Andre Albert (verified owner) – April 1, 2024

At 6 years old my son was looking a little big on his 16” bike (another brand). He wanted to be able to “change gears in the trails and have shocks like daddy”. This bike has exceeded my expectations and at an amazing price point. He was beyond excited to break out that box and help with the build, and get out on it as soon as he could.
