Any bike its fun to ride, price depends on your needs and a how much youre willing to spend, speed depends on how strong you are and the amount of gears.
I live in a fairly hilly city, but most of the places i have to go are on flat places like the centre, and here its hot too, my bike its a steel framed, single speed with pedal brakes and a rack, i didnt want to spend much on a beater so i build one.
