Torque is also important, especially for climbing hills or navigating rough trails. I learned that a well-tuned engine can make a significant difference in my riding experience.

Durability and Build Quality

I found that durability is essential, especially if I planned to ride in rugged conditions. The frame material and overall build quality can affect how long the bike lasts. I paid attention to reviews and feedback from other riders to gauge the reliability of different models.
