It's a well known fact that Barcelona is an easy city to move around in with non-motorised wheels. Bikes, rollerskates and blades, skateboarders, they all know what they're doing. The city is on a very slight gradient towards the sea, so if you can get it just right, you can get some pretty awesome routes going on. It's often I'm asked about how to rent "one of those red bikes that are parked everywhere" but Bicing is only for residents, leaving a few of the local rental companies, all of which vary in quality and reliability.
Barcelona Folding Bike with a fresh new concept. Located in the Raval, the shop has a very cycle-friendly-history, and use to belong to a fairly famous Spanish cyclist Jordi Nicolas - see trophy cabinet and black and white pics on the wall here below. The shop doubles up as a workshop, where David and Juan spot check each and every bike before and after rentals to ensure they are in tip-top condition. Also, the great amjority of their bikes are literally brand spanking new, and look more than equipped to tackle the streets of Barcelona. The prices are very competative considering the amount of care and attention these lads are putting into their jobs.
Apart from this, the guys are also offering tours with an English/Spanish guide and a free drink to boot! Their classic tour guide (pdf link there) takes in almost all of the classic Roman monuments from Barcino as well as a quick look at the more modern touches of the city with Torre Agbar and 22@. Tours leave every Wednesday at 9:45am.
To rent any of the bikes, all you need a valid form of ID and a fresh pair of legs!!
Disclosure: A friend of mine owns this business, but I'm not being paid for this post, rather think that it's a pretty cool business idea and I'm just helping put with publicity. ;o)
