What bike should i get for riding on the side of the highway/intown?

Hybrid bike. it is cheaper and is meant for the riding ou want to do. no mountain bikes, the big tires make it harder to pedal around in the city. a hybrid bike doest use the big knoby tires and shocks. hybrids are meant for city riding and are comfortable too. dont get a road or racing bike, as it probably wont hold up. good luck. (hybrid bikes may not sound common, but there are more popular actually than mountain bikes)
