Thanks, I'm 5'3". I tried a 13" at REI and was told that was my size. When I stand over it I can lift it about 2" before my crotch hits the bar. My inseam is 31"

I will be riding on trials that have unavoidable rocks, and there will be long climbs. I live in the mountains. I do not plan on taking any big risk. If I hurt my hands I can't work.

I need a website for beginners looking to buy. There's so much "stuff" to consider.

Thanks for your help.
