hello everyone I've been researching delta and tadpoles for some time now, and I'll admit I'm leaning toward the tadpole concept. I realize that even the manufacturing sites say some technique is involved, but I don't see the big deal, it's technique, not rare talent. I'm 6'6" with an "x-seam" of nearly 50", if I did it right(a 36" inseam). There's no one in my area that sell tadpoles or any kind of `bent rider for that matter and the more I research the more I'm itchin' to try one. I'm in the Albany, NY area the nearest retailer is 2½ hours out. I'm not completely in the dark on cycling I've owned racers and mountain bikes since I can remember and I'm quickly becoming a fan. On another note there will be a meet in western NY in August. http://www.bentrideronline.com/bentride/nyevent.htm I'm hoping that will quell my curiosity. Thanks for reading. I'm hoping to meet some people out there who can teach me a thing or 2. db.

Ed is nothing but a troll....something I would never look at or reply to twice. He's an A-hole of the highest order but aren't all trolls? Just glad that I don't run into many a-holes like Ed in the real world. When I do I just shoot them through the head and keep on going. And you've got that right about life being too short.

Here is the atypical ARBR cyclist. He is just barely literate and his only emotion is one of wanting to commit violence. He is what is known as a redneck and it is a separate culture in the US of A to be found mainly in the South, in some rural areas and in the Inner City.

"Get a helmet type rear view mirror and bolt it to your helmet if necessary. Those rear view mirrors that attach to the trike frame are worthless." Guess I wasn't specific enough about the mirrors.....2 mirrors = 1 on the bike and 1 on my helmet. "Trikes are NEVER faster than a road bike".....You are wrong about that statement (I'm sure not the first time or the last time, for that matter). You're another know-it-all but actually know nothing at all.

I live in White Plains which is not close to you at all. I traveled to yland to Mt. Airy Bikes in order to test ride trikes. They have a large inventory and if you go when they are not busy they will set them up for you and send you out on a mile long test ride. There is also a shop in southern NJ and one in PA but I haven't spoken with either one about their test ride policy or stock situation. If you can plan a trip to the DC area either for business or as a tourist (I have friends down there and my son had a school trip so I managed to dovetail it all together) then I think Mt. Airy is your best bet. Their URL is www.bike123.com Best of luck.

But what does aerodynamics have to do with going > UP a hill? Since when does one only ride up hills? What goes up must come down as they say. That said... The main advantage wedgies have up hills is weight ('bents are generally more complex thus higher weight...although the smaller wheels can save some), but comparing a modern wedgie to a modern SWB 'bent the weight advantage isn't huge (significant, but not overwhelming...a few pounds at most). For a trike however, it gets very hard to not add significant weight as well as rolling and drive train resistance (but again, smaller wheels can help and with 3 of them you don't need the gyroscopic effect for stability). Some will try and clame a leverage/torque advantage for hills, but against a closed position SWB 'bent like a P-38 that argument really doesn't hold well. Add a high BB and 'bents gain an endurance advantage as the rider's legs don't need to fight gravity as they do on a wedgie. Add to this that the pull stroke is much easier to get good power from on a high BB design. Oh yah...and a high BB 'bent can power around the fastest of turns w/o any fear of ever dropping a peddle into the road. Add it all up and "the ONLY advantage that a" wedgie has over a 'bent is going up very steep hills (with low wind). Moderate hills they are about even, while down hill and flats the 'bent will just destroy the wedgie. If you add much of any headwind and the 'bent starts looking very good even on steep hills. Oh yah, there's also the advantages of no neck/back ache, still being able to spawn children some day, and of course a nice tight r-butt. :-D -Zenin

If the gyroscopic effects of bicycle wheels had /any/ significant effect on the ability of one to balance a bicycle, then contriving a pair of wheels that were off the ground, rotating in the opposite direction to the road wheels, would result in an unridable machine. David Jones did precisely this when trying to build an unridable bicycle. It was easily ridable.

A) Jones only countered the front wheel, not both wheels. -Which seems an odd oversight, but he's ster then I and must have had his reasons. The fact is however, he did not do "precisely" what you claim he did. Pick your words more carefully if you don't intend to actually read the works you site. B) The bike would collapse instantly when goast ridden. C) "Hands free" riding was much more difficult. Quote: "URB I is not an easy bicycle to ride 'hands free' even with the front wheel static; it somehow lacks balance and responsiveness. In the disrotatory mode it was almost impossible and invited continual disaster, but it could, just, be done." D) Only slow speed stability was tested. E) Jones concluded that the gyroscopic effect was a significant factor in the inherent stability of a bicycle (albeit not the whole story): "This test completed the ingredients for a more complete theory of the bicycle. In addition to the rider's skill and the gyroscopic forces, there are, acting on the front wheel, the center-of-gravity lowering torque (figure 6) and castoring forces; the heavier the bicycle's load the more important these become." http://ist-socrates.berkeley.edu/~fajans/Teaching/MoreBikeFiles/JonesBikeBW.pdf Perhaps actually reading the work you site would do more to make you appear intelligent then simply misusing Latin abbreviations. -Zenin

THe equations for the effect of moment of inertia of the wheels are in my text. You have an interesting observation of Jones' experiment. I had not thought of the lack of a counter rotating rear wheel on his urb. That is a great idea for a future experiment. I have found that wheel inertia is a small effect and is not nearly as important as trail. The problem of early recumbents was that we had a myth that bikes should have an 18 degree castor angle. This is exactly wrong. As the wheel gets smaller and lighter, it has less inertia. Smaller wheels need more trail not less. Of course the side ward friction force on the front wheel is what makes bikes handle and the friction force on both wheels make the bike ride able. If you think that wheel inertia (gyroscopic) is important, ride you bike on the ice and see how important the side ward friction force really is. I must add the caveat that tiller/stem was not addressed in my earlier theory. I knew it was important but didn't have a clue until I had a long set of emails with k Stonich. The theory now includes tiller/stem. Zenin wrote: > > A) Jones only countered the front wheel, not both wheels. -Which seems > an odd oversight, but he's ster then I and must have had his > reasons.

How do you explain track standing on a normal bike? I might add that there are a lot of people who can do a reasonable track stand. Balancing whilst rolling slowly has nothing to with gyroscopic precession either, it's all about keeping the wheels below your centre of gravity.

Aye, but it's not nearly as easy as a bike in motion, now is it? I clearly noted it's possible, just considerably more difficult. It's more difficult because it's less stable. With particular reguard to ride stability, the gyroscope effect is what causes a bike to naturally remain upright while in motion. That natual tendency to remain upright is what gives a bike stability. > Balancing whilst rolling slowly has nothing to with gyroscopic precession > either, it's all about keeping the wheels below your centre of gravity. If this is the case, explain how a bike can goast ride itself trivially, but getting a bike to not fall over while not in motion is basically impossible. -Zenin

Obviously you've never ridden in the pacific north west. :-) 40+ mph winds are not uncommon along the coast, as are hills (at least in Washington...Oregon is much flatter). Most sane riders tour north to south to try and ride with the prevailing winds, because riding into them has been known to be strong enough to stop a bike descending even high grades (although those reports were made by wedgie riders :-) The importance of aerodynamics depends upon the windspeed, not so much the land speed or the grade. While typically your windspeed will be low enough to not matter when you ride slower (as happends when going up a steep hill), that is not always the case (the pacific north west coast again being a prime example). > That is all about weight and gravity. I am not talking about roller > coaster type of hills, but real hills where you end up cussing at them. I mentioned this in my other post, but again for me I ride bicycles to go fast....if I wanted to go slow I'd take up jogging. Over the average of road conditions a decent 'bent will easily out perform a decent wedgie. For me at least, throwing away a huge speed advantage over most road conditions (down + flat + moderate hills) so that I can gain a small advantage over a tiny subset of conditions (hella steep hills) makes no sense to me. Not only will it not get me from point A to point B any faster, it's optimizing for the part of the ride I hate (the slow part). Being able to go 6mph instead of 5mph up a hill doesn't turn my crank even if it is 20% faster. Being able to go 60mph instead of 50mph does. You've stated clearly you dislike (or are afraid of) going fast, so of course for you it makes perfectly reasonable sense to optimize for the slowest subset of conditions. To me that would be silly, but again I like to go fast. > >> did I not already sya somthign about how everybody looks good going > >> DOWN a hill, even kids on total klunkers?

That is not in dispute, never was. Most recumbents are optimized for other considerations such as comfort, ease of slow speed control, weight barring (for touring use), etc. The same is true for wedgies (most wedgies sold are not performance designed bikes). And just as true for wedgies, some 'bent designs are designed for performance. When you pit a performance built wedgie against a performance built 'bent (SWB, closed position, high BB, low CG), the 'bent wins handedly (given equal motors of course) on all counts save for very steep hills. Your claims have not been, "Most 'bents don't take hills well" or even "the average 'bent is slower then the average wedgie", your claims have been "No 'bent will ever match the raw, unbridled power of a wedgie!!!!

Jogging is way too hard on the anatomy. It is best to just walk at a normal pace for a couple of hours a day. That will keep you fit and clear the mind as well.

Yes, having to go too slow on any bike is a drag and no fun at all. But I remember my bike tour of the Colorado mountains. A recumbent would not have worked for me in that terrain. Rolling hills are not that bad on a recumbent, but still they wear you down. Cycling really comes into it's own on the flats. It is just too hard to go up hills on a recumbent. > You've stated clearly you dislike (or are afraid of) going fast, so of > course for you it makes perfectly reasonable sense to optimize for the > slowest subset of conditions.

I have cycled in many other areas of the country which are not nearly so flat as the Upper Midwest. Having to cross a major mountain range on a recumbent is my idea having died and gone to hell. It is not easy on an upright either, but it is doable. Frankly, it is not doable on a recumbent. >>>> Recumbnets will gradually fall behind uprights because of hills.

I have noted how recumbents can pass uprights going down hills, but that is about it. Recumbents will always fall behind uprights going up hills. And I do not believe recumbents are overall faster than uprights. I am only interested in real world situations, not racing events. >>> At the end of the day you still end up with a minor advantage for >>> wedgies going up, and a huge advantage for 'bents going down and on >>> flats.

And aerodynamics do not come into play going uphill. I will admit I have seen recumbents more than keep up with uprights on the flats. It is possible that recumbents could actually be faster than uprights on the flats. I remain unsure about this. But hills ruin it for recumbents as far as I am concerned.

No worse then standing off the seat of a wedgie. My knees (along with my back and neck) always hurt badly after riding a wedgie for a few hours. On my P-38 I can do 8-10 hours daily without any such pain. -Well, I could when I was in training for touring...I'm not in nearly the shape needed for rides that long right now. But the point is if the 'bent is any harder on my knees then the wedgie, my knees sure as hell never told me about it. >>> Add a high BB and 'bents gain an endurance advantage as the rider's >>> legs don't need to fight gravity as they do on a wedgie.

I must say after being away from this group for a couple years, it's nice to know the comedy hasn't been forgotten. Thanks. :-) >>> Oh yah...and a high BB 'bent can power around the fastest of turns >>> w/o any fear of ever dropping a peddle into the road. > > I never feel safe making fast turns on any kind of a recumbent.

All you have to do is fall off your recumbent just once in a turn and land on your tail bone and you will become a true believer. Recumbents are far more tricky than uprights. I have ridden many thousands of miles on various recumbents and I never trust any of them entirely. > Myself I know my P-38 well enough to take high-lean turns even at > speeds > over 60mph while still pumping, without fear. -When I was touring I'd > frequently do such speeds down mountains while pulling a Bob trailer > with 60lbs of camping gear...still as rock steady as a racing > motorcycle.

That is why you can do a track stand on an upright and you can't do it on a recumbent. However, regardless of center of gravity, you are riding very dangerously. 60 mph is not a bike speed. Anything over about 30 mph does not feel safe to me, regardless of the design of the recumbent. >>>> Add it all up and "the ONLY advantage that a" wedgie has over a >>>> 'bent >>>> is going up very steep hills (with low wind).

I believe uprights are quite superior to recumbents when it comes to climbing hills and that nothing can make up for it. The only sensible thing to do is to stay out of the mountains if you are riding a recumbent. Ed Dolan - Minnesota

I see what you're saying here now. The position allows a rider even greater resistance then is available from simple gravity on a wedgie. It then falls upon the rider to judge how much pressure their body can take. That said, the body can take a hell of a lot. Weight lifters for instance put massively more stress on their knees with the exact same geometry when doing standing lifts. If a 200lb guy can pickup two hundred pounds, to match that same stress to his knees pushing on a 'bent he'd have to push with 400 lbs of force. I know I can't generate that kind of force if I tried, much less while holding a decent cadence. Besides, it's mostly a mute argument for anyone riding with clips on a 'bent as you're pulling nearly in equilibrium with pushing, generating no substantial force against the seat. -FYI, on a 'bent it's generally much easier to take full advantage of clips then on a wedgie. Woops, there's another advantage to the 'bent... :-D >> My knees (along with my back and neck) always hurt badly after riding >> a wedgie for a few hours.

It's really odd for you to say this, because quite frankly the arguments you seem to make are only understandable if they came from someone with little to no real experience riding 'bents? If I might ask, what 'bents do you own/ride and how long have you been riding? Personally I ride a P-38 with a small Zipper fairing. I've rode it for nearly a decade now. I've ridden a few different LWB bikes as well, but never owned one. My only wedgie left in the stable is a mountain bike. >> But the point is if the 'bent is any harder on my knees then the >> wedgie, my knees sure as hell never told me about it. > > As long as you don't push too hard your knees should be fine. But the > potential is there for severe damage. Just getting in the seat of any bicycle has potential for severe damage. Avoiding this "danger" seems like a no brainer: "Hey, my knees feel like they are going to explode! Maybe I should gear down and raise my cadence a bit...and/or buy some clips and pull as hard as I push." Recumbents are pretty numerous...if what you claim is really even the slightest bit a practical possibility, surely there should be at least some anecdotal evidence of people blowing out their knees this way? Got any links to share? I've not heard any stories of this ever happening? I've heard and experienced recumbent butt, but never recumbent knee. >>>>> Add a high BB and 'bents gain an endurance advantage as the rider's >>>>> legs don't need to fight gravity as they do on a wedgie.

By this logic of yours, "the whole concept about hills working either for you or against you is also very funny". Here's a test: Run 100 yards flat. Now go find a stair case that is 50 yards long and run up and back down it. Let me know which 100 yard dash took more effort. >>>>> Oh yah...and a high BB 'bent can power around the fastest of turns >>>>> w/o any fear of ever dropping a peddle into the road. >>> >>> I never feel safe making fast turns on any kind of a recumbent. >> >> If you're that unsteady on a 'bent that's your problem.

Recumbents are far > more tricky than uprights. I have ridden many thousands of miles on > various recumbents and I never trust any of them entirely. It probably depends on the 'bent, but on my P-38 dropping the bike is intrinsically a hell of a lot less traumatic then a wedgie. In particular there isn't far to "fall" (I quote "fall" because it's more like "sit down" in practice)... Dropping a P-38 in a turn means "falling" some 12" at most. It's not the fall that hurts, it's the road rash, which is the same for wedgie or 'bent. Wedgie bikes in stark contrast nearly guarantee when the rider falls they will fall far, hard, and uncontrolled. Every 'bent fall I've had or seen has been some form of "sitting down on the pavement". I can't remember anyone ever breaking anything. Wedgie falls however...man, even the smallest of falls is hard for me to watch and I hang around with skaters. And it still amazes me these claims you make as to actually being a 'bent rider...your statements just don't have the ring of experience. >> Myself I know my P-38 well enough to take high-lean turns even at >> speeds over 60mph while still pumping, without fear. -When I was >> touring I'd frequently do such speeds down mountains while pulling a >> Bob trailer with 60lbs of camping gear...still as rock steady as a >> racing motorcycle.

You're confusing the effects of gyroscope with center of gravity. Or you're just trying to be funny.

Anything over about 30 mph does not feel safe > to me, regardless of the design of the recumbent. It may not feel safe to you, but frankly that's your problem. It does however, make some sense of your statements; If you're riding the brakes down a hill to keep from going over 30mph, of course you're never going to make up any time you might have lost going up. It sounds to me like you're afraid generally to go fast, so you're trying to make believe the entire sport of bicycling is done at slow, tedious speeds (ie, all uphill, riding the brakes down). For me I like bicycling because I like to go fast. If I wanted to go slow I'd take up jogging. And I'm not sure what clunker you ride, but my bike rides like it's on rails at 50+mph. My only problem going over 60mph is not having a gear tall enough for me to keep pushing above that. > I believe uprights are quite superior to recumbents when it comes to > climbing hills and that nothing can make up for it. The only sensible > thing to do is to stay out of the mountains if you are riding a recumbent. This argument makes perfect sense. ...At least for someone who rides down mountains with their breaks on so as to not soil themselves by possibly breaking a mind bending 30 mph... -Zenin

Our leg muscles and blood circulation are designed by nature to withstand the effects of gravity, but to have your legs elevated above your hips while pedaling a bicycle is not part of the design.

When you fall off an upright you will most likely land on your hip or shoulder, not your tailbone. You do not know what pain is until you have landed on your tailbone.

You will simply kill yourself. > And it still amazes me these claims you make as to actually being a > 'bent rider...your statements just don't have the ring of experience.

You bet I ride the brakes going down a steep hill, especially if it is a curvy steep hill. As for it being a problem, the only problem I foresee is one for you when an ambulance is picking you off the pavement and carrying you off to the hospital - or maybe the morgue. > It sounds to me like you're afraid generally to go fast, so you're > trying to make believe the entire sport of bicycling is done at slow, > tedious speeds (ie, all uphill, riding the brakes down). 20 to 30 mph is not a slow speed, but is about what bicycles are designed for. To want to go faster than that is just asking for trouble. It is not fear that makes me keep my speed down, but good old fashion common sense - something sorely lacking in the world today. I enjoy riding my bikes on the flats; I do not enjoy riding my bikes in the hills. > For me I like bicycling because I like to go fast. If I wanted to go > slow I'd take up jogging.

Hey db, I'm currently on my second tadpole trike, a 2004 Catrike Speed. I bought it from Calhoun Cycle in Minneapolis, MN, without a test ride. The re-assembly was no problem; but I did have a few issues with some details. For instance, the front wheel spoke tension is very low (need to get that fixed). Calhoun is a great dealership, which I highly recommend, BTW. Though it's a beautiful design, I wasn't sure about the Speed at first. I was pretty slow on it while I was building up "recumbent muscles." Handling is "thrilling." That is to say, very sensitive, with noticeable pedal steer and obvious brake steer (exacerbated by very powerful Avid disc brakes). You don't so much steer the Speed as you think about turning, and it goes there. Any more effort than that and you'll probably flip the thing. I kid you not. I had it on two wheels numerous times in the first few days of riding. For several weeks, I wasn't comfortable at speeds over about 20mph. BTW: The headrest is a must-have, especially the new suspended version. I'll be buying one of those soon. The unsuspended one can be pretty jarring. Now that I've logged some miles on the Speed, I feel more comfortable and safe than I felt at first. I'm definitely faster now - very fast, in fact. I find myself spinning out in top gear on occasion, and still feel confident at that speed (though I am very careful). I still won't ride on streets with any traffic to speak of. I haul the trike around in my hatchback, preferring to ride on paved bike paths, in big empty parking lots and in new housing developments (before the houses are built = no traffic). There are, of course, intrepid tadpole trike commuters out there; but I won't be joining their ranks. I value my life more than that. Though the Speed is even more thrilling than I had imagined (read: white-knuckle ride), it is a helluva lot of fun. It really is like a 3-wheeled pedal-powered go-kart in many ways. The brakes work *very* well if you ever get going faster than you'd like. You just have to be careful to apply them evenly. I'm getting to where I can do emergency stops from high speeds very well, with minimal back-and-forth twitching (from uneven brake application/modulation). My first tadpole trike had a single lever to control both brakes, which worked pretty well. This one, you gotta watch how you apply the stoppers. That being said, there's nothing like a tadpole trike if you like to cruise along gazing up at the trees and the clouds, with no worries about falling over. I love to find big open stretches of pavement (sans cars), and just stare at the sky while pedalling at a leisurely pace. It makes stress melt away. It's wonderful relaxation therapy, and a gentle workout all in one. Can't beat it. It makes me think that cross-country touring might be a great experience if I could find a suitably safe route. See if you can find a trike owner in your area to give you a test ride. I think you'll be very happy with a tadpole trike.
