I had my own ebike startup 2 years ago (Lectro). What killed it was the fact that large lithium battery packs were classified with hazmat status. This classification might have been spurred by the exploding hoverboards. Product shipping and liability became too high for profits. I would assume big box retailers have similar concerns. If the BMS in the battery had an issue, It was very difficult for the customer to ship back.
