We try to keep it on the down low but just built an almost complete Titanium bike (except for the sprocket bolt, pedal spindles and front spokes yet) by my company. For example the custom/prototype bars has already been tested for a year or so without problems cause it has thicker Ti tubes with half the chromoly weight and the whole bike is blowing minds here down in Brasil.
That's a BUS TiNerd Bike from BmxUS Ti brand by WebNerd! So before you get talking shit on that bike know that it has thicker

tubes, tt and dt gussets on, 5mm dropouts and 1.55mm titanium tubes. If you know bmx stardards you will know that 1.55mm thick tubes is very strong... Even its DT is ø 38.1mm x 0.9t* which normally it is ø 34.9mm x 0.9t* on chromolies DTs.
It whips so fast, I catch it in flight... also thrown in a cool baby's bike dice on front wheel just to play the game of BMX every time I want to...
