Haha, I like all these adapter designs though my favourite was the Copenhagen Wheel[0]. I saw someone ride one near Mission and S Van Ness and loved it. Sleek device. This particular one in the OP is definitely built for safe societies, right? Definitely not for the North American market, haha!

Basically, the Copenhagen Wheel moved all the complexity of setting up a hub motor drive system - motor, battery, controller, sensors, computer - into the hub shell itself.

Which made it seem neat and clean, but meant it had serious reliability issues, couldn't handle wet conditions[], wasn't really repairable, and was expensive compared to more reliable alternatives with better battery life, etc.

[] The manufacturer apparently stated that "[...bad bearings] can occur when the Wheel is repeatedly exposed to wet conditions. Due to the nature of the problem, this cannot be repaired": https://forums.electricbikereview.com/threads/known-issues-p...

		Psst, you can escape an asterisk [*] with a backslash. Hub gears work quite well though don't they? In particular respect of being sealed and protected from the weather. Unclear why there's an opposite effect for this wheel.

It went on sale in the US before the EU. Did you even skim the wiki page you linked?

		I see. The way I spoke made it seem like I was talking about the Copenhagen wheel with the phrase “this particular one”. I was talking about the OP device. Obviously since Mission and SVN is in the US I would have assumed it was not the CW but I can see that I was unclear so I have clarified. The Copenhagen wheel is pretty integrated. This one is a thumb screw and off you run with a valuable battery. I wouldn’t buy it here and I bike every day in the city. People who don’t bicycle in North America won’t quite get it. It’s not exactly Taiwan. Theft is rampant and it’s societally sanctioned in most major cities.
