Bicycles, like shoes, come in sizes. The best bike for you will be one that fits you and your intended riding style. I have no way of knowing either. What makes you think that this is the right one?

Buy It.

Ride it.

Take some pics to share.

In my opinion this bike is built for speed. correct me if im wrong but that is what im going for.

Also what should i look out for when buyin a second hand bike? what parts should i check?

It's a MTB so not built for speed on the road.

Worn or old tires, wheels straight, dents in the frame, does the wheel or crank wobble, is the front fork rock solid in the head tube? Shark teeth on sprockets.
