Hello i recently bought a mountainbike, it is very rusty but works fine. How ever the front suspension seems to be stuck. I unscrewed the top part to see if i could solve the problem. But it was completely empty when i was looking down with a flashlight.

Is there such thing as fake suspension just for looks?

This is the bike that i have http://imgur.com/w2gy8FS (pic is taken from google)
I can't seem to find any information about the bike but the name is RONIN FSSP PERFORMANCE BIKE
