I am looking at buying the Cruiser. I live in a hilly area. When I look at Terratrike chart for gear inches I see this available on the Cruiser:
16-116 Gear Inches With High Speed Drive (2.5 Overdrive) 27 Ring & Stock Cassette
Otherwise, stock is 18 through 90.
What is this option about and what does it do to the cost? I would like the lower end of 16 (or even lower, I'd love 10 to 15) but don't need the high end so much. Any other way to get a lower end?
