A couple of weeks ago I had to remove the pedals from my bike and I struggled big time. I followed this video for instructions and it was very good. As I didnt have enough time, I only managed to buy the standard spanner key that fitted the screw but that key didnt offer me enough leverage to actually remove the screw and no mutter how hard (or I am not strong enough), I failed. I decided to go to a nearby bike shop and they were nice enough to unscrew the pedals for me in 3 sec… using a pedal spanner like the video. So maybe I need to get one of those for the future (and remember how to actually remove the pedals).
