cool. good job, it looks solid.

Looks well costructed, but the brake pedel should be redisigned to provide more leverage.
A mechanical brake operates on the same principle as a bolt cutter "multiplied leverage" on the stock bike the pedal is say, 12 inches long and the lever attached that pulls the rod is 3 inches. 1 pound of pressure on the pedal results into 4 pounds of pull on the brake rod.
With thjs set-up, the rod is attached just under the pedal resulting in almost no mechanical advantage, To get the same amount of pressure at the brake shoes you would have to exert almost 4 times more pressure at the pedal.
By designing in more leverage into the pedal you are rewarded with a much better rear brake.

Would bee fine if you will send a file to me.
Dxf or if you have 3D you can send it as stepfile.

Thank.

Here's the "basically" finished bike...
