OK. So I found out that at 5000rpm I can get 43mph with a 20t left jackshaft gear, and a 43 t chainring, 13t right jackshaft, and 43 chainring for the rear drive, and a 15t for the rear. Question is the pedals become 180rpm. Is that ok?? If i use a 30t left jackshaft, 13t right jackshaft, 43t chainring, 60t chainring for rear drive, and a 15t for the rear, I get 40mph and 123 rpm. Do i really need 61rpm?? Which option should i choose. If i pick B, it will cost more for the 60t gear and the 30t sprocket but i can deal w/ it.Crazy Dan. I don’t need any more gear ratio stuff now. After 1 hour I created my own gear ratio calc that can be viewed by anyone with an internet connection.
