OK, how about lowering the saddle to the point where your feet can touch the ground ... flat, not just your toes ... and removing the pedals. Then scoot with your feet. Then if you feel like you're falling, just put your feet down. Yes, I'm serious about this. And practice using the brakes so you don't run into things.

If you can, go to a park, a quiet country road, or a local MUP to try this. You need more than just a small apartment parking lot to work on this.
