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 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.
A motorcycle (motorbike, bike, or, if three-wheeled, a trike) is a two or three-wheeled motor vehicle steered by a handlebar from a saddle-style seat. [ 1 ] [ 2 ] [ 3 ] Motorcycle designs vary greatly to suit a range of different purposes: long-distance travel, commuting , cruising , sport (including racing ), and off-road riding.
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).

Proper positioning of the rider's hands according to the purpose and style of the bicycle. Providing a mounting platform for brake and gear levers as well as various accessories. Racing/touring and triathlon bars have additional goals: Enabling the rider to assume an aerodynamic position.
Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. [1] [2] It is sometimes called whitelining, or stripe-riding. [3] [4] This allows riders to save time, bypassing traffic congestion, and may also be safer than stopping behind stationary vehicles. [2] [3] [5] [6]
The cycling skills manual Cyclecraft, the foundation of Bikeability, the UK's national standard for cycle training, defines the terms primary riding position, where the cyclist will be more visible and predictable to motor vehicle traffic, as being in the center of the traffic lane, and secondary riding position as being 1 metre (3.3 ft) to the ...
