The Xtreme Fat Tire bike frame with its newly designed wheel system, we have now resolved and patented (#61/962,906) the balance of the issues with Fat Tire Bicycle.
Most manufacturers of Fat Tire Bikes took a standard bicycle design and tried to adapt it to fit a Large Tire and Rims. This system does not work for many reasons:
As you widen the BB and Crank Arm distance to get wider wheels, you impact the riders Q Factor and therefore his efficiency and ability to adequately cross train between different types of bicycles.
The Fat Tire Industry’s Bike Design forces them to continue to widen the BB width as the wheels and tires get bigger. By taking the Chain Stay or Bottom Rear Fork out of the equation, as shown, the whole system is out of a 220 mm rotation around the BB.
This system allows my current Wheel / Tire System to work more efficiently with no future extensions on the BB. It also allows all existing Fat Tire BB / Crank Systems to work on this frame. In addition, this system will allow an even wider tire up to 6”+. Plus, it also works with our newly designed 29er wheel system.
This patented system can also be used to create a Full Suspension Fat Tire Bicycle. This system creates less rotational mass, better rotational speed, and maximizes the bike and the bike rider’s co-existence with high efficiency, with out affecting their cross training between different types of bikes: (Road, Trail, Mountain, and Time Trial).
