    Comments about Mantis Grizzled 20" Boys' BMX Bicycle:

    When the bike came it looked really cool! It was pretty easy to assemble except a little trouble with the seat. but it was ok. WE also had to pump some air into it. It was much lighter than many bikes. It rid well and was nice. The problem was the chains. The chains were too loose.It kept coming off if I went too fast, But I got it to be tight somehow but I still need to be carefull with it. But other than that, it's a good,smoothe ridng,Cool looking bike.

    Comments about Mantis Grizzled 20" Boys' BMX Bicycle:

    This was advertised as a 20" BMX type bike with no other measurements. However, the frame is smaller than your average 20" bike because my 12 yr old looked like a giant riding on it, and his knees were hitting the handlebars. It might be a great bike for a kid who was 8-10 years old, but they'd outgrow it after that.
