I feel your pain Bethany. I just started on clipless pedals a few weeks ago and for a few days, I was afraid of my bike. I fell the first five minutes riding, but haven't fallen again since that first tumble. My elbow is healing well thanks.

I am short legged and I also cannot reach the ground when I am on my saddle. When I stop, I stand on my pedals and unclip the foot that I indend to step down on. This being said, don't go changing your mind about what foot you are going to step down on at the last second. That is how I took my first fall.

If you aren't feeling secure on your bike, go back to your platform pedals until you feel more "one with your bike". It is better to just ride right now and worry about form and distance later. If you aren't riding because the clips make you nervous then you are losing ground.

I have to say, I love my clipless pedals now, but I am still talking to myself when I stop. Hang in there.
