Braced with Aluminum legs from walker


It’s actually well braced with aluminum tubes salvaged from an old walker (it belonged to my grandmother). U-bolts on each fork, there’s a reinforcement inside the end of each tube, slightly flattened to fit the threads.
This arrangement prevents the handlebars from moving forward if I brake hard. It’s a lot stronger than you think, those milk crates can stand a mans weight standing on them.

BTW, I got the handlebars shims on another bike right now. I bought two sets of these ape-hangers…

Here's the pic. You can see the Coke shims on each side.

This is far and away the best thing about bicycles and cycling I've read in a looong time! As a cowboy home mechanic I'm finally vindicated!

I want you to make the Gods of Pedaling a solemn promise: 'I will do nothing that mechanically alters the frame and fork of this bicycle"
Everything else is fair game.
I'm pretty sure you know what you have there, but just remember, there will never be another one made, It's a moment in time.
Don't let it get away either, you will regret it. I do.

That being said, is the crate a stressed member or is it framed? You gave me a couple of ideas, lol. :D

Underside of milk crate

There may or may not be stress on the milk crate. If I stop suddenly, my upper body momentum may push the high-rise handlebars forward, but this is stopped by the aluminum bars holding up the front of the crate.
They have tie-wire holding them so they don’t drop out.
