Great bike for in-town trails or touring. Probably around 19" -- fits 5'9" person at pictured seat height, but has a very forgiving geometry and should accommodate a wide range. I believe the tires are 700x38 -- not so good for rocky single-track, but great for most gravel roads. Helmet, lock, tools included. You can keep it longer for cheap ($35 for a week, $80 for a month). Car rack is likely available at additional cost.
