    Why is it called a bottom bracket?

    Ok so it's near the lowest part of the bike, but it doesn't seem to be a bracket at all. i.e.

    Furthermore, why call it a bottom bracket when there is no top or higher bracket to distinguish it from?

    a. A simple rigid structure in the shape of an L, one arm of which is fixed to a vertical surface, the other projecting horizontally to support a shelf or other weight. Imagine your crank arm connected to the spindle, this forms the L shape, also an older term for the bottom bracket is bottom hanger

    I'm curious, how do you steer one of those, is it a 'twisty action' like a normal (?) bike, or a side to side movement like a boats rudder ? The only one I recall seeing in the flesh had low bars.

    P.S. not sure, but looks like your pointing in the picture below the damp proof course needs a touching up :blush:

    Side-side, the 'stem' is actually called a tiller.
