I saw a TV show about an aero professor trying to perfect wedges or
airfoils that would ride on the helmet straps in front of his ears to
attenuate the noise of the wind rushing by.  He had yet to achieve
success.  

Has anyone seen anything that DOES make it possible to hear anything
while going 20 mph on a bike?  Perhaps earmuffs of microphone foam?

It has occurred to me that if helmets extended down over the ear,
instead of sitting on the top of the cranium, perhaps that noise
would be less.  This would be a safer situation, since often the sense 
of hearing is the only thing that lets you know of impending danger.

While I'm wishing, is there any way to hear well AND listen to headphones?
Hey, I'm hard to please!  I want to listen to hard rock at 85 dB, yet
detect the slight rustle of that Dobie moving through the weeds with
murder in his eyes.

I can second that. I had an incomplete fracture of the right big toe
and was told not to run or walk a lot. Bicycling was ok, but i had to
wear an adhesive correction tape and also *stiff* bike shoes. The last
three weeks i rode my MTB on road for not stretching my luck too far ;-)

It's almost exactly 11 years ago that I broke my right foot. It was not
a complete fracture, just the rightmost middle bone was broken like a
fresh branch or twig.
I was able to cycle with a plaster around the fracture. This was
especially easy, as the area where I live is rather flat.

If You don't have to take steep climbs, You can use Your other foot
to do most of the pedalling and use the damaged foot to put just enough
pressure on the pedal to move it downwards.

In the place where I grew up, there lived a guy who cycled with only one
leg! He had his bicycle modified such that the two pedals weren't
opposite to each other but at an angle of about 90 degrees.
When the usable pedal was completely down, the unusable one would point
forward. A spring was attached to this that pulled it backwards.
So, when he pushed his pedal down, it would stretch the spring; when he
would release the pedal, the spring would pull the other one back,
thereby raising the used one. Again, it's rather flat over there.

I'd say, if You place the heel onto the pedal and try to use Your other
foot most of the time, there should be no (major) problem.

BTW. I'm no doctor nor anywhere near a medical profession (all I heal
are unwell computers B-{)! This is my personal view only. I cannot
accept any responsibility. Better confirm with Your doc!

Thanks to everyone one who replied. I think I will be getting a more
serious bike for my 8 year old and give it a go. For those who asked,
the bike I mentioned was a Giant with 24 inch wheels and a 15 inch
frame. The bike is not listed in the 93 catalog but is in the 92 book
and my local dealer thinks he can get it. Hopefully he can. If not,
I'll probably modify a mountain bike for road use. I think my son will
enjoy it. He rides his current bike all of the time and he even ASKED
for a helmet instead of me insisting he wear one.
Oh yeah, again for those who asked, the Giant bike is not a great one
but better than the deparment store bikes. It sells for about $200 and
has some alloy components like wheels but steel bars and stems. The frame
is a high carbon steel. At the rate kids grow out of them, this should
do for the short period of time my son would be riding it and I hope to
upgrade as required. Thanks again for all of the replies, stories and
experiences I recieved.

There's something to be said for a deeply ingrained response to
danger. If you have to think "Oh gee, I'm falling, I should relax
now." [splat] It's too late. Falling in a such a way that you
habitually dissipate the energy instead of trying fight against it is
much better but it is much less instinctive (for some, maybe most?)
than the latter. (Of course, if you try to dissipate the energy
through your head, you're not going to last long either. There's a
right way and a wrong way :-)

I believe that you can train your body to respond in this way. It will
probably take a long time and lots and lots of practise.

I was headed north on Hwy 1 just past Marshall in Marin County (= narrow,
twisty, rolling road) when some jerk in a motorhome tried a passing trick
I hadn't seen before: he pulled over the double yellow line into the
lane for oncomming traffic and just stayed there until someone appeared
from the opposite direction, at which time he returned to his proper lane.

Since he'd pulled this stunt just as we were cresting a hill, and my bicycle
has a somewhat easier time with twisty descents than his motorhome, I was
still beside him when he decided he'd had enough of playing chicken with
whatever was around the next bend.  I was of course expecting nothing real
bright from the guy by this time, so I hit the brakes when he started over,
and nothing untoward came of it.

The oncomming vehicle the jerk driver narrowly avoided hitting was another
bicycle.  I bet its rider had an even more exciting time of it than I did.

For those who haven't tried this -- don't.

1) The 24" wheel front forks won't fit over the 700C.
2) The small bikes front brake would need to be removed if it would.
3) Because the two pedal sets are not syncronized the bike
flexes rather radically back and forth as the two riders bob in
separate directions.
4) This whole thing wouldn't work with quick releases in the first place.
5) it probably would only work with extra long solid axles.

That reminds me of a rather "memorable" ride that I had once.  I was about 25 
miles from home when I rode through a patch of puncture vine.  I replaced
the rear tube with the spare that I was carrying only to find that the spare
also had a hole and that the front tube was also going flat, and that the 
front and rear tubes both had several holes.

Anyway, I eventually used up all my patches (5 of them) and I still had holes
left to patch.  That was when I decided to try what Jim suggested.  I found
a piece of broken glass along the road and cut a patch out of the worst tube
that I had and used the last of my glue to patch the remaining hole.  Since
the patch looked like it might work, I reinstalled it and pumped it up. 

With that patch I was able to ride the rest of the way home without being
forced to call for help or find a ride - yes, I am an independent type!  The
next morning the tire was flat again, but it did allow me to get home, so
I can attest to the fact that Jim's method will work on the road as an
emergency patch method - provided you have glue, a spare tube and some way
to cut a patch.

Don't forget that cats can turn around while "in-flight".  This is a
complicated procedure which requires transfering angular momentum from
one set of paws to the other and back again.  This is often used in
Physics text books to demonstrate that it is possible to change the angular
position of an object in complete isolation without violating the conservation
of angular momentum.  The injured cats may simply not have had enough
time to get their paws downwards.

A couple of years ago I tried stuffing foam/cotton (the foam I used was just
from leftover padding strips from my helmet) in my ear, primarily to
alleviate eardrum pain from the cold wind when the temp gets below 50 F or
so (yes it's that time of year again).  I did notice that, although the
plug reduced the overall noise going in my ear, it blocked wind noise more
than other ambient noise (e.g. car tires), so the S/N ratio actually
improved.  I have since abandoned the foam in favor of a simple wide
headband which I wrap over the ears; I simply switch to heavier headbands
and earmuffs as the temp gets colder.  They protect my eardrums just as well,
and have the same effect on noise, but are not so easily lost.

Since the question was prompted by falling off of rollers, I will start by
giving a tip I learned a few years ago.  When you are learning to ride
rollers, it is good to place the rollers in a door frame or next to a wall
where you can reach out and lean on something solid if you start to slide
off of the rollers.

When riding rollers, uneven pedal strokes certainly are easy to detect.  
I have found, however, that most instability in riders is not related to
an uneven pedal stroke but rather to a tense upper body.  When the upper
body is tensed up and the arms are locked, the upper body tends to sway
side to side during pedaling, and the locked arms transmit this motion
directly into the bars yielding steering motion.  It can be particularly
hard to relax when learning to ride rollers and worrying about falling
off.  Without relaxing, I don't believe it is possible to build a fluid
pedal stroke or to ride rollers comfortably.  The tense upper body and
stiff arm syndrome is very common.  Ride in any large group of recreational
riders or lower category racers and you will see many examples.

One technique to work on a circular pedal stroke while riding in the
saddle is to pedal with only 1 leg at a time.  Take the other foot
out of the pedal.  This is usually easier to do on the road or on a 
stabilized trainer than when riding totally free on rollers.  Concentrate
on a circular stroke.  After doing this every day for a few minutes,
your pedal stroke will improve.

The best thing I have found for riding out of the saddle is to really
concentrate on pulling up in back.  You can feel the increased pressure
on the top and back of the shoe when you pull up.  It is amazing how
much more power can be generated this way.  It is even possible to 
practice out of the saddle riding on rollers, but I have not been able
to do a full-out sprint on my rollers.  If you want inspiration, watch
the video about the life of E. Merckxx (Le course en Tete?).  There are
sequences of him riding rollers in his garage.

I was in a sports shop yesterday and discovered a new type of 'power bar'
that's just been imported from the states. It's called a "Performance Bar"
and comes in a silver foil wrapper (easier to open than a power bar too).
It has a rice base, with all the usual minerals,  high carbo content,  and
15mg of amino acids as well.  They sell for $NZ2.50, as opposed to Power
Bars at $NZ3.75,  so seem a good deal.  I had one on a long ride this 
morning and I had a good,  long and hard ride on that and an electrolyte
drink. I say 'I' had a good ride as I don't want to give the bar all the 
credit.
Does anyone on the net know about these "Performance Bars"?  I'd appreciate
some user's-knowledge on them...

Thanks in advance,

bout a month ago, during a medium length (60ish km) hard ride, I managed to do
something to my right knee. It feels fine under all circumstances, *except*
when I'm pushing on a downstroke. Then I feel a chronic ache, under my kneecap.
Nothing else I do (running, walking, poking at it with my fingers) seems to
hurt it.

Saw a doctor, he said I'd bruised the cartilage under my kneecap. Since
Acartilage doesn't have a very good blood supply, it doesn't tend to heal very
fast. He prescribed complete rest from cycling for six weeks (gasp!), and then
gradually build up strength, keep spinning and don't overdo it. He said if I
didn't do this, it wouldn't heal for several months, perhaps never if I keep
cycling.

Waah!

Can any knee gurus give me a second opinion, or some advice generally? I'm not
keen on being in dry dock for a month and a half.
