I have the 16/19 freewheel and use common road 36 and 39 tooth chain
rings in a double/double set up. I get a 51 and 66 inch gear out of
that with no movement in the dropout. I have this on an old 80's
Raleigh USA frame with somewhat short dropouts and the "extra" is used
just for chain wear. On my soon to be new Simple One (actually five) I
plan on the 16/19 and probably the 40/32 and a 22 tooth flip side
freewheel. I live in a hilly area so I have no need for higher flat
land gearing. This combo should give me all the range I really need on
my normal solo rides. On my geared bike I have a Mountain crank with
12-32 cassette and I get a real crawler out of that but admit I could
just as well dismount and walk using different muscles and at the same
time give my crotch a rest. Its not unlike the old TDF guys used to do
back in the 20's or whenever before derailleur gearing caught on and
they had to repair all their own machines.  I once tried a local hilly
15 mile road ride with just my 51 inch gear and it wasn't any slower
by much. My energy was used in the climbing. I coasted on the down
hills and spun, spun coasted on the flats. It was actually fairly
relaxing. I wouldn't allow myself to shift to the higher gear on the
flats and I could easily pedal 10-12 mph with that low gear. I see
kids riding their BMX bikes this way all the time using the spin, spin
coast approach.....only difference is, I have a saddle at the proper
height. I think the new Simple One will be a fun bike to ride.
