Iceland is a rewarding but also demanding locale for a long-distance bike trip. The major hazards are volatile weather, harsh winds, sandstorms, rough roads, and stones flung by passing vehicles. Any bike brought to Iceland should be very high-quality. Bring along a repair kit and be prepared for several flats since supplies are difficult to find outside Reykjavík. Make sure you are easily visible to motorists, and always wear a helmet -- legally required for all children under 15. To protect Iceland's vegetation, all off-road driving -- of bikes as well as cars -- is absolutely forbidden.
Bicyclists along the Ring Road can use the bus as a backup in bad weather. Bikes are stored in the luggage compartment, so you might bring padding to prevent damage.
The Icelandic Mountainbike Club, Brekkustígur 2, Reykjavík (tel. 562-0099; www.mmedia.is/~ifhk/tourist.htm), does not arrange trips or rentals for tourists but the website has suggested itineraries, a packing checklist, a message board, and tips on where to store your bike box.
On Friday evenings from June 10 through August, Arctic Adventures, Laugavegur 11 (tel. 562-7000; www.adventures.is), leads 4-hour bike tours of Reykjavík for 4,590kr ($73/£37), with only a two-person minimum.
