Shimano Alfine Di2

Electronic shifting comes to city bikes with the Shimano Alfine Di2 marriage of the high end Alfine consumer component set, with the previously road racing-only Di2 electronic gears. The core of the system is a sealed internal hub with a small motor that does the shifting—gone are manual gear shift wires, with the electronic wiring hidden through the frame, and the battery is installed out of sight as well, in seat post or downtube. The functional advantage is smooth, precise, one-finger shifting (there is no more front derailleur) and a wider gear range that encourage efficient gearing over the ups and downs of urban terrain. And it looks pretty slick as well. Options include 8- and 11-speed hubs, and push-button or control lever shifting for straight or drop-style handlebars. A tiny LED feedback unit indicates gear and battery level, and the Li-on battery is rated for 1,000 miles on a charge. Look for it this fall, on top tier bikes from various manufacturers, or as parts for custom builds. It’s a new definition for e-bike: plug in, juice up, ride.
