Does Echelon buy back bikes?

Excuse me, I've been hearing a lot about Echelon, their innovative approach to the cycling industry, and their commitment to sustainability. But one question has been lingering in my mind - does Echelon actually buy back their bikes? I understand that sustainability is a key part of their business model, but does this include a formal bike buyback program? If so, what are the terms and conditions? I'm particularly interested in knowing if they offer any incentives for customers to upgrade their bikes or recycle older models. Could you please elaborate on Echelon's bike buyback policy, if there is one? Thank you for your time.
