Ok so i have this old.... well mid school? Haro Revo. and since its pretty old, its got a 44-16 gear ratio. I used to ride it heavily up until recently because i built a new bike with modern 25-9 set up and wanna do more lightweight stuff. so im letting my girl use it. what, in anyone's experience is a good gear set up for an old bike thats easier to pedal than a 44 16 but not as spinny at high speeds as 25 9? I was thinking 33-13 but is that unusual? or bad? let me know whats best

33/13 will be easier to pedal than 25/9. Up it to like 28 or 27/9 to get the results you seek

so 28/9 will be easier to accelerate from a stop than 44 and will have a higher top speed than 25?

Get this in a 42T for your girl.
42/16 =2.625
https://www.danscomp.com/products-PARTS/457068/Profile_Imperial_Sprocket_36-46T.html

44/16 = 2.75
25/9 = 2.77777778
33/12 = 2.75

These we're all the stock gearing for bikes for the longest time ever. 25/9 is actually slightly more agressive then 44/16 so 25/9 is less spinny at high speeds the 44/16. (You probably just have a better wheelset on your new ride)

44/16 and 25/9 are very comparable.

What you would want is either larger up front, or smaller in the back.

So 27/9, 28/9, and so on. If you don't want to spend the cash to drop the back wheel down to a 9t (new hub or wheel minimum), then you could find a 45t or 46t sprocket to make it harder to pedal and ultimately higher top speed.
