Christini have patented a mechanical AWD system for bikes. Unlike hydraulic systems tested by other manufactures, Christini’s AWD delivers power to the front wheel through a series of chains and shafts. When the bike’s rear wheel loses traction, Christini’s AWD system engages immediately, and transfers power to the front wheel until the rear wheel grips again. For optimum conditions, where traction is not an issue, the Christini AWD front hub is equipped with one-way clutches, which allow the front to freewheel.
In addition to added traction, the main benefit of the Christini AWD system is better high-speed cornering. With a driven front wheel, the tendency to ‘wash out’ and ‘tuck in’ is greatly reduced, allowing the bike to be ridden harder, faster and with more confidence.
