The Ultimate Brakeless/Front/Rear/How many brakes? thread

I will just use my assumption based physics (what can go wrong with that)
If you read the post then it won't be assumption based!

This is the reason I wrote it in the first place because you are only seeing half the effect. The second half is not quite as obvious and is entirely dependant of the height of COG.

A body of weight further away from the point where the front wheel touches the ground is going to take more effort to lift due to basic leverage.
Right

Centre of Gravity doesn't matter
Wrong! You've just told me it does matter (horizontally) in your last statement.

If the rider sat 100 metres back from the front wheel it doesn't matter how much higher they are sitting, they are not going to be lifted as easily.
Wrong. If the seat was 200m high then it would be considereably less stable than a normal bike.

There is only 1 equation to compare the different situations (the first equation for deceleration in the post), and it's very simple (calculates acceleration/ deceleration but that's essentially the same as stopping distance).
