I came across this one https://bafang-e.com/en/products/motors/hr-series/h700/. Seems to have two gears(probably just changing rotation direction to switch between high and low gear).
It should be a good solution to give power limited hub motors a good climbing ability. I couldn't find any first hand information on the web, does anyone own or have ridden a bike with this system?
