Yes, I have a bike I sometimes ride with exactly that same gearing. Cyclists don't often use units like 2.66 gear ratio; we prefer to put it in terms of gear inches, which you can easily calculate
H E R E. Your 48 x 18 gives 70 gear inches, a very good compromise for general fitness/fun riding on pavement anywhere the terrain isn't super hilly.
