Used bike shops in Barcelona
 

Hello,
I am doing a leisurely tour from Barcelona to Nice and due to the high cost ($150) of transporting a bike on a trans-Atlantic flight I am planning to buy a bike in Barcelona and selling it in Nice. Can anyone recommend or provide pointers to bike stores in Barcelona that sell used bikes?

thanks in advance,
Eric

But are you sure that you want to break-in a second-hand bicycle that you have never ridden before on a 700 km trip over a mountain range?
