Default Re: Chinese frame mount Engine Gear Ratio

wildemere, here you go as a .zip The jackshaft values of .000001 are hidden on the HT sheet. Had to do that to eliminate a divide by zero error and I made the book for the jackshaft first.
datz510, Yes, I found metric circumference tables for bike tires on line, applied a formula to that table to gain circumference in feet. The table is included in the workbook as a separate worksheet.
I'm looking to use the Robin EH035 on my cruiser. Just ordered the bike today from Worksman. The EH035 has a top end of 7500 rpm. I'm exploring various gear reduction options (Grubee, Staton & pocket bike boxes)
