I like the idea of Pinion crank gearing. I don't like it enough to sign up for a frame that's 100% useless without a Pinion gearbox. So no thanks.
Same goes for Bosch, Shimano Steps, Bafang M500/600, Nicolai G-Boxx, and any other system using a frame that can't be used at all without that one specific system's components. Once they have you hostage, you're kinda screwed whether or not they stay in business.
