Everything for a bike
My Beautiful Parking3
Why locals love it
My Beautiful Parking started out as a parking, expanded with rentals and now it seems like they have a whole empire of fixie bikes. MBP is deservedly popular, as rental prices are reasonable and staff dedicated cyclists.
Why you should visit it
There are probably cheaper options out there, but the bikes here are well-maintained and you have many options. They also sell bikes and have tons of accessories. Another recent addition is bike tours of the holiday island Menorca, just a few hours by boat from Barcelona.
It's a bit off a hipster trap, yes, but staff are friendly and the bikes are good. Rentals start at 2 euros.
