My wife and I participated int the 3/24 St. Simon ride.
For the most part the program was excellent. However the single speed foot brake bicycles were a bad fit for the island.
St Simon Island has narrow sidewalks where the bicycles were driven. Within our group of 20 we were tightly packed when stopping and starting and crossing intersections often with vehicle traffic.The foot brake was always in the way. Trying to stop was often difficult as the peddles had to be positioned properly so you had a good back stroke. When someone in front of you stopped unexpectedly and your peddles were in the wrong position the only way to stop was jump off.In a similar fashion when starting you could not put the peddles in the position you wanted.The sidewalk/bikepath was very narrow. The handle bars were very wide. This made it awkward when encountering oncoming bicycles and pedestrian traffic,If a single speed bike was needed then the bmx style with hand brakes and free wheeling peddles is the way to go. At the very least a foot brake style with a single handbrake would allow you to control stopping.
