I'm trying to remove the pedals from a Vespa Ciao right now and I'm having difficulties. I was told to remove the left pedal arm and tap the assembly through the bike in order to remove it. However, there is a little washer that is flush against the body of the bike (on the pedal assembly on the left) that keeps me from tapping it through the frame of the bike. It would seem like the washer would have a notch in it to remove it, but I don't see any way to take it off. Anybody have experience taking Ciao pedals off? Thanks.
