It is a light frame and is great for beginners. In the long run, you are obvioulsy going to change things. On mine i change the front rim, chain, grips, forks, stem, and tires. But, i made these changes after about a year or so.
Some of the parts are breakable and heavy but it is a beginner bike so whadda ya want.
Great for beginners, light, easy to work on, very customizable.
