EVOLVE TRIKES


evolve-trike-ready-to-ride

Evolve Trikes  … interesting concept, but they are sure having problems getting into production and to market. Years and years seem to be passing by and still they are waiting for things to come together. It just doesn’t seem to be happening. Yep, they seem to be having trouble evolving to market.

Since it’s inception they have made some changes in its design. The main boast is that it folds faster and smaller than any other trike.

When I look at the design construction of trikes I am always concerned about how ell they are made and whether or not they are likely to fail. Mind you I am not an engineer, but I do have well over 50 years experience at welding and fabricating. In welding my “specialty” was repair welding. That means I worked on a whole lot of things that failed and required repair. In making the repair it was usually easy and obvious to see why the item failed. And in repairing it I always made it much stronger so that it didn’t fail again. Looking at many trikes I see areas of concern in many of them. They just look weak and apt to fail. Many folding trikes concern me for this reason. This one not only is no exception, but it is even more of a concern as it just looks weak. Any trike can have a failure, but some seem to have far more than others. Again, looking at the way they are constructed I can see why. A simple basic rule is that the more complex something is the more likely it will have issues over something with less complexity.

HERE is an article about this trike. And HERE is BROL’s article.

Here it is disassembled and folded up into a suitcase. The video  below shows how it is done.

I don’t know what the weight limit is for the Evolve trike, but I think that it would be best for those who weigh very little. A heavy rider would stress those areas which are already suspect of failure.

I personally don’t think I would buy one of these trikes as it just has the appearance that problems would develop due to failure in one or more parts of the frame.

The folding hinge is quite often a concern and this one is no exception. When I look at something like this the thought that comes to mind is “designed to fail” due to being underbuilt. Mind you, this is far from the only tadpole trike which in my opinion looks underbuilt.

Another factor is wear and sloppiness developing in these areas. Things get loose and movement takes place where there should be no movement.

I know that the Evolve people are not going to like what I have said here and perhaps some of you may not either. I have to say what I think about these things. I hope I am wrong and this trike would hold up well. But my gut feeling is otherwise. I like the concept. I am just concerned about the quality of the build. Manufacturers underbuilding products brought a lot of repair work my way over the years. I would not want a trike that requires repair and reinforcing it to make it stronger. That would be my concern here. This may be okay for someone who rides very little and needs a small folding trike, but I could not recommend it for anyone who does serious riding. I don’t care how good of a warranty it may come with and how good the company may be in taking care of customers … when you are many miles from home and have a major failure leaving you stranded it is not fun. Nope, I will stick with my non folding Catrike which I am confident in … that it won’t fail me. I like to …                                                       KEEP ON TRIKIN!                                       …. and ….

ENJOY THE RIDE!

MASA SLINGSHOT, A BIT OF NOSTALGIA

The era was the 1970s … 1975 as I understand is when the first of these were introduced here in the United States. A rather unique recumbent trike of the tadpole configuration came on the scene. Even though it originated in Japan it was the United States where they were most prevalent. They were big and heavy yet supposedly they were built for racing on oval tracks. Obviously they were not designed for touring and general riding. They were quite long compared to tadpole trikes of today. Their days were numbered and now they are more less a collectors item. Not only were they long, but they had a wide wheelbase so they are not too practical as far as fitting on trails and thru various openings. Speaking of being long … the chain on these was 13.5 feet long. That is a lot of chain in case you didn’t know it. Most modern day tadpole trikes have about 9 to about 10.5 feet depending upon how far out the boom is adjusted. Some say that these Masa trikes did not handle well and could tip over easily … that too much of the rider’s weight was on the back wheel. That being said you can also read that the trike handles well and doesn’t tip over as easily as modern day trikes. Take your pick. I give up. Well, I have already said more than I know about them. 🙂  So I won’t say anything more. I will just post a couple of videos where they are featured and talked about.

HERE are lots of pictures of two of these trikes.

GOPRO MOUNTS TIPS & TRICKS


GoPro cameras are very popular and take high quality pictures and video. Many tadpole trike riders use them. GoPro has numerous accessories and mounts available. Here are three videos explaining it all.

FOLDING ALUMINUM RAMPS


The last two days I have been busy working on fabricating a set of folding aluminum ramps for my friend to use to get his tadpole trike in and out of the back of his pickup truck. He only has a six foot bed so the ramps had to fold in order to store them inside.

Remember, you can click on the images and view them full size in a separate browser window.

They are 8 foot long with a 21 inch long section of 1/4 x 4 inch flat bar which lays on the tailgate.

There are hinges in the middle connecting the 4 foot sections of C channel and at the top connecting the C channel to the 1/4 inch by 4 inch flat bar. The flat bar extends back off the tailgate about 2.75 inches and is bent down about 15 degrees or so to match the angle of the ramps as they come up to the tailgate. Currently there are no angle aluminum pieces in place at the end of the 1/4 x 4 inch flat bar, but I think it is going to need this added to help keep the ramps from moving. On my truck they stayed in place well as is, but on my friend’s truck they don’t. I originally had in mind placing  aluminum angle pieces on the end of the flat bar and even drilled and tapped holes for them already.

These pictures show the ramps set up on my truck and not on my friend’s. I ran my trike up and down them to test the ramps out. The ramps work fine and will be a big help to him as his HP Velotechnik Scorpion fs 26 electric trike is quite heavy to lift. There is a 1/4 diameter round rod with the ends bent 90 degrees which goes thru holes drilled into the 1/4 x 2 inch flat bar pieces on the bottom end of the ramps. The rod spaces the ramps apart and maintains the spacing. It is also almost pavement level so it can be easily stepped over as the trike is rolled up and down the ramps. The C channel is quite thin so it is very lightweight to handle. I personally would have selected thicker stronger material to use but these were given to him free so they are what were used. If I were making ramps for myself I think I would make them shorter than these although there is some merit to longer ramps as they provide lesser incline to deal with. There are pros and cons to both. Longer ramps means more flexing … especially when thin wall material is used.

Where the two 4 foot sections of C channel are hinged together there is a 12 inch long piece of the 1/4 x 4 flat bar used to strengthen the joint in the flimsy thin wall C channel. It is bolted down on just one side to the C channel and simply lays down in the other C channel section when unfolded.

Here my friend is trying out the ramps for the first time.

Here is a short video showing the ramps I made being used.

I would estimate a total of about $100 for materials and hardware is involved in making your own. It could even be less depending upon the design and hardware used. I drilled and tapped holes in the 1/4 thick flat bar for the hinges.  Both pan head and flat head (countersunk) head screws were used as well as some 1/4 x 20 nuts where no 1/4 inch plate was used.

These ramps could be made in one day if you have everything needed and the knowledge and skill level to accomplish the task. Our local Metals Supermarket will do all the cutting free if the material is purchased from them. I have a horizontal cutting band saw so I cut it myself. I have found that most places don’t do a very accurate job of cutting metal to the specified length and this bothers me. When I cut metal I try to get it cut within 1/64 of an inch. Sometimes 1/8, 3/16 or even 1/4 inch more or less doesn’t matter in the scheme of things but sometimes it can really cause problems. I am a perfectionist in my work and strive for accuracy. I am retired from a lifetime of welding and fabricating so I rarely do much of this sort of thing anymore. Well, that is enough tooting of my horn. I just want you to be aware that if you have the metal cut someplace it may not be cut accurately.

So, if you have a need of a ramp loading system it can be done. Here is proof.

Of course, you can buy ramps. Depending upon what you get it will be a lot more expensive … about $400 – $500 for one popular manufactured ramp system. I just found another source for under $200 … 5 Star Manufacturing Telescoping Aluminum Ramps  They look like they would work pretty good. And I just found some others as cheap as $101.75. Walmart sells a set for $140.

I think this is a 7 foot set which would be perfect for most applications. The only thing is I don’t know about how well they would stay in place without doing something to help keep them in place. They telescope in to about 4 foot in length so they would fit readily in most any type of vehicle.

With ramps to help us load and unload our trikes it will help us to …
