Wanted: Item received

Hi. I live in Ewell and have an exercise bike for sale for 30.00. It is listed on this site for sale already. It is an excellent bike but for some reason the odometer turns on but doesn't register movement. Still a very good workout and a good solid bike. Someone more technically minded might be able to fix it. It also has a tablet/phone holder on the handlebars, and a water bottle holder on the frame. I would be happy to deliver for a small fee. Let me know if you're interested. Thanks! Emma
