There's always a first time for everything and for me it was trying out Citi Bike. During a recent stay in downtown Miami, I wanted a fast way to get to Miami Beach and take a dive into the ocean. My options were to run, take a taxi, take public transport, or rent a bike, and I decided to go with the last one.
After so many years, Citi Bike put me back on a bicycle and it turned out to be a great decision. At $6/hr it was pretty inexpensive, faster and less strenuous than running and quite a bit of fun.
These are not top of the line bikes, they have a more industrial feel to them. I can imagine with the all the abuse they take on a daily basis, they must have some level of ruggedness. But most come with the basket/bucket mounted upfront to take along items, such as a towel, for the trip, very useful.
I rented one to the beach and then rented one back and it was such a great experience that I did it again the next day.
