I wasn't comparing it as much to the TSDZ2, which does have crappy bb bearings (my stock set lasted 700 miles) that can be replaced with higher quality ones in house for relatively pennies or replaced entirely for under $300, as to how the bike above relates to my needs and bank account. If there is a much cheaper way for me to get my ya ya's that in my mind closely imitates the higher price spread (the torque sensor on the TS does a fine job IMNSHO) I am first in line. But I am perfectly happy riding a converted 15yr old steel hardtail so there is that to consider.
At some point when the Bafang M600 comes out in a format that I can get behind I will go with that option. While the Ultra is more powerful, like the TQ, it is porky and I don't need more power over lighter overall weight. There is no way I would consider a 61lb. bike over a 45lb. one for how and where I ride.
