Pedal on exercise bike fell off, not going back on My pedal came off my exercise bike/cross trainer. I have tried putting it back on, but the big screw will only go in so far.  It is turning twice then getting stuck. Can anyone tell me what I need to fix this. I don't know the names of the certain parts etc to search myself.
Which side pedal came off? This answer might help, pedals don't both screw in the same way.

If not, can you attach a photo? If you don't know the names we can help figure it out for you.
