Dropping in to say I'm one of the waylaid Kickstarter folks probably destined to not receive my Helix derailleur w/ UL upgrade. Wanted one to fit in the tiny trunk of the car I bought back during the Helix campaign--seemed like the ideal accessory. Still have the car, still have no bike that fits.
Not considering a Brompton Ti as I don't trust the tiny wheels to adequately handle our shabby pavement and for $2.5k more than my phantom Helix, the value is not there.
Anyway, best wishes to Helix owners and to-be owners. It seems like a terrific bike.
Cheers,
Rick
