Best for Speed Demons

BMC Alpenchallenge AC01 Alfine 8

At 23.5 pounds (light for a commuter), this is a fast and nimble bike thanks to a racer-inspired, steeply angled fork that aids handling. An eight-speed internal drivetrain provides plenty of power for climbing hills, and Shimano hydraulic disk brakes add serious stopping force, even on rain-slicked pavement. [$2,299; bmc-racing.com]
