Metal rims on the Strida 5 allow higher air pressure and thus lower resistance when riding although it feels more in hands cause every small gravel makes the bike vibrate?

Bad fakes can go either way. Some will like the concept and buy the real thing and others without testing the real thing get disappointed using the faked one and think the real one only marginally better.

Where I live the real Strida 3.2 failed to click the wheels together so it failed to roll easily in front of me cause the wheels wanted to go ways on their own. It was impossible to click them together. I put much effort into forcing them together but had to give up. So despite being original something didn't fit. Maybe the persons behind the scene in the bike shop was new to it cause the bike is not a regular bike and they maybe didn't follow instructions that well.

To me it is a moral issue too. Ideally one should not fall for buying fakes. Apart from injury due to the fake breaks down. We have had several Mountain bikes that breaks at the welded seams and that is very dangerous at high speed. So the warning to not buy fakes is true.

But if something is 6 times cheaper that could mean the original is priced too high.

Brompton here is very costly. So had Flamingo been easily avalable so I could test ride it and look at quality me maybe would have bought one.

The SmartBike me bought had a three times higher price here compared to if I had lived in England.
I could be wrong but to me it looks like a HandyBike rip off. HandyBike being the original and SmartBike the fake. There is so little that is different so I fail to see SmartBike as an original construct. To me it is a fake and a very bad one at that. Bandbrake extremely bad at breaking.
