Love the bike, high quality for a great price. Definitely best for not breaking the bank.
Great bike!
I ordered this bike after doing some research and looking in some local bike stores. I loved the price range and also what the bike had to offer. I’ve had the bike for less than a week and I am already obsessed with it! It handles all types of terrain, easy to maneuver, not super heavy, and it’s very beginner friendly. Such a great bike to get into the mountain biking world and into the beautiful outdoors! I would recommend this bike to anyone who is looking to give mountain biking a try! 100% worth it!
