Sun Race 3-speed gear box for Strida
Sounds interesting: No shifter or cable. Less rotational weight. Lighter than gear hub. I wonder if Sun Race would market this to other bike manufacturers (CarryMe perhaps)? Or even make a Sturmey Archer version?

I'm finally happy the Strida managed to strike a deal to get gears for their folders. However, I'm not too pleased it's an auto-shifting design. Trek not long ago made the Lime 3 speed bikes that were shifted automatically controlled by the front hub. It was less than attractive and "cracked" if you did the shifting wrong which was not difficult to do! You had to be very gentle when shifting with your legs or the tranmission would sound like it's breaking under load.
I do like the three speed hub and have two bikes. However, being able to control the shift is important in not damaging the hub.

Very interesting. I was thinking about a FSA Patterson 2 speed internal gear crankset on the Dahon Jifo (possibly EEZZ/Metro if launched). The rear hub is very narrow so adding gears and internal gear hubs off shelf seems impossible. If these Sun gear boxes were available it would make the frankenhon even more attractive.
That is of course if these gear boxes are reliable and not super draggy.
*EDIT -reading up on Strida the bb shell is quite large for the eccentric adjustment. This gear box seems to consume that large shell which splashes a little water on my pervious thought.

Blackstridaaustria has filed a test ride report from Eurobike:

And yes, they put the Sturmey Archer logo on the gear box.

Sturmey Archer hubs have not received glowing reports lately, specifically the 2-speed kickback hub has been the subject of severe criticism. This bottom bracket will receive much bigger torque than a rear hub gets, so I hope they designed it strong enough for the job.

So when I read that this new Strida hub is newly developed, and lighter than the old venerable 3-speed to boot, I can't help but wonder... more torque, but less material...?
