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

Christini all-wheel drive 29er fat snow bike mountain bike for ride to the South Pole

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.

Now, he’s built  a custom version of his 29″ hardtail to accommodate fat bike tires and parts to support an upcoming attempt to ride a bike to the South Pole! The frame uses his patented system that runs an axle from a gear on the non-driveside of the rear hub, through the frame to the headtube, then down through the fork. In this case, it’s a custom titanium fork built by Carver Bikes in Maine. The trick will be to keep all the moving parts, well, moving in the arctic conditions.

UPDATE: In other news, they’ll be cranking up a limited run of their standard 29er hardtail this fall, and an even more limited run of this frame with its wider BB and axle spacing for anyone dreaming of their own icy adventures.

The bike is being test ridden by professional athlete Kate Leeming from Australia in the snow and ice of Spitsbergen / Norway in preparation for a South Pole cycling expedition during the next Antarctic summer (December/January). (follow her on Twitter @Leeming_Kate)

  1. This is not going to be a solo, self-supported attempt like was attempted by Eric Larsen earlier this year http://www.ericlarsenexplore.com/ , since she will have a full TV crew, snowmobiles for guides, etc, but making it all the way by fat bike even with all this support would be a good start. I’d love to see Eric Larsen get a second crack at it with his self-supported purist style.

  2. Give props to Larsen, when he realized he wouldn’t make it there and back he turned around and rode out instead of getting stuck and requiring a dangerous rescue.

    Good luck Ms. Leeming!

  3. Yeah, what is it with these Antarctic people and their aversion to poagies?

    Also, I think she’s going to want a wider rear rim for more float.

    How cool would it be if the first person to ride to the South Pole was a woman?!

  4. @frank
    A wider rear rim will not grant more ‘float’.
    It would be just as cool if the first person to ride to the South Pole was a man!!

  5. Looks like a wider rim and tire would not fit the frame. It may be that the two wheel drive will negate the need for more float in the rear. Would she benefit from more weight distributed to the front wheel? Lower bar position? Drop bars? We Alaskans want to know! Please keep us updated.

  6. Unless 45NRTH and Surly have made special tires for this machine than it is not a 29er. The tires on this bike are only available in 26in. Hopefully Christini does intend to make a replica of this frame and a 29er in either hard tail or full suspension.

  7. That’s Christini’s fork, actually.

    There wasn’t enough clearance for a Clown Shoe in the rear, unfortunately.

    The Christini was a breeze to build and works great, psyched to see the project worked out.

  8. Looks to be a perfect application for this tool. I would think with a lighter person and typically hard snow that a wider rim or tire may not be a huge advantage. I can definitely see where the two-wheel drive will be an advantage though.
    A 29er frame will be the same size as a 26″ fat bike. The 26″ fat tires actually will run a little larger diameter than most 29er wheels because of their huge volume.
