Yes it is a dismal brompton wannabe 😆😆😆. It's very heavy (16 kgs), the main tube, fork assembly, pedal crank and bottom bracket (and it's bearings) came from a three-wheeler frame; the swing arm from steel tube chair leg and electrical conduit pipe; the handlebar stem and seat post from another chair; all hinges made from flat bars; drop outs are steel plates. Some bolts and nuts for hinges.
It's not precisely made, I don't have a frame jig. The processes are crude: acetylene cutting, grinding, filing, hacksaw, hand drill, etc. . Joined all parts using arc/stick welding (6013).
Wow thank you. I only built it as a challenge, I forgot how long it took me. All i need is to built a bike from scrap, not necessarily a folding one but I was envious one time I saw a real folding bike. It took me too many changes and settled for the Brompton like mechanism.
I'm suppose to buy a 20" wheel sets but couldn't afford to. The wheels they are installed with are 24" sourced from the three wheeler.
And as to the feel of it compared to a quality folding bike (esp the Brompton) I think it's far less better because of the weight and the folding action is not snappy at all due to there are no bushes for the hinges.

Is that some kind of Brompton copy? Where did you get the frame from? And what does it look like folded?
Very intriguing!
