       | Cool idea, I am surprised nobody came up with it sooner.

       | becoming pretty standard on all ebikes.

       | 
       | at least this adds a bit more granularity than the lame off/on
       | ebike e-brake switches that are most popular right now -- but it
       | sucks that it's at the loss of pad life rather than just sticking
       | a dirt cheap hall sensor on a lever somewhere and leaving the
       | pads for emergencies.
       | 
       | it is very clever, though.

       | Yesterday I was at a Bikeshop and was discouraged to buy a wheel

       | you loose your warranty from a supplier(not going to name).
       | 
       | So a big negative for me is the added complexity and dependency
       | on bike shops for simple things as changing wheels.

       | A fascinating idea, however it looks like the E-Bike industry has
       | "moved on" to mid-drive motors anyway in recent years, which have
       | the advantage of better weight distribution and being able to
       | more tidily integrate into frames. Mid-drives don't have the
       | missing freewheel problem, but due to this can't have
       | regenerative braking. And I don't know, I think I'd still prefer
       | two redundant mechanical braking systems rather than having the
       | functionality of one being basically completely replaced to act
       | as a fancy sensor for a software controller to know how much
       | regen to apply. It's still great for these concepts being
       | explored, and we're lucky to have a company like Grin
       | Technologies in the aftermarket segment that are actively
       | researching innovative new ideas.
