Don't know much about this - just helping an older friend declutter. It's a pretty looking hybrid bike, with an aluminum frame, 21-speed gearing, 27.5" wheels, and a front shock. Haven't checked whether the tires hold air. Two things I can tell you: The rear derailleur is not attached, and may need to be replaced. And this is a front disc, rear rim brake bike, so the front wheel you see is not the right one. I'll include it anyway.
