I'd never buy such a product myself, highly proprietary, environmentally damaging due to short lifespan and being uneconomic to repair fairly quickly. We need to buy bikes that have an easy 5 year life and perhaps last 10-15 years ideally. I wonder how much the founders paid themselves and how many millions they have taken out of the business. It sounds like the proprietary nature of the bike led to poor reliability and high warranty claims which could be a huge factor.
I was looking at used ebikes on ebay and this came up;

Starting the auction at £700 for what is a paperweight faulty ebike. It's based around a Bionx hub motor which was poor quality and highly proprietary and what looks like a huge number of other proprietary parts. £700 is enough to buy a decent entry level bicycle and good ebike kit. Bionx went out of business a few years ago with a lot of unhappy customers.
There is no reason why ebikes can't be designed to be easily and cheaply repaired using standard and non-proprietary parts.
We need to move away from high cost throwaway garbage products.
