Basic fishmouth cutting tutorial for bike builders

This basic tutorial will cover cutting a simple 90 degree fishmouth into round and square tubing. A fishmouth is a semi circular cut taken at the end of a tube so that it can be joined to another round tube. In bicycle frame building, it is often necessary to cut several fishmouths into the ends of the steel tubing where the head tube or bottom bracket will be installed.

Velomobile concepts by Neil

Hi Brad and Kat,
Thank you for all the inspirational projects and build information offered.
Although I am currently not in a position to physically build any projects yet and still undecided on which one to even build first, I have been spending some time developing “virtual” vehicles and attached are two conceptual overlay images that I would like to share. Although these are still very conceptual illustrations, it has been a very enjoyable creative process and have received a large amount of satisfaction from the results.
First a little history, I have had a very strong interest in HPVs (human powered vehicles) for many years and periodically during that time have done many very basic conceptual sketches. Recently, my interest has been more specifically focused on “Velomobiles” and have been gathering information to create my vehicle, which I am currently in the process of deciding the final design configuration — so many possibilities lately — to meet my design needs!
For the past few years, after seeing some illustrations others had done involving velomobiles, decided to expand my illustration/drawing skills and create some considerably more detailed work — especially after being inspired by some of your project photos.

The first illustration overlay I started was of the Marauder Lowracer, the vehicle position in the image was at what I consider a perfect angle and could see some very interesting possibilities.
The next project was the Streetfighter Quad, which was a bit more challenging since having the idea of using aluminum for the shell — especially when attempting to visually illustrate this material unpainted in the top section. I also pushed the design illustration just recently, by adding considerably more detail than the previous image, and although I can see more that could be added, believe it is finally complete.
I am looking forward to creating more design concepts from some of the images collected, including the process of being able to create these in a shorter period of time. In addition, as I get closer to determining the final configuration of my vehicle, will possibly even do a few as 3D models before actually doing a physical build — very possibly this year.
Hope you enjoy the images and thanks again for the inspiration!

The “I Didn’t See the Cyclist” Defense

The front windshield of Sommit Luangpakham’s vehicle was smashed in after the crash in 2009, injuring five cyclists.


This is a great editorial by Bob Mionske, in my opinion, and worth reading. 

It’s the “ignorance is bliss” defense: “I didn’t see the cyclist, and I didn’t intend to hit anybody. It was just an accident. It’s nobody’s fault.”

Well, yes, it is somebody’s fault. It’s your fault, it doesn’t matter that you didn’t “intend” to hit somebody. You did hit somebody, and if you didn’t see the cyclist because you weren’t paying attention, it’s your fault.

Weight bench bike in France

“Greetings from central France. I originally hail from the north of Scotland so no jokes about garlic and onions on the cycle, please!

Anyway, I have been recycling bikes for years and keep myself going in France by selling recycled bikes at markets. There is not much of a skip around these areas, so when a weights bench turned up, it was hauled straight into the van.

The picture is indoors due to lovely weather, and, yes, there is still a bit of work to do. Incidentally, it’s all nuts and bolts at the moment. Will weld it up when totally happy with end result.

Any comments or constructive criticism gratefully received as this is my first attempt at mutant mechanics.

Happy building. Simon.”

Looking great so far, Simon. Using parts of a weight bench is genius! Join the Atomic Zombie Builders Forum and tell the community all about your recycled bike. You’ll get a lot of help and suggestions from our friendly community. Merci beaucoup!

Electric Warrior recumbent tadpole trike in Norway



Some months ago, I purchased building instructions for the “Warrior”. Very good and highly  valuable, thank you very much! Since I had no previous welding experience, your “welding basics” tutorial also helped me a lot.

I was “brave” enough to go for round 50mm/47mm tubing in place of the square tube frame. It gave me grey hair before I mastered welding round thin walled tubing. Very difficult for a beginner, but a lot of practice helps (and a good grinder). Your instructions of how to make use of different existing bicycle parts were most welcome. It saved me a lot of research work.

Since I live in a place with a lot of hills, and almost no flat areas, an electric motor is almost mandatory to get anywhere. So, I purchased a “Golden Pie” and 38V LiPo batteries.

The trike was finished and first test ride was made today. It is NOT the right time for bicycle trips in Norway at this time of the year, but I cannot wait for the spring to get this thing tested. After some adjustments of the handlebars to maximum comfort, it was ready for a ride. It rides perfectly! Very stable and easy to handle.

Even on ice and hard snow it was no other problems than some painful “bone rattling” over some very bumpy parts in the road caused by poor clearing of the snow and ice. The motor really does a great job to zoom up hills that otherwise would slow me to walking speed. I hope this will be a great alternative to my car when commuting to job, and for pure fun.

Thank you very much for your instructive web site!


Bjørn Furuheim, NORWAY”

Wow! That’s a great, rugged Warrior trike designed for your climate. Thanks, Bjorn for your kind words. Hope to see more bike creations from you.

Michigan handmade wood high wheel bike




“My name is Jon Jacobs from Samaria, Michigan. I’ve built three wood bikes, a 48 inch highwheel a 36 inch kids’ highwheel and a 72 inch monowheel.

Thank you. I have plans available for the kids’ highwheel. Jon.”

Great bike, Jon. A work of art for sure. Send us pictures of your other handmade bikes, too. Keep up the great work!
