Dahon Folded Dimensions: Read the Whole Storage Triple
Dahon folded dimensions should be read as a complete three-number reference for a named model. The current USA K9 page lists 28 × 16 × 20 inches, K3 lists 25.6 × 11 × 20.9 inches, and Mariner D8 II lists 32.7 × 13.8 × 26.4 inches. Wheel size alone cannot answer the storage question.
Compare Dahon folded dimensions without inventing axis names
The selected tables give triples, but do not establish a shared labelled length-width-height convention. Copying them into a comparison chart with newly assigned axes could create certainty that the manufacturer pages do not supply. Keep the original sequence and units when arranging a demonstration.
Nor does a smaller wheel ensure that every quoted number will be smaller. K3's final entry is 20.9 inches, compared with K9's 20 inches. Mariner has a larger first and final entry than K9, but a smaller middle one. These comparisons show why one isolated number is an incomplete storage decision.
Start with the opening, then the resting place
A cupboard can have sufficient internal space yet an awkward doorway. A car can have a useful storage floor behind a differently shaped opening. Measure both the route into the space and the space itself, then have the identified folded bicycle demonstrated in its intended orientation.
Use a named bicycle for the demonstration
BestBicycle lists this model as Dahon K9 Bike — Silver-4-Bearing. That gives the seller a particular K9 listing to identify. Ask whether the manufacturer triple applies to the actual version and to any equipment you plan to fit. Optional fenders and racks are listed separately on the USA K9 page; their effect on the demonstrated package should be established rather than guessed.
The exhibition photograph is deliberately an unfolded view. It identifies the K9 model context but supplies no measured folded outline. Do not use the plinth, wheels or sign as a scale for reconstructing dimensions from the picture.
A storage size is not a travel permission
The generic DAHON owner's manual available online bears a 2012 copyright notice. Its transport section distinguishes a carry bag from a travel case and explicitly says the carry bag is not approved for airline check-in. That historical guidance does not establish a current operator's luggage allowance or approve every modern K9 bag.
Check your actual transport provider's requirements separately. For home storage, finish with a practical placement demonstration; for travel, also settle the packaging and acceptance questions. Those are different outcomes even when the same bicycle is involved.
FAQ
Can the triples be relabelled width-height-length?
Not from these sources alone. Ask which orientation the dimensions describe.
Does the photograph show the quoted folded package?
No. It shows an unfolded exhibition K9 and is not a measurement record.
Does matching a bag size establish airline acceptance?
No. The packaging and the operator's current requirements require their own checks.
Storage is part of DAHON’s wider transport idea, described in the brand introduction. After establishing the required package, revisit the Dahon topic for bicycle choices.
