thinest piece of metal i have seen

6 weeks after the arrival of my bike and the shoddy assembly i have to report that its true. the bike has had major issues.
at a speed of around 12 miles an hour, on a flat piece of road, my rear Derailleur carrier bracket snapped.
Causing my carrier to drop and enter the spokes jamming my wheel dead.
you can guess the rest.
Helpline - you have had it over 4 weeks.
repair man - i have seen thicker brackets on kids bikes.
the rest of the story i wont relate here.

thanks and goodbye
