Greetings bike guru's. My wife and i were cleaning out our storage area in the basement and discovered a bicycle. It is a Dutch-made Batavus Monte Carlo. It is green in color and under the layers of dust and cobwebs it is absolute mint condition. I couldn't find much online about the bike aside from the company makes mopeds. I do know it's from the 70s. Does anyone know if these are collectable bikes or if they have any value to them? The serial number is 3557395. Thankyou for your help.
