Aluminum Jonny's EZ3 Leaner His main issue now is how to lock the leaning mechanism at stops It seemed tricky to attach any sort of clamp to the wobble bar itself. He tried a longitudinal brace from the main frame to one of the swingarms with a quick release clamp to lock its telescopic sliding action. Someone recommended a shock with a lock-out setting, but he has tried it with some damping and that is NOT a good thing to have on this design. Tim and others recommended a disk brake (perhaps cut down partly) attached to one swingarm with a caliper on the main frame. One brake might suffice, though if there is a lot of suspension action (which would let one side still move while the other was locked) he might need to do it on both sides.
