Freeride bikes are lighter than downhill bikes – which enables them to be ridden not just downhill but through more technical sections, such as North Shore obstacles, and allows the rider to pedal back up for another lap, instead of requiring a shuttle or chairlift. Most freeride bikes feature slightly steeper headangles and shorter ...
Coil, elastomer, and air-sprung suspension systems have all been used on recumbent bikes, with oil or air-damping in the forks and rear shock absorbers. The maturation of fully suspended conventional mountain bikes has aided the development of these designs, which often use many of the same parts, suitably modified for recumbent use.
CROW Design Manual for Bicycle Traffic is a publication on bicycle transportation planning and engineering in the Netherlands. It is published by CROW, a non-profit agency advising Directorate-General for Public Works and Water Management formerly Ministry of Transport and Water Management (Netherlands) .
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 ...
Road bikes usually use 68 mm (2.7 in); Italian road bikes use 70 mm (2.8 in); Early model mountain bikes use 73 mm (2.9 in). Later models (1995 and newer) use 68 mm (2.7 in) more commonly. Some downhill bikes even use an 83 mm (3.3 in) bottom bracket shell. Snow bikes use a 100 mm (3.9 in) shell.
Most bikes have positive trail, though a few, such as the two-mass-skate bicycle and the Python Lowracer, have negative trail. [ 12 ] Trail is often cited as an important determinant of bicycle handling characteristics, [ 13 ] [ 14 ] and is sometimes listed in bicycle manufacturers' geometry data.

Since track bikes have a fixed gear, braking can be accomplished by reversing the force on the pedals to slow down, or by locking the pedals backwards and inducing a skid. Fixed gear road bikes may also lack brakes, and slowing or stopping is accomplished as with a track bike. Many fixed gear bikes however are fitted with a front brake for ...
