I'm 5'2"... in the morning... and under 110. Size doesn't have to do with getting up hills. actually, being smaller, and having a larger power to weight ratio is good! little people have less to push up big hills! Its just getting that power up that is hard at first.

I am limited in my ability to change my bike's components. My bf made me a bike from his old stuff. so I have a double with... maybe a 12/25 cassette (possibly 12/23)? Basically.... there is no spinning on hills for me.

I basically push my pedals just enough to keep me upright. I've been told that as long as you're moving forward you should be able to stay upright.

I'm learning that going up hills, with my bike components, is SLOW, PAINFUL, But doable.

In all honesty, i hate it. The first couple of times riding I panicked and hyperventilated and cried. I didn't realize that I couldn't just sprint up a hill to get it over with. It's really psychological for me.

Also, if your gears DON'T go low enough, the low repetition high resistance will build the leg muscles to do everything better on the bike.

You should take my advice with a grain of salt. I mainly regurgitate advice given to me. But I thought I'd give it to you and let you know you're not the only one to suffer and struggle up hills.

I also think the most times I've fallen over has been trying to go up steep hills.
