I dare you to panic brake at the limit of traction and operate the bell while the back wheel is hovering in the air. My "or similar warning device" is hands free, volume and intent self modifying dependent on the circumstance, and has been used to stop motorists on numerous occasions. It's called "voice". -- JS |

It also helps for signalling -- something I used to be ****ed off at the lycra brigade for never doing, until I realized that if they tried to signal their turns, they'd probably fall off. Also makes it much easier to get pizzas back home, since they don't like going sideways into the panniers. I rode up the Warburton Hwy for a few km the other weekend, and I am sure if I stuck my right arm out to indicate I wanted to turn right, there was a good chance I'd lose it. Yeah, I signal to move right whenever there's someone who needs to see it, and my lycra fits well, thanks. -- JS |

I dare you to panic brake at the limit of traction and operate the bell while the back wheel is hovering in the air. I have absolutely no idea why you wouldbe doing that on a shared path. Because any sensible person rides to conditions and if you can't see a ped in time to slow and ride properly on a shared path you shouldn't be on the path. If you want to ride at a speed where a panic brake of that level is something you need to do, then a shared path isn't the place for it. I do about 25km/h on clear shared paths, but if I can't see what's coming I slow, if there's a possible hazard I slow and if I want to go much faster than that then a shared path is not the place.

OOC, how does wet weather make punctures more likely? It might be explainable by water+foreign object means it is more mobile and gets flunk onto roadside by traffic, or every time it rains the gunk in the lanes gets washed to the side where bicyclist ride, or puncture repair in the wet is so miserable that you remember it longer than a repair in the dry and thus seems to happen more often. |

And because a bike/ped collision is safer for everyone than a bike/car collision, and (situation dependent) less likely besides. Though I've bounced off a few cars over the last 25+years of riding, I've only ever damaged myself landing on the road. I know of several folks who have been seriously injured while riding on bicycle tracks, including a fatality. I don't think bike paths are as safe as you believe. Especially if they are not maintained. Neighbour came a cropper on a sand patch on the M7 bikepath. It wasn't the sand that was the problem, but the steel motor vehicle strength guard rails that were the problem. Years convelessing and he'll never get back to "normal". Caveat his regular pack training ride. |

OOC, how does wet weather make punctures more likely? 1. Road gunk includes some slivers of glass. Wet tyres keep this stuff on the wheels longer than dry. 2. Wetness lubricates the rubber. Easier for glass slivers to cut through. Tom. |
