I suspected that might be the case, or that it didn't succeed after it was introduced, since I wasn't able to find any more recent references to it. So I'm wondering if there is something available now to meet my needs.
The SmartRim looks good for my needs but the only information I can find is from when it was introduced in 2015. Does it still exist? My problem is hitting curbs and damaging my right front tire. I would like a camera that would alarm me when I'm close to such a curb.
