Connecting motor to wheel

[Mickster]

Use whichever method you feel most comfortable with, and most importantly, safest.

Post #20, that is what I do.

Or you could make life easy and get a 13mm OD standoff. They will have a partly drilled threaded hole in them that could easily be drilled through to 8MM. Many electronics places sell them, but here is a company that makes them as an illustration of what I mean. https://lyntron.com/catalog/LynTron/B12

For a quick & dirty prototype you could shave a gluestick so it fits in the wheel then drill and 8mm hole through it & screw it on.
Rough but quick.

You need to make an adapter on the Lathe just like I did for the propeller on this go kart.

Ive only seen the couplers with up to 10mm bore unfortunatley. Have you actually seen an 8 to 13mm?

I recently bought several couplers from Skycraft surplus, which is a great store here in Orlando, that were multiple sizes. However, I had no difficulty in drilling out one end or the other, or even both ends, to allow it to fit as needed.
Give them a shot, good selection, cheap and been around for a long time. https://www.skycraftsurplus.com/

I'm looking for ideas on how I could connect the following wheel, to the motor shaft below? Ideally, I would like to connect it directly, without a belt.

Wheel : Bore size 13mm
Motor : 8mm shaft diam, 25mm shaft length, M4 thread.

Any ideas?

You may think that is a good idea but most motors have too much speed and not enough torque to directly drive a wheel that moves a car, a cart or whatever. Make sure your motor has enough torque for the job before you incest in the mechanical design effort.
