Mountain

When the lure of off-road adventure calls, a mountain bike is an essential piece of equipment to maximize the experience. A distant cousin to the road bike, these knobby, wide-tired bikes don't flinch when it comes to tackling all manner of variable terrain. As the popularity of mountain biking has continued to rise, so have the evolution of bikes designed to tackle specific tasks. 

This has led to a very common question we get at our Peachtree City and McDonough locations:

What type of mountain bike is right for me?

Do you want a hardtail or full suspension bike? Is a 27.5" frame better than a 29"? Carbon fiber or aluminum? These are all questions our staff is well-equipped to answer!

One of the most logical starting points to determine the right fit for a mountain bike would be our Guru ExperienceOur state-of-the-art, computer-controlled GURU DYNAMIC FIT UNIT™ (DFU™) adjusts your riding position in real-time to maximize your comfort and efficiency. At Atlanta Trek, we also offer a unique mountain bike tune-up program that will ensure your bike remains in excellent condition, no matter how difficult terrain.
