Bicycle and repair shops

 

Bicycle stores are mostly to be found around Reykjavik. There one can find most spare parts, equipment and general repair service, and even get boxes to pack your bike for the flight home:

One can not expect to find all spare parts or tools in the countryside, so it's advisable to bring your own or buy all the necessities before leaving Reykjavik. It is hard to find bicycle repair shops in the countryside but service stations or garages for cars are to be found in most villages where one can get help (if needed) and repairs.
