Whoever Brose are, it sounds like it's more their motor with a Continental badge stuck on it. I'm not sure a tyre manufacturer inspires any particular confidence in a crank drive system. However more competition is always good.
I like the simplicity of the concept and it's internal belt drive could result in it being the quietest e-bike motor yet outside of direct drive hubs. If coupled with a belt drive and NuVinci CVT on the bike it could have Rolls Royce like silence with owners wanting the quietest tyre tread design!
