I am 54 going on 12, and just learned to ride a bike a few months ago. Been riding 20-30 miles/week mostly on mountain bikes. My problem: If I lift a hand from the handlebar, I lose control. This means that I can't safely signal turns or stops, or wave. Or take a drink. And as for fiddling with the downtube shifters on my old road bikes--forget it! I took a spill on my Premis trying that.
What am I doin' wrong?
Next hurdles: learning to "honk" and to use toe clips.
