Would you use standard front wheel from a CB on a sidecar? I feel the 15mm axle is not strong enough to be attached on one side only, I would install bigger bearings in the wheel (20x42x12) and use 20mm axle on a DIY swingarm such as the one on the picture.
I am aware of the advantage of a trailer wheel on the sidecar, but no thank you, I want a spoked wheel.
What do you think?
