The most popular gear ratios are given below and most riders will choose a rear cog size within 1 tooth of those given below: 18:15 (1.2:1 – the bike rolls 2.49 m (98″) for one complete turn of the cranks) for 26″ bikes. 18:14 (1.286:1 – the bike rolls 2.46 m (97″) for one complete turn of the cranks) for 24″ bikes.
29″ and 26″ mountain bike wheels. 29er rims have an interior diameter of 622 millimetres (24.5 in) [1] and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire ...
It has been called "Raleigh Pattern" and "Westrick". They are noted for their strength, and there is also a Schwinn Bicycle Company copy of this design. [3] Westwood profile rims are most commonly seen in sizes 635 mm (28 in × 1 + 1 ⁄ 2 in or 711 mm × 38 mm), also marked 700 B, [3] but they are made in most of the middleweight sizes of:
The city bike differs from the familiar European city bike in its mountain bike heritage, gearing, and strong yet lightweight frame construction. It usually features mountain bike-sized (26-inch) wheels, a more upright seating position, and fairly wide 1.5–1.95-inch (38–50 mm) heavy belted tires designed to shrug off-road hazards commonly ...

Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a bike handles. [1]
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 ...
