Many bike rallys have a "slow race" where the object is to be LAST across the line, without touching your feet to the ground. That takes skill.
Another thing you might want to work on is starting from a stop - on a hill. That is definitely a situation you will run into out there. Find a gentle incline on a quiet street to start practicing on. I found it easier to hold the bike with the rear brake 1st, then work my way up to holding the front brake, and manipulating the throttle at the same time.
