I am looking to get into riding for exercise and for fun in NYC. I am 5'10, 300lbs and a woman. I have no idea what kind of bike would be good for a not very strong beginner. I am pretty proportional weight wise, so there shouldn't be problems unless a bike is really tiny (ie no belly in the way, just fat all over lol). My legs are quite long though. My commute to school is about 2.5 miles of city traffic in a busy part of town.

Any bike suggestions, or any other suggestions would be highly appreciated.

Thanks!!!
