Assuming you’ve got the same head tube angle as the bmx, I guess being able to ride your cycle truck with no hands depends on whether you could ride the original bmx no handed with that wheel and tyre. If you never had the original bike, you might never know.
Can you do a plot to see where the contact patch is on the ground? Draw a line through the head tube centre and it should pass through the contact patch +/- not too much. If it’s way forward or backward of that, the handling will suffer.

Frame was originally a mtb frame. All the green areas are the new metal I put in. I never had the frame built up before doing the modifications.
Edit: I think bmx frames would, at least nowadays, have slightly steeper head angles, more like 74-76deg but that’s not much eh?
I’ll measure it up and plot it out on the computer and see where things are.

So I got my cycletruck put together last night and took it out for its first ride today. All good except I'm getting a shimmy when I take my hands off the bars. Anyone else got a cycletruck and that suffers this?
I had a bit of weight on the front of it, not sure if that's got anything to do with it. Meant to try it unloaded after I got home but forgot.
Headtube angle on my drawing is 72deg (will check what it actually came out to tomorrow) and fork is a bmx one with steerer extended so has about 30mm rake. That sound like a recipe for disaster to anyone?
