Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length). This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent. But in ...
V-shaped bicycle stairway beside a short staircase Bicycle stairway within a vehicle ferry. A bicycle stairway is a pedestrian stairway which also has a channel alongside it to facilitate walking a bicycle up or down the stairway. [1] The channel itself is also often called a wheeling ramp, push ramp or runnel. There is no standard in the ...
For example, the Analytic Cycling calculator Archived 2022-01-15 at the Wayback Machine gives a time/distance advantage of 0.16 s/188 cm for a sprinter with 500 g lighter wheels. In a criterium race, if a rider has to brake entering each corner, then this is wasted as heat.
A new powered bike escalator in Paris, 2020. Bicycle lifts are powered mechanical systems for moving bicycles uphill. They are used where the steepness of a slope or other situations like subway crowds make riding uphill difficult. They are used on transit to make areas more accessible and reduce conflict.
The blue car entering the grade-separated road, and both the red and blue car exiting must both change lanes in the short distance provided. On roadways with grade-separated interchanges, weaving is a result of placing an exit ramp a short distance after an entry ramp, causing conflicts between traffic attempting to leave the roadway at the ...
A pram ramp with tactile paving that connects a sidewalk to a road. A curb cut , curb ramp, depressed curb, dropped kerb , pram ramp, or kerb ramp is a solid (usually concrete) ramp graded down from the top surface of a sidewalk to the surface of an adjoining street. It is designed primarily for pedestrian usage and commonly found in urban ...

Note that, on a bicycle, as rake angle increases, head angle decreases. Trail can vary as the bike leans or steers. In the case of traditional geometry, trail decreases (and wheelbase increases if measuring distance between ground contact points and not hubs) as the bike leans and steers in the direction of the lean.
