Consider many of the bikes marketed as commuters, such as the Bianchi Milano, Electra Amsterdam, the Trek Urban series, the Gary Fisher Fast City series, the Marin Urban and Commuter bikes, the Giant Metro series, all of the Specialized Multi-Street lines, and more. The vast majority of these bikes do not have drop bars.
