Hi guys, new forum member, first post outwith the intro section, so hope i have chosen the correct section to post this in!!

I am currently stripping my Moulton Mini for a rebuild into a tongue in cheek, track/speed inspired machine. Not one for the purists, but she is missing most of the front suspension parts and has been very badly painted at some point.

As per title, the bike in question is a Moulton Mini, which was buil 7/8's of the full size version to allow for children and the average height female from that era to ride them. So the bike has 14" wheels as opposed to the usual (for a Moulton of that era) 16" wheels. Along with that, everything else is smaller also & therein lies my problem.

The original bar and stem is a one-piece affair, which I'm looking to replace. From what I can tell, the bike runs 1" threaded forks. However, the quill of the original stem only measures with an external diameter of 19mm. Not a size I can seem to find a replacement stem for to allow fitment of another bar.

Does anyone on the site have any experience of this, or even better, a solution to my problem?

Any help or information would be greatfully received.

Thanks for reading.

Paul.

I assume the stem diameter is nominally 3/4 inch and is probably not such a rare item. Have you looked at tricycles and juvenile bikes?

I had really just been searching for a replacement stem by size and couldn't really come up with anything searcing for 19mm or 3/4 inch.

Interesting... I was not aware that the Mini used a smaller quill stem than the standard Moulton.

One could always build a stem but that is a little pricier and more labour intensive than finding one.

I didn't think it would be anything too out of the ordinary either. As for building a stem, unfortunately I am quite limited to what I have access to tool wise. Kitchen & back yard cycle mechanic I'm afraid. So, not really sure what I'm going to do here. Seem to have hit a bit of a brick wall with my plans.
