freewheel hubs .. I have used a series of spacer swaps on the axle to let the hub be re centered to the right to make a 1 speed re dished wheel
loosened tighter right side tightened the left spokes to make them near equal..
The White Industries (Petaluma Cal) makes a 2 (Uno, Dos) cog freewheel ..
math will tell you how big a gear you want in front.. knowing the gears you use on your other bike.
another concept a 3 speed Internal Gear hub. and 2 chainrings Rear D becomes a chain tensioner , that lever can be used to shift the hub.
