I'd be interested in buying a Reach frameset instead of a Reach STD bike if I could build a bike with an internal-gear hub (Nexus or Alfine) , as I have been spoiled by my Birdy City.
As the rear folding seems to be the same as the Birdy, I believe it should be doable : am I mistaken ?
Would anybody have any recommendation on how to do it ?

Thanks !
