Well now I can see :'( . I have already inspected the frame and the only damage that I found is on the photo below:



I paid for bike 80€ . Now the seller told me that I can return bike and he give me back my money or he can give me 30€ back and I can keep the bike. Here I need your advice, because I don't know what to do. If I decide to keep a bike, I will use it as " commuter bike " .
