especially because bike commuters report lower stress levels and greater feelings of freedom and relaxation than those who drive cars to work. And it benefits your little ones, too; kids who cycle to school are associated with lower odds of being overweight.

This time, give your bike the appreciation it deserves by taking it on one of these exotic and adventurous bike trails guaranteed to awe you.

This iconic highway connects the two major Vietnamese cities of Hanoi and Ho Chi Minh City, and cycling it means you travel the length of the country. The journey is roughly 700 miles and takes approximately two to three weeks to complete. But it sure is worth it as you travel through rural villages and beautiful and lush foliage of the coastline.

2. Great Divide Route, U.S. and Canada

The Great Divide Mountain Bike Route is America's premiere cycling route, spanning from New Mexico all the way to the edge of Canada. And if that sounds pretty long, you're right — 2,700 miles long. But on your way, you'll see some great Americana landscape: the Great Divide Basin in Wyoming and Boreas Pass in Colorado, to name a few.

In Noongar Aboriginal, the name of this approximately 621-mile-long off-road trail means "path through the forest". And it sure lives up to its name, as cyclists travel under eucalyptus forests and spy indigenous wildlife, like koalas.

Although this route is shorter than the others, at 37 miles, it doesn't make it any less rewarding. This route takes you over six small islands in the Seto Inland Sea. Yes, you read correctly: island hopping. It makes for a great day trip.
