That looks like a very tight fit! I'm wondering if there are some subtle differences between the frames that lets the tsdz2 only fit som Bullitts? Let's hope not. The welds on your frame look very big. Perhaps you could make it fit by carefully knocking a few dents in your frame? Or maybe not on such a nice new bike.thomfellow wrote: ↑Jan 12 2018 11:13amI purchased a Bullitt in December (2017) and ordered a TSDZ2 a few days later and after my first installation attempt I don't think it's possible to use these two together anymore. I'm not sure if I'm missing something or if the design of one or both have changed such that, even with significant grinding, they will not be compatible. I may be overly pessimistic.
I'm curious if anybody that's done this recognizes how tight this looks and thinks I'm just not visualizing it properly. To my eyes it doesn't look like I can remove enough material to make it clear. I may make another attempt this weekend. (see attachments)
I see that @Dr.Electric says they had to remove nearly all of the mount, as well as is illustrated by @mscoot.
Wondering if the clearance I'm seeing looks familiar matte2k@? The photo you show seems to have more space than mine.
Anyway, my frame is an older one from around 2010. After completely grinding away the rear mount of the motor and also grinding away the holes for the securing plate on the left side, it will slide right in and I can wiggle the motor back and forth a couple of mm. There's even a bit of room left for a piece of rubber.
Tomorrow I'll be doing a major overhaul of the motor after my torque sensor imploded and caused havoc to the internals of the motor. I'll take some pictures of how the motor sits on frame. If you want me to take some measurements, let me know and I could try to do that as well.
While my older bullitt has been out of order, I've been using a newer eBullitt as my daily ride. It's interesting to compare the two motors actually. For what it is, I think the Tsdz2 does quite well against the shimano steps. Tsdz2 (250w euro version) is a more powerful motor. Initial power from start is higher, but the Steps seems to hang on to that power for longer. There where hills I couldn't climb with the eBullitt that my tsdz2-bullitt would tackle with ease. The torque sensor on the tsdz2 also seems to play a bigger part in how much power the motor puts out while the steps in full power just wants to accelerate. Di2 shifting is nice, though.
