- Hybrid bikes: a bike, usually ridden by someone in business attire coming home from work, or a casual bicyclist.
- Mountain bikes: ridden by people who either have no clue what they're doing, and bought their bike at Target, or who are serious offroading maniacs who love the sport.
- Vintage bikes: That classic schwinn or brooks or globe-y bike that older guys ride to get "in touch" with being young again. Likely in business attire or running shorts and a cotton tee.
- fixies: ridden by hipster artsy types
