Looking for Techniques for Riding Uphill on a Single Speed I commute on a Single Speed (SS) bike about 13mi round trip. Going home is not a problem as the gradients are low and I can climb them. However, going in to work the gradients are much steeper and I have a hard time climbing them. I usually need to stop and walk a bit. I am looking for any pointers on climbing hills on an SS. Thanks

Edit: I am not really looking for ways to avoid hurting myself, I am young and fit so that isn't my biggest concern. I am more concerned with making my pedaling technique more efficient, especially for hill climbs. Another point I should mention is that I am using clipless pedals to increase my power output.

Verdict: I added this because I can only choose one best answer. I think that @GuyZee best addressed my question about technique, but @Steven offered a great deal of help with regards to getting a better mechanical advantage. Thanks to both of you for providing great answers.
I ride both SS/FG and approach climbing hills much of the same way I would if I were on a geared bike with one very big exception...MOMENTUM. When on a heavily geared SS/FG I gain as much speed as possible going into the hill and push hard to maintain it throughout the climb.

Basic climbing tips: 


Slide back on saddle and drive heels through the bottom of the pedal stroke
If you need to stand, do so while minimizing body sway and unnecessary counterproductive upper body motion
Get into a rhythm - climb at your own pace
Stay upright to keep lungs operating at full capacity
Pull handlebars into your thighs as you drive pedals forward


Hope this helps!
