I wouldn’t want to get into thread drift so a separate thread might be best to answer the question above.Jupestar wrote: ↑22 Jan 2022, 7:57amInterested in how these ride. I’ve been tempted to try either the 2 or 3 speed SA.

They are not close ratio and their overall range is limited but they are reliable and by picking the overall ratio wisely they make a good commuter.
The only thing which has stopped me pushing ‘go’ on the 2 speed is I’d rather the direct drive was the higher gearing. Then I wouldn’t need to swap the chain when changing wheel from SS. 3 speed I’m tempted with.
Briefly, SA sprockets are available in sizes of 13 to 22 teeth inclusive so I’d have thought one of the available sprockets would match the single speed arrangement being used. Using the same size sprocket (as the SS) would give gears of ‘low, normal and high’. The SA AW uses traditional freewheels inside of it and hence their drive isn’t spongy; the ‘middle’, ‘second’ or ‘normal’ gear is (inside the hub) a direct drive so no gear train is involved. ‘Fixed gear’ SA’s are available too but they’re not common and, if needed, others can tell you about them.
