I'm from Indonesia. Seen lots of trifolds and pikes on the street these days
Basicly these two local bicycle brands caters low end/entry level bicycles. The only local brand for middle/high end market is Polygon for now
United is older, bigger brand, while Element is newer but they go head to head in the market
Trifold came out first, in my opinion, better quality. Pikes comes later, but they fold exactly like brompton
Pikes struggles a little bit at first. A lot of faulty parts such as tensioner etc. But they're getting better. I think the 2019 Pikes is really good
Trifold fold to the left (brompton and pikes to the right), so the chain is exposed. But they have internal cable routing, alloy frame
As for the official websites, usually if their target market at the lower end, they don't really bother to update the website. Probably since their customers prefers to go to LBS and ask questions over there
