  2. I have been racing BMX for over 10 years. Trust me it is a very good bike. There is only one problem though… NOTHING. My favorite part about this bike is that it is really light and easy to handle. Its really good bike for anyone that wants to race BMX or go freestyle, its also a great bike for just riding around. Its just not that comfortable for going on long bike rides. Normally it comes in a 24″ rims. Like i said i have used this bike so much that i am accually on my 3rd bike. I would highly recommened getting this bike.

  3. So far my kid loves it he is 4ft 5in 85lbs and he rides it fine. Good to get a bike that every other kid on the block doesn’t have the same thing that they got from Target or Wal-Mart. Rides good has freewill and looks good.
