If collision occurs and the chain goes off, the sharp slicer disc at the front can slice the person bottom wide open. Dangerous. There are a lot more dangers in a recumbent than that unlikely scenario. |

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. |

I googled some and still don't get what leg suck is. What is it? Unrelated (I forgot or never knew): are recumbents faster downhill than uprights? |

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. The visibility issue is minor to non-existent; I consistently get more room from motor vehicles when riding a recumbent. Except for a few lowracers, visibility and being seen is a non-issue (unless you believe driving a normal sedan is also unsafe). Leg-suck is not an issue with proper foot retention. We could also make a list of dangers only inherent to uprights, most of which involve going over the bars and landing on one's head from various causes. -- Tom Sherman - 42.435731,-83.985007 LOCAL CACTUS EATS CYCLIST - datakoll |

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. |
