I have been steadily riding for about a year now, put on about 1500 miles in last year. I have however been riding a 7 year old Schwinn Sidewinder 2.6fs I bought from walmart over 6 years ago. Never had a flat, never adjusted brakes, never had gear issues, never greased it. Basically, this was not bought for the riding i want to do now. I live 200 ft from a 60 mile long bike path so feel its time to get away from an all terrain bike, and ride a more path/road style bike. The path itself is fairly smooth but does include a few railroad crossings and pot holes. Plus on days I feel lazy i may hop a couple of curbs, but suppose I coulddo without that. Problem is I dont know what is best. My local shops say a hybrid, but wondering if the upright style handle bars may be holding me back versus having the curved(dropdown?) style like on road bikes. I dont want to spend more than $500, so of course am limited. I am 5'9", 175lbs. Any suggestion would be greatly appreciated. Below are the ones I am considering.
