This bike says on the frame it is a 17" men's bike but, it was owned by a little old lady who rode it very little. 21 speeds, shifting works like new. Braking works. Spring loaded seat post. This bike is probably 5-10 years old. One tiny front tire issue from sitting around flat for years, it does hold air and work and should be fine for a long time as is. Kenda tires. There is some mud on the tires that could be scrubbed off.
