Tern Magnetix
I have three photos, and am not entirely certain that I'll be able to insert them where planned in the text.
My Dahon Speed P8 came with the "the plastic ball socket thingies", and based on advice here Iordered the Tern magnetix. I was a bit puzzled by what was in the mounting kit, as there didn't seem to be a secure way to mount the smaller magnet. Poking around, I found the first photo on the Tern site:
What I still don't comprehend is that this magnet appears intended to slide in and out under the spring's marginal control.
Is this the case?
I also found a photo on a Euro site, showing what appears to be an alternate (earlier?) version.
Looking further, I found this site: https://tinyurl.com/zmsca3e
which has the last photo:
showing the Tern small magnet piece at a very distorted angle. This fellow didn't like the Tern magnetix, and switched to the Dahon socket system - just the reverse of what I want to do.
==>> Did he install it incorrectly, and if not - how do you keep the right-hand piece perpendicular with the mounting braze-on?
==>> How do you install the Tern E-clip so that it doesn't go flying? They only include one, and I've had similar parts disappear and/or break in the past.

I believe Thor has info on these.
I think he has posted before on the topic of fitting Magnetix on other bikes.

Well - Dahon dropped them and went back to the magnets, so maybe you should ask them.

I have no experience installing the Tern part on a Dahon.
Perhaps you should use the Dahon part rather than the Tern part.
I think ThorUSA has both available.
This looks like the version that has been on all of my Dahons.
This may be because something is preventing the bike from being folded so that the magnet and the metal plate line up better.
In the picture, the "right-hand piece" appears to me to be the magnet assembly. The spring around the bolt holding the magnet provides a small bit of flexibility. The circular plate attached to the front fork is mounted at an offset to allow some flexibility in the location of the plate.
Sorry, but I can't help you with this one.

its a little tricky to get the circlip on there as the spring wasnts to pull the rod away, but its not impossible either. Havent seen a circlip loosen after it has been installed
main difference is that the tern is much stronger magnet

I may need to order a set of Tern magnets from you. My Dahon Speed P8 plastic thingy is cracked, and the magnets will be a huge improvement.

I have 2 Dahon Speed bikes, and 1 has the magnet, and the other has that annoying clip. Here's a picture of both,... 1 is the Speed P8 in red, and the other is my custom Speed 3i (a former Speed Uno/Duo).
