you saw different information is because it has several different versions. like Curl on Kickstarter and Curl limited edition etc. I do not know if Dahon finalized the specifications. I think the wheel size all are the same 16 inches, actually It is a little bit bigger than normal 16 inch wheel size. maybe 16.5 inch. One of my customer bought one Curl and seems he is very happy with the quality and design. Personally, I think it is sturdier than Brompton, no too much difference on the folded size, in terms of the weight, I do not weigh both but I think Brompton is heavier as it is made of steel.
