If an EA3 26" wheel It is a British 3 speed standard for decades .. nothing wrong with it.
you can modify the drive train simply to gain a really low gear range, though not inexpensive,
Florian Schlumpf of Switzerland has long made their Mountain Drive crankset in their Machine shop.
it is a second planetary gear the reduction gear is 150%, so 3 speeds become 6 speeds
by going thru the 3 gears , twice, the chain remains on the chainring and cog.
so it is as if you had a 50t_20t double chainring, the crank turns faster than the chainring.
low in high range has high in low range as next gear in the sequence . [I have one on my Brompton]
But we seem to have folks who want to tour on their fixies, one gear,
and renowned author, and adventurer Dervla Murphy says she simplified her bike for reliability
before setting off to India , from, Ireland ,,as she wrote in Her book 'Full Tilt'.
