Like it does on cars. No super-expensive boutiques stuff, regular affordable gear, just like on cars or motorcycles. I use such trails regularly also for commutes and pretty soon it'll be dark when I get back. So right now I sometimes have three different lighting systems front an back in order to be able to switch to the next after one fails. http://goo.gl/IPoGVq Those links don't work here, produce just a blank page. -- Regards, Joerg http://www.analogconsultants.com/ |

No, definitely not, then you'd land on a site you did not click on. But some of the more intrusive scripts get blocked. There is usually some content, sometimes not. You basically see that some script wants to connect to a server that my firewall considers suspect and then it all ends right there. Sites I need for my jobs such as Digikey or McMaster and sites for biking such as PricePoint do not have such issues. Nashbar .. different story, so I buy at PricePoint. -- Regards, Joerg http://www.analogconsultants.com/ |

It does a great job of illuminating the road, with a nice even beam, and I can see it illuminating stop signs nearly a quarter mile away. The setup isn't cheap. I paid about $65 for the hub, and the headlight was a $100 Christmas gift. (I built up the wheel myself.) But I don't expect to have to replace the setup for the next ten years. To me, it's worth the expense. Certainly, it would be cheaper if it were standard equipment on every bike; but we have to face the facts, that most people in westernized countries use bikes as daytime toys. They wouldn't want to spend the money for a headlight they'd seldom or never use. While this is a road bike, last week I used it after dark to inspect some work we'd recently done in our local forest preserve. I don't know whether it would work on a wooded off-road trail at 25 mph, but it allowed me to do fine on the single track trails I was riding at much lower speed. - Frank Krygowski |

It would be possible but difficult on my mountain bike because it has a serious disc brake up front. I'd be ok with a central Li-Ion battery if some company made a better holder than those flimsy Velcro thingies. The lights I've seen were all plastic and/or on skinny brackets, those on the Lumotec lights would never survive. I need something that will survive even if a rock the size of a fist smacks to it. Happens a lot. Like Tuesday, barreled down a trail to get home, front wheel squished off a rock that size, it ricocheted from somewhere ... *KANGGG* ... smack-dab between my right foot and crank. I stopped and it was still cradled there. Took a chunk out of the crank and my shoe. Earlier this summer one ricocheted off and crashed into the handlebar. Then there's the rocks kicked up by other riders. And the occasional thick Manzanita branch. -- Regards, Joerg http://www.analogconsultants.com/ |

Maybe take a look here... http://www.sp-dynamo.com/8Xseriesdynamo%20hub.html When I win the lottery :-) I think Schmidt and Sons in Germany makes something like this but then you be looking at 100 Euros plus labor. I really don't like to do spokes. Have done it but hated it. I'd rather have a central battery where you can get a ton of capacity at same weight. Then the bike can power lights and other gear even at standstill, like during breaks. For example, when a friend discovered a cave we were able to take the light off my bike and crawl in.

On a mountain bike there is really nothing you could fasten it do, you'd have to buy or build a clamp bracket. This kind of U-shape carrier will not hold up, it'll get bent real soon. The enclosure itself needs to be metal, aircraft aluminum or something similar. I've even broken ABS. -- Regards, Joerg http://www.analogconsultants.com/ |
