One of them would never be able to keep up with our group and the other could on regular bikes. With recumbents they keep up with the group without problems. One of them takes pulls at 25+ mile per hour without braking a sweat. On flats, recumbents transform average cyclists into animals. The lower the recumbents the faster these guys become. One has a very low racing recumbents and he built an aero contraption in the back. He goes really fast in that apparatus and because he is very low, it is hard to draft him. He makes a great training partner. It's sort of like motor pacing. On hills, he slows down quite a bit though. It is not just the weight. His racing recumbent is not that heavy. For the sake of argument, let us assume that that a particular recumbent is 20% faster on the flats and equal on the climbs to the group members' uprights. If the recumbent rider is just the equal of the group on the flats, that means he is a considerably weaker rider, so it is no wonder he gets dropped on the hills. What is being demonstrated is not the poor climbing ability of the recumbent (which is typically the false conclusion made by the upright riders), but rather its performance advantage on flatter terrain. "For the sake of argument"..boy, that speaks volumes......... There is no recumbent that is 20% faster than an upright on the flats everything else being equal. At best, it is possible that a recumbent will be only ever so slightly faster than an upright on the flats, but even that is debatable. sWhat is not debatable is how freaking slow they are climbing hills, even small hills. Case closed as far as I am concerned. Regards, Ed Dolan the Great - Minnesota aka Saint Edward the Great - Order of the Perpetual Sorrows - Minnesota Recumbents are surprisingly faster on flats. There was an average cyclist that got a recumbent and he is always taking pulls at the front. He can easily motor at 25+ miles an hour. It is tough to draft him cause he offers little wind protection. On hills this dude is slow, but not amazingly slower. There is a group of us that rides fairly fast. We go out every weekend and go for 50-70 miles and we average over 20 miles an hour with 27-29 mile efforts along the way. There are more leisurely groups that ride on weekends. A few of the guys in the leisure group got recumbents. On occasions they cross groups and ride with us. The can hang on notably well. In the past, they wouldn't have been able to do so. For fast pack riding, there are some disadvantages to recumbents over uprights. Uprights are more maneuverable and can accelerate faster. also when we get in a rotating paceline, recumbents cannot rotate. They cannot sprint. However, once they get going, they can motor fast. The guys that ride on recumbents usually stay in the back and go to the front to take pulls. On sprints and attacks, they may get dropped, however, when the pack slows down, they can quickly get back. I have never ridden a recumbent nor I intend to for now. I like my bikes way too much. However, they are useful and can move very fast, especially if you are riding distance alone. I think that recumbents are enjoyable and serve a purpose. They are not better or worse than upright bikes. It's kind of comparing a road bike and an mtb. The road bike will do better on the road and the mtb will do better off road. having recumbents competing against road bikes will have varied results depending on the course that you set, the conditions, etc. Who cares. Ride what you like. Andres |

I'd say that the unfaired recumbent hour record is pretty darn remarkable. Did any noteworthy rider do it? Also, remember that there are two different UCI hour records: one for traditional bikes at slighly over 50 kph and the "absolute" record at slightly over 56 kph. Both were unfaired, but the traditional bike requires use of only drop handlebars and a minimum of 24 spoked, regular depth rims, and no aero helmet, perhaps no aero shoe covers either. The absolute record allowed disk wheels, aero handlebars, and aero helmets. |

I'll make you a bet then: simultaenous hour record time trials for unfaired UCI bikes and for fully faired recumbents. During a hurricane. |

You /can/ "dance on the pedals" but the suspension forks will bounce, wasting a lot of your energy. The only time I've ridden a Moulton is since I took to spinning anyway, but a recentish test of the AM Vitesse in "Cycle" (CTC magazine) confirmed they're not really very good ridden hard out of the saddle. Which wouldn't bother me now, but would have annoyed me enormously 15 years ago! Pete. Dear Peter, Thanks--I forgot about the Moulton fore and aft suspension. Cheers, Carl Fogel |

The only (recognized) hour record that looks to possibly be an unfaired recumbent was set in 1938 at 31.4 mph. Quite a remarkable time if that was the case. Help me out here a little bit. |
