I'd like a mountain bike that is different.
But I haven't decided what style I want, I don't like the pure color frame.
Do you design your own frame paint？Is there a special meaning? Is it complicated to operate？ And the total budget？
Post a picture of your special bike, what kind of mtb frame pattern design is popular in 2019?

Go to the Framebuilders section on the BF front page and read on what you might have do. It's not (repeat, not) cheap and easy to achieve something that is nice and durable. I have just finished one discussion started by TiHabanero on this and it was worth every minute to understand what can (or might have to) be done.

For something different I have blued three frames so far instead of using paint.

All the effort is in frame prep, taking it down to bare metal and washing with a degreaser or detergent is important. Then you simply apply bluing acid with a rag, rub, and reapply until you achieve the desired colour effect, and top coat with lacquer or epoxy. The acid oxides the surface iron content in the frame (so it won't work on aluminum) and on chromoly creates a warm brown hue to give an organic old bespoke look. I like older steel mtb's as they are dirt cheap, solid, usually come with good quality components and allow an affordable canvas to try out artistic projects on. Wrenching is a relaxing hobby for me so I don't consider my labour to be a cost but rather a benefit.

The stuff I have used:




And before after/shots:

This is an 84 Diamondback I picked up for $20. The plan was to create an old quirky looking bespoke bike.


Since this pic it has lost the light and rack. I also changed it from 3x7 to 1x7.


This is a 60's era Woodwards Department store 2speed coaster. It's a long term project eventually to be turned into an early Harley Davidson motor bicycle type thing.


Since this pic it has lost the seat and bars to create a lower motorbike stance. I kept some parts of the old paint intact on the frame.


This is a 92 KHS I picked up for $50. The plan was to create a gravel bike.


Still working on it. Added stenciling as well as changing it from 3x7 to 2x7 making the large chain ring a bash guard.

If i had lugs i'd do wooden main tubes, using vinyl wrap.

Ah, I see someone has done bluing; I'd wondered if anyone had done that to a bike. I've done a little cold-bluing and find it difficult to get uniform results, even over small areas, but it looks great when it works. Utmost care needed to avoid contaminating the surface during and after cleaning.

Has anyone flocked a bike frame? I knew a guy who had that done to the tank and fenders of a motorcycle he was building for show. Comes in all colors, looks like velvet, and is incredibly tough. The area you wish to have covered is glued, then the fibers are applied electrostatically.
