Picture of How to build a great big tall bike.

Hey, here is my great big tall bike.

 I was given lots of parts of bicycles and as as none of them were any good or complete I decided to uses up all the parts that I could to make something beautiful.

I used two mountain bike frames and an extra sets of forks ( three in total) and a bmx back wheel.

I made it up as I went along and it was lots of fun.

I used an arc welder (stick welder) which is not ideal for bike frames but if you don't mind burning a few holes into the frames then it is ok;  a Mig or acetylene welder would be easy peasy.

My welding is not so good so I jumped around on the frame before riding the bike to make sure that it was safe.

It rides like a dream.




The first step shows everything in an animation form ( this is also in the film) and then the subsequent steps show more detail.

Here is the video ( which is essentially someone riding the bike around in circles for 1 minute and eight seconds); enjoy.

Step 1:

If you were too busy to watch the film then here is a quick animation.
 

Step 2: The forks.

Firstly I took the front wheel off.

I took my second pair of forks ( No. 2)  and cut them top and bottom as shown, as shown.


I cut the drop-out ends off the original forks.

I slid the No.2 forks onto the original forks and welded them on.

I took another set of forks (No.3) and cut them at the top and slid and welded them onto fork No.2.

I thought that it would be a good idea to put a brace across the forks for strength.

Unfortunately I had no metal at all; I used the front chainset from frame number 2 and welded it across; it looks rather stylish.

Love the animation - you ought to write another instructable on how you made it.

Thank you Kiteman; it's just stop frame animation.
Still, I'm sure it would be popular.
+1. Absolutely. Show us how you did it.
The animation is very effective.

I,ve been trying to work out a cool tall bike design to use up some of my old bike parts. I think this might be it. Great work and great i'ble. Thanks.
