Review the 3-D designs of the Fat Tire Rim / Tire Design. As you can see, I have completely changed what every other fat tire manufacturer is doing. Others allow the tires width to dictate the tires height, where current tires are approximately 110 to 120 mm wide and 100 mm+ in height.
This causes two issues:
First, it causes extra weight in the tire giving you additional mass to rotate.
As you can see in this 3-D Design of the bike frame with newly designed wheel system, I have now resolved and patented the balance of the issues with Fat Tire Bicycles.
Many, if not all, Fat Tire Bikes just 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. Therefore you can have any size crank arm length and this crank arm is still out of interference with the Chain Stay or Bottom Rear Fork.
