I am a 57 Year old Man. I live near the beach. I am planning to buy an inexpensive bike ($150 to $250) that I plan to ride each

morning for about 10 - 15 Miles Per Day on mostly flat terrain (some road, but generally boardwalk and shore neighborhoods).

I expect I will want to time some of my rides to gauge improvement, but my rides will be a mix of light physical testing and general riding.

I used to Mountain Bike in CO and did long distance weekend rides (100 miles) as a kid on my 10 speed Schwinn.

I am 5'10 1/2" and currently 265 lb. I was thinking a single speed, or 3-speed, but I have no clue. Any recommendations would be appreciated.

I am even considering used (but it's such a hassle).
