I'm not so sure about 'massive' problems
@EULITTLB ; however, first releases of most ebikes have some issues that need tweaking or in some cases, everyone's patience until the next production run arrives to solve the problem. Issues that can be problematic if there is no professional help to handle them. Some companies choose to just throw parts to the customer in an attempt to solve a problem; however, many frustrated folks have wound up in my shop and other LBS when the bike owner never got a working solution from a phone or internet customer service rep. We also get updates or dealer bulletins from some manufacturers with critical technical information that may require action for new floor stock or adjustments for product already sold. And most manufacturers get an earful from us, their dealers, pretty fast if there's a problem that repeatedly crops up! With respect to Sonder's bike none of us know exactly how he plans to support his bike-- consider different languages, time zones, etc. In comparison, if I buy 1 Cree Li headlight on Alibaba through their 'Trade Assurance' program or a charger via DHGate, the specifics of returns and warranty with the Asian supplier is clearly spelled out before the purchase and there is a centralized point to file complaints about a product or shipping, so some level of secure transaction. It remains to be seen how this will be handled with the little yellow bike.
