Bikes require maintenance. More complex bikes require more maintenance.

Though it's worth emphasising that this is complexity at the user level,
not the underlying engineering level. A derailleur is mechanically much
simpler than a multi-speed hub, but since there isn't really much that
can be done at the /user/ level (change up, change down, maybe move a
toggle chain in or out a notch and that's about /it/) the hub is
effectively a simple thing. Ditto hub brakes and dynamos, which just
sit there and work on request rather than needing constant fiddling.

Changing the gearbox isn't the answer to being overtaken when

I have witnessed people riding tandems with bar-end mounted drag brakes
unintentionally have the brake on.

I Have A, Um, Friend who once took the trike to the supermarket, loaded
it up with a ton of shopping, and cycled home with the spoon brake still
on, rubbing the tread off the rear tyre.

Mind you, it's only about half a mile from the supermarket to my
house, though. My, Um, Friend's house, I mean.

A bogus as bogus can be test suggests, empirically, you can expect this to

With a derailleur setup, commuting on dirty roads, it's going to need a
clean, lube and adjust once a week at least. With a hub-gear setup and
a full chain case, once every three months or so should do. Obviously
if you have the hub gear but no chain case then your chain is still
exposed to all the filth of the roads, but a hub gear chain is both
more robust and less cruelly treated than a derailleur chain so once a
fortnight would probably do.

Not necessarily. I have rapidfire and that changes up to 5 gears at a
time. It depends on the model. You may be happier with gripshift.

Interesting. When you say it changes up to 5 gears at at time, do I
take
it that you're going pump-pump-pump-pump­-pump five times in rapid
succession... and that the chain them snakes straight over five at
once?

Or is there some clever switch that goes "gimme five" ?!

My thumb. I push in once, a short way, and it will change one gear.
If I push in a bit further it changes two gears.
The maximum change I can get is five gears in one push.

That does me fine on a normal MTB cassette.

 Cool - I Like it!
Is there a technical term for this kind of gear changing action?
Are they very expensive?
(No one mentioned this type of thing in a shop so far... maybe
they'll be overly pricey - or heck maybe most Shimano derailers
can nowadays do this for all I know. But thanks that sounds like
what I need for stop starting in town.)

At 20mph (a good speed on the flat if you
can get there) the difference sitting up would make in my experience
is:

drops -> hoods, drop 1.5 mph
hoods -> top of bars drop 2 mph
sit right up no hands drop another 1.5mph>>>

Ah now we're getting somewhere!
That's interesting.
Except I'm not sure I understand the tech terms.

"Drops" means dropped handlebars, right?
the racing style handlebards... okay.
What are "hoods" - some bit of gear racing bikes have
that you can stick your hands on ?

And so adding it up you're saying that going from Drops
to having your hands on the top of the handle bars costs you
3.5 MPH - that is from say 20MPH right down to 16.5 MPH.

Well, you're the expert... I guess you have a speedometer
on the bike right? But I do find that AMAZING! But yeah, maybe
that's the reality.

What about tyres then - medium fat smooth to very thin tyres.
Both pumped up rock hard... how many MPH?! (@20-ish MHP)

The top of the brake lever mounts.

If not more.

That's the facts, jack.

Trivial. Depending on the roads. If they're rough enough or unpaved the fat ones
will be faster.

My trike [1] has an elastic band on the handlebar for a parking brake.

On smooth tarmac, 38mm slick to semi slick, lose 1 mph. To knobblies, lose 4
mph.

I did swap my slicks for knobblies this morning, but that was down to the
snow and ice, and the knobblies having metal studs in..

The trike (which rarely gets used for commuting) does, but since my grate
