Boy, I sure hope you used oak for your framing wood members.
If not the holes in the pine/fir 2x2 will weaking it to much.
For a source of free white oak see if you can find/salvage a used
shipping skid. Most are made of good hard seasoned white oak
that make dandy strong framing members for a bike trailer.
