Trouble balancing when starting I recently starting riding again (stopped for 10 years) and am having balance problems when starting.  Using the proper starting technique causes me to wobble and lose my balance, tho' I haven't fallen yet.  As a result I've got my saddle low to the point where my toes touch the ground and I have too much bend in my knees.  Knees don't hurt, but I know this is not the right way to ride.  Any suggestions other than switching to a trike?
The more speed you get, the more balanced you will be, so at the beginning give a hard pedal stroke to get quickly some speed. You can also practice in a slight downhill road, this gives you speed easier.

I recently taught a friend to ride a bicycle (30 years old!), and the solution was the slight downhill.

Another trick is to look far ahead (dont look at your front wheel) and stay upright, so you should put your saddle higher than you describe.

Good luck!
