The FX3 Disc could have been better
I bought it the day previous to my birthday 28, I was happy and excited. I used it and noticed a sound in the chain. When I arrived to my home I noticed that the rear and the front derailleurs where grazing with he chain. Because of lack of time I took it two weeks later to the store. They told me the derailleur were defective, but that I could still using the bike. I did not expect that. I thought that the bike was going to be okay and the part was also warranted, especially when when was just purchased

The Hybrid of my life
I purchased late in the year of 2020, so I didn't get to ride much as it was turning quite cold. I've taken this baby out on a few 7k rides, I'm always exhilarated after my ride through time. This will definitely get you a good workout in, if you're like me... a person who went on gym hiatus due to the pandemic. So I've gained some weight. This Trek Fx3 has reintroduced me to outside workout world. No regrets with this purchase. I sold an amazing race bike for the comforts of a more comfortable ride as I age. This bike won't have you hunched over as much.

Excellent Bike with Quality Components
The FX3 is great for long or short rides around city trails and light gravel roads. This is my first quality bicycle and feels very smooth with excellent components. Easy to shift and brakes that can stop on a dime. The only drawback is the saddle is less than comfortable, so I added a padded cover. I plan to ride a lot more as the weather gets hot and running outside gets too unbearable.
