BOSCH eBIKE SYSTEM

$4,000 and up

Making the bike commute easier

Bosch eBike Systems are designed to make pedaling to work easier. The company, a German manufacturer of automotive parts and electronics, has turned its expertise to bicycles, working with such cycling brands as Cube and Haibike to make powered bikes that are sold by independent dealers. Bosch components include a power pack and charger that can last up to 100 miles, a drive unit that delivers a boost of power and an onboard computer that allows ­riders to track data and switch modes. Five drive modes give a different level of power. For instance, the sport mode provides an immediate burst, which is good for city traffic, and the tour mode provides steady support, which is suited for longer rides. Bosch does not make retrofitting kits, however, so riders need to visit an independent bike dealer to buy one outfitted with the eBike System
