The mechanism works because the "head" of the bolt is in the middle. It's a double ended bolt basically. The nut on the end that goes into the bike only attaches it to the bike, and it's tightness has no impact on the functioning of the brake, other than stopping the bolt rotating.

There are 2 nuts at the other end. The inner one needs to be loose, to allow the brake leavers to rotate freely, and the outer one is tightened against the loose one to keep it in place.

I'll try making a diagram when I get home.

The nut at the back of the fork is what should be holding the assembly in place. Maybe try making that nut tighter?

I do think copyright should still exist, but with fair use being significantly expanded, maybe something like CC BY-NC?.

The bit about being non-transferable and owned by the individual creator is exactly what I was thinking.

Also: fuck patents.

I have that bike too!! branded "stratton", but has the exact same frame. I've been gradually repairing it, and it's currently in my living room (workshop) waiting for parts (incl. new winding wire for the dynamo). It's 50% brown paint and 50% rust, and the tyres (presumably original) are splitting apart, but I don't plan on fixing anything that still works. There is just too much rust for me to feasibly remove or paint over. Will try to add a photo tomorrow.

Edit (The saddle is temporary, I still plan on fixing the original):

My laptop's screen died, and in taking it apart to see if it was reparable/replaceable, I tore off the antenna socket from the WiFi card. The WiFi card can be easily replaced, but there is still a bit of it stuck in the end of the antenna cable that hasn't come out yet... I'm not sure what the solution is yet (I might try soldering the cable to the card directly, if I decide the cable is a lost cause anyway).

Also my phone had it's last breath last week, so now I'm using a 20 yr old laptop, and a 10 yr old phone.

Could you maybe attach one of these to the scooter? I have no idea how scooter trailers connect.

Yes, seaweed is good, and widely used where I live (Also not an expert though). It's best to let the rain wash some of the salt away first though.

I live on one of the smaller Orkney islands, and the difficulty of getting here filters out many types of tourists found on Mainland (notably those with vehicles). Shetland is a little harder to get to than Orkney though.

I believe some motorised trailers use a sensor in the tow bar to detect if the tow bar is under tension or compression. Under tension, increase the throttle, under compression, decrease the throttle. They also might have brakes which could be applied under strong compression.

I've never used one myself though.

I don't entirely see the point of living on an island if you can just drive off it any time. (As someone who lives on an island).

This article reads like an AI(?) summary of a reddit thread itself though.

Cuddle my cats.
