Im a total novice to bike riding, and Im 56 years old. Hubby brought me home a bike yesterday and whilst I was able to get on it and ride it allbeit extreemly wobbly, I felt very unsafe as I honestly felt like I was doing 90 miles an hour. It felt like even the tiniest touch of the pedals seemed to get it whizzing along. This bike seems to go so flippin fast all on its own. How can that be? So can someone tell me how to make this bike, which has 21 gears on it !!! tell me what gears I should be in to make me feel like I have a bit more control of the bike. I would like to be able to pedal steadily and yet not be 'doing a ton' at the same time. Your all probably thinking what a wally I am, but Im not going to let this thing beat me. I rode as a kid, and just thought it would all come flooding back so easily, but this bike does not seem like my bike was when I was a kid, this bike seems to have a mind of its own. Help.
