I have taken Steven's word at the effectiveness of "cheap Chinese

if you seem to think that you know anything about anything but you
have shown yourself to be a great deal heavier on opinion than knowledge of anything.

You say Mr. Scharf was completely correct when he touted cheap Chinese
flashlights as bike headlights. That was when he said dyno powered
headlights were terrible and foolish.

Problem is, Mr. Scharf is now using dyno powered headlights on his
bikes, and no longer seems to say cheap Chinese flashlights are perfect.

My first question is, was he completely correct back then? Or is he
completely correct now?

My second question regards specific details. My dyno powered LED
headlights illuminate the entire width of the lane, and simultaneously
illuminate stop signs up to a quarter mile away from me, all without
blinding oncoming riders.

The Chinese flashlight I tried could not do that, no matter how I
adjusted the tilt and the focus. It was a truly crappy headlight. What,
specifically, does yours do? What's its brand and model?

Some people use flashlights that have a narrow beam but good range.
Those lights might be okay as a be seen light but they don't light up
much of the road. Others use flashlights with adjustable focus that
spread the beams to light of more of the road. the trouble is that when
they do that they lose the range they need if riding in totally dark
conditions with no city lights.

I really like my CygoLite Rover II light as it does light up the two
lanes of the country roads around here and it does so no matter what
speed I'm riding at. Also, I can move the battery and light unit from
bike to bike easily. I do wish it had a bit more range. For that reason
I was considering getting the Centauri or Trident. Dynamo lights simply
don't meet my needs.

Cheers


I imagine it depends on what you want. I use a Planet Bike 2w when I'm
doing club rides in the evening because it's dark on my ride back home
from the start. But I'm not out in the country, only the burbs. I
don't need a lot of distance but I need something to show me the
potholes in enough time to avoid them. My guess is that a flashlight
would probably work in that case.

Then you have people riding in the rain, pitch dark, pitch dark rain
down steep declines etc. etc. etc. I seriously doubt that there's a one
for all solution.


In rallying, I seem to remember that only two brands of lamps were chosen
by all the top competitors. The dominant one was the French Cibie, used
by Porsche despite the fact that the other one, less good, was from Hella, a German firm.

I'd pay a lot if I could have the light output of that bank of big Cibie
lamps across the front of my rally Porsche on my bike...

Here you can see why I like lots of light:

And the Lord said, "Let there be light," and instead there was Busch und Muller.



We have similar potholes here but it’s usually on suburban roads with some
limited amount of light. Not the paths that you have. We have those here
but I’m not usually on them at night. Thats why it’s good to have
choices.

can A/B my dyno and my little all-in-on L&M Urban 800 every night since I
use both. The L&M produces far better light; it is one fourth the total
price of my dyno set up and suffers only in that it requires charging.

Like I’ve said before most of times that I’m riding at night it’s by
accident. The few planned times are as I described. So a dyno doesn’t do
much for me.

As for charging, it’s pretty much routine. I have to charge my phone, my
Garmin, my lights and even my watch. Pfft. Battery charge is now an
issue. A Garmin and a phone that can last for a 175km ride hS become a
thing.

Again, we all have different requirements. The fact that we all ride bikes
is way cool. Too bad we can’t avoid the bull**** here.

much for me.


Oddly, "riding at night by accident" is one of the main reasons I
settled on dyno lights. A big event for me was being on a solo tour in
Middle-Of-Nowhere Township, trying to get to a particular state park. It
was hillier than I anticipated, dinner in a restaurant took extra long,
and surprise, I had to do the last few miles in the dark.

So I pulled out the battery light I'd brought and turned it on. The
batteries got me to, oh, 3 to 5 miles from the campground. Then nothing.
On a two lane country highway.

Fortunately, traffic was light. I finished by pulling way off the side
of the road whenever a car came. I then installed a dyno on every bike.

Since then, there have been countless times I didn't plan on riding in
the dark, but had to - meetings that ran long, extra work to get done,
having too much fun to leave, etc. It's no problem. My lights are just
like those on my car. No preparation needed, just turn them on and they
work.

I can see that wouldn't be valuable for people who use their bikes
differently than I do.

As for charging, it’s pretty much routine. I have to charge my phone, my
Garmin, my lights and even my watch. Pfft. Battery charge is now an
issue. A Garmin and a phone that can last for a 175km ride hS become a

Does this bother you? Are we also going to discuss your pension and

Well I just wish that it were true that the wages were good! In reality
they're terrible. Sounds like John is following Frank into the abyss of
lies, for what reason it is unclear. Maybe he's still upset about Rivnuts.

Lies? Is it a lie that you did post that you had been elected? Is it a
lie that you did post that you and your wife had bought new cars...

It is true that I was elected.

It is a lie that my wife and I bought new cars.

I bought a new car about a year after I was elected. Is it okay to buy a
new car after 21 years? Next time I'll check with you and Frank to be
sure I'm allowed to do so.

You may want to rethink your agenda, and whatever the reason it is for
the behavior you're engaging in. It's not a good look for you.


Are you being sensitive at what John or Frank write? We have all watched
their postings that show that both are in later stages of dementia.



Pot.
Kettle.


Maybe it missed your attention that the entire subject of this thread was supposed to be about braking, not whether lights that do work do not work, Scharf's political ambitions or your ideas of propriety.

Frank, I couldn't care less what Scharf is using now. You are the moronic idiot saying that these extremely bright lights that can be directional or wide focus don't work and you're belief system really doesn't fit the 21st century.

Some people use flashlights that have a narrow beam but good range. Those lights might be okay as a be seen light but they don't light up much of the road. Others use flashlights with adjustable focus that spread the beams to light of more of the road. the trouble is that when they do that they lose the range they need if riding in totally dark conditions with no city lights.

I really like my CygoLite Rover II light as it does light up the two lanes of the country roads around here and it does so no matter what speed I'm riding at. Also, I can move the battery and light unit from bike to bike easily. I do wish it had a bit more range. For that reason I was considering getting the Centauri or Trident. Dynamo lights simply don't meet my needs.

Cheers


I think that there was a GCN video of a rim driven dynamo light and it was pretty funny because it was just like I remembered it as a kid. As you pushed the pedal down you would get a light and as you were changing over to the opposite the bike would stop from the massive resistance of a 30 watt dynamo. If Frank really uses those things he must ride a bike with a triple and a 26 to 42 gear ratio.

Others use flashlights with adjustable focus that spread the beams to light of more of the road. the trouble is that when they do that they lose the range they need if riding in totally dark conditions with no city lights.

I really like my CygoLite Rover II light as it does light up the two lanes of the country roads around here and it does so no matter what speed I'm riding at. Also, I can move the battery and light unit from bike to bike easily. I do wish it had a bit more range. For that reason I was considering getting the Centauri or Trident. Dynamo lights simply don't meet my needs.

Cheers


I think that there was a GCN video of a rim driven dynamo light and it was pretty funny because it was just like I remembered it as a kid. As you pushed the pedal down you would get a light and as you were changing over to the opposite the bike would stop from the massive resistance of a 30 watt dynamo. If Frank really uses those things he must ride a bike with a triple and a 26 to 42 gear ratio.


Funny, I rode a bike back and forth to work for a couple of years when
I was in Japan using a sidewall driven dyno and an incandescent bulb
headlight and I didn't have any problems with it.

Must be you as most people are probably using a 3 watt generator, not
a 30 watt. Oh yes, and Chris Juden, technical editor for the Cyclists
Touring Club of Britain, has noted that modern generators impose drag
equivalent to climbing less than 20 feet in a mile, and the best
impose less than six feet per mile.

I have taken Steven's word at the effectiveness of

correct. Sorry
if you seem to think that you know anything about
anything but you
have shown yourself to be a great deal heavier on
opinion than knowledge of anything.

You say Mr. Scharf was completely correct when he
touted cheap Chinese
flashlights as bike headlights. That was when he said
dyno powered
headlights were terrible and foolish.

Problem is, Mr. Scharf is now using dyno powered
headlights on his
bikes, and no longer seems to say cheap Chinese
flashlights are perfect.

My first question is, was he completely correct back
then? Or is he
completely correct now?

My second question regards specific details. My dyno
powered LED
headlights illuminate the entire width of the lane,
and simultaneously
illuminate stop signs up to a quarter mile away from
me, all without
blinding oncoming riders.

The Chinese flashlight I tried could not do that, no
matter how I
adjusted the tilt and the focus. It was a truly
crappy headlight. What,
specifically, does yours do? What's its brand and model?

I imagine it depends on what you want. I use a Planet
Bike 2w when I'm
doing club rides in the evening because it's dark on my
ride back home
from the start. But I'm not out in the country, only
the burbs. I
don't need a lot of distance but I need something to
show me the
potholes in enough time to avoid them. My guess is
that a flashlight
would probably work in that case.

Then you have people riding in the rain, pitch dark,
pitch dark rain
down steep declines etc. etc. etc. I seriously doubt
that there's a one
for all solution.

In the latter circumstances, a dyno clearly is not the
solution. In
stormy weather, fast downhill or trail, a bright battery
light is best .
. . for me, and speaking as someone who owns a dyno and
battery lights. I
can A/B my dyno and my little all-in-on L&M Urban 800
every night since I
use both. The L&M produces far better light; it is one
fourth the total
price of my dyno set up and suffers only in that it
requires charging.

Like I’ve said before most of times that I’m riding
at night it’s by
accident. The few planned times are as I described. So
a dyno doesn’t do
much for me.


Oddly, "riding at night by accident" is one of the main
reasons I settled on dyno lights. A big event for me was
being on a solo tour in Middle-Of-Nowhere Township, trying
to get to a particular state park. It was hillier than I
anticipated, dinner in a restaurant took extra long, and
surprise, I had to do the last few miles in the dark.

So I pulled out the battery light I'd brought and turned it
on. The batteries got me to, oh, 3 to 5 miles from the
campground. Then nothing. On a two lane country highway.

Fortunately, traffic was light. I finished by pulling way
off the side of the road whenever a car came. I then
installed a dyno on every bike.

Since then, there have been countless times I didn't plan on
riding in the dark, but had to - meetings that ran long,
extra work to get done, having too much fun to leave, etc.
It's no problem. My lights are just like those on my car. No
preparation needed, just turn them on and they work.

I can see that wouldn't be valuable for people who use their
bikes differently than I do.

As for charging, it’s pretty much routine. I have to
charge my phone, my
Garmin, my lights and even my watch. Pfft. Battery
charge is now an
issue. A Garmin and a phone that can last for a 175km
ride hS become a
thing.

Again, we all have different requirements. The fact that
we all ride bikes
is way cool. Too bad we can’t avoid the bull**** here.

and then a thread would look like:

Hey! I use a Gamnin!
-----
You do? So do I.
----
Wow! I use one too.
---
Doesn't everybody use a Garmin?
---
So cheap they ought to.
---
:-)


:-) And it would require so little technical thinking! Win
- win!



Well, someone could always very precisely measure some
aspect another guy cares nothing about and call it 'data'.


I don't think it's better to give no measurements, nothing but a
vague "mine is better" opinion, and say "data doesn't matter."

What do you use for lights? How well do they work for you? Why?

Tom, you have a problem confusing fantasy with reality.

Let me describe a spontaneous, unplanned dynamo test I did once. I've
described it before, but you probably wouldn't remember.

I was on a solo bike tour, heading to Bloomington IN where my kid was
soon to finish college. ("Dad, you've been talking about riding your
bike here. This is your last chance.")

I was on a nice, empty, flat four lane highway heading due west, and
feeling good because I was cranking along nicely at 20 mph despite my
full camping load.

Then I hit a bump in the pavement. After that, I heard some new noise
from my bike, and to my dismay my speed dropped about a mile per hour.

I remember checking for dragging brakes by squeezing the levers and
looking at the brake arms. Nothing. I didn't stop, but I worried
about what damage I had done that was slowing my bike. Then I realized
the bump had caused my generator to click on. I clicked it off and my
speed returned.

So at the power output needed for 20 mph, putting on the generator
slowed me to maybe 19 mph. This was with a bottom bracket generator,
but I haven't seen any real difference with a bottle dyno as I set
them up. And note, this matches Chris Juden's numbers that John
alluded to. Let me know if you need a link.

As always: Sorry for introducing real numbers into a discussion.
