there are many ways to rome, but if you are willing to put in some uncompromising effort a serious multigear bike for do it all street use should in my preferance have about 30 gear inches on the lowest and over 100 on the highest.
and not more than 18 percent between gears over 70, no more than 10 percent over 100.
for decent wear and efficiency no less than 12t sprocket on the rear wheel, and max one planetary gear in the driveline.
thats the wish list, and i have fullfilled it on one of my bromptons.
have fitted it with a 2x10 dura ace/shlumpf speed drive 30-120 gear inches. 12 percent max step between gears. needless to say its a highly competent blast.
with less gears you have to compromise, nothing wrong with that.
a drastic example is my 2speed brommie commuter where i have done away with all low gears and have only 71 and 95 on hand. like having only gear 4 and 5,5 on a bwr 6sp, or 2,5 and 3,5 on a 3sp. nothing for hilly areas, but the greatest fun elsewhere.
then the surprice; almost as fast as the 20sp on longer distances in reasonably flat landscapes.
