  2. Bicycle and motorcycle geometry - Wikipedia

    en.wikipedia.org/wiki/Bicycle_and_motorcycle...

    Due to front fork suspension, modern mountain bikes—as opposed to road bikes—tend to have slacker head tube angles, generally around 70°, although they can be as low as 62° (depending on frame geometry setting). [3] At least one manufacturer, Cane Creek, offers an after-market threadless headset that enables changing the head angle. [4]

    en.wikipedia.org/wiki/Mountain_biking

    Mountain biking (abbr. MTB) is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes.Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials ...

  4. Bicycle performance - Wikipedia

    en.wikipedia.org/wiki/Bicycle_performance

    From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).

    2020 full suspension mountain bike. A mountain bike (MTB [1]) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which often makes them heavier, more complex and less efficient on smooth surfaces.

  9. Bicycle and motorcycle dynamics - Wikipedia

    en.wikipedia.org/wiki/Bicycle_and_motorcycle...

    Normally, road racing bicycles have more trail than touring bikes but less than mountain bikes. Mountain bikes are designed with less-vertical head angles than road bikes so as to have greater trail and hence improved stability for descents. Touring bikes are built with small trail to allow the rider to control a bike weighed down with baggage.
