I think the thing needed for practical winter riding where snow and
salt are the norm is a fully enclosed drivetrain and brake system. Why
has no one come up with this? It would also greatly ease cleaning and
maintenance chores for everyone.

That does exists for decades already, with internal gear hubs or
single speed.

Tricky, as you need to get the heat off somehow.

Internal hub with a nickel plated chain. You don't need a chain guard
if you don't want one. I commuted with this setup for years in Chicago
winters.I'd have an old towel or rag handy and wipe the crap off the
chain when I got home. Wet lube once weekly and no trouble at all. I
like those KMC "heavy duty" bmx chains for winter use with Nexus and
Sram hubs. Strong, cheap, and say FU to the elements.

What he said, but you can even skip the wet lube and wipe off bit if
you want. Comes with internal foot brake too if you want.

Or roller brake. I liked how mine had traditional cantis with Eagle
Claws up front and an ultra reliable roller brake in rear. Another
thing: if it's really cold, moisture in cable housings can freeze and
disable your brakes. I spritz of your choice of lube in the housings at
the beginning of the winter can prevent this. I used to always use it
as an excuse to bring my bike into a pub to warm up the brake lines.
Nothing like a nice pint for the rider either. :-D

Well, they've been made since 1889, but if you can find one it's going to
be expensive.

I like that two speed crankset. Interesting!

What I find interesting is that their lightweight race model in 1890
weighed only 16 pounds. That's not all that much more than modern race
bikes. How?? Is it a typo for 26 pounds?

"In 1890 Sunbeam exhibited some interesting new models at the Stanley
Show. Their lightweight road racer weighed only 16 lbs, and the Light
Roadster weighed 29 lbs. Also on display was the spring frame Sunbeam,
an anti-vibration model. Unfortunately the idea did not prove to be
successful due to the launch of J. B. Dunlop's pneumatic tyre."

Huh? I have a bike like that here. It's about 30 years old, and ones
like it were (and probably still are) as common in parts of Europe as
pickup trucks are in Texas. Fully enclosed chain, gearhub, drum
brakes; all of these things have been around since before WWII. The
reason that you don't see them in the US very often is that most
Americans are wimps when it comes to going places, particularly in bad
weather; they drive *everywhere*, even to a store two blocks from
where they live. Even a lot of otherwise avid cyclists won't ride in
rain...and even fewer in snow. Thus, there's just not enough demand
to make it possible to market a bike like that in the US mass-market
arenas profitably. At least, not yet.
