Sunday Blueprint Complete BMX

What the checker saysnot checked

No fit check runs on a complete bike, and we will not pretend one does. A complete bike does not fill a slot in the builder, so the checker has no counterpart to compare it against and has never produced a single sentence about one.

Open it in the builder

The checker compares the dimensions listed in what we check, and what we don’t. “No conflicts found” means no conflict among those dimensions — not a guarantee that a build works. Errors mean it won’t fit; warnings mean it works but check; infos are notes.

4 further fields the checker looks for are not published by Sunday, so we leave them blank rather than estimate them, and those 4 checks stay silent on this complete bmx. They are size class, seat system, front brake mount and rear brake mount. Each is recorded as “not stated by the maker (not checked)”.
