What will happen if you make the bicycle frame with only the spring?

Some bicycles for running on rough roads and mountain roads are equipped with suspensions for absorbing shocks in front and rear tires. Better yet, the dream movie that the bicycle itself has been replaced with a spring by cutting off the frame is released as "Why do not you make the bicycle itself with a spring?"

THE BICYCLE OF SPRINGS - YouTube


It appears that "Hello Internet!" Appears in Norinori, as everI really made a flaming radiation guitar that appeared in Mad MaxRiI built a huge robot that I can get on and get on board with parts purchased on eBayThere's a YouTubercolinfurzeMr. This time, I changed the mountain bike that I brought from the scrap repository to springbikes.


This prey is made by Challenge ... ...


A motorcycle called Emulator. I have not heard much, but apparently it seems to be a bicycle sold around 150 pounds (about 20,000 yen).


"Hey! Spring, I'd like to order!" Colinfurze who orders with a strange pearl. However, it is delicious that the line is not connected to the telephone.


Spring arrived by saying "Ja!!" This spring ......


It connects like this, instead of the pipe of the frame.


First connect the springs together to make a long spring ......


Cut the frame boldly with an electric grinder. It is a scene that you faint if you ride a bicycle.


And screw the spring around the pipe part of the frame that I left ...


welding.


First, we succeeded in making the "seat tube" spring under the seat.


Next, we are going to spring up "top tube" from seat to handle. Cut the pipe while scattering sparks.


I will apply a spring, but at this point I already have a guyagguha.


I will weld for the time being.


Among the triangles in front of the bicycle frame, Challenge made Emulator with two springs. From here more ...


Cut and cut down the thickest pipe "Down Tube" that was left.


The moment when the pipe breaks, the bicycle collapses as if I was out of breath. Even sashimon colinfurze collapsed while laughing loudly.


Although I tried installing a down tube somehow, it is obvious that there is not enough strength for people to endure.


That's why, "Hey! I want a stronger spring, but I'm calling (pretending)."


A thick spring arrived.


It is a thick spring that looked quite durable, but still people got in a state of no goodness if they ride. This will not be a talk.


And after a couple of weeks ...


An inattentive spring arrives that surpasses the last time. For the purpose of this project, it is a spring ordered by custom order.


A spring that has never been seen in normal life is about to become part of a bicycle.


"This time it looks okay!" Said colinfurze, a goddess. Finally, it seems that the spring bike that can ride properly is completed.


"Ja!" And a test bike on a spring biased spring.


Running in the garden ......


It seems like I can run on my expectations properly. This has expectation.


However, it is unavoidable to make the angle between the front wheels and the rear wheels strange if you put a little effort.


When you try acrobatic action, you can see that the whole car body absorbs Gagnaggia and shocks.


Colinfurze says "I'm sure this is for bunny hops," trying out the way to jump on the spot. However, surprisingly surprisingly it was able to properly bunny hop.


Even when running on a wavy bad road, clear while clearing the car body.


When jumping from jumping with a jump ... ...


Gunuu shock absorbed throughout the car body.


Even if it collides head on the wall while running, ...


Although it deforms, but since it is a spring, it seems that it was supposed to be able to run as if it was in its original shape as if nothing had happened. It seems that riding comfort and ease of running were another problem, becoming a bicycle that can run as it is.
