the influence of the position of the center of pressure of wind forces coming from the side is eliminated; the wheel flop effect (see below) is eliminated; Skilled and alert riders may have more path control if the mechanical trail is lower while a higher trail is known to make a bicycle easier to ride "no hands" and thus more subjectively stable.
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 ...
A KTM dirt bike with a paddle tire. Off-road motorcycles, also known as dirt bikes or scramblers, specially designed for off-road use. The term off-road refers to driving surfaces that are not conventionally paved. These are rough surfaces, often created naturally, such as sand, gravel, a river, mud or snow.
Unlike other wheeled vehicles, the primary control input on bikes is steering torque, not position. [8] Although longitudinally stable when stationary, bikes often have a high enough center of mass and a short enough wheelbase to lift a wheel off the ground under sufficient acceleration or deceleration. When braking, depending on the location ...
The drivetrain of a flat bar bike often borrows features from multiple bike styles, pairing the trigger-shifting approach of mountain bikes with the taller cassette ratios of road bikes. The brakes of purpose-built flat-bar designs tend to be linear-pull, a mechanism nonexistent in road bikes and largely displaced by discs with mountain bikes.
MX racing bikes have often been used as platforms for building enduro bikes. [1] This was partially driven by the conversion of MX from 2-stroke to 4-stroke engine designs to comply with regulatory trends, as well as the development of hybrid competition races such as Enduro-X. [1] Compared to MX bikes, enduro and dual-sport bikes traditionally had a much higher proportion of 4-stroke motors.
Hybrid bicycles blend characteristics from more specialized road bikes, touring bikes and mountain bikes. [1] The resulting "hybrid" is a general-purpose bike that can tolerate a wide range of riding conditions and applications. Their stability, comfort and ease of use make them popular with novice cyclists, casual riders, commuters, and children.
The women's motocross league is separate from men's motocross because of the different rules, and also the different bike sizes. Women generally race bikes that are 125cc or 250cc because they are not big enough to ride a 450cc. [1] These differences make it hard for men and women to compete together however it is done and is allowed.
