If the diameter (including tires) is 38 inches, a 1:1 crank to rear cog ratio would give 119+ gear inches.
A 1:1 crank to cog ratio (based on a 38 inch wheel diameter) is 40 gear inches... 119 gear inches would need a 3:1 ratio.
At a glance I am guessing that this bike has a gear range in the mid to high fifties... getting it up top speed would take a little work but once rolling I can imagine this bike rolling over everything.
The 28's on my roadster are like that.
