Two-Wheel Drive Christini 29er Fat Snow Bike Developed for Ride to South Pole – Bike Rumor

If there were ever an application for an all-wheel drive mountain bike, this is it. Christini’s been making mountain bikes with two wheel drive for quite some time, starting development in 1995 and selling the first bike in 2001. He’s even ported the tech over to motorbikes.
