Quoted from rai:OK I was looking maybe the not that much trouble to switch wheels off.
You have the two big wheels. A threaded rod between them with a big turn buckle. Turn that to unscrew or tighten. Unscrew and pop the wheel unit off. Hold them in place and retighten to have them back on. Maybe a minute of work. Easy. If the turn buckle is too tight to turn, stick a big screw driver or something inside the slot in the turn buckle for added leverage.
On my regular two wheeler. I used a black magic marker to mark where I wanted them, high or low, for what was best for my use.
