The measurement is considered positive if the front wheel ground contact point is behind (towards the rear of the bike) the steering axis intersection with the ground. Most bikes have positive trail, though a few, such as the two-mass-skate bicycle and the Python Lowracer, have negative trail. [12]
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 ...
This was intended to offer an even more aerodynamic position, due to low and narrow placement of the hands, than just the drops, while still remaining legal for mass-start races.

Old-style tank shift. Regular clutch hand Shifter - This is where the shifter is a regular knob either located on the tank, which operates through a linkage to the transmission (tank shifter) or on a lever bolted directly to the top of the transmission (jockey shifter or slap shifter depending on the transmission design) and involves the semi-complex task of foot clutch operation and hand ...
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 ...
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]
