Why spent a lot of money on a new bike when you can get a great reputable bike at a fraction of the cost. This is a very good quality “Comfort” bike – sit upright, great suspension. 18 speed. 26” outside tire diameter. Easily adjusts for height. Rack over back tire. Was $600+ new, has been gently used and is in excellent condition. See the link below for al the technical specifications. Rated at 5 out of 5 stars. https://www.specialized.com/ca/en/expedition-sport/p/106353?color=195721-106353
