And again with a 26" rear wheel and a 20' front wheel, you are always riding down hill.

Adding still another reason. I have posted this on some bike forum a while back. When I put the 26" up grade on my TerraTrike it raised the seat about and inch and lowered the BB about and inch also. I like that because when pedaling, it lowers my knees pretty much out of my line of sight, and keeps them from flashing in my face as I ride.
