I recently bought a Park N Move which I thought would be ideal with my garage situation. I never have a problem putting my bike on the center stand but yesterday when I tried my new Park N Move I couldn't get the bike to budge. I feel silly, at the demo the salesman (who is half my size) had absolutely no problem putting the bike on the dolly. Do the shocks have to be fully charged first? My tire pressure was 41psi front and back. What am I doing wrong? Put all of my weight on the center stand and lifted until my back just about gave out with no luck whatsoever. Very frustrating.
