Men's 26" mountain bike

I can't take an actual picture of the mountain bike because i don't want my step dad to know I am selling it , it's my bike but the seat is too small and it came with no air pump for the tires I bought it $187.00 with shipping it cost me $207 but I'll sell it for $120 or trade for a good gaming chair that is like an office chair that will take my weight and won't brake and is already assembled together or I'll take a PS4 destiny edition used but works with the power cable don't need HDMI cable I already have a few of those or I'll take a modded 3DS
