Peace be upon you. This is a Cooper bicycle, size 20. It comes with a chain and I've had it for about a week. The price is 300 riyals. I'm giving you a special offer, and I originally bought it for 350 riyals. Goodbye. It comes with a free chain. And the bicycle is in the best condition. If you want to see the bicycle, send me a private message so I can send you pictures of the bicycle.
