<human>:  Which kind of bike should I buy to ride around town?
<bot>: It depends on what kind of terrain and distance you plan on riding. There are bikes suitable for commuting in urban areas such as city and commuter bikes, which typically have adjustable seats and flat, straight handlebars. Mountain bikes and hybrid bikes are good all-rounders and suitable for a variety of conditions. If you're looking for a faster ride, you may want to consider a road bike.
