+1 never heard of a folding pedal before now
just looking at them on harris cyclery now. depends on what bike you have i'd suggest any sort of downhill or dirt jumping pedals cos they would be made to take a beating. but if its a lightweight road bike you have i'm not sure. i have a pair of Looks on mine that are literally 15+ years old and still going strong
glad you made it back ok though. yeah one leg cycling is not that fun really. ha ha
