Hope this hasn't been done before, but:
I just built myself a 1x7 bike to serve as a fair-weather commuter/weekend adventurer. It fills some sort of gap in my fleet of 3 -- between my nicer road bike (Merckx Corsa) and my "beater" fixed gear cargo bike. Curious to see what other roles 1-by-whatever drivetrains are filling in your stables.
Above all, wanting to see photos of these bikes, whether road, cross, commuter, gravel grinder, winter...
No pictures of mine, unfortunately, until after its maiden voyage tomorrow. Stay tuned!
