KOGA WorldTraveller

The WorldTraveller breaks the steel habit of this list on purpose. KOGA builds the rear rack into the aluminum frame itself, rates that rack for 45 kg (about 100 pounds) and the whole bike for 180 kg, so there are no rack bolts to work loose on a long rough descent. The Rohloff version adds a Gates belt in place of a chain, which a German magazine test found practically maintenance-free over long distances, though a broken belt cannot be patched at the roadside. That test also found it very heavy at almost 23 kg (about 50 pounds) and little use to an occasional rider. The Rohloff model costs about €4,699; derailleur versions start at €2,499.
