This bike was bought and never ended up being used! It has some minor scratches from storage, but otherwise is like a new bike! It has a Shimano shifting system with 21 speeds. The frame is aluminum, which is the lightest metal used to make bicycles. This bike has comfort oriented riser handlebars. It has mounts to add a water bottle cage if desired. It also has a step through frame. This bike has 26” wheels (the front wheel has quick release). The seat also has quick release. Great bike for trail rides, commuting or recreational riding.
