I think it's a great price, especially for the low mileage.
If you decide to pass it up, please send me the details 😂.
I have one and I absolutely love it.
Bike correcting itself while riding is going to feel seriously scary. It might make me lose control. I find it very unnerving to sit on a bike that doesn't move as I'm expecting it to, like when someone is tilting keeping it upright or pushing / pulling it.
