There's a couple of these on a trail near me, and although the bollards can just be pulled out of the ground, they used to be padlocked.
Some people who use cargo bikes to shop couldn't get through, so the city removed the locks.
The bollards are still there, but if you need to get through you can just lift it out, mosey on by, and then replace it. The middle one is made out of hollow aluminum I think, so it's a lot lighter than the other solid steel ones. You can still lift those out, just not one handed.
Up until then, the cargo bikes were just hopping off the trail and cycling along next to the trail on the other side of the fence, which was only about 200-300ft long on either side of the bollards.
The OG most wanted is hands down my favorite of all time.
I dropped $40 just to play on my Xbox around 10 years ago.
I'd buy it again if I didn't already have it installed.
