Nothing special, just riding trails and roads that are somewhat hilly. Currently I have a range of about 1:5. A range of 1:3 will cover my existing 2.2 to 3.8 gear combinations. A range of 1:3.5 will cover my existing 1.3 to 3.8 gears .

I think I can live with 1:3.5 internal hub or a 1:3 internal hub and two chainrings.
