I don't want to discourage you
learning new tricks, but maybe you simply need to feel comfortable on the bike for a while before doing other things. That takes time so be patient with yourself.
Have you ever thought of getting a camelbak hydration system? Then you can drink on the fly and don't have to reach for anything!
Have fun, learn at your own pace, but do strive to better your skills as best as you can.
Happy pedaling!
Life is like a 10 speed bike, we all have gears we never use.
Charles Schultz
"The bicycle is just as good company as most husbands and, when it gets old and shabby, a woman can dispose of it and get a new one without shocking the entire community." — Ann Strong, Minneapolis Tribune, 1895
