gear reduction box

Rotax engines have a gear reduction.general aviation engines (lycoming and continental )not.
This is a question that I ever wanted to ask: Why ?
I mean that I know a reduction gear box allows a fast rpm engine to let run the propeller at lower and more efficient rpm. I also know that in bycicle if you use a lower front gear and bigger rear gear you can better climb (same "monk" power but higher efficiency and lower speed).
Question:
does the gear box allows :
- increase power to the propeller and keep same torque ?
- increase torque at the same power ?
- increase torque and power ?
- non of above ?
Anybody is able to explain it to me ?
