  • Perfect for my 9 year old son. He loves everything about the bike from the look to having a kick-stand. I will say it is a little bit heavy but the plus side is he is not trying to pop wheelies with it. I wanted a mountain bike that he could take into beginner trails and the size is perfect for the next couple years. I did not want spend too much on a transition bike so the $124.97 price was perfect.
  • I’m pleased with this bike. It’s a decent weight and good size for my 8 year old. All the components seem sturdy as well. Also easy to put together
  • Definetly a nice looking bike and great handling My 8 year old can go up hill with ease now!
  • Perfect size for my son. He loves it. Project handle stem want bet but my husband was able to work with it.
  • My 11 year old loves this bike. Came shipped in a few days after ordering. Putting together was fairly simple with the directions(I’m fairly mechanical). The only issue was with the derailer. It was hitting the spokes when shifted. I found that the mounting bracket was tipped in a little so I carefully bent it out a little. Problem solved. The small screw adjusting of the derailer took some time, but came out well.
  • The bike works well for my 9 year old son. Easy to assemble CONs- arived late, had some body scratches that were pretty noticable, and one of the gears is not working after only using it 3 times.
  • My son god this bike for Christmas, He was shifting the gears and the part you turn just broke we returned it and got a new one same thing happened again the gear broke
