I measured my 10 and 11 speeds at 21.5cm and 22cm respectively. The dual drives were good but yes I too think they stopped production. My 1x8 with 11-32 doesn't give me the gears I'd like. A 11-51 would be nice...
Check if Sturmey Archer still sell the CS-RF3. Its the same concept as the DualDrive.

I think that the idea behind an IGH mated to a cassette is better than a wide range 1x on a 16" or 20" bike, since it allows low gears, but also high gears without needing an enormous chainring.

I'm personally very happy with my DualDrive, and I think it's a shame they stopped selling it.
