Selling a bicycle in Iran (or turkey)

[Greentravelbug]

I am about to buy a bicycle, but since I have a deadline to go back home, I might have to sell it before I continue traveling overland by public transport. Before I buy, I would like to know if it is easy to sell a bike in Teheran (or maybe Istanbul). Any other Iranian or Turkish cities are good as well of course.
The bike will be a decent one and I will pay around 200€. I don't expect to sell for a lot, I would just be glad to get something for it

Does anyone have any thoughts or contacts?
