Bike with seat but not seatpost
Hi, I just bought a bike at a flea market, I thought that the height was good, but I realized that I need the seat a bit higher. I took the seat off to put the seatpost up but it does not have one, the seat is screwed to the frame of the bike. Is there a way to fix this?
thanks,
thanks,

If the bike were a typical design one would get a seat post that fit. But as your bike doesn't seem to be the usual and since we can't see it to understand it we have little to offer yet. Can you help us help you? Better description, photos? Andy

I think that a picture would be necessary to be able to tell what sort of setup this is. We don't even have any information about what sort of bike it is. You should not have to remove a saddle in order to raise it

Recumbent? Make and model should be painted somewhere.
That would help people who want to help.

you cut it to size
the seat clamp and the seat tube are separate. to adjust the sadfle height you cut the seat tube to height.

Probably one of the old/cheap 'pillar' type where the seat rail clamp is separate from the post itself. Loosen the big bolt/nut and the seat pulls off, but the post is still secured to the frame.
Could be even weirder and have one of the quill-type posts that doesn't have a clamp bolt in the frame.

I bet he has something like this...
there is the seat tube and there's a seat mast that clamps onto the seat tube. you cut the seat tube to size. now, if you don't have enough seat tube, your goose is cooked.

and not some custom aerofoil shape
what's the point in doing it seat-mast style instead of a normal clamp and post?

I don't know...
aesthetics, maybe, because the seat tube is indeed in the shape of an aerofoil shape...people are always trying to knock down others. Is your own bicycle the epitome of design and technical rationality?

I wonder if the OP means that the bike has been cobbled together by running a bolt through the parts of the seat clamp, and the holes for the normal seatpost clamp bolt, thus eliminating the seatpost.

Just a hunch, but I didn't read xenologer's post as an intent to 'knock anyone down'. Maybe a little puzzled by the aesthetics-over-practicality approach, but not in an insulting way.

You guys don't speak mini velo, do you?
Mini velos ain't meant for speed or rough terrain, but aesthetics and uniqueness play a role.
