How should I alight from the pavement?
Depending on what you mean by "should", you possibly "shouldn't" be riding on the pavement.

After parking or walking on the pavement, I move back onto the road in a way that's similar to setting off from/in a parked car.


Stand on the pavement/side-walk, side by side to my bike.
Lift the bike down onto the road, close to the curb, facing in the correct direction (i.e. with the traffic)
Look to make sure there's still nothing coming.
Mount the bike (standing on the side-walk, holding the brakes, swing one leg over and sit on the saddle, with the other leg still on the side-walk)
Now I'm on the bike, and the bike is on the road: stationary, and at the curb, and now ready to move off when traffic permits.
