new 'benter seeks advice on fully-faired rides: three wheels or two?
I'm new to 'bents, and I'm considering buying a recumbent to build up
into a velomobile for commuting. My options are to buy an ActionBent Tadpole Trike for $1400, or my LBS has a USS, MWB bent for $900. Then I'll buy a BionX power assist system and build a full fairiing for it. So my qustion is this: which bike is the better option for this? Here are my thoughts: advantages to trike: 1) don't have to design fairing to accomodate putting feet down at stops 2) lower profile disadvantages to trike: 1) wider advantages to 'bent: 1) narrower profile 2) upright means more visible? disadvantages to 'bent: 1) upright means more area for crosswinds to play with Please advise on any others. I'm especially interested in stability at speed in a fully-faired velomobiles. TIA |

Every velomobile I've seen has had slots underneath the rider's feet to allow the rider to back up. Craig Johnsen's been working on his "Pod" velomobile for a while. He's just posted new pictures: http://www.imagestation.com/album/si...?id=2128450950 2) lower profile disadvantages to trike: 1) wider Not completely true. Narrower trikes end up a little wider than a rider with fairing. However, taller trikes need to be wider for the same amount of stability. advantages to 'bent: 1) narrower profile 2) upright means more visible? disadvantages to 'bent: 1) upright means more area for crosswinds to play with Please advise on any others. I'm especially interested in stability at speed in a fully-faired velomobiles. TIA There was a stretch during last year's Race Across Oregon where John Williams, piloting his Quest velomobile, maintained 60+ mph speeds. This was down a slope, but *that* velomobile, with *that* rider, is stable enough. The entire tale can be read at: http://www.ohpv.org/albums/rao2005/index.htm Full hardshell fairings are neat and sexy, but they can be very hard to live with on a day-to-day basis. However, the Rotator Coyote: http://www.ohpv.org/albums/pir2003/r...s/neils136.htm and Mark Mueller's Coroplast-covered Greenspeed: http://www.ohpv.org/albums/pir2004/p...s/P1010072.htm (on the right) are used quite often, so it *can* be done. Personally, I wouldn't dive in without finding out what a faired bike/trike is like first. A Tour Easy with front fairing and body sock will give 90% of the improvement with 10% of the hassle, unless you really *like* building and tinkering with things. |

However, unless you are into going fast it would be best to avoid fairings and body socks altogether. They add a lot of needless complication for not much benefit, other than increasing your speed slightly. If the weather is such that you think fairings and body socks would help, then you should be advised never to go cycling when the weather is not halfway decent. After all, cycling is a recreational hobby for the vast majority of us. This is true of bike commuters too unless they are so poor they cannot afford a $250. used motor vehicle.

I say that for $250 the op would be better off making improvements to a bike or clothing for riding in not-so-good weather conditions. A $250 used MV is likely to give the op more headaches than any hpv.

What about the cold-weather & rainy-weather benefits of body socks?
I'm thinking of building a velomobile around three design constraints: I want to commute (about 20 miles, back roads & small towns), therefore, I want: -enclosure for cold weather & rain -streamlining for speed. -weatherproof luggage space for casual clothes Thanks |

That is what fools do and they invariably end up with an expensive piece of junk that makes a bloody racket and looks foolish to bystanders. You will never be as fast as you think either. And finally, the damn wind will knock you on are your ass when you least expect it if on a two wheeler. No, I would keep a bike a bike and forget about fairings and body socks, let alone full body hard enclosures. I drove cheap klunker cars for decades for just getting around town. You hardly ever see any old wrecks on the streets anymore. Everyone thinks they have to have a $20,000 car or truck when I know you can get by on just a few hundred. Now you see why I am so Great and why others are not. It is the difference between $20,000 and $200.

No, I would keep a bike a bike and forget about fairings and body socks, let alone full body hard enclosures. I would do the same thing, forget about the total enclosure thing. Just dress better for the bad weather. And on the worse days use public transit, if available. I drove cheap klunker cars for decades for just getting around town.

Sure I guess if you have the ability to do some repairs and or maint. yourself you could get by with an inexpensive used MV for use as a second vehicle. Personally I would just make lifestyle changes and remain car-free.
