WebbSince the vector from the rear to the front wheel defines the vehicle forwards direction, this means that the “forwards vector” rotates with angular velocity Ω z. If we define the state of our bicycle model as ( x, y, θ, v), then it has the nonlinear dynamics d d t ( x y θ v) = ( v cos ( θ) v sin ( θ) v tan ( δ) / L a)

WebbFor decades, riders have assumed that stiffer frames were more efficient, and thus faster. At the same time, physics tells us that a lighter bike is faster uphill and in accelerations. Stiffness and weight are conflicting goals: To make a frame stiffer, you need more material. To make it lighter, you need less material. WebbThat's the cost of the materials, not including labor.
