The Gerry Attrick bike: Mixte or Bent?

In considering ordering a custom stainless frame to see me out, I thought of the top tube and the obstruction it might be in time, when after the nth hip replacement I can no longer swing my leg over the saddle. Or of course, leglifting might be become non-PC and outlawed, and bicyclists will be hunted through the streets with smokers. I looked into recumbents and even bought one to try and hated it; it lasted a week before I sold it on. It reminded me of driving to work in the city in a Porsche, eyeing the nuts holding on bus wheels --from below the hub. For me a recumbent seemed too much like assisted suicide by truck. Then I thought of the opa/oma Dutch bikes, which are low stepthrough styles for ladies of a certain age and uncertain future. That was just too depressing. (Chalo is looking for one...) Then a compromise solution struck me: the Mixte. the style has a downtube but the seattube is angled down parallel, or almost, with the downtube. Or in the classic Mixte application there are two thin tubes from the head tube parallel or almost to the down tube and running all the way back past the sides of the seat tube to the junction of the chain- and seat-stays. You can still lift your foot through the gap reasonably easily and the bike will be reasonably stiff, or at least stiffer than those U shaped things... Of course there is no point in ordering a custom bike and having it fillet-brazed. It has to be lugged, and preferably with fancy lugs which can be painted a contrasting colour or at least lined with my house colours of maroon and yellow. The difficulty of finding stainless lugs for a Mixte is holding up the project. The other difficulties that drive people to bents are easily solved: a seat rather than a saddle, geometry to put your feet on the ground (if you/re too old for legover, you're old enough to want to sit upright, right?), an automatic gearbox to keep pedalling effort in the most efficient range, front suspension to keep the inequalities of the road out of arthritic fingers (in fact the only arthritis I have was caused by a bike falling on my little finger a few months ago; when I catch up on the driver of the car that caused the accident he'll be in pain for very long time), a suspended seatpost to keep piles comfortable, and so on. I've even got adaptive front suspension -- electronically set to hard when you set off, softer riding at speed on the level, hard to conserve energy when pedalling uphill -- in the Shimano Cyber Nexus groupset I bought for this Gerry Attrick bike. Of course, planning such a bike keeps one young, thus defeating or at least delaying the purpose. Andre, Please take a look at the crank forward (CF) bicycle RANS offers and tell us what you think: http://www.ransbikes.com/. These CF bicycles have something more like a real seat than a conventional upright bicycle saddle, a geometry that allows the rider to put both feet on the ground when seated, and a step-over height mid-way between a diamond frame and a woman's step-through city bicycle. -- Tom Sherman - Holstein-Friesland Bovinia "And never forget, life ultimately makes failures of all people." - A.

I saw those bikes the other day when someone posted the same URL and for me they raised more questions than answers, and a second look doesn't bring me any closer to an opinion except that they appear pricey considering that for under a grand in Europe you can buy a really good bike from a distinguished maker. But that's more of a delaying tactic than a useful observation: if the RANS bikes truly have something special, the price is irrelevant. -- Andre Jute -- Tom Sherman - Holstein-Friesland Bovinia "And never forget, life ultimately makes failures of all people." - A.

Be aware that the RANS CF bicycles are made in Hays, Kansas by welders who are generally also certified to do aerospace work (RANS also builds airplanes). They also have some parts that are not "off the shelf". Both these factors raise prices. In the recumbent market, RANS would be considered a "distinguished" manufacturer. -- Tom Sherman - Holstein-Friesland Bovinia "And never forget, life ultimately makes failures of all people." - A.

Do you have any first hand experience with these? They look to be an interesting design and I see they (RANS) are bringing a new frame for taller riders to market. |

No, but I am tempted to try one of the RANS CF bicycles. They might well be the best solution for the rider who does not find either a traditional road bicycle or a recumbent to fit his/her needs that well. The CF will likely be slower than the road bicycle but considerably more comfortable. The recumbent offers comfort and speed advantages over the CF bicycle, but is less user friendly in several ways. -- Tom Sherman - Holstein-Friesland Bovinia "And never forget, life ultimately makes failures of all people." - A.

No, but I am tempted to try one of the RANS CF bicycles. If you do, I would be interested in your impressions. They might well be the best solution for the rider who does not find either a traditional road bicycle or a recumbent to fit his/her needs that well. I'm looking at them from the "something different" perspective. I've five DF bikes in my mini-fleet and don't see what another would bring to the party. The CF design is just enough "different" to be of interrest. The CF will likely be slower than the road bicycle but considerably more comfortable. Hmmm.....I do not find my "road bicycles" at all uncomfortable. And I wouldn't expect a CF to be "fast", I have others for that purpose. The recumbent offers comfort and speed advantages over the CF bicycle, but is less user friendly in several ways. Recumbents are totally out of the question for me. Sorry. |

For what it's worth, opafietsen have top tubes. They have higher standover than any up-to-date bike frame of equivalent size, in fact. http://www.workcycles.com/workbike/b...a-bicycle.html Here's the size that interests me: http://www.workcycles.com/workbike/b...e-gt-70cm.html You might have a point, though, about the depressing nature of traditional Dutch bikes: http://www.flickr.com/photos/cleverchimp/1589947928 Chalo |

Or of course, leglifting might be become non-PC and outlawed, and bicyclists will be hunted through the streets with smokers. Plenty of high performance bikes with low stepovers. My interest isn't in high performance bikes even now that I'm whole and and hale and hearty. One suspects that with advancing years one's interest will focus even more closely on comfort and utility. The Moulton springs to mind as an obvious one, look at http://www.tsr.uk.com/ for the cheaper ones, http://www.alexmoulton.co.uk/ for the more expensive (the Bridgedale isn't cheap, but ,much cheaper than the others listed there). I spoke to Dr Moulton once for a book of mine, unfortunately not about his own work (my editor though him "too rarified") but briefly to get something quotable about Sir Alec Issigonnis. Moulton is one of my heroes, a true lateral thinker of stupendous versatility. But most of his bikes I wouldn't spend my own money on; I have too much spaceframe experience to like bunches of little tubes -- call it a personal prejudice, if you like. I'm a big beam man. Your library has or can get a copy of my book Designing and Constructing Special Cars; check out the substantial chasses of my own cars. Furthermore, I live in a country where the roads are (were until recently, actually) so bad that a bicyclist on the way home from the pub falling into a pothole and drowning was a matter of national political outrage rather than a cruel joke. Small wheels just won't do. Also gives you a good road-going suspension to help with those other joint grumbles. I looked into recumbents and even bought one to try and hated it; it lasted a week before I sold it on. It reminded me of driving to work in the city in a Porsche, eyeing the nuts holding on bus wheels --from below the hub. For me a recumbent seemed too much like assisted suicide by truck. "Recumbents" covers a lot of bases: mine has the seat height at the same height as a conventional car so I'm not eyeing wheel nuts face to face, so if being too low was a problem, maybe look at a higher one... Recumbents have other serious problems. I was never a bike racer, so I never learned to pull on the upstroke and I'm not planning on learning now. Cleats and shoecages and straps are a nuisance I don't need. I get off my bike and walk up hills or into the library, so I just wear fairly stiffsoled street shoes. The thing I learned about recumbents in those half-dozen rides is encapsulated in something truly shiver- making that Tom Sherman said when he mentioned riders "trained" for riding recumbents. I don't fancy retraining for cycling, an activity I consider should be fun rather than a socially acceptable form of sado- masochism. Thanks for sharing your expertise, Pete. Pete.
