Hello OutnBack, welcome to the forum!

The forum has had a good many threads on Sekai bicycles in which the various models are discussed.

There is also information on marque history. You can pull these up with the aid of the search function.

Tip -

something wonky is going on in the front (photo nr. 4). either the front wheel is misdished or the fork is out of alignment. this will affect tracking/steering.

Or it could be simply that the wheel is not seated fully in the dropouts. Letís hope so!

That's a good value. Honest product. Looks like we are near to the 1976 time here. Is this 25" (nominal) a good size for you?

I'm 6'2", so the 25" frame might be close to being to large for me.

...a Sekai 2400 in solid original shape (assuming the wheel thing turns out to be just a poorly seated wheel in the fork ends), is a pretty good deal.

Solid product from the glory days of Japanese sourcing by an American company with a reputation for good specs, and touring geometry add up to a very practical and functional bicycle. I think in some of the years they were made from "lesser" frame tubing (in that it was heavier), but for this type of bicycle, that's no disadvantage. I'm 6'2'', and I can't comfortably manage a 25" frame. But I have short legs and a longer torso.

With "average"/"typical" proportions it should be just about right.

One minor variable which can slightly affect standover height is the height of the bottom bracket shell. On a machine such as this one would expect a shell height of ~10 3/4" or 10 7/8". Sometimes on the smallest of japanese frames the manufacturers achieve the small nominal size by raising the shell height to as much as 12" or more.

Does the head tube look too upright? I see a little rust under the lower main tube's insertion point into lower head lug. I would look very carefully for evidence of a head-on crash that bent the head tube, maybe also the fork.

Its also more possible and more likely that those cheap tires simply did not centre correctly when mounted on the rims. If the tire is a bit too small the bead may not be stretched out and may not lying symmetrically all the way around the rim. I have had this more than once with cheap new tires. Spin it and if the centre of the tire wobbles side to side you may need to over-inflate it to get it to pop into proper position: otherwise you will feel it bob each time it rotates to the low side....

I would say It's worth $175-200 and a nice bike for a larger rider. As for the front wheel issue it's hard to tell from the pics but the fork and wheel look strait so it is very likely it's just miss seated aligned in the dropouts indicating a clueless seller so I would off $100-125 if it's your size.
