I have a mountain bike and it was working well.then I started to pedal and the back wheel isn't moving.could someone tell me what it could be?

  • A few more details would help. Does the cassette move? – Gordon Copestake Jul 27 '15 at 13:48
  • Does the cassette just spin? Does it still click when you spin the wheel? If it is spinning and a freewheel then not a lot you can do. If you have a freehub it might just be gunked up. This is a good video on how to service a freehub. youtube.com/watch?v=f19BGYc5ysA It that seems like too much then just take it to a bike shop. – paparazzo Jul 27 '15 at 15:54

    Is there a chain on the bike? – jqning Jul 27 '15 at 20:44
  • There is a chain. – Garcia Aug 5 '15 at 16:34
  • Does anyone know about how much it would cost to fix it – Garcia Aug 5 '15 at 16:35

One possibility is that the hub's freewheel mechanism has broken. Maybe it's fixable with some spare parts or you may need a new freewheel hub body or a new hub altogether. Your LBS will be able to assess the situation.

    It might be fixable just by cleaning and lubing – paparazzo Jul 27 '15 at 15:07
