Most of my rides are 1 mile to a store and 1 mile back. I can go up hills without peddaling also.
If you will be riding longer distances and want lower rpms, try a 41t or smaller but you will sacrifice some torque and may need to peddal to get going. If you just ride around the block or short distances the 44t works fine.
I use one of Jim's 38ers and adapter....as well as his new motor mounts and straight shot intake.... I weigh 190 #'s.....all I have to do is pedal a couple times and kick it in...it takes off....it whistles up to around 18 MPH then it's like a turbo kicks in.....my computer tells me I've had it up to 34.5 MPH ....flat road... ( recently repaved )....I've used a 44 tooth on previous builds and they never even made it to 28 MPH.....and the motor sounded like a pissed off chain saw or an incoming RPG....if you don't have any steep graded hills to climb I'd go with a 38......you can cruise comfortably at 25 and the engine is barely above idle.....this also allows you to get a heck of a lot better mileage than a 44....hope this helps....
