If you want to allow very slow passive going over the edge, then you cannot have a high initial drop. The bike will just flip over...

A simple test for this (at least in principle) would be to test how cool the room "feels" subjectively versus its objective temperature...

So taking all the messy physiological arguments out of the equation, place a thermocouple in a closed environment, and turn on the fan...

So the drop height (minimum the rider drops) here is like a third of a meter here in these graphs? If the moment of inertia is low the...

@erobz I have experimented with the approach above a bit. I'm getting the impression that the inverse relationship of ##\omega## and...

@berkeman I'm in the grey shirt. This is Mt. Creek Bike Park in New Jersey. This is me coming off of a pretty nice sized drop...

To me personally it feels like you are initiating pedaling (in a high gear), while leaning back simultaneously. It puts a "smooth"...

I don't have youtube for videos, but maybe I can get some still frames. :smile:

Usually we don't do this unless the drop landing in not developed (or underdeveloped). For instance if you are jumping from the top of...

I'm getting ## \omega = \frac{L^2 mg}{(mL^2 + I)v } ## otherwise ( the factor of ##2## )we align on the approximation. Never mind. I...

The thing is you want to do less of this as the drops get large. You want to get the speed correct and let the physics do the rest for...

@erobz Another numerical solution approach: - Define a vector field, by assigning each point in space the orientation of the bike during...

I don't do much in the way of jumps or dropoffs on my MTB now (mostly XC and climbing), but obviously did lots of jumping in my...

An analytic solution would be difficult, but there is a numerical solution. Start with the highest possible take-off velocity and...

Basically that is what I was hoping for. Ignoring the actual bike geometry (treating it as a point), that the tangent of the landing...
