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: http://thorncyclesforum.co.uk/index....59139#msg59139 Andre Jute 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. |

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? - Frank Krygowski |

Better Braking?

Slocomb wrote: Own Data? You mean like your assertions that a cheap Chinese flashlight is a perfect bicycle head light? ... I have taken Steven's word at the effectiveness of "cheap Chinese flashlights as bicycle lights" and he was completely 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? -- - Frank Krygowski 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. 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. - Frank Krygowski |
