Voiding the warranty -- Dyno Redux
After breaking my old Cannondale Disc CX bike, I got a replacement frame CAADX with a CF fork and aluminum steerer -- with a nice threaded hole in the back of the crown for a fender bolt but no hole in the front for my Luxos B dyno mood light. So, I was going to get a bar mount, but I like the light on the crown, so after doing a little research and while hallucinating on pain meds (from my little accident a week ago that netted a rib fracture which is really painful), I drilled a hole in the crown and tapped it 5mm. The fork crown is like aluminum billet, and Cannondale just drilled and tapped it for the rear bolt (no insert), so I did the same for the front. Works great, and there is so much material that I don't have any concern about a failure.
The SPPD8/Luxos B rides again, for what it's worth (which isn't a whole lot). I forgot to charge a few times last month, so I figured I'd lug it around as a backup. I had to bend that bracket in the vice to make it closer to 90 degrees and then shortened up my FD cable just to make sure all the housings weren't whacking the light. I'm going to check the crank tomorrow since it was making a bunch of noise when I last commuted to work and throw on the winter tires. I struggled around today on a short ride and figure I'll be ready to go back to commuting on Monday. Slowly and painfully. I need to start riding so people in the elevator stop asking me why I'm not riding. I get concern from people who I basically don't even know except that I ride the elevator with them. -- Jay Beattie. |

And to continue the logic, the Urban 800 is dim at least compared to the Urban 1000; which is really dim compared to the Suburban 2500... and on and on. A motorcycle's low beam headlamp is maybe 750 lumens and is usually fine for 55 mph. It seems really weird to say you need to match that with a bike headlight. And we've talked about wet roads before; but last night, I was driving on a dark, newly paved and relatively empty four-lane state highway in the rain. For obvious optical reasons, I couldn't see my headlight beams on the wet road. If my headlights were ten times brighter, I still couldn't have seen them - but they sure would have been effective at blinding oncoming motorists. I've always suspected my hub output was low, too, but I don't have a reliable way of testing it and don't feel like doing a DYI Radio Shack project. Do you own a multimeter? Seriously! We should be able to measure the hub's output. Also, I've got an almost unused Oculus headlight. On high, it is literally brighter than the sun. I'd be happy to trade for a Luxos. -- - Frank Krygowski |

Do Yourself In? Forget about Frank's multimeter then, you might poke your lawyer hands. Does your Specialized son still know how to feed a light bulb? You could have him test some clear (12..14V) automotive .4 or .5 amps bulb with the bike stationary and giving the SP wheel a good spin. If the bulb lights up reasonably bright, the generator is fine. |

I just fixed my toaster, damn it! And the solenoid in my 1950 Westminster chime Nutone door bell. I've put a multi-meter on it, and just looking at the output voltage doesn't say much, and I was thinking about testing it across a resistor. A light bulb as an indicator doesn't tell me much either except that the light bulb doesn't get that bright. I wonder if it should get brighter. -- Jay Beattie. |

"I've always suspected my hub output was low, too" Unlikely, as others have explained. Over the built-in resistor of your DMM the hub's output might spiral up to a dizzy 7.5V. It's strictly limited by German law and the rest of us just have to put up and shut up. I know precisely how limited the German lamp system, from any maker not just BUMM, is, because I have a bicycle lamp called the Fly E (optically the same as the Cyo) from BUMM that operates off the 36V battery that drives the motor on my Kranich; in this case it is the internal electronics and the LED which limit the light output to -- wait for it -- less than that on the Cyo (BUMM claims it is the same output). You can see the output of the Fly E under ideal circumstances he http://coolmainpress.com/BICYCLINGbuildingpedelec5.html and he http://coolmainpress.com/BICYCLINGbuildingpedelec6.html For what it's worth, I still ride on my first series CYO, driven by a SON hub dynamo. I haven't seen anything from BUMM so much better that it would justify replacement. Andre Jute Perhaps I should have bought a Big Bang instead |

There is a good reason why dyno lights have not captured the market. I've always suspected my hub output was low, too, but I don't have a reliable way of testing it and don't feel like doing a DYI Radio Shack project. I have dynamo lights on three bikes, a DaHon Speed TR, a road bike, and a utility bike. They're fine for "being seen" lights, or for areas with decent street lighting. They're basically used as back-ups. This morning my wife was off to work on her bike, after a few weeks of not riding, and she hadn't charged her light, but my light with the same mount was available for her. I have this battery powered light https://www.aliexpress.com/item/32881748677.html, she has the older 1600 lumen model https://www.aliexpress.com/item/32802747811.html. I also bought several extra mounts https://www.aliexpress.com/item/32938325340.html. 1800 lumens is rarely needed and I use one of the lower power settings. One really nice feature of these lights is that instead of a strobe for a DRL, they have a "breathe mode" which is similar to what some motorcycles use for their DRL. I'd like to see future battery powered lights incorporated QC3.0 fast charging and USB-C connectors. |
