What are you calculating the ratio with (What reductions in each stage, and what motor free speed, and speed loss constant?)
I get 3.86 and 9.86 ft/sec with no speed loss and 5310 CIM free speed, for reference.
The stages of reduction are:
12:40 CIM->cluster shaft
15:48 OR 28:35 cluster shaft->shift shaft
16:36 chain
It seems like a lot of chain reduction with 4" wheels. The ratio chosen seems to be perfect for 6" wheels (5.79 and 14.83 ft/sec with no speed loss, 4.69 and 12.01 with speed loss, 46 amp wall-push in low gear)
