How can you remove logos from a bike frame?
It's almost certainly stickered if it's a cheap bike, plus laser etching is usually reserved for bare metal frames - Titanium in particular. Cheap or not, it's still probably got a clear coat over it, and that sticker is almost certainly underneath the clear coat. Unless you're prepared to strip it down to raw metal, prime it, and paint it, you're probably better of just leaving it as it is - especially if it's a cheapie.
