Update: July 2, 2015: Compass Bicycles recently began selling MKS US-B Nuevo Clipless pedals based on the Ezy Superior system. So if you want to switch between the Lambda–or any other Ezy Superior-compatible pedal–and a clipless pedal, now you can. (As far as I can tell, the only MKS clipless pedal available before the Nuevo used MKS’s Ezy system; as a result, it was not interchangeable with Ezy Superior pedals.)
Folding bicycles often come with folding pedals. Folding pedals reduce the width of the folded bicycle, but not as much as quick-release pedals, like the MKS Lambda with Ezy Superior coupling.
Here’s what you’re looking at in the picture: the pedal, the adapter that screws into the crank, the washer that MKS recommends using with any crank with a step down to the crank threads, and the right crank of my Bike Friday tikit, which happens to have that step down.
I slid the washer over the threads of the adapter, greased the threads and screwed the adapter into the crank arm. MKS is right: you can’t install the adapter with a regular pedal wrench. I used a 15mm cone wrench to do the job. Note the black stopper pin between the adapter’s outer cap and the crank arm.
Ready to attach the pedal? The outer cap is spring loaded. Twist the cap until the dot on the cap lines up with the black stopper pin.
Push the outer cap toward the crank, and hold it there.
Push the pedal into place. Release the adapter cap.
This is what the pedal looks like after installation.
When you release the outer cap, it springs away from the crank and rotates on the lower portion of the adapter. You’ll know the pedal is properly installed when you hear a click upon releasing the cap. Note that the black pin and the dot on the cap of the adapter are no longer aligned. You’re ready to ride.
And so am I, with one set of MKS Lambda pedals and two pairs of Ezy Superior adapters: one set for the Bike Friday tikit and the another for the Dahon Bullhead.
