The only thing you will have to do is keep tighting the freewheel, You will now when the freewheel is loose because the freewheel will make some funny clicks and will be a bit of a rough ride, so all you have to do, which is easy as you like, is: 1) Get a small allen key or screw driver. 2) Then, on the frame side of the freewheel, you can locate 2 little holes "on" the freewheel. 3) These holes you can use to tighten the freewheel. 4) So reach through the frame with a small allen key or screw driver and push the allen key or screw driver head into one of the little holes then peddle backwards. Job done, you will have to do this quite often (maybe 2/3 timnes a ride, depending on how hard of a rider you are) Any problems contact me at dizymazen@hotmail.co.uk
