Really nice job! Did you have a QR seatpost binder bolt welded to a threaded rod? Or did you fashion a cam for a QR lever on a long threaded rod? Or...?

Hold on a sec. Now that I look at it again, seems like the stem in the 1st picture showing the whole bike is not the same as the ones in the other thread showing the stem in pieces. The diameter looks constant in the first pic, I mean not necked in where it inserts into the fork steerer, and the QR lever is different. Looks like a QR stem from a Pacific Reach bike actually. Whutsupwidat?

The stem in the picture is the old setup. Had two new ones made last autumn. One is already installed on this one:
the longtail is waiting for a new headset before I install it, but both are ready made.

Actually the present stem and the new stem is much the same. Both are old seatposts from these bikes, used upside down. Present setup is held in place with a clamp abowe the headset (since not much is inserted into the fork). There is a star nut in the fork like on a ahead setup and a long DIY threaded rod and quick release at the top. Ok for riding, but slow to dismantel.

New stem is same seatpost but with a piece of a quil stem welded to the "seat clamp spot". Long DIY threaded rod innside to a quick release (or maybe the plastic nut since it is lighter) at the top. No star nut, but the same top as you find on a ahead setup.

The two new stems on the bikes are not the same size. The one on the black folder are the right size (and steel, so sprayed with silver rattlecan). The one for the longtail is chrome and slightly smaller. I use a shim made from a soda can between ahead stem and the (seatpost) stem.

You can see both the new stems in one of the pictures, one is welded the other one is not. This is to show what pieces it is made of. Pictures of stems are a bit old. Should get some newer pictures taken.

Thank you sixty, you are sweet .

It is far from finished, but I wanted to start posting since there has been quite a lot of "talk" about longtail 20" folders, both is C&V and Utility.

What I like about it is that it is detatchable, so I can easily carry it on a normal car rear rack. It is shorter than a normal longtail, and therefor easyer to take on bus or train also, put inside a flat or an elevator. It is big enough for me+ dog+shopping. Small wheels are strong wheels.

As you can see I could not make up my mind about colour. The black front is one piece, and the red plus black in the rear is one piece. No cabels holding it together when used as a longtail (shifter on the seatpost, coaster brake rear, front brake on the front piece). I`ll deal with the colour when I am happy with the setup and all welding is done. Also this way it is easyer to understand how it is built.
