Default Gearing? Cut those pedals off!! ?

im a new member, owner for about one month, and ready to make a new one, but i need some help

i was thinking of getting a Beach Cruiser, putting mountain bike gears one it, cut the crank and pedals off and leave the gears and shaft, and on the left side of the crank mount the stock rear gear that comes with the 80cc kit.

with some rough measurements and some rough figuring i came up with these Ratios for the new drive train

Stock kit setup 6.75 : 1

Moded Crank
Lowest gear 7.425 : 1
Highest gear 1.2 : 1

and i would have to rig up some sort of way to pull start it
any thoughts guys?
