So my landlord, who turns 70 years old on Thursday, is looking to buy a bike, mainly just to ride around town for dual purposes of fitness and decreasing his environmental footprint. I think a modern internal-geared bike (with either SRAM or Shimano Nexus drivetrain) would make best sense for his needs, but I'm finding that major companies, such as Trek, don't make internal-geared bikes. I've not done much searching on this topic yet, but does anyone have a list of links to manufacturers that market bikes with modern internally-geared drivetrains? It'd probably be best if he could buy something local, for the sake of getting fitted and test-rides and everything. Thanks.
