I have reached that. It took me 1 motor, 1 derraleur, 2 chainrings, 2 cassettes, 5 small rear sprockets, 2 front brake disks, 3 rear brake disks, 2 front brake calipers, about 6 rear brake calipers, maybe 10 chains and maybe 3 washes. Haibike, just like Trance has Yamaha motor. I saw some reports over 20000 miles on those motors and keep counting.
