    Increasing the rotational inertia of the front wheel by increasing the speed of the vehicle and the rotational speed of the wheel will tend to counter the wheel flop effect. A certain amount of wheel flop is generally considered to be desirable. Bicycle Quarterly magazine states, "A bike with too little wheel flop will be sluggish in its ...

    en.wikipedia.org/wiki/Aristotle's_wheel_paradox

    Aristotle's wheel paradox is a paradox or problem appearing in the pseudo-Aristotelian Greek work Mechanica. It states as follows: A wheel is depicted in two-dimensional space as two circles . Its larger, outer circle is tangential to a horizontal surface (e.g. a road that it rolls on), while the smaller, inner one has the same center and is ...

    When braking is increasing the center of mass m may move forward relative to the front wheel, as the rider moves forward relative to the bike, and, if the bike has suspension on the front wheel, the front forks compress under load, changing the bike geometry. This all puts extra load on the front wheel.

    Instead, they say "The amount of wheel flop is determined by the factor "f", the weight distribution of the bike, and an eventual front load attached to the bicycle's forks," and "Wheel flop factor "f" = b sin ∂ cos ∂ (b = geometric trail, ∂ = head angle).

  6. Bicycle wheel - Wikipedia

    en.wikipedia.org/wiki/Bicycle_wheel

    The front wheel from a racing bicycle. Bicycle wheel with wooden rim Nipples Spokes Cross-section of a rim A Shimano Dura-Ace freehub-style hub. A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels.

  7. Recumbent bicycle - Wikipedia

    en.wikipedia.org/wiki/Recumbent_bicycle

    These typically have two 20″ wheels or a 26″ wheel at the rear and 20″ wheel at the front. The seat is positioned between the wheels rather than above them. The extreme reclined position, and the fact that the rider is sitting in line with the wheels rather than atop them, makes this type the most aerodynamic of unfaired recumbents.

  8. Vehicle dynamics - Wikipedia

    en.wikipedia.org/wiki/Vehicle_dynamics

    Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.

  9. Wheel theory - Wikipedia

    en.wikipedia.org/wiki/Wheel_theory

    A diagram of a wheel, as the real projective line with a point at nullity (denoted by ⊥). A wheel is a type of algebra (in the sense of universal algebra) where division is always defined. In particular, division by zero is meaningful. The real numbers can be extended to a wheel, as can any commutative ring.
