I saw both the mu uno and the tern link uno in the same store and it's quite a hard call on what to pick. They both felt very stiff when I sat on them and tried to flex the handlebars and frame. Tern was $750 CDN and Dahon was $650 CDN. But then I started to compare the little details between the bikes at the store.
Tern had the beefy clamp similar to the speed's vice style clamp but a bigger self locking handle which snaps shut very cleanly and cannot be opened accidentally unless you hold a spring loaded switch when pulling, while the dahon has this newer V clamp technology which to me is a cross between their vice clamp which pulls a C clamp on the other side to lock the frame like the brompton but without the screw thingy tightening it. This one also has a mini safety device to keep you from accidentally kicking the lever open while riding.
Folding the frame in half I felt a bit of resistance on the dahon, might need some oil in there to loosen it up but there will still be a bit of friction like my wifes dahon jack no matter what I do. The Tern when I folded it felt like opening or closing a well oiled bedroom door, I was kinda surprised how it had almost zero resistance when folding but when clamped shut there was zero play in the hinge. They really did improve upon their latches!
The dahon had better tires with schwalbe marathons while the tern had schwalbe citizens.
both bikes had the plastic chain cover thingamajig.
dahon has these really nice machined kinetix crackset while the tern had some no name that looked like a crank on any other typical bike.
dahon has nicer looking wheels than the tern. (I know nothing about the wheels so that's a very qualitative comment)
This point bugged me the most:
dahon seatpost comes with the built in frame pump, tern is just a seat post which will cost extra to get a seatpost pump.
This was the impression I got both bikes messing around there for 30 minutes which the store employees thought I was a bit obessive on single speeds when around me sat bike fridays and multi geared dahons and terns. They both ride very well and are very stiff cause of the one piece handlebar on the dahon and the beefy steering clamp on the tern. Felt stiffer than the brompton I tested in a store also (m handlebar version). Don't take this as a real review but just the initial impressions of someone messing around with the bike when they see it in the store and spun around the block with it. I thought about getting one of these as a daily commuter but neither of them wheel around as easily as my strida. I daily commute with mine and sometimes the elevator is a tight squeeze and my stick on wheels gets me everywhere with a clean and fast fold.
Oooo almost forgot, the tern at this store had fenders already while the dahon didn't.
here's a some bike porn shot :) was mmsing to another bike nut that I got to see one in the metal!
