My dahon boardwalk D8 has paint peeling at the hinge.
Is this normal?
The hinge is easy to open but tight to fold

Paint peeling is never normal. Have you been riding in the rain allot? Even if there are pin points in the paint or perhaps when you close the hinge the paint got a little chipped, water will enter and wallah the paint will start to peel. I ask about the paint being chipped while closing because you mentioned it was tight to close, perhaps too tight and needed adjusting. None of this is normal and should be made known to the dealer and manufacturer.

i wouldnt worry oo much, make sure the latch is adjusted correctly and put a little dab of grease on those contact points ...

It is dry n haze season here so rain water theory is off.
My theory is that there more stress on top on the hinge than the bottom.
Iam over 90kg and the weight limit is 105kg.
I like to sprint up a small hill and pulled the handle bar toward my body for leverage.
But i never ride standing when sprinting.
Less than a month and less than 50km on this bike

The paint wore through on the contact areas of my Dahon's frame quite quickly. I think the process would have occurred more slowly if I'd tightened the clamp slightly to reduce any movement, but I think with this type of hinge the paint does tend to abrade. Though I can't see much from your photo.

There's your problem. If there isn't any rust set in, get some touch up paint and have the clamp adjusted properly.

Can we use tern hinge adjustment videos as a guideline on how tight the latch should be?

its not peeling its percussion. the riding the bike caused that .

its at least closing tightly, at the contact point .. how about a piece of rubber there?

From memory I believe they're the same.

i refer to owner's manual to tighten it.
