MY PERSONAL STORY CONCERNING CYCLING & RECUMBENTS

There is nothing I am about to share here that I have not shared before. I decided to put it altogether in one article so others will know where I am coming from and help them understand my passion for tadpole trikes.

To start with all my life I have been an avid cyclist starting when I was about 6 years old I think. An older cousin helped me learn how to ride a bicycle. I never had training wheels. I just learned to balance my bike right from the start. I first rode a 20 inch bike and gradually got a 26 inch. As a teenager I bought with my own money a white Schwinn 3 speed internal hub English racer style bike. I inverted the handlebars to make it into what was  called a  racer type bike. I was the fastest cyclist where I grew up.  I had a 52 tooth chainring installed and I could really go on that bike.

Stingray style bicycles became popular in my teen years so I made my own 20 inch bike with high apehanger handlebars and banana seat. I could ride wheelies until I decided to end it (literally miles)… far longer and farther than anyone else in town.

When I was in the Navy I bought a lightweight Gitane racing bike … a 10 speed which was all they had at the time. It was a pretty sky blue but it was a prima donna . I swear that spokes would break if I looked at them crosseyed. Over the following years I had several different bikes and continued to ride. It was not unusual for me to ride 50 to 100 miles in a day when I had the time to do so. I was still doing this into my late 30s. I moved to Georgia and found that there was no safe and practical place for me to ride so more than 13 years passed by when I did not ride. I moved back up to Indiana and soon after started back cycling. I found out that there are local bike trails available to ride where I live so I started riding on them. That was almost 17 years ago during which time I have accumulated well over 120,000 miles on them.

As time passed by and my body aged I got tired of dealing with all the discomfort involved in riding a diamond frame bike. It greatly took away from the fun and enjoyment of cycling. I had heard of recumbents and seen a couple of them. I had heard that they are comfortable to ride so I decided to make a recumbent bike.

I used  “donor bikes” and bought a few things like a recumbent seat but I managed to come up with a recumbent bike I started riding which eliminated all the discomfort I had been experiencing on a conventional diamond frame bike. I was really enjoying riding a bike once again. After putting a couple of thousand miles on my homemade recumbent I bought a Sun recumbent bike. In fact, I bought two of them … one for my wife who used to ride with me. They were better bikes than the one I made so all was going well. I put a couple of thousand miles on my Sun recumbent.

However … winter was approaching and I wanted to keep riding. I was concerned about attempting to do so on two wheels as it would be quite risky and dangerous.  I had heard of tadpole trikes so I decided to make my own. I was still working full time so it took me about 3 weeks to design and build my trike. I cut up my homemade recumbent bike and used parts of it to make my trike. It was made out of mild steel so it was heavy. It rode and handled great though as I had done my homework and got everything right in  the construction of it.

I rode it thru the winter and was so happy to have it as it was so safe and so comfortable compared to my recumbent bike. I did not have to concern myself with “going down” riding in snow and  on ice. I made it thru the winter and as planned I switched back to my Sun recumbent bike come Spring only to discover that I much preferred riding the tadpole trike. So I switched back to the trike and never looked back. My recumbent bike just sat around so I decided to sell it. I had my wife’s recumbent bike I could ride if I wanted to. She had stopped riding it and it just sat around.

After I put a couple of thousand miles on it I was able to buy a new 2009 Catrike Trail and I sold my homemade trike to a guy who said he planned to motorize it. As things have always gone for me I was not even able to get the cost of the various components I had purchased to build it.

I loved my 2009 Catrike Trail and it’s “space frame” as they call the solid all one piece frame. After about 3 plus years I discovered a “hairline crack” along the edge of a weld on the underside of the cruciform crossmember. Being a professional weldor I understood what I was seeing and the concern of future failure of the weld so I contacted Catrike sending them this picture to show them what I was seeing. They replaced the frame under warranty.

I was thankful that I received a new frame however, I was not happy that I could not get another space frame. This was 2013 and Catrike had changed the design of the Trail model.  The new frame featured an adjustable seat back angle and the frame design change added 2 pounds of weight to the trike. Ever since then I have wanted to find a used space frame to buy and go back to it. I have no use of the adjustable seat back and definitely don’t like have the trike weigh more. I was hoping Catrike would still have a space frame around that they could send instead of the new design but no such luck. I did not think about it at the time but I wonder if I could have got an Expedition frame and paid the difference. In hind sight I wish I would have checked into it. My 2009 frame was silver but Catrike told me I could have any color they were currently offering so I went with green. All of my old components off of my 2009 trike were reused with this 2013 frame. That is why I have a silver boom with a green frame.

I rode my Catrike for about 7 or 8 years I think before I made the decision to motorize it. BionX  was the big name in e-motors at the time so I went with BionX. That turned out to be a big mistake as it was not only expensive but it didn’t hold up and I went thru a big mess trying to get another motor that worked right … which I never did. So I asked for and received a full refund. This was just before BionX went out of business so it turned out to be good timing. I then tried a Golden Motor and it was faulty right out of the box. I got a refund on it as well and  then went with an eZee hub motor which has been great … until about 6 months ago when a problem developed.  The power would shut off just like I was turning it off with the battery key switch. I checked various things but could not find anything wrong. I suspected that the problem was in the controller which is a rather expensive item to replace. Consequently I did not jump on replacing it. I just dealt with the problem in frustration until finally recently I decided to take the gamble and buy a new controller. I was elated to discover my hunch was right. The new controller fixed the problem and now I am once again enjoying my e-motor assist.

Yes, I am sold on tadpole trikes. I new have about 100,000 miles on my Catrike. It is truly a well engineered and built machine which I highly recommend to anyone looking for a recumbent tadpole trike.

Well, this is my story and I am not only sticking to it but I am stuck with it.

THE WAIT IS OVER–NEW TRIKE HAS ARRIVED

Some of us follow this fellow tadpole trike rider. He has interesting videos which are always well done. Here is one of his recent ones. The new trike he ordered has arrived. Needless to say he is a happy camper … or maybe I should say happy triker. He went with e-motor assist on this trike and is really enjoying and appreciating it. May you enjoy many thousands of miles of trike riding on it David.

ONE USUALLY GETS WHAT THEY PAY FOR

“One usually gets what they pay for “… an old adage most of us are familiar with. And  it has proven to be true in most cases. The lower the cost the lower the quality and usually fewer features and cheaper components. When it comes to recumbent tadpole trikes it certainly applies. For sure these trikes are expensive and there are many who just don’t have the money to buy a high quality trike. They have no choice but to buy cheaper products. I understand that but I will make the suggestion to buy the best you can afford. Save a little longer so that you can buy a better quality trike. Buy a used trike and save hundreds off of the price of buying new. If buying used if you don’t know much about trikes and mechanical matters have someone knowledgeable involved in checking out the trike you are considering buying.

Years ago I put together a page on this blog to help people know what is offered in the way of new trikes and the prices involved. Please note that it is not up to date. Models may have changed and prices no doubt have increased but at least this should give you some idea of what is available and the price range. I also have another page concerning used trikes. And I have an article I wrote on buying a used trike.

Very few people are satisfied with their purchase of trikes with very little gearing available on them so I would advise against buying a trike which offers a small gear range. If you have any hills to climb you will definitely regret it. And one trike I definitely would advise against is a Mobo. I don’t know of anyone who wasn’t disappointed after purchasing one. I have never read or heard anything good about them. Definitely it proves the adage … you usually get what you pay for. In short, buy the best you can afford. It will help reduce regrets. One more word of caution … just because a trike has a well known name does not mean it is high quality. I won’t name names here but one name comes to mind that is very popular but I consider them on par with a Walmart bicycle when it comes to quality.

PRACTICING PATIENCE WHILE WAITING ON A TRIKE ON ORDER

Most of us know that this PLANdemic (not pandemic) has made a big mess of lots of things in life. Bike shops are struggling to get bicycles, trikes and all sorts of accessories delivered in a timely fashion once ordered. I was in my local Catrike dealer the other day. They not only don’t have any Catrikes available to display but because they don’t and because it will be awhile before anymore come in they removed the display racks. They have several different models on order but it will be a long time before any arrive. So as frustrating and aggravating as all this is it all comes down to practicing patience … as hard as that is to do. It helps to have a trike to ride while waiting on a new one to come in. Such is the case for David. He is waiting on a new trike he ordered.

OVER 96,000 MILES AND COUNTING … A TRIBUTE TO CATRIKE QUALITY

I bought my Catrike Trail new back in 2009. Now, some 12 years later I have over 96,000 miles on it. And I am elated to be able to report that it is  like new as far as mechanically. I would not be afraid to start off on a world tour on it just as it is. So I don’t mid tooting their horn. They make an excellent product.

That does not mean that there isn’t room for improvement. I have had problems with their wheels not holding up to what they go thru here where I live and ride. Between bad pot holes and bumps all three of the Catrike wheels have been destroyed. I replaced them with more Catrike wheels only to have them destroyed even quicker than the original ones. So I stopped buying the Catrike wheels and bought some heavy duty BMX rims and had my local bike shop lace my hubs into them. The BMX wheels have held up great and I no longer have spoke breakage problems like I did with the Catrike wheels.

My 2009 frame

 

Other than the wheels I can’t say that I have had any other issues which come to mind. Of course, I have experienced the usual … various components wearing out such as tires, wheel and headset bearings, brake pad and rotors, shifters, derailleurs, chains and sprockets wearing out, etc. Even so most of these have lasted incredibly long … far beyond their expected life.

About 4 years after buying my 2009 model I discovered a hairline crack alongside of the weld on the bottom side of the crossmember. I am a highly experienced and accomplished weldor so I knew what I was up against. The weld could fail anytime or it could last for many years. Catrike warranted the frame so I contacted them about it sending them pictures to show them what I was talking about.

In my opinion I think they should also have placed a gusset on that side like they did the other side.

Anyway, they replaced the frame under warranty. However, they no longer offered the space frame like my 2009 model had. They sent their new frame which was a 2013 model. I don’t like the new frame and ever since I got it I have wondered if I should have taken my chances on that weld and kept the 2009 frame. Too late now.

For what it is worth I have never seen any pictures of a Catrike with a broken frame. I certainly have seen pictures of other brands with broken frames. In all the years I have been following and reporting on tadpole trikes I have never heard of a Catrike with a broken frame. I would guess that they exist, but it is interesting that I have not seen or heard of any.

My 2013 frame

 

I am sold on Catrike. I don’t think there is a better tadpole trike made regardless of the cost. And I don’t think there is a better engineered tadpole trike. There is one competitor which I won’t name other than to say they claim to have inspired engineering. Their trikes are quite expensive but in my opinion Catrike is much better engineered and built. I would not trade my one Catrike for three of their models of my choice unless I would be allowed to sell them and buy what I want.

Thru the years I have made changes adding and removing various stuff. Here is a picture of my trike with a canopy I had just installed on it. I also have a hub motor in the rear wheel and two batteries.

I have never owned any brand than Catrike but I have ridden a few other brands. It is a clear choice for me.  Now if I could just figure out what they were thinking when they name it. I am referring to the spelling. I know it is pronounced CAT TRIKE, but it sure isn’t spelled that way. CAT RIKE … CA TRIKE. Several times I have seen people spell it CATTRIKE. I wonder why Catrike didn’t do that. But no, they spelled it ….

 

… just to mess with our minds, me thinks. Hey, whatever you ride and whether you can spell it or not …

TADPOLE VS DELTA … “IN” VS “ON”

We all know the saying “different strokes for different folks”. When it comes to adult tricycles we have choices … many choices actually. But I am only interested in talking about “recumbent” so that narrows down the selection some. Basically there are tadpole trikes and delta trikes.

One big difference in these two configurations is the seating position. On a delta trike the rider sits “on” the trike. On a tadpole trike the rider sits “in” the trike. That is to say the seating position is much lower so that the rider is much closer to the ground. There are exceptions to this, of course, as some customers want to sit up erect and high rather than be “recumbent”. There are big trade-offs with this in the handling dept. A low slung tadpole is a blast to ride as it handles like it is riding on rails. But a tadpole with a high seat has no advantage over most delta trikes in the handling dept. Oh well, if that is what they want they can have it. I may be nearly 74 years old but I still enjoy riding a “recumbenttrike which handles great and is so much fun to ride.

Anyway, most delta trikes and tadpoles with high seats can’t begin to compare to a low slung tadpole when it comes to handling.

 

A few months ago I rode a Catrike 700 … a trike built for speed and handling with a 25 degree seat back angle. I have always wanted to ride one so I asked my local Catrike dealer if I could. That is about as recumbent as one can get on a recumbent trike.  My trike is a Catrike Trail which has a seat back angle of 45 degrees. That is quite a difference. I have to admit I preferred riding my Trail over riding the 700. Maybe if I were in my 30s instead of my 70s I would choose the 700. Truthfully at my age I did not find the 25 degree angle very appealing to me. I have never ridden a Catrike Expedition which has a 37 degree seat back angle. I think I would like that angle as the 45 degree angle always has disappointed me in that it won’t go back down any further. If I am going to have an adjustable seat back I would prefer it go back down further rather than up further. Oh well, Catrike didn’t see fit to provide this in their design build. They seem to cater to those who prefer not having a recumbent trike.

Delta trikes can tip over easier than a tadpole. Again, there are exceptions to this. Tadpole trikes can and will tip over. As dirty Harry said … ” a man has to know his limitations”. Delta trikes tend to be much longer than tadpole trikes. This may not be an issue for some folks but it is a real “turn off” for me.  Definitely most folks seem to prefer the tadpole design over the delta.

IN vs ON … speaks volumes to me. IN equates to a sports car. ON equates to a family sedan. So whether you ride a “Corvette” or a “Rambler” (and I am not talking about TerraTrike Rambler) be safe and …

REAR WHEEL DIAMETER … 20 VS 26/700

Frequently the subject of rear wheel size comes up as people want to know which is better or preferable. I don’t think I have ever addressed this in all my many postings. Since it is asked so frequently I figured it is past time to do so.

Well, like most everything else there are pros and cons involved. I have had both a 26 inch rear wheel as well as a 20 inch rear wheel. Personally I didn’t notice all that much difference. Never the less I will cover the good, the bad and the ugly of the matter. Don’t ask me why I said that. All I can say in response is that it happens to be the movie playing on GRIT TV as I am composing this.

Let’s start out by covering the obvious … or at least what should be obvious. Having three 20 inch wheels on a trike means that you only need to deal with one size when it comes to spare inner tubes and spare tires to carry along with you.

What may not be obvious is in the realm of performance and handling as well as weight carrying capacity. That is something to consider if you plan on touring and loading the trike down with gear.

A smaller diameter tire will accelerate faster than a larger diameter wheel. That being said a larger diameter wheel will result in a higher top speed than a smaller one. Of course, I am talking about having stock gearing and not messing with the gear ratios. Once one starts changing the gear ratios all of this can and does change. One can accomplish the same things with existing wheel diameter by changing the sprockets diameters in use.

A larger diameter wheel will roll over objects easier than a smaller diameter wheel which means that a larger diameter wheel yields a smoother ride than a smaller diameter wheel.

A smaller diameter wheel is stronger than a larger diameter wheel so it will carry more weight and handle better. A larger diameter wheel has more flex to it than a smaller diameter wheel so it is noticeable in cornering.

A smaller diameter wheel is usually less costly than a larger diameter wheel when it comes to tires to install on it. That being said 26 inch is a very common size with lots of tire choices available. So one might very well come across some good prices on tires.

A smaller diameter wheel requires a smaller trike frame. That may or may not make any difference to people. It is just something I wanted to be sure to point out.

When it comes to folding a trike again obviously a smaller diameter rear wheel folds smaller than a larger diameter wheel.

I have mainly been talking about 20 and 26 inch wheels. I only mentioned 700. Another popular size is 24 inch. They have their advantages but know that 24 inch tires are not as common as 26 inch so the selection won’t be as good.

Changing from one size to another may be problematic as the trike is designed for a certain size. The frame may not be built so that a larger diameter wheel and tire will fit. Also making a change in the rear wheel size will effect the trike’s handling and it may not be as safe. Raising the rear of the trike with a larger diameter wheel/tire will result in lowering the front end of the trike. This will bring one’s feet closer to the ground and cause more of a concern in the matter of “leg suck” and injury.

Anyone considering a hub motor a larger diameter wheel provides more room for a motor to be installed. That means there are more choices of hub motors and with more space available a more powerful motor can be installed than what will fit on a smaller diameter wheel.

Personally I prefer a 20 inch wheel over a larger diameter. It comes down to a personal choice. With either choice one can …

TRY BEFORE YOU BUY

Face it, there is simply wisdom in trying as many trikes out before purchasing one. They are not cheap to buy and once they leave the store their value usually drops off considerably. Some dealers will work with customers if they are dissatisfied with their purchase but there is no guarantee of that. It can be risky business to buy a trike you end up regretting and facing the aftermath. So common sense dictates that we do our homework or should I say leg work (actually both) and go check trikes out riding as many as you can and if possible any you find yourself interested in taking a much longer ride on them as it may help you discover something that wasn’t noticed on a short ride. I don’t know how many dealers there are around which are willing to do this, especially if they don’t have easy ready access to someplace customers could ride from their store and be gone for an extended ride. I don’t know what their policies are as far as requiring a security deposit to take a trike out for an extended ride. That reminds me of a true story of a business neighbor I once had. I had a welding shop and he had an automotive transmission repair business. A guy came into his place of business asking to borrow a log chain. The business owner told him it would require a security deposit. The guy told the business owner if I had that much money I would just buy one. The business owner told him that if he didn’t bring the chain back he did just buy one. I fully agree with the business owner in his practice of requiring a security deposit of a sufficient amount to cover replacing the chain. So I don’t know if any trike dealers require a security deposit to cover the cost of the trike but I can’t say as I blame them if they do. Anyway, good hunting and may you find the trike that is just right for you.

TADPOLE TRIKE RIDING … EXERCISE FOR EVERYONE

As more and more people discover tadpole trikes and all they have to offer (comfort, safety, fun and, of course, exercise) they sell themselves. This video and my next posting following clearly illustrate a typical scenario … taking a ride on a tadpole trike and getting “hooked” like a fish … followed by the process of finding the right trike and buying it. Let’s go along on this fishing expedition to witness this process …

DIFFERENT STROKES (trikes) FOR DIFFERENT FOLKS

We are all individuals with different tastes, likes, dislikes, values, thought, etc. As they say … it is what makes the world go around. Some drive a Ford while others drive a Chevy. Some drive a Jaguar while others drive a Yugo. Speaking of Yugo … that reminds me of a joke. A guy goes into an auto parts store and walks up to the counter. The store employee asks him how he can help him. The man says “I’d like a rear view mirror for my Yugo”. The salesman pauses for several seconds as though he is thinking about it. Then he replies back … “Sounds like a fair deal to me”.

Where am I going with this you ask? Well, I will tell ya. Did you ever take a look at the list of trike manufacturers and notice that there are more than a couple? There are a whole lot of them. And most offer several models differing from one another. Tadpole trikes are not cheap to buy. We as individuals can’t all afford the “top of the line” and even if we could not all of us would want what may be considered top of the line. Some can only afford the lower cost trikes and some are happy enough with the lower cost trikes. HERE is a list of trikes by their cost.

Various factors come into play when it comes to selecting the trike which is best for us. Most certainly there is great wisdom in trying numerous brands and models before buying. Research is quite important. We should educate ourselves as much as possible.

Some trikes may appeal as far as cost but they may also not be well designed. They may not handle well. If you are only going to ride very slow and be very careful this may not be an issue for you, but if you like to ride faster and corner hard it would be a major issue.

Some trikes are equipped with high quality components while others have lower “entry level” components which may be a problem as time goes along. On my own trike I upgraded to much higher grade components and was glad I did.

Some trikes are well made and easy to work on while others are poorly engineered and a real pain to work on.

Impulsive buying is definitely not recommended as it may very well lead to buyer’s remorse. Like a car once the trike leaves the store it loses considerable value. There are dealers who won’t take back a trike for the price paid for it even if it is brought back 20 minutes later having never been unloaded much less ridden. Nobody wants to be a victim of that scenario. It is “buyer beware” so choose wisely.

We all want to …

CATRIKE ROAD AR … LIKE A TRUE CAT IT DONE SNUCK UP ON US

Cats are known for stealth … sneaking up on their prey undetected. Well, it looks like Catrike is sort of following suit. They are quietly introducing a new model … another full suspension trike. It is the Road AR. There isn’t much out about it yet. Catrike does show it on their website. They just have been rather quiet … no fanfare. HERE is a webpage about it. They say that it is expected to be in stock by the end of May. They show a price of $3550. That is $400 more than the regular Road model which has rear suspension only. It is somewhat like a trimmed down Dumont. It has 20 inch wheels all around whereas the Dumont has a 26 inch on the rear. Unlike the Dumont this Road AR does not fold. They offer it in 8 different colors.

Here is what Catrike says about this model:

The road AR is a vibrant and efficient machine. A progressive linkage air shock and CNC swing arm provide a highly adjustable suspension platform paired with the new patent pending front suspension to take the edge off the road for a smooth ride. An optimized cockpit design is supportive enough for a comfortable daily ride, commute or weekend adventure without sacrificing any control or performance. Lean into the corners with confidence. The road-AR brings excitement to the journey.

Here is a closer look at what some say is the best engineered front suspension on a tadpole trike to come along to date.

So if you are looking for a quality built well engineered full suspension trike which is hundreds of dollars lower in cost than most others you might want to consider this new model. I can hear it purring. With this trike you should be able to …
