>>1137038Rigid 90s mtb is probably best. An older quality steel road bike can be good too, if it has rack mounts, but the gearing won't really be low enough, and the wheels won't be as strong as a rigid mtb (also narrower tires means higher chance of damaging a wheel, the no 1 thing to go wrong with a loaded bike). A used touring bike if you're lucky.
Fuji Touring is the baseline new option.
