Used Trek 820 Mountain Bike
This is an entry level mountain bike. This is more of ride around town and the campsite dirt road sort of thing. You aren't going to bomb down a technical trail on these.
This is a small 16" bike. Probably 5' 3" - 5' 7" and up. Very low standover, so may fit a smaller young teen-ish person. It is a WSD - women's specific design - which means wider saddle and narrower bar which I believe would be welcome for anyone this size, riding this kind of bike.
This bicycle has been refurbished to the Blue Tag standard which includes a 30 day warranty. For more on Coco's color coded refurb standards, click.Coco's is a local bike shop, primarily selling local bikes. Dis-assembly, packing and shipping adds a hefty $150.
