No worries, any advice is good advice! Some great tips, but I am not sure what you mean by "Widening the mount to the axle shock area will triangulate the unit and eliminate flex". If you mean to use the shock and axle as mounts, then that what I am currently using. Both the rear axle bolt and the bottom shock bolt are used, so isn't that technically 2 mounting points?I don't want to wet blanket the license plate fender thing but when you ride that thing will be rattling and shaking with the slightest bumps.
When the frequency is right a sympathetic vibe will eventually snap it or cause rapid structural degradation cracks .
Widening the mount to the axle shock area will triangulate the unit and eliminate flex and adding a single tube to the other axle will reduce
flex on the other axis.
That may make it stiff enough for use basically now you have a 1 point mount by doing as suggested there will be 3.
You're going to need at least 3 , this is not a new idea,its been used successfully when properly designed and constructed.
First time you ride it you will see exactly what I'm saying. Nice Build keep it up .
Yup, that's the planIf you could, route the wires for the plate lights through the tubes for a cleaner look.

Sounds like you are a lot more knowledgeable concerning harmonics and frequencies than myself lol. In that case I will try the rubber mounting option first as that will give me the best base point to go from I believe.Just an a very rough guess but the unit should have a first harmonic resonance of less than .5 hz .
A nine inch steel rod suspended from 1 end has a first harmonic of point 9 Hz 2nd of 1.2 ect. up to the eighth of 6.4.
Being a dunce at math and not having the weight and wall thickness of the pipe pipe or the weight suspended at 1 end,
the damping of the 2 parallels not being the same length and other variables. Each factor affecting the harmonic frequency.
So you could be correct. With the use of rubber mounts.
I have been planning something similar after watching some videos of speedway bikes racing.
