Hello! I am traveling through the area and doing some hikes and exploring in the national park. I am wondering if anyone has a mountain bike or hybrid bike in a small size, like a small to medium frame and around 26 inch tires, that I could use for a week or a bit longer (from January 15th as I write this post)? I could pay you an amount we could decide or figure out a way to ensure to you I'd return the bike to you
