The gearing is rather low and goofy, but just needs a $5 17T cog switch.

For sure get a 3 speed. The middle gear is the same as SS. They are fun, efficient and seldom have any problems at all. An annual lube is all that is needed. My SA 5 spd has 10,000 miles with many century day rides. A drum brake in the front is even better, mine has 20,000 miles.
