2021 New Santa Cruz 5010 Small (Used)

My mom is selling her mountain bike, she bought it right before some serious health problems began. So she never was able to even take it on the trails. She has only ridden around the neighborhood 2 or 3 times. The amount of use on this bike is no different than a bike for sale at your local bike shop being test ridden, in fact probably has been ridden less. It just sits in her house all year round looking as good as it did the day she bought it. This is a small frame. She bought it brand new for 5500$ back in 2021. I believe she is asking 4900$ in my opinion anyone under 59 would be able to enjoy this bike on all terrain. Im 511 and I would have size issues on the trail Im sure.
