This book was a good. I liked it because I am in BMX and I like riding bikes. If I ever quit BMX I would go to the park to ride. That means I will go to skate parks to do tricks and try and get good. The reason I picked this book is because since I am in BMX. I won the Dakota cup three years in a row and that is had. I get really motivated when I read this book. So that kind of goes with this book because the stunts are hard to do. In this book it talks about what’s extreme, the history of bicycle stunt riding, getting gear, where do I start, getting started, safe biking, bicycle stunt styles, and competition. I have to do most of these in BMX ever year before it starts. So if you want to get into BMX read this book.
