I am seeling a Rialto Classic bike. It fits adults around 5'6" to 6'0" confortably, unsure of the actual frame size, around 22". Rides smooth, brakes are good. Big comfy seat. Only issue (see picture) is that the plastic on the handlebar anchoring the twist shifter is broken. If you stabilize the broken part while shifting, it goes through all the gears smoothly. $150 Text or email if interested.
