I've been riding a Tern Link P9 for a month or two, commuting 6 miles each way 5 days a week and dragging into onto trains and tubes. It's a lovely bike to ride and that's where I feel most satisfied with it. There's an issue with the chain ring protector which means that the chain does occasionally drop when switching between 8th and 9th gear at speed or when you hit a bump. It can be rectified by pushing the protector closer to the chain (it's a common problem). That's the only issue I've had with the ride. Even the saddle has become comfortable after breaking it in.
I feel less satisfied when I'm lugging it around on a train. The magnetics that hold the fold together are too weak and the bike can swing open (I've spoken to Tern about this and they're producing better magnetics that will be available next year), though you can hold it against yourself to prevent this. It's possible to wheel it around, but as the handlebar stem folds outside of the bike, it allows the front wheel to turn, pulling the fold apart or pushing the tire against the frame meaning you have to be a little more careful compared to my friend's Dahon Mu Uno (which has much better magnetics, I might add). The fold is compact enough to stick into a corner at work or on the train and not bother anyone though.
That's my honest full opinion and I don't mean it to sound negative. I'm very pleased with it but I feel that I'll get something with a more compact fold next time as long as it rides as well as the Link P9. Lots of people comment on how good it looks and it's generally a lovely bike, however, if the ride on the Mezzo is good then I'm probably swerve towards that. The fold looks great!
If you've got any more questions about this particular bike (I'm not very experienced with other folders unfortunately) then feel free to ask.
