I just stumbled upon this thread. I don't agree that changing the bike is the answer. You already have an extremely low gear. Have someone look at you while you climb hills on your bike. You can probably learn how to do it better. Unless you're old or disabled, you should be able to improve your climbing ability.

The trouble is, you've come to a mechanics' forum, so everyone provides a mechanical solution to your problem. But I think your problem is more of riding technique, not mechanics.
