I have MKS pedals on both my folders, and on my full size old Peugeot. I actually rotate the two sets of pedals between the three bikes - I have an SPD-style clippy pair and a more day-to-day caged pair. They're superbly made in my opinion - good engineering, good bearings and really great for super-smalling the bikes on trains and busses. Expensive, yes - but all good pedals are.
