hi. i'm going to be travelling and working on farms in spain for three months and i wanted to buy a bike once i got there. is there any sources i could look into? i'd like to buy a used bike if possible as new bikes in europe are very expensive. i'll probably be flying into madrid first. any bike stores. used bike possibilities you know of? do you think it would be a better idea to go to amsterdam to buy a bike, and then fly to spain? is there a better chance of getting a used bike, or a better price on a new bike in holland? any information would be most appreciated. thanks.
