You won't have a problem. The bike is designed to be useful for everyone, including little 90-pound women. The three gears are all very low. As I said before, third gear is low. Second gear is extremely low, barely useful for me. I use it to ride from a standstill for the next 20 feet, then I shift into third. First gear is a total joke to me, though I'm sure some find it useful. I'm fine with the setup how it is, because I'm not their primary target as a fairly athletic cyclist. You will probably find yourself riding the bridges in third or second gear. If you get super tired, you can still use first.
