Mountain Bike Sizes?

My road bike has a 24" frame, and I can just stand over it with the top tube between my legs. When I ride it, my legs are straight at the bottom of the crank rotation, which gives good leverage while riding up hills. The mountain bike that I ride (bought used) has a considerably smaller frame, and even with the seat as high as it will go, my legs are still bent at the bottom of the crank travel. Makes riding up hill tough unless I stand up and pedal. What is the "standard" for mountain bike sizing, and do they even make mountain bike frames as big as 24"?

Hi, MTB frames are smaller than Road bike frames as their geometry is completely different. You can find MTB frames from 13" to 23"; in my case, I am 6'3" and I fit well in MTB 19" or even 21" in some brands of 26ers.
Your leg shouldn't be straight at any moment while pedaling, in fact the way to set your saddle height is being sitted push the pedal with your heel so your leg is straight, that way you make sure your leg is a little bit bend while pedaling.
The app SizeMyBike for iPhone and ANdroid could help you to find out which size is ok for you or you can use this link http://www.ebicycles.com/bicycle-too.../mountain-bike.
