1987 Schwinn World Tourist Fixed Wheel Single Speed

How can it be a Fixed Wheel and a Single Speed capable of coasting? Hmmm...Thanks to a Shimano Front Freewheeling System(FFS) which was an abandoned technology which put the freewheel mechanism in chainrings up front instead of in the rear wheel. The idea at the time was to allow gear changes even while coasting. This lugged beauty is fully fenderized with curvy city bars and a 46x17 drivetrain. Coasting initiates a loud ratchet from the chainring and integrated chainguard with a weird 'this bike is pedaling itself' type motion.

The 5 speed gear cluster and Positron rear derailleur and shift levers were removed and the bike seemed relieved.

Great job on the single/fixed job. I just picked up a "female" version and was debating on deleting the positron system. I think the bike could stand a diet =P
