12 Inch Bike Geometry Records: Keep Wheelbase, Saddle and Bar Heights Separate
12 inch bike geometry records describe several different distances and angles. The wheel-size label cannot stand in for all of them. On the woom GO 1, keeping the printed headings beside the numbers also exposes a saddle-height question that the product page does not consistently answer.
12 inch bike geometry records need their headings
The saved UK GO 1 geometry table lists a 555 mm wheelbase and a 294 mm horizontal top-tube length. They are separately labelled dimensions. Its cockpit or handlebar height is 474 mm, while the steering and seat-tube angles are 68 and 72 degrees respectively.
Write each heading next to its value instead of collecting an unlabelled string of numbers. A wheelbase is not a saddle height, and a top-tube entry is not a standover measurement. The cited record does not publish a conversion that would make those quantities interchangeable.

Keep regional units with the original record
The UK table gives a saddle-height interval of 258–353 mm. The current US geometry separately prints 10.2–13.9 inches. These are manufacturer table entries attached to their regional pages, not measurements taken from the bicycle shown in the photograph.
The UK source was captured on 18 October 2026 and reread for this article; the US page was captured on 5 November. Retaining those dates makes the comparison traceable without pretending that the archived UK page was newly downloaded.
Preserve the unanswered saddle-height discrepancy
A manufacturer reply beneath the product page says the saddle can be raised to 365 mm. That differs from the geometry table's 353 mm maximum. The reply is a published response to a customer, not a corrected model-specific geometry sheet that resolves the difference.
The listing calls this product woom GO 1 US - Balance bike - 12 inches - 1.5 – 3.5 Years - powder pink. Use the named GO 1 catalogue example when asking support which geometry and adjustment instructions apply to the delivered bicycle. Quote the table and reply separately. Do not average their values, silently select the larger figure or create an unofficial limit.
This enquiry concerns the meaning and consistency of published measurements. It does not choose between GO 1 and GO 1 PLUS, prescribe a saddle position or certify that a particular rider fits. A properly labelled record is the starting point for obtaining the missing clarification.
Geometry-record FAQ
Does twelve inches describe the wheelbase?
No. The UK table gives wheel size and wheelbase as different entries.
Does this article resolve 353 mm versus 365 mm?
No. The conflicting statements remain separate and require applicable manufacturer clarification.
Can top-tube length be relabelled as standover?
No. That would substitute one named dimension for another that is not supplied.
