It makes you wonder if that number of new offerings isn't getting a bit ahead of actual growth and affecting the sales of existing players.

The number of new offerings and firms getting into ebikes this year seemed to really accelerate.

It will be interesting to see if some numbers are gathered by a 3rd party entity to show what the growth was like for 2019 here in the US. By 2017 Bafang had gone on to produce the BBS02, BBSHD, and various OEM mid-drives, on top of their hub motor business, the fine was a drop in the ocean of their profits, Sunstar meanwhile withdrew from the mid-drive kit motor market a week before the final court decision was announced. I am not a lawyer but various threads on Endless Sphere report a history of patent infringement between the two companies, a 2008 Bafang patent copied a 2002 Sunstar European patent, and the later 2013 Bafang BBS01 patent copied the 2010 Sunstar S03 patent, albeit without the torque sensor, which led Sunstar to initiate the court action. Sunstar filed suit against Bafang in a German Court in November 2014 and the case was settled in April 2017 in Sunstar's favor with Bafang fined 500,000 euros.

Grin recently came out with a video showing how to bypass the Bionx controller and keep using the direct drive motor with a generic controller & battery, the downside being you would lose the Bionx axle torque sensor and need to buy a bottom bracket torque sensor, but I imagine with these hacks or paying a company to re-cell an exhausted battery pack Bionx motors will be around for years as there are fewer moving parts in a DD motor, and as Justin points out in the video Bionx DD motors have less rolling resistance than typical generic DD motors.
