There are a lot more dangers in a recumbent than that unlikely scenario.. No dangers that are not also common to uprights. Oh yeah? What about fire, then? None of my upright bikes ever had HALF the risk of forest fire that this recumbent has. |

Dense urban traffic situations are very dangerous for recumbents. It is best to avoid these conditions altogether unless you have a shoulder to ride on.

Recumbents have some inherent dangers that don't exist in diamond frame (or other upright) bicycles. There are visibility issues, both seeing and being seen. There's the danger of leg suck. Some recumbents do not have leg suck problems. As for beeing seen and see, just get a model where you sit high. |

While i live in Copenhagen and most roads does have a seperate bike path along the side, there are roads that does not have a bike path. I see fine and i believe i am seen. |

However, because serious accidents are so rare, it is difficult to quantify the difference in safety between an upright which DOES have very good visibility and a recumbent which has reduced visibility AND reduced ability of the recumbent rider to see forward. My cruzbike freerider has not reduced my ability to see forward. I have been in 1 accident where a car turned right infront of me. I was going downhill and was doing 46,4 km/h shortly before i slammed into the side of the car. I was even clipped into my pedals. I did manage to brake a little, but i was unharmed. My bike got a little dent at the left pedal arm base. The car got a scratch along the side. I avoided an accident hitting a small kid that ran infront of me by applying the brakes, removing my feet from the pedals, sving them down to the ground when i was slow enough, and then the bike turned around the front wheel, lifting the rear wheel and the bike making the seat follow my back as i stood up. All in a crontolled manner. On an upright bike i have fallen sidewards and got a concusion. A friend did the same and broke the colary? bone that holds the arm. I believe that recumbents are more safe than uprights. |

Well speaking for Jeff Grippe,
I was on a Tricruiser which is quite a high trike. I had a very bright blinky light and it wasn't dark. I was right in the middle of the lane and not off to the side as there was no shoulder at that point. The car that hit me wasn't paying attention. It was a combination of bad judgement and high vulnerability. In most places, cyclists aren't safe. Car drivers aren't trained to share the road. There are far too many car drivers and far too few cyclists. When the ratio is a bit more balanced then riding will be safer. It has nothing to do with the design of the bike and everything to do with the design of motorists. Jeff "Phil W Lee" phil(at)lee-family(dot)me(dot)uk wrote in message ...

However, because serious accidents are so rare, it is difficult to quantify the difference in safety between an upright which DOES have very good visibility and a recumbent which has reduced visibility AND reduced ability of the recumbent rider to see forward. This is hard to quantify, but the recumbent has a high "what the heck is that factor" which attracts more attention. Agreed but that is AFTER it has been spotted. But the problem is less often being seen than being noticed. Motorcycle sidecar outfits get a similar benefit. |
