Upsizing 20" 1970's BMX bikes to cruisers

[rev106]

Goals are as follows:

1. Get more welding and frame fabrication practice

2. My materials are beginning to rust because I got stuck behind a hot rod project for a year and a half so use up my metal before it goes bad.

3. Use up some my parts that I am foolishly holing onto for some vintage cruiser frame that will never land in my lap.

4. Most importantly, get rad on the bikes I made.

I picked a Dave Shwerma Champion and a GarylittlejohnMurphy for my choices. I got the LJM bikes mostly finished first, they upsized ok, some of the look gets lost in upsizing unless you want to make a lowboy which I'm too tall for. Then I got into the Champion and that has to be the hardest bike to make! 10_ hours just in the dropouts. More to come...Enjoy the progress so far.....

Fixed the munched Poe

Fixed this Powerlite fork....mostly...

A few more glamor shots before I stuff it in a bush somewhere and mess it up.....

Awesome work, looking very good.
Hmm, is that a high flange coasterbrake?

Can I ask you Wizard: What tubing are you using? CroMo or mild steel (thick wall) or Reynolds, Columbus etcetera.

I found out that most stock cruisers have mild steel thick wall tubing.

Coaster brake is a NOS Shimano B type shell made in the 1970's with some guts from another normal b type hub. MX ones had MX stamped on the torsion arm.

16 gauge steel tubing, the white one was made 3/4 .049 4130 because I had just enough scraps left over from another project to do it. Schwinn made millions of bikes out of mild steel, I see no fault in using that material.

When will we the 26” Littlejohn?

Thanks for responding Paul, I see no issues either and I'm learning everyday
