Dahon GB-1 folding gravel bike (650B/27.5")
Drop bars, disc brakes, full size wheels, not bad!

Good find; that thing is pretty cool. I love fat tires and disc brakes. I'm curious if the geometry is similar to other gravel bikes, but seems too new to find info on.

Seems weird having front and rear shifters but only the rear shifter is used. Better to have a single dedicated rear shifter I would of thought and standard brake levers. Nice looking bike though.

Likely cheaper to just buy the pair, as is. once its in your house you can see what you might get when you sell the left lever on its own.

Old wine in a new fad bottle
this bike is essentially a Cadenza, offered by Dahon for about a decade now, with drop bars and 650b tires, seeking shamelessly to jump on the 'gravel bike' and 27.5"-wheel bandwagons. nothing new here.

Is there nothing new here, or is it a Cadenza updated to dropbars and 27.5 wheels? That sounds like a new model to me.

takes very little to impress you, it seems. wow, what a heck of a factory upgrade! it's not like no Cadenza owner could not have done that themselves a decade ago. Say I slap drop bars and 451 wheels (ISO584/27.5" is closer to ISO559/26" than ISO451 is to ISO406) on my Dash, is it a new model? No, it's a Dash with 451 wheels and dropbars. Swap the Birdy's 355 wheels for 406 (a bigger jump than 559 to 584), is it still a Birdy? Yes. Same thing here.

Dahon is offering a new design frame in the just announced NuWave family of bikes to serve the needs of a different segment of the humans of the world and according to some of the posters on Folding Bikes, that sucks, too.

...and D4D handlebar stem.
Look, there is nothing ostensibly wrong or bad with this new Cadenza. As one of the very, very few active users on this forum who actually owns and uses a LockJaw hinge bike, I've considered getting a Cadenza. It's just that you are getting hoodwinked if you think this bike is something more than a souped-up Cadenza.

I stand corrected.
This from Th0r on the new bike...
there is s much different on this frame its not even close. First the frame is hydroformed and much stronger to keep up with the natur of adventure gravel touring. 2 width for tire clearance up to 42 mm wide tires. Different angles to keep you in control during sketchy parts. The Lockjaw is very different as well, stronger and not dependent on a cam. The flatpack adjustable stem of course. Bottom bracket clearance is optimized. I am probably forgetting some stuff even. And again this is a proto and will receive small changes for production, like more attachment point for carrier and fenders.Not to forget that it will get a whole slew of other components to make it usefull for the intended use.

Another prototype of the GB-1. Lots of changes since the introduction at Sea Otter:
-thru axles
-more traditional looking stem
-no more little reinforcing seat tube strut
Really hope the listed weight (20kg) is a mistake.
