I want to share my commuting/fun bike build. It picked up a 2009 Fuji Tahoe Comp 29er with a medium from Craigslist with the intention of an eMTB conversion. I originally had an Ozark Trail Ridge running this motor, but I punctured the frame by not having a spacer between the motor and the frame.
I was limited on choices because I wanted to use both my ToSeven DM-01 with torque sensing and the 60V 25Ah triangle battery (Samsung 35E cells). The motor requires a rear triangle that lets it not position the chainring too far out, resulting in a terrible chainline. Since the initial conversion, and one torque sensor failure, I've made more upgrades to the bike.
I've posted some of this in random threads here and there, but I figured that it makes more sense to have one consolidated build thread.
Bringing the bike home.
The bike was mostly stock spec except for a PNW dropper post. SRAM X5 derailleur and shifter, Avid cable disc brakes.
The chainline is much better than it was on the OTR build. I need a chainring with more of an offset dish as I have an additional 12mm available before it's too close to the chainstay... like the 42 tooth that came with the Tongsheng TSDZ8 that I have on my workbench.
I did not want to puncture another frame, so I made a spacer/brace out of JB Weld and used grease on the surface to prevent it from bonding to the frame or motor.
The initial build was fun, but most of the components on the bike were worn and not really up to the task of handling the 1000W DM-01 with the exception of the Avid disc brakes, which seems to work well enough.
So many settings to play with.
I eventually had a torque sensor failure, so my motor was replaced. After a small hiatus, I started making upgrades again.
I upgraded to a Shimano Cues cues setup with RD-U8000 derailleur, SL-U8000-11R Shifter, CS-LG700-11 Cassette, and CN-LG500 chain. I also ditched the Rockshox Dart 3 with 28 mm stanchions for a spare Suntour XCT30 with 30 mm stanchions. The ride is so much more stable at speed and enjoyable, I'd have to measure to see if the Suntour fork has less off offset at the crown and more at the wheel, but it looks like it. I also swapped on the wheels from my Ozark Trail Ridge since the hubs and tires were in such better shape (new). The bike feels amazing. The lack of rebound on the Suntour is irritating, but I may swap in a Wolftooth GeoShift 2 degree headset with a Rockshox Recon when I have more money to burn. The Avid brakes, while serviceable, were replaced with Shimano MT200 hydraulic brakes.
After swapping from a 90 mm stem to a 60 mm unit.
More to come.

. If I recall correctly, a selling point of Cues is the same pull ratio and high compatibility along with Linkglide shifting.
