with the 48/38/24 crankset and a cassette with 11-34t you should have low enough gearing to do anything you want. That 24 X 34t is a really low gear...probably only used on incredibly steep hills with gear.

You should be fine. For unloaded riding you'll probably spend most of your time on the 38 chainring and the middle of your cassette....at least I do anyway.
